Sensory functions that transduce stimuli received by proprioceptive receptors in joints, tendons, muscles, and the INNER EAR into neural impulses to be transmitted to the CENTRAL NERVOUS SYSTEM. Proprioception provides sense of stationary positions and movements of one's body parts, and is important in maintaining KINESTHESIA and POSTURAL BALANCE.
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.
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.
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.
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.
A mechanism of communicating one's own sensory system information about a task, movement or skill.
Nerve structures through which impulses are conducted from a nerve center toward a peripheral site. Such impulses are conducted via efferent neurons (NEURONS, EFFERENT), such as MOTOR NEURONS, autonomic neurons, and hypophyseal neurons.
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)
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.
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.

A heterogenous group of degenerative syndromes marked by progressive cerebellar dysfunction either in isolation or combined with other neurologic manifestations. Sporadic and inherited subtypes occur. Inheritance patterns include autosomal dominant, autosomal recessive, and X-linked.
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.

Cerebellar degeneration associated with a remote neoplasm. Clinical manifestations include progressive limb and GAIT ATAXIA; DYSARTHRIA; and NYSTAGMUS, PATHOLOGIC. The histologic type of the associated neoplasm is usually carcinoma or lymphoma. Pathologically the cerebellar cortex and subcortical nuclei demonstrate diffuse degenerative changes. Anti-Purkinje cell antibodies (anti-Yo) are found in the serum of approximately 50% of affected individuals. (Adams et al., Principles of Neurology, 6th ed, p686)

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.
An ancient country in western Asia, by the twentieth century divided among the former USSR, Turkey, and Iran. It was attacked at various times from before the 7th century B.C. to 69 B.C. by Assyrians, Medes, Persians, the Greeks under Alexander, and the Romans. It changed hands frequently in wars between Neo-Persian and Roman Empires from the 3d to 7th centuries and later under Arabs, Seljuks, Byzantines, and Mongols. In the 19th century Armenian nationalism arose but suffered during Russo-Turkish hostilities. It became part of the Soviet Republic in 1921, with part remaining under Turkey.

Genetics of the SCA6 gene in a large family segregating an autosomal dominant "pure" cerebellar ataxia. (1/449)

Spinocerebellar ataxia type 6 (SCA6) is an autosomal dominant cerebellar degeneration caused by the expansion of a CAG trinucleotide repeat in the CACNA1A gene. Mutations in patients are characterised by expanded alleles of between 21 and 30 repeat units and by extreme gonadal stability when transmitted from parents to children. We have investigated the SCA6 mutation in a large Spanish kindred in which previously reported spinocerebellar SCA genes and loci had been excluded. We observed a 23 CAG repeat expanded allele in the 13 clinically affected subjects and in three out of 10 presymptomatic at risk subjects. Transmission of the mutant allele was stable in six parent to child pairs and in 29 meioses through the pedigree. Linkage analysis with the SCA6-CAG polymorphism and marker D19S221 confirmed the location of SCA6 on chromosome 19p13. The molecular findings in this large family confirm the expansion of the CAG repeat in the CACNA1A gene as the cause of SCA6 and the high meiotic stability of the repeat.  (+info)

Mutation of a putative mitochondrial iron transporter gene (ABC7) in X-linked sideroblastic anemia and ataxia (XLSA/A). (3/449)

X-linked sideroblastic anemia and ataxia (XLSA/A) is a recessive disorder characterized by an infantile to early childhood onset of non-progressive cerebellar ataxia and mild anemia with hypochromia and microcytosis. A gene encoding an ATP-binding cassette (ABC) transporter was mapped to Xq13, a region previously shown by linkage analysis to harbor the XLSA/A gene. This gene, ABC7, is an ortholog of the yeast ATM1 gene whose product localizes to the mitochondrial inner membrane and is involved in iron homeostasis. The full-length ABC7 cDNA was cloned and the entire coding region screened for mutations in a kindred in which five male members manifested XLSA/A. An I400M variant was identified in a predicted transmembrane segment of the ABC7 gene in patients with XLSA/A. The mutation was shown to segregate with the disease in the family and was not detected in at least 600 chromosomes of general population controls. Introduction of the corresponding mutation into the Saccharomyces cerevisiae ATM1 gene resulted in a partial loss of function of the yeast Atm1 protein. In addition, the human wild-type ABC7 protein was able to complement ATM1 deletion in yeast. These data indicate that ABC7 is the causal gene of XLSA/A and that XLSA/A is a mitochondrial disease caused by a mutation in the nuclear genome.  (+info)

