Ataxia: Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharynx, larynx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.Cerebellar Ataxia: Incoordination of voluntary movements that occur as a manifestation of CEREBELLAR DISEASES. Characteristic features include a tendency for limb movements to overshoot or undershoot a target (dysmetria), a tremor that occurs during attempted movements (intention TREMOR), impaired force and rhythm of diadochokinesis (rapidly alternating movements), and GAIT ATAXIA. (From Adams et al., Principles of Neurology, 6th ed, p90)Friedreich Ataxia: An autosomal recessive disease, usually of childhood onset, characterized pathologically by degeneration of the spinocerebellar tracts, posterior columns, and to a lesser extent the corticospinal tracts. Clinical manifestations include GAIT ATAXIA, pes cavus, speech impairment, lateral curvature of spine, rhythmic head tremor, kyphoscoliosis, congestive heart failure (secondary to a cardiomyopathy), and lower extremity weakness. Most forms of this condition are associated with a mutation in a gene on chromosome 9, at band q13, which codes for the mitochondrial protein frataxin. (From Adams et al., Principles of Neurology, 6th ed, p1081; N Engl J Med 1996 Oct 17;335(16):1169-75) The severity of Friedreich ataxia associated with expansion of GAA repeats in the first intron of the frataxin gene correlates with the number of trinucleotide repeats. (From Durr et al, N Engl J Med 1996 Oct 17;335(16):1169-75)Spinocerebellar Ataxias: A group of dominantly inherited, predominately late-onset, cerebellar ataxias which have been divided into multiple subtypes based on clinical features and genetic mapping. Progressive ataxia is a central feature of these conditions, and in certain subtypes POLYNEUROPATHY; DYSARTHRIA; visual loss; and other disorders may develop. (From Joynt, Clinical Neurology, 1997, Ch65, pp 12-17; J Neuropathol Exp Neurol 1998 Jun;57(6):531-43)Gait Ataxia: Impairment of the ability to coordinate the movements required for normal ambulation (WALKING) which may result from impairments of motor function or sensory feedback.

Affected individuals are prone to recurrent sinobronchopulmonary infections, lymphoreticular neoplasms, and other malignancies. Serum ALPHA-FETOPROTEINS are usually elevated. (Menkes, Textbook of Child Neurology, 5th ed, p688) The gene for this disorder (ATM) encodes a cell cycle checkpoint protein kinase and has been mapped to chromosome 11 (11q22-q23).Ataxia Telangiectasia Mutated Proteins: A group of PROTEIN-SERINE-THREONINE KINASES which activate critical signaling cascades in double strand breaks, APOPTOSIS, and GENOTOXIC STRESS such as ionizing ultraviolet A light, thereby acting as a DNA damage sensor. These proteins play a role in a wide range of signaling mechanisms in cell cycle control.Iron-Binding Proteins: Proteins that specifically bind to IRON.Machado-Joseph Disease: A dominantly-inherited ATAXIA first described in people of Azorean and Portuguese descent, and subsequently identified in Brazil, Japan, China, and Australia. This disorder is classified as one of the SPINOCEREBELLAR ATAXIAS (Type 3) and has been associated with a mutation of the MJD1 gene on chromosome 14. Clinical features include progressive ataxia, DYSARTHRIA, postural instability, nystagmus, eyelid retraction, and facial FASCICULATIONS. DYSTONIA is prominent in younger patients (referred to as Type I Machado-Joseph Disease). Type II features ataxia and ocular signs; Type III features MUSCULAR ATROPHY and a sensorimotor neuropathy; and Type IV features extrapyramidal signs combined with a sensorimotor neuropathy. (From Clin Neurosci 1995;3(1):17-22; Ann Neurol 1998 Mar;43(3):288-96)Trinucleotide Repeat Expansion: An increased number of contiguous trinucleotide repeats in the DNA sequence from one generation to the next. The presence of these regions is associated with diseases such as FRAGILE X SYNDROME and MYOTONIC DYSTROPHY. Some CHROMOSOME FRAGILE SITES are composed of sequences where trinucleotide repeat expansion occurs.Trinucleotide Repeats: Microsatellite repeats consisting of three nucleotides dispersed in the euchromatic arms of chromosomes.Cerebellum: The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.Tumor Suppressor Proteins: Proteins that are normally involved in holding cellular growth in check. Deficiencies or abnormalities in these proteins may lead to unregulated cell growth and tumor development.Cell Cycle Proteins: Proteins that control the CELL DIVISION CYCLE. This family of proteins includes a wide variety of classes, including CYCLIN-DEPENDENT KINASES, mitogen-activated kinases, CYCLINS, and PHOSPHOPROTEIN PHOSPHATASES as well as their putative substrates such as chromatin-associated proteins, CYTOSKELETAL PROTEINS, and TRANSCRIPTION FACTORS.Purkinje Cells: The output neurons of the cerebellar cortex.Pedigree: The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.Protein-Serine-Threonine Kinases: A group of enzymes that catalyzes the phosphorylation of serine or threonine residues in proteins, with ATP or other nucleotides as phosphate donors.Cerebellar Diseases: Diseases that affect the structure or function of the cerebellum. Cardinal manifestations of cerebellar dysfunction include dysmetria, GAIT ATAXIA, and MUSCLE HYPOTONIA.Mutation: Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.Ocular Motility Disorders: Disorders that feature impairment of eye movements as a primary manifestation of disease. These conditions may be divided into infranuclear, nuclear, and supranuclear disorders. Diseases of the eye muscles or oculomotor cranial nerves (III, IV, and VI) are considered infranuclear. Nuclear disorders are caused by disease of the oculomotor, trochlear, or abducens nuclei in the BRAIN STEM. Supranuclear disorders are produced by dysfunction of higher order sensory and motor systems that control eye movements, including neural networks in the CEREBRAL CORTEX; BASAL GANGLIA; CEREBELLUM; and BRAIN STEM. Ocular torticollis refers to a head tilt that is caused by an ocular misalignment. Opsoclonus refers to rapid, conjugate oscillations of the eyes in multiple directions, which may occur as a parainfectious or paraneoplastic condition (e.g., OPSOCLONUS-MYOCLONUS SYNDROME). (Adams et al., Principles of Neurology, 6th ed, p240)Nerve Tissue ProteinsFragile X Syndrome: A condition characterized genotypically by mutation of the distal end of the long arm of the X chromosome (at gene loci FRAXA or FRAXE) and phenotypically by cognitive impairment, hyperactivity, SEIZURES, language delay, and enlargement of the ears, head, and testes. INTELLECTUAL DISABILITY occurs in nearly all males and roughly 50% of females with the full mutation of FRAXA. (From Menkes, Textbook of Child Neurology, 5th ed, p226)Apraxias: A group of cognitive disorders characterized by the inability to perform previously learned skills that cannot be attributed to deficits of motor or sensory function. The two major subtypes of this condition are ideomotor (see APRAXIA, IDEOMOTOR) and ideational apraxia, which refers to loss of the ability to mentally formulate the processes involved with performing an action. For example, dressing apraxia may result from an inability to mentally formulate the act of placing clothes on the body. Apraxias are generally associated with lesions of the dominant PARIETAL LOBE and supramarginal gyrus. (From Adams et al., Principles of Neurology, 6th ed, pp56-7)Age of Onset: The age, developmental stage, or period of life at which a disease or the initial symptoms or manifestations of a disease appear in an individual.Dysarthria: Disorders of speech articulation caused by imperfect coordination of pharynx, larynx, tongue, or face muscles. This may result from CRANIAL NERVE DISEASES; NEUROMUSCULAR DISEASES; CEREBELLAR DISEASES; BASAL GANGLIA DISEASES; BRAIN STEM diseases; or diseases of the corticobulbar tracts (see PYRAMIDAL TRACTS). The cortical language centers are intact in this condition. (From Adams et al., Principles of Neurology, 6th ed, p489)DNA-Binding Proteins: Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.Fragile X Mental Retardation Protein: A RNA-binding protein that is found predominately in the CYTOPLASM. It helps regulate GENETIC TRANSLATION in NEURONS and is absent or under-expressed in FRAGILE X SYNDROME.Genes, Recessive: Genes that influence the PHENOTYPE only in the homozygous state.Syndrome: A characteristic symptom complex.DNA Damage: Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS.Myoclonic Cerebellar Dyssynergia: A condition marked by progressive CEREBELLAR ATAXIA combined with MYOCLONUS usually presenting in the third decade of life or later. Additional clinical features may include generalized and focal SEIZURES, spasticity, and DYSKINESIAS. Autosomal recessive and autosomal dominant patterns of inheritance have been reported. Pathologically, the dentate nucleus and brachium conjunctivum of the CEREBELLUM are atrophic, with variable involvement of the spinal cord, cerebellar cortex, and basal ganglia. (From Joynt, Clinical Neurology, 1991, Ch37, pp60-1)Nystagmus, Pathologic: Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life. (Adams et al., Principles of Neurology, 6th ed, p272)DNA Repeat Expansion: An increase number of repeats of a genomic, tandemly repeated DNA sequence from one generation to the next.Kv1.1 Potassium Channel: A delayed rectifier subtype of shaker potassium channels that is commonly mutated in human episodic ATAXIA and MYOKYMIA.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images.