Acute cerebellar ataxia with human parvovirus B19 infection. (4/449)

A 2 year old boy developed acute cerebellar ataxia in association with erythema infectiosum. During the disease, genomic DNA and antibodies against human parvovirus B19 were detected in serum but not in cerebrospinal fluid. Parvovirus B19 associated acute cerebellar ataxia might occur due to transient vascular reaction in the cerebellum during infection.  (+info)

Molecular and clinical study of 18 families with ADCA type II: evidence for genetic heterogeneity and de novo mutation. (5/449)

The SCA7 mutation has been found in 54 patients and 7 at-risk subjects from 17 families who have autosomal dominant cerebellar ataxia (ADCA) II with progressive pigmentary maculopathy. In one isolated case, haplotype reconstruction through three generations confirmed a de novo mutation owing to paternal meiotic instability. Different disease-associated haplotypes segregated among the SCA7-positive kindreds, which indicated a multiple origin of the mutation. One family with the clinical phenotype of ADCA type II did not have the CAG expansion that indicated locus heterogeneity. The distribution of the repeat size in 944 independent normal chromosomes from controls, unaffected at-risk subjects, and one affected individual fell into two ranges. The majority of the alleles were in the first range of 7-19 CAG repeats. A second range could be identified with 28-35 repeats, and we provide evidence that these repeats represent intermediate alleles that are prone to further expansion. The repeat size of the pathological allele, the widest reported for all CAG-repeat disorders, ranged from 37 to approximately 220. The repeat size showed significant negative correlation with both age at onset and age at death. Analysis of the clinical features in the patients with SCA7 confirmed that the most frequently associated features are pigmentary maculopathy, pyramidal tract involvement, and slow saccades. The subjects with <49 repeats tended to have a less complicated neurological phenotype and a longer disease duration, whereas the converse applied to subjects with >/=49 repeats. The degree of instability during meiotic transmission was greater than in all other CAG-repeat disorders and was particularly striking in paternal transmission, in which a median increase in repeat size of 6 and an interquartile range of 12 were observed, versus a median increase of 3 and interquartile range of 3.5 in maternal transmission.  (+info)

Decreased cerebellar blood flow in postinfectious acute cerebellar ataxia. (6/449)

OBJECTIVE: The aim of the present study was to evaluate the regional cerebral blood flow (rCBF) in patients with postinfectious acute cerebellar ataxia using single photon emission computed tomography (SPECT). METHODS: Five children with postinfectious acute cerebellar ataxia and five control subjects were examined. The distribution of rCBF was measured by SPECT imaging after intravenous administration of 123I-IMP (111 MBq). The rCBF ratio-defined as the ratio of rCBF in the region of interest (ROI) to that in the occipital cortex-was calculated for each cortical and subcortical ROI. The mean rCBF ratio of each region was then compared between the ataxic and control subjects. These patients and all control subjects were also evaluated using MRI. RESULTS: The rCBF ratio was significantly lower in the cerebellum of the ataxic patients than in the cerebellum of the control subjects (p<0.05). No abnormal cerebellar morphology and no abnormal signal intensities were found on MRI. CONCLUSION: 123I-IMP SPECT clearly demonstrated the decreased rCBF in the cerebellum of all patients with postinfectious acute cerebellar ataxia.  (+info)