Some are VIRAL INCLUSION BODIES.Olivopontocerebellar Atrophies: A group of inherited and sporadic disorders which share progressive ataxia in combination with atrophy of the CEREBELLUM; PONS; and inferior olivary nuclei. Additional clinical features may include MUSCLE RIGIDITY; NYSTAGMUS, PATHOLOGIC; RETINAL DEGENERATION; MUSCLE SPASTICITY; DEMENTIA; URINARY INCONTINENCE; and OPHTHALMOPLEGIA. The familial form has an earlier onset (second decade) and may feature spinal cord atrophy. The sporadic form tends to present in the fifth or sixth decade, and is considered a clinical subtype of MULTIPLE SYSTEM ATROPHY. (From Adams et al., Principles of Neurology, 6th ed, p1085)Genes, Dominant: Genes that influence the PHENOTYPE both in the homozygous and the heterozygous state.Heredodegenerative Disorders, Nervous System: Inherited disorders characterized by progressive atrophy and dysfunction of anatomically or physiologically related neurologic systems.Mutation, Missense: A mutation in which a codon is mutated to one directing the incorporation of a different amino acid. This substitution may result in an inactive or unstable product. (From A Dictionary of Genetics, King & Stansfield, 5th ed)Multiple System Atrophy: A syndrome complex composed of three conditions which represent clinical variants of the same disease process: STRIATONIGRAL DEGENERATION; SHY-DRAGER SYNDROME; and the sporadic form of OLIVOPONTOCEREBELLAR ATROPHIES. Clinical features include autonomic, cerebellar, and basal ganglia dysfunction. Pathologic examination reveals atrophy of the basal ganglia, cerebellum, pons, and medulla, with prominent loss of autonomic neurons in the brain stem and spinal cord. (From Adams et al., Principles of Neurology, 6th ed, p1076; Baillieres Clin Neurol 1997 Apr;6(1):187-204; Med Clin North Am 1999 Mar;83(2):381-92)Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM).

The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Gliadin: Simple protein, one of the prolamines, derived from the gluten of wheat, rye, etc. May be separated into 4 discrete electrophoretic fractions. It is the toxic factor associated with CELIAC DISEASE.Vitamin E Deficiency: A nutritional condition produced by a deficiency of VITAMIN E in the diet, characterized by posterior column and spinocerebellar tract abnormalities, areflexia, ophthalmoplegia, and disturbances of gait, proprioception, and vibration. In premature infants vitamin E deficiency is associated with hemolytic anemia, thrombocytosis, edema, intraventricular hemorrhage, and increasing risk of retrolental fibroplasia and bronchopulmonary dysplasia. An apparent inborn error of vitamin E metabolism, named familial isolated vitamin E deficiency, has recently been identified. (Cecil Textbook of Medicine, 19th ed, p1181)Neurologic Examination: Assessment of sensory and motor responses and reflexes that is used to determine impairment of the nervous system.Calcium Channels, Q-Type: CALCIUM CHANNELS located in the neurons of the brain.Homozygote: An individual in which both alleles at a given locus are identical.Myoclonus: Involuntary shock-like contractions, irregular in rhythm and amplitude, followed by relaxation, of a muscle or a group of muscles.

These disorders are often associated with atrophy of the affected central or peripheral nervous system structures.Atrophy: Decrease in the size of a cell, tissue, organ, or multiple organs, associated with a variety of pathological conditions such as abnormal cellular changes, ischemia, malnutrition, or hormonal changes.DNA Repair: The reconstruction of a continuous two-stranded DNA molecule without mismatch from a molecule which contained damaged regions. The major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. Excision repair and post-replication repair are sometimes referred to as "dark repair" because they do not require light.Nervous System Diseases: Diseases of the central and peripheral nervous system. This includes disorders of the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, autonomic nervous system, neuromuscular junction, and muscle.Checkpoint Kinase 2: Enzyme activated in response to DNA DAMAGE involved in cell cycle arrest.

The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.Fasciculation: Involuntary contraction of the muscle fibers innervated by a motor unit. Fasciculations can often by visualized and take the form of a muscle twitch or dimpling under the skin, but usually do not generate sufficient force to move a limb. They may represent a benign condition or occur as a manifestation of MOTOR NEURON DISEASE or PERIPHERAL NERVOUS SYSTEM DISEASES. (Adams et al., Principles of Neurology, 6th ed, p1294)Miller Fisher Syndrome: A variant of the GUILLAIN-BARRE SYNDROME characterized by the acute onset of oculomotor dysfunction, ataxia, and loss of deep tendon reflexes with relative sparing of strength in the extremities and trunk. The ataxia is produced by peripheral sensory nerve dysfunction and not by cerebellar injury. Facial weakness and sensory loss may also occur. The process is mediated by autoantibodies directed against a component of myelin found in peripheral nerves. (Adams et al., Principles of Neurology, 6th ed, p1313; Neurology 1987 Sep;37(9):1493-8)Heterozygote: An individual having different alleles at one or more loci regarding a specific character.Myoclonic Epilepsies, Progressive: A heterogeneous group of primarily familial disorders characterized by myoclonic seizures, tonic-clonic seizures, ataxia, progressive intellectual deterioration, and neuronal degeneration.

Myoclonic epilepsy syndromes are divided into three subtypes based on etiology: familial, cryptogenic, and symptomatic (i.e., occurring secondary to known disease processes such as infections, hypoxic-ischemic injuries, trauma, etc.).Intellectual Disability: Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range. (from Joynt, Clinical Neurology, 1992, Ch55, p28)Ophthalmoplegia: Paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.Optic Atrophy: Atrophy of the optic disk which may be congenital or acquired. This condition indicates a deficiency in the number of nerve fibers which arise in the RETINA and converge to form the OPTIC DISK; OPTIC NERVE; OPTIC CHIASM; and optic tracts. GLAUCOMA; ISCHEMIA; inflammation, a chronic elevation of intracranial pressure, toxins, optic nerve compression, and inherited conditions (see OPTIC ATROPHIES, HEREDITARY) are relatively common causes of this condition.Hypoalbuminemia: A condition in which albumin level in blood (SERUM ALBUMIN) is below the normal range. Hypoalbuminemia may be due to decreased hepatic albumin synthesis, increased albumin catabolism, altered albumin distribution, or albumin loss through the urine (ALBUMINURIA).Phosphotransferases (Alcohol Group Acceptor): A group of enzymes that transfers a phosphate group onto an alcohol group acceptor. EC 2.7.1.Disease Models, Animal: Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases.

Proprioception provides sense of stationary positions and movements of one's body parts, and is important in maintaining KINESTHESIA and POSTURAL BALANCE.Pyramidal Tracts: Fibers that arise from cells within the cerebral cortex, pass through the medullary pyramid, and descend in the spinal cord. Many authorities say the pyramidal tracts include both the corticospinal and corticobulbar tracts.Visual Pathways: Set of cell bodies and nerve fibers conducting impulses from the eyes to the cerebral cortex. It includes the RETINA; OPTIC NERVE; optic tract; and geniculocalcarine tract.Movement: The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.Motor Cortex: Area of the FRONTAL LOBE concerned with primary motor control located in the dorsal PRECENTRAL GYRUS immediately anterior to the central sulcus. It is comprised of three areas: the primary motor cortex located on the anterior paracentral lobule on the medial surface of the brain; the premotor cortex located anterior to the primary motor cortex; and the supplementary motor area located on the midline surface of the hemisphere anterior to the primary motor cortex.Spinocerebellar Degenerations: A heterogenous group of degenerative syndromes marked by progressive cerebellar dysfunction either in isolation or combined with other neurologic manifestations.

It should be distinguished from sympathy, which is usually nonobjective and noncritical. It includes caring, which is the demonstration of an awareness of and a concern for the good of others. (From Bioethics Thesaurus, 1992)Cerebral Palsy: A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)Drug Discovery: The process of finding chemicals for potential therapeutic use.Walking: An activity in which the body advances at a slow to moderate pace by moving the feet in a coordinated fashion.