Trinucleotide repeat expansion of spinocerebellar ataxia (SCA1) found in a Chinese family. (7/449)

OBJECTIVE: To investigate the gene mutation and the ratio of the spinocerebellar ataxia type 1 (SCA1) in Chinese patients with autosomal dominant spinocerebellar ataxia (ADSCA). METHOD: The family material and DNA samples were collected from thirteen families with ADSCA. To determine the characteristics of the CAG trinucleotide repeats in SCA1 gene, the PCR products of the Rep1 and Rep2 primers were analyzed, and the bands with CAG repeat expansion were cloned by PCR2. 1 vector and sequenced. RESULTS: One family was found to have an expanded CAG repeat in the 13 families with ADSCA. The clinically affected individual was heterozygous with one disease allele being 55 CAG repeats, whereas the mean size of the CAG repeats on 104 chromosomes generated from unrelated control Chinese individuals is 29.3 (ranging from 18 to 34). CONCLUSIONS: The frequency of the SCA1 mutation is about 7% in the 13 Chinese families with ADSCA, suggesting that this type of genetic defect is not the main cause involved in the pathogenesis of ADSCA in China. Since the mutation has also been found in Caucasian, Japanese, Malaysian, and Bangladeshi kindreds, it is suggested that this genetic defect may well have multiple origins in different ethnic groups.  (+info)

Comparative analysis of gait in Parkinson's disease, cerebellar ataxia and subcortical arteriosclerotic encephalopathy. (8/449)

Quantitative gait analysis has been used to elucidate characteristic features of neurological gait disturbances. Although a number of studies compared single patient groups with controls, there are only a few studies comparing gait parameters between patients with different neurological disorders affecting gait. In the present study, gait parameters were compared between control subjects, patients with parkinsonian gait due to idiopathic Parkinson's disease, subjects suffering from cerebellar ataxia and patients with gait disturbance due to subcortical arteriosclerotic encephalopathy. In addition to recording of baseline parameters during preferred walking velocity, subjects were required to vary velocity from very slow to very fast. Values of velocity and stride length from each subject were then used for linear regression analysis. Whereas all patient groups showed slower walking velocity and reduced step length compared with healthy controls when assessed during preferred walking, patients with ataxia and subcortical arteriosclerotic encephalopathy had, in addition, increased variability of amplitude and timing of steps. Regression analysis showed that with changing velocity, subjects with Parkinson's disease changed their stride length in the same proportion as that measured in controls. In contrast, patients with ataxia and subcortical arteriosclerotic encephalopathy had a disproportionate contribution of stride length when velocity was increased. Whereas the findings in patients with Parkinson's disease can be explained as a reduction of force gain, the observations for patients with ataxia and subcortical arteriosclerotic encephalopathy reflect an altered spatiotemporal gait strategy in order to compensate for instability. The similarity of gait disturbance in subcortical arteriosclerotic encephalopathy and cerebellar ataxia suggests common mechanisms.  (+info)

Course and Outcome of Acute Cerebellar Ataxia Anne M. Connolly, MD, W. Edwin Dodson, MD, Arthur L. Prensky, MD, and Robert S. Rust, MD?$ We report a study of 73 consecutive children with acute cerebellar ataxia, representing all of the children evaluated at St. Louis Childrens Hospital during a 23-year-period to whom this diagnosis could appropriately be assigned. 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. One fifth of the children followed for more than 4 ...