Ataxia, ocular telangiectasia, chromosome instability, and Langerhans cell histiocytosis in a patient with an unknown breakage syndrome. (1/764)

An 8 year old boy who had Langerhans cell histiocytosis when he was 15 months old showed psychomotor regression from the age of 2 years. Microcephaly, severe growth deficiency, and ocular telangiectasia were also evident. Magnetic nuclear resonance imaging showed cerebellar atrophy. Alphafetoprotein was increased. Chromosome instability after x irradiation and rearrangements involving chromosome 7 were found. Molecular study failed to show mutations involving the ataxia-telangiectasia gene. This patient has a clinical picture which is difficult to relate to a known breakage syndrome. Also, the relationship between the clinical phenotype and histiocytosis is unclear.  (+info)

Biological activity of netilmicin, a broad-spectrum semisynthetic aminoglycoside antibiotic. (2/764)

Netilmicin (Sch 20569) is a new broad-spectrum semisynthetic aminoglycoside derived from sisomicin. Netilmicin was compared to gentamicin, tobramycin, and amikacin in a variety of in vitro test systems as well as in mouse protection tests. Netilmicin was found to be similar in activity to gentamicin against aminoglycoside-susceptible strains in both in vitro and in vivo tests. Netilmicin was also active against many aminoglycoside-resistant strains of gram-negative bacteria, particularly those known to possess adenylating enzymes (ANT 2') or those with a similar resistance pattern. Netilmicin was found to be markedly less toxic than gentamicin in chronic studies in cats, although gentamicin appeared less toxic in acute toxicity tests in mice. The concentrations of netilmicin and gentamicin in serum were compared in dogs after intramuscular dosing, and the pharmacokinetics including peak concentrations in serum were found to be similar.  (+info)

Targeted disruption of the murine Nhe1 locus induces ataxia, growth retardation, and seizures. (3/764)

In most cells, the ubiquitously expressed Na+/H+ exchanger isoform 1 (NHE1) is thought to be a primary regulator of pH homeostasis, cell volume regulation, and the proliferative response to growth factor stimulation. To study the function of NHE1 during embryogenesis when these cellular processes are very active, we targeted the Nhe1 gene by replacing the sequence encoding transmembrane domains 6 and 7 with the neomycin resistance gene. NHE activity assays on isolated acinar cells indicated that the targeted allele is functionally null. Although the absence of NHE1 is compatible with embryogenesis, Nhe1 homozygous mutants (-/-) exhibit a decreased rate of postnatal growth that is first evident at 2 wk of age. At this time, Nhe1 -/- animals also begin to exhibit ataxia and epileptic-like seizures. Approximately 67% of the -/- mutants die before weaning. Postmortem examinations frequently revealed an accumulation of a waxy particulate material inside the ears, around the eyes and chin, and on the ventral surface of the paws. Histological analysis of adult tissues revealed a thickening of the lamina propria and a slightly atrophic glandular mucosa in the stomach.  (+info)

Anticonvulsant efficacy of N-methyl-D-aspartate antagonists against convulsions induced by cocaine. (4/764)

Convulsions associated with cocaine abuse can be life threatening and resistant to standard emergency treatment. Cocaine (75 mg/kg, i. p.) produced clonic convulsions in approximately 90% of male, Swiss-Webster mice. A variety of clinically used antiepileptic agents did not significantly protect against cocaine convulsions (e. g., diazepam and phenobarbital). Anticonvulsants in clinical practice that did significantly protect against convulsion did so only at doses with significant sedative/ataxic effects (e.g., clonazepam and valproic acid). In contrast, functional N-methyl-D-aspartate (NMDA) antagonists all produced dose-dependent and significant protection against the convulsant effects of cocaine. Anticonvulsant efficacy was achieved by blockade of both competitive and noncompetitive modulatory sites on the NMDA receptor complex. Thus, competitive antagonists, ion-channel blockers, polyamine antagonists, and functional blockers of the strychnine-insensitive glycine modulatory site all prevented cocaine seizures. The role of NMDA receptors in the control of cocaine-induced convulsions was further strengthened by the positive correlation between the potencies of noncompetititve antagonists or competitive antagonists to block convulsions and their respective affinities for their specific binding sites on the NMDA receptor complex. Although some NMDA blockers produced profound behavioral side effects at efficacious doses (e.g., noncompetitive antagonists), others (e.g., some low-affinity channel blockers, some competitive antagonists, and glycine antagonists) demonstrated significant and favorable separation between their anticonvulsant and side effect profiles. The present results provide the most extensive evidence to date identifying NMDA receptor blockade as a potential strategy for the discovery of agents for clinical use in averting toxic sequelae from cocaine overdose. Given the literature suggesting a role for these drugs in other areas of drug abuse treatments, NMDA receptor antagonists sit in a unique position as potential therapeutic candidates.  (+info)

Neurotoxicity and behavioral effects of thiram in rats. (5/764)

Eight of 24 female rats fed 66.9 mg/kg-day of thiram developed neurotoxicity. The neurotoxic effects were characterized by ataxia and paralysis of the hind legs. There were demyelination, degeneration of the axis cylinders, and presence of macrophages in the nerve bundle of the sciatic nerve. Degeneration in the ventral horn of the lower lumbar region of the spinal cord was evidenced by chromatolysis of motorneurons, pyknosis, and satellitosis. During a second experiment, 4 of 24 females fed 65.8 mg/kg--day also developed ataxia and paralysis. An additional 9 females showed clasping of the hind feet when picked up by the tail. Nerve conduction could not be measured for one severely ataxic rat and the electromyogram indicated a loss of motor unit function. Histopathology of this rat, along with the others, suggests the peripheral nerve as the primary site of the lesion. Thiram also caused behavioral changes in apparently normal rats. The walking pattern of the hind legs was altered with decreases in stride width and the angle between contralateral steps. These rats required significantly more shock-motivations and cleared a lower height in a jump/climb ability test. An open-field study indicated that thiram caused hyperactivity in the nonataxic rats of both sexes. Three of 24 rats fed 95.8 mg/kg-day of ferbam also developed ataxia or paralysis.  (+info)

A lysosomal storage disease induced by Ipomoea carnea in goats in Mozambique. (6/764)

A novel plant-induced lysosomal storage disease was observed in goats from a village in Mozambique. Affected animals were ataxic, with head tremors and nystagmus. Because of a lack of suitable feed, the animals consumed an exotic hedge plant growing in the village that was identified as Ipomoea carnea (shrubby morning glory, Convolvulaceae). The toxicosis was reproduced by feeding I. carnea plant material to goats. In acute cases, histologic changes in the brain and spinal cord comprised widespread cytoplasmic vacuolation of neurons and glial cells in association with axonal spheroid formation. Ultrastructurally, cytoplasmic storage vacuoles in neurons were membrane bound and consistent with lysosomes. Cytoplasmic vacuolation was also found in neurons in the submucosal and mesenteric plexuses in the small intestine, in renal tubular epithelial cells, and in macrophage-phagocytic cells in the spleen and lymph nodes in acute cases. Residual alterations in the brain in chronic cases revealed predominantly cerebellar lesions characterized by loss of Purkinje neurons and gliosis of the Purkinje cell layer. Analysis of I. carnea plant material by gas chromatography-mass spectrometry established the presence of the mannosidase inhibitor swainsonine and 2 glycosidase inhibitors, calystegine B2 and calystegine C1, consistent with a plant-induced alpha-mannosidosis in the goats. The described storage disorder is analogous to the lysosomal storage diseases induced by ingestion of locoweeds (Astragalus and Oxytropis) and poison peas (Swainsona).  (+info)

A novel mutation in the human voltage-gated potassium channel gene (Kv1.1) associates with episodic ataxia type 1 and sometimes with partial epilepsy. (7/764)

Episodic ataxia type 1 (EA1) is a rare autosomal dominant disorder characterized by brief episodes of ataxia associated with continuous interattack myokymia. Point mutations in the human voltage-gated potassium channel (Kv1.1) gene on chromosome 12p13 have recently been shown to associate with EA1. A Scottish family with EA1 harbouring a novel mutation in this gene is reported. Of the five affected individuals over three generations, two had partial epilepsy in addition to EA1. The detailed clinical, electrophysiological and molecular genetic findings are presented. The heterozygous point mutation is located at nucleotide position 677 and results in a radical amino acid substitution at a highly conserved position in the second transmembrane domain of the potassium channel. Functional studies indicated that mutant subunits exhibited a dominant negative effect on potassium channel function and would be predicted to impair neuronal repolarization. Potassium channels determine the excitability of neurons and blocking drugs are proconvulsant. A critical review of previously reported EA1 families shows an over-representation of epilepsy in family members with EA1 compared with unaffected members. These observations indicate that this mutation is pathogenic and suggest that the epilepsy in EA1 may be caused by the dysfunctional potassium channel. It is possible that such dysfunction may be relevant to other epilepsies in man.  (+info)

Neurotoxic effects of 2,5-hexanedione on normal and neurofilament-deficient quail. (8/764)

The neurotoxic effects of 2,5-hexanedione (2,5-HD) were investigated using neurofilament (NF)-deficient (Quv) Japanese quail in comparison with normal Japanese quail. Both Quv and normal Japanese quail were inoculated intraperitoneally with 350 mg/kg/day 2,5-HD for 6 consecutive wk. The results of 2,5-HD exposure differed substantially between the 2 strains of Japanese quail. The 2,5-HD-exposed normal quail showed leg paralysis about 4 wk after initiation of dosing. Some treated normal quail fell into dysstasia and died of nutritional disturbances. Histologically, 2,5-HD-treated normal quail had NF-rich axonal swellings and degeneration in the distal parts of the peripheral nerves, spinal cord, and cerebellar peduncles. In contrast, 2,5-HD-injected Quv quail showed tonic convulsion, ataxia gait, severe quivering, and excitation about 2-3 days after administration. Some treated Quv birds died immediately after systemic tonic convulsion, probably because of asphyxia. Although all treated Quv quail showed neurologic signs, there were no recognizable 2,5-HD-induced lesions in the nervous system. After about 4-6 wk of dosing, 2,5-HD induced distal axonopathy in normal quail and acute neurotoxicity in Quv quail.  (+info)

Penetrance of the Fragile X-Associated Tremor/Ataxia Syndrome in a Premutation Carrier Population  Penetrance of the Fragile X-Associated Tremor/Ataxia Syndrome in a Premutation Carrier Population
Premutation expansions (55-200 CGG repeats) of the fragile X mental retardation 1 (FMR1) gene are frequent in the general population, with estimated prevalences of 1 per 259 females and 1 per 813 males. Several articles have recently described the presence of late-onset neurological symptoms in male carriers of premutation (FMR1) alleles. The main clinical features described in this newly identified syndrome are cerebellar ataxia and intention tremor. Additional documented symptoms include short-term memory loss, executive functional deficits, cognitive decline, parkinsonism, peripheral neuropathy, lower-limb proximal muscle weakness, and autonomic dysfunction.To study the penetrance of the fragile X-associated tremor/ataxia syndrome (FXTAS) among premutation carriers.Family-based study of 192 individuals (premutation carriers and controls) whose families belong to the Northern or Southern California Fragile X Associations.

N2 - The human FMR1 gene contains an unstable CGG-repeat in its 5′ untranslated region. The repeat length in the normal population is polymorphic (5-54 CGG-repeats). Individuals carrying lengths beyond 200 CGGs (i.e. the full mutation) show hypermethylation and as a consequence gene silencing of the FMR1 gene. The absence of the gene product FMRP causes the fragile X syndrome, the most common inherited form of mental retardation. Elderly carriers of the premutation (PM), which is defined as a repeat length between 55 and 200 CGGs, can develop a progressive neurodegenerative syndrome: fragile X-associated tremor/ataxia syndrome (FXTAS).

Cerebral Ataxia, also known as Cerebellar Ataxia or Cerebellar Ataxia Syndrome, is similar to Ataxic Cerebral Palsy in some ways but different in others. They are both marked by the same symptoms such as an unsteady walk, poor muscle tone, and lack of coordination.. Unlike Ataxic CP, Cerebral Ataxia doesnt necessarily occur in birth. It can also be classified as acute, where the disorder appears suddenly and in high severity, or chronic, wherein the disorder progresses over a stretched out period of time. Cerebral Ataxia can even be recurrent and happen on and off over short or long periods of time. There are even cases where it develops at a late age but the patient can still live for years afterwards.. Also like Ataxic Cerebral Palsy, Cerebral Ataxia has many different causes. They can include infectious diseases, genetic conditions, tumors, trauma, and vascular conditions. Because many of these conditions can happen at any point in someones life, it is possible to develop Cerebral Ataxia at ...

Differential increases of specific FMR1 mRNA isoforms in premutation carriers | Journal of Medical Genetics  Differential increases of specific FMR1 mRNA isoforms in premutation carriers | Journal of Medical Genetics
Background Over 40% of male and ∼16% of female carriers of a premutation FMR1 allele (55-200 CGG repeats) will develop fragile X-associated tremor/ataxia syndrome, an adult onset neurodegenerative disorder, while about 20% of female carriers will develop fragile X-associated primary ovarian insufficiency. Marked elevation in FMR1 mRNA transcript levels has been observed with premutation alleles, and RNA toxicity due to increased mRNA levels is the leading molecular mechanism proposed for these disorders. However, although the FMR1 gene undergoes alternative splicing, it is unknown whether all or only some of the isoforms are overexpressed in premutation carriers and which isoforms may contribute to the premutation pathology.. ...

4-Aminopyridine in Episodic Ataxia Type 2 - Full Text View - ClinicalTrials.gov  4-Aminopyridine in Episodic Ataxia Type 2 - Full Text View - ClinicalTrials.gov
This study aims to determine whether 4-aminopyridine (4AP) can reduce attacks of ataxia in patients with episodic ataxia type 2 (EA2), a rare but often debilitating condition. Episodic ataxia (EA) is a group of inherited disorders characterized by recurrent, discrete episodes of vertigo and ataxia variably associated with progressive ataxia. EA2, the most common and the best characterized of all the EA syndromes, is caused by heterozygous mutations in CACNA1A, which encodes the main subunit of a neuronal voltage-gated calcium channel, Cav2.1.. Although observational data suggest symptomatic resolution with acetazolamide in many EA2 patients, the investigators found in our patient databases that at least a third of the EA2 patients continue to suffer debilitating ataxia attacks, either because of incomplete control while on acetazolamide or because of intolerability or hypersensitivity to acetazolamide. For these patients there is no alternative intervention. 4-Aminopyridine (4AP) has been found ...

The posterior parietal cortex (PPC) is thought to play an important role in the sensorimotor transformations associated with reaching movements. In humans, damage to the PPC, particularly bilateral lesions, leads to impairments of visually guided reaching movements (optic ataxia). Recent accounts of optic ataxia based upon electrophysiological recordings in monkeys have proposed that this disorder arises because of a breakdown in the tuning fields of parietal neurons responsible for integrating spatially congruent retinal, eye, and hand position signals to produce coordinated eye and hand movements . We present neurological evidence that forces a reconceptualization of this view. We report a detailed case study of a patient with a limb-dependent form of optic ataxia who can accurately reach with either hand to objects that he can foveate (thereby demonstrating coordinated eye-hand movements) but who cannot effectively decouple reach direction from gaze direction for movements executed using his right

Episodic ataxia type 2 (EA2) is characterized by paroxysmal attacks of ataxia, vertigo, and nausea typically lasting minutes to days in duration. Attacks can be associated with dysarthria, diplopia, tinnitus, dystonia, hemiplegia, and headache. About 50% of individuals with EA2 have migraine headaches. Onset is typically in childhood or early adolescence (age range 2-32 years). Frequency of attacks can range from once or twice a year to three or four times a week. Attacks can be triggered by stress, exertion, caffeine, alcohol, fever, heat, and phenytoin; they can be stopped or decreased in frequency and severity by administration of acetazolamide or 4-aminopyridine. Between attacks, individuals may initially be asymptomatic but commonly develop interictal findings that can include nystagmus, pursuit and saccade alterations, and ataxia.

Attacks of ataxia, or the loss of ability to coordinate muscular movement, are often triggered by stress or exertion. EA is likely caused by an inherited genetic mutation; many individuals with EA have abnormalities in the KCNA1 or CACNA1A genes. To date, two known subtypes of EA have been identified, and other types likely exist. Specific characteristics of each EA subtype, however, have not been adequately described. The purpose of this study is to better define the clinical features and genetic basis of the various subtypes of EA and to evaluate disease progression. The study will also establish relevant study endpoints for use in future therapeutic trials.. This multi-center observational study will involve both a cross-sectional data analysis and a prospective longitudinal analysis. Participants will initially attend an outpatient study visit that will last 7 hours. This initial evaluation will include a medical history, a physical examination, neurological testing, and an ataxia ...

Ataxia What is ataxia? The word ataxia comes from the Greek word a taxis, which means without order or without coordination. Thus, ataxia means without coordination. Persons who are diagnosed with ataxia experience a failure of muscle control in their arms and legs which may result in a lack of balance, coordination, and possibly a disturbance in gait. Ataxia may affect the fingers, hands, arms, legs, body, speech, and even eye movements. The word ataxia is often used to describe the incoordinatio...

Broadly speaking, the word ataxia simply means unsteadiness and clumsiness, and has been given to the condition because those are usually the earliest symptoms. As the disorder progresses, people with ataxia usually lose the ability to walk, and can become totally disabled, having to depend on others for their care. This is because ataxia destroys both nerve and muscle cells. Vision (and in some cases hearing) and speech may also be affected.

Murine hippocampal neurons expressing Fmr1 gene premutations show early developmental deficits and late degeneration  Murine hippocampal neurons expressing Fmr1 gene premutations show early developmental deficits and late degeneration
Premutation CGG repeat expansions (55-200 CGG repeats; preCGG) within the fragile X mental retardation 1 (FMR1) gene give rise to the neurodegenerative disorder, fragile X-associated tremor/ataxia syndrome (FXTAS), primary ovarian insufficiency and neurodevelopmental problems. Morphometric analysis of Map2B immunofluorescence reveals that neurons cultured from heterozygous female mice with preCGG repeats in defined medium display shorter dendritic lengths and fewer branches between 7 and 21 days in vitro compared with wild-type (WT) littermates. Although the numbers of synapsin and phalloidin puncta do not differ from WT, preCGG neurons possess larger puncta. PreCGG neurons display lower viability, and express elevated stress protein as they mature. PreCGG neurons have inherently different patterns of growth, dendritic complexity and synaptic architecture discernable early in the neuronal trajectory to maturation, and may reflect a cellular basis for the developmental component of the spectrum ...

The cerebellum and its major connection are subject to a number of diseases. One of the most relevant consequences of cerebellar dysfunction is ataxia, a neurological dysfunction of motor coordination, which may affect fundamental activities such as gaze, speech, gait, and balance1. The hereditary ataxias comprise a very large spectrum of genetically determined neurodegenerative disorders with progressive ataxia as the prominent symptom2. The International Cooperative Ataxia Rating Scale (ICARS) is a scale developed to assess cerebellar ataxia3. ICARS was found to be a reliable scale satisfying accepted criteria for interrater reliability, test_retest reliability, and internal consistency. Although validity testing was limited, It was found evidence of validity of ICARS when ataxia disease stages and Barthel index were used as external criteria4,5.. In order to measure the severity of cerebellar ataxia in an easier and more practical way, Schmitz-Hubsch et al proposed a new scale: the Scale for ...

Author Summary Hereditary ataxias are a heterogeneous group of rare disorders characterized by progressive cerebellar neurodegeneration. Several causative mutations have been identified in various forms of human ataxias. In addition to humans, inherited ataxias have been described in several other species, including the domestic dog. In this study, we have studied the clinical and genetic properties of cerebellar ataxia in the Finnish Hound dog breed. The breed suffers from a progressive ataxia that has an early onset before the age of 3 months. Affected puppies have difficulties in coordinating their movements and balance, and have to be euthanized due to rapidly worsening symptoms. Our pedigree analysis suggested an autosomal recessive mode of inheritance, which was confirmed by identifying a homozygous mutation in the SEL1L gene through genome-wide association and linkage analyses. The SEL1L protein functions in a protein quality control pathway that targets misfolded proteins to degradation in the

Twenty-six percent had chickenpox, 52% had other illnesses that were presumed to be viral, and in 3% the ataxia was related to immunization. Nineteen percent had no definite prodrome. Sixty children were followed for 4 months or longer after onset of their ataxia (mean, 7.4 f 6.0 years). Ninety-one percent (55160)of these, including all children with chickenpox, recovered completely from ataxia. Eighty-nine percent (39/44)of the children with non-varicellarelated ataxia recovered completely from the ataxia, a much better rate of recovery than what was found in prior large studies.

Ataxia in Dogs  Ataxia in Dogs
The word "ataxia" comes from two roots: a meaning "lack" and taxia meaning "order." So literally, the staggering we see is a "lack of order," or incoordination, within the nervous system. The abnormal movement can occur in the legs, the head, the torso, or all three.. There are several different forms of ataxia, depending on where in the nervous system the abnormality occurs. The first is a failure of the unconscious awareness of where the body - specifically the limbs - are located in space. This unconscious body awareness is called "proprioception," and when there is a proprioceptive abnormality, movement is difficult and quite abnormal. A proprioceptive defect most commonly occurs in the wake of pressure on the spinal cord from a bulging intervertebral disk or tumor, from a tumor within the spinal cord itself, from a bleeding blood vessel within the spinal cord, or a failure of the nerve conduction capacity of the spinal cord.. ...

The Fragile X Factor : Emory Magazine  The Fragile X Factor : Emory Magazine
The National Institutes of Health (NIH) has awarded a five-year grant of more than $9 million to Emory researchers to study fragile X syndrome-associated disorders and work toward developing effective treatments.. The grant is one of three nationally to support the Centers for Collaborative Research in Fragile X, and a renewal of Emorys National Fragile X Syndrome Research Center that has been continuously funded by NIH since the inception of such centers ten years ago.. Fragile X syndrome is the most common form of inherited intellectual and developmental disabilities and often results in emotional and behavioral problems; as many as 30 to 50 percent of people with fragile X syndrome also have features of autism spectrum disorders.. Fragile X syndrome, fragile X-associated tremor/ataxia syndrome (FXTAS), and fragile X-associated primary ovarian insufficiency (FXPOI) result from a variety of mutations in the FMR1 gene.. FMR1 normally makes a protein that helps create and maintain connections ...

The main risk factor for FXS is having a parent with an FMR1 mutation. Most people who inherit a minor mutation, which is sometimes called a premutation, do not develop the symptoms and signs of FXS. A few premutated children may show signs that resemble autism. Others, primarily males, may develop a set of neurological symptoms called fragile X tremor ataxia syndrome in later adult life. Females may develop FMR1-related premature ovarian insufficiency.. Children of mothers with FMR1 premutations are at risk of inheriting a fully mutated FMR1 gene severe enough to cause symptomatic FXS. If a woman does not have symptoms and is a carrier of an FMR1 mutation or premutation, each child of hers has a 50% chance of inheriting that gene. Of the children that inherit that gene, boys are much more likely to develop symptoms than girls. The severity of the disorder may vary between different individuals in the same family.. In general, each generation tends to have worse mutations and a higher risk of ...

Aberrant cerebellar Purkinje cell activity as the cause of motor attacks in a mouse model of episodic ataxia type 2 | Disease...  Aberrant cerebellar Purkinje cell activity as the cause of motor attacks in a mouse model of episodic ataxia type 2 | Disease...
The data presented here support the hypothesis that highly erratic activity of Purkinje cells during caffeine-induced attacks is the cause of motor abnormalities in tottering mice. This is in agreement with earlier studies that have shown that Purkinje cells are sufficient, and required, for the initiation of attacks in this mouse model (Campbell et al., 1999; Mark et al., 2011; Raike et al., 2013a), and extend them by revealing a tight correlation between the extent to which the activity of Purkinje cells is erratic with the severity of the motor abnormalities. Because a significant amount of sensory information converges on the cerebellum, one might consider the alternative hypothesis that the erratic activity of Purkinje cells in the tottering mice during the attacks simply reflects the abnormal sensory input caused by the signs. Three sets of observations make this unlikely and support the working hypothesis that the erratic activity of Purkinje cells causes the abnormal motor signs. The ...

Cerebral Palsy (CP) - JKMAASS Foundation  Cerebral Palsy (CP) - JKMAASS Foundation
Cerebral palsy can be grouped into three main types which describe the disorders or movement and posture that may be experienced by a person. These are called spasticity, athetosis and ataxia.. Spasticity occurs when muscles are high in tone (tension) but weak in strength. A person experiencing spasticity may have difficulty moving their limbs and adopting stable posture.. Athetosis refers to uncontrolled movements, which are often most noticeable when a person with this type of cerebral palsy commences movement. In addition, children with athetoid cerebral palsy often have very weak muscles or feel floppy when they are carried.. Ataxia is characterised by unsteady, shaky movements or tremor. People with ataxic cerebral palsy and related disabilities have difficulty using muscles to achieve balance and coordinated movement. This is the least common type of cerebral palsy and related disabilities.. It is important to note that the movement difficulties each person has will be unique. Often a ...

ataxia consist of gait impairment, unclear ("scanning") speech, visual blurring due to nystagmus, hand incoordination, and tremor with movement. These result from the involvement of the cerebellum and its afferent and efferent pathways, including the spinocerebellar pathways, and the frontopontocerebellar pathway originating in the rostral frontal lobe. True cerebellar ataxia must be distinguished from ataxia associated with vestibular nerve or labyrinthine disease, as the latter results in a disorder of gait associated with a significant degree of dizziness, light-headedness, or the perception of movement (Chap. 21). True cerebellar ataxia is devoid of these vertiginous complaints and is clearly an unsteady gait due to imbalance. Sensory disturbances can also on occasion simulate the imbalance of cerebellar disease; with sensory ataxia, imbalance dramatically worsens when visual input is removed (Romberg sign). Rarely, weakness of proximal leg muscles mimics cerebellar disease. In the patient ...

DMOZ - Health: Conditions and Diseases: Neurological Disorders: Cerebral Palsy  DMOZ - Health: Conditions and Diseases: Neurological Disorders: Cerebral Palsy
Cerebral Palsy is a term used to describe a group of chronic conditions affecting body movements and muscle coordination. It is caused by damage to the brain, usually occurring during fetal development, or during infancy. It can also occur before, during or shortly following birth. Cerebral Palsy is neither progressive (it doesnt get worse with time), nor communicable (you cant catch it). It is one of the most common disabling conditions of childhood. There are 4 types of Cerebral Palsy: Spastic Cerebral Palsy characterized by stiff and difficult movement; Athetoid Cerebral Palsy characterized by involuntary and uncontrolled movement; Ataxic Cerebral Palsy characterized by a disturbed sense of balance and depth perception; and Mixed Cerebral Palsy.

ATAXIA : Neurology Now  ATAXIA : Neurology Now
A The word "ataxia" is used to describe a symptom-lack of coordination-which can be associated with injuries or degenerative changes in the central nervous system. Examples of such injuries and changes include stroke, multiple sclerosis, head injury, or alcoholism. This is known as acquired ataxia.. Ataxia also indicates a group of specific degenerative and progressive diseases of the nervous system called the hereditary and sporadic ataxias. These diseases damage parts of the nervous system that control movement. Often the first apparent symptom of these disorders is difficulty with balance and walking. Symptoms of hereditary ataxias commonly begin in childhood, but one type-Friedreichs ataxia-has an adult onset in some cases. People with Friedreichs ataxia develop weakness in the muscles of the feet, lower legs, and hands. They often rely on a wheelchair within 15 years of the appearance of symptoms. As the disease progresses, patients may experience slow, slurred speech; rapid, involuntary ...

Episodic ataxia - Breda Genetics srl  Episodic ataxia - Breda Genetics srl
Episodic ataxia can occur sporadically or in a number of hereditary disorders, like for instance in pyruvate carboxylase deficiency (PC gene) and pyruvate dehydrogenase deficiency (PDHA1 gene). In addition, mutations in the OTC gene, which may be evident as partial deficiency in females and complete deficiency in males, can cause episodic extreme irritability, episodic vomiting and lethargy, protein avoidance, ataxia, stage II coma, delayed growth, developmental delay, and seizures. Hyperammonemias caused by deficiencies of urea cycle enzymes (CPS1, ASS1, ASL, ARG1 gene mutations) are characterized by intermittent ataxia, dysarthria, vomiting, headache, ptosis, involuntary movements, seizures, and confusion. Aminoacidurias may also be a significant part of the differential diagnosis of episodic ataxias: Hartnup disease (SLC6A19 gene mutations), maple syrup urine disease (MSUD, caused by BCKDHA, BCKDH, DBT, or DLD gene mutation), and isovaleric acidemia (IVD gene mutation).

To date, 43 types of Spinocerebellar Ataxias (SCAs) have been identified. A subset of the SCAs are caused by the pathogenic expansion of a CAG repeat tract within the corresponding gene. Ethnic and geographic differences are evident in the prevalence of the autosomal dominant SCAs. Few descriptions of the clinical phenotype and molecular genetics of the SCAs are available from the African continent. Established studies mostly concern the South African populations, where there is a high frequency of SCA1, SCA2 and SCA7. The SCA7 mutation in South Africa (SA) has been found almost exclusively in families of indigenous Black African ethnic origin. To present the results of the first clinical description of seven Zambian families presenting with autosomal dominant SCA, as well as the downstream molecular genetic analysis of a subset of these families.