Chapter 37 - Acute Inflammatory Diseases of the Cerebellum. Marc Tardieu. Acute ataxia may be the consequence of an inflammatory reaction within the central nervous system (CNS). In this chapter, after a short overview on neuroimmunological aspects, the most classic benign acute inflammatory cerebellar ataxia will be reviewed, followed by a discussion of more severe forms. Acute cerebellar ataxia is sometimes differentiated, in reviews and chapters, from acute cerebellitis, the latter being more severe (Gill 2010). In this chapter the two terms are considered as equivalent with benign and severe forms, acute cerebellar ataxia being a clinical description and acute cerebellitis referring to the pathophysiology. In the later section, the autoimmune diseases, which may start as an acute infl ammatory cerebellar ataxia but are usually relapsing, will be reviewed, followed by a discussion of differential diagnosis. The four chapters in Part 8: Acute Ataxia provide a detailed overview of the causes ...
Hereditary cerebellar degenerations are a heterogeneous group of diseases often having a detrimental impact on patients quality of life. Unfortunately, no sufficiently effective causal therapy is available for human patients at present. There are several therapies that have been shown to affect the pathogenetic process and thereby to delay the progress of the disease in mouse models of cerebellar ataxias. The second experimental therapeutic approach for hereditary cerebellar ataxias is neurotransplantation. Grafted cells might provide an effect via delivery of a scarce neurotransmitter, substitution of lost cells if functionally integrated and rescue or trophic support of degenerating cells. The results of cerebellar transplantation research over the past 30 years are reviewed here and potential benefits and limitations of neurotransplantation therapy are discussed.

Although the clinical presentation varied considerably in the six patients, they all shared three fundamental features: cerebellar ataxia, cerebellar atrophy, and muscle CoQ10 deficiency responsive to CoQ10 supplementation.. The serendipitous finding of low CoQ10 content in the muscle biopsy of Patient 3 and the dramatic response of this patient and his affected siblings (Patients 4 and 5) to CoQ10 supplementation prompted us to measure CoQ10 in muscle biopsies from three other patients with undiagnosed, apparently autosomal recessive ataxia. All three had similar decreases of CoQ10 concentration in muscle and all three responded clearly to replacement therapy, suggesting the possibility that ataxia and cerebellar atrophy may be the consequence of primary CoQ10 deficiency.. Primary muscle CoQ10 deficiency was first described in 1989 in two sisters with recurrent episodes of myoglobinuria and muscle biopsies characterized by RRF and lipid storage.1 Three other patients with the same syndrome were ...
We demonstrate genetic and biochemical data in a family with a novel frameshift mutation in the ADCK3 gene and with the phenotype of a complex ataxia-myoclonus syndrome, CoQ10 deficiency and abnormal MRC enzyme activities. One of the unusual features of this family is an onset in the second decade, which is later than most previously reported cases with ADCK3 mutations. Also, this family was affected with marked myoclonic-dystonic movements but relatively mild cerebellar ataxia, suggesting a wide phenotypic spectrum of ADCK3 mutations.. To date, autosomal recessive mutations in ADCK3 have only been identified in 22 patients from 13 families, and these mutations have been associated with clinically heterogeneous diseases.9 Patients usually present with a complex neurological phenotype, with cerebellar ataxia as the predominant manifestation.8-11 In this family, cerebellar symptoms were relatively mild compared to the disabling myoclonus and involuntary movements which affected both siblings. ...
The cerebellar ataxias are a group of incurable brain disorders that are caused primarily by the progressive dysfunction and degeneration of cerebellar Purkinje cells. The lack of reliable disease models for the heterogeneous ataxias has hindered the understanding of the underlying pathogenic mechanisms as well as the development of effective therapies for these devastating diseases. Recent advances in the field of induced pluripotent stem cell (iPSC) technology offer new possibilities to better understand and potentially reverse disease pathology. Given the neurodevelopmental phenotypes observed in several types of ataxias, iPSC-based models have the potential to provide significant insights into disease progression, as well as opportunities for the development of early intervention therapies. To date, however, very few studies have successfully used iPSC-derived cells to model cerebellar ataxias. In this review, we focus on recent breakthroughs in generating human iPSC-derived Purkinje cells. We also
Objective: To ascertain the genetic and functional basis of complex autosomal recessive cerebellar ataxia (ARCA) presented by 2 siblings of a consanguineous family characterized by motor neuropathy, cerebellar atrophy, spastic paraparesis, intellectual disability, and slow ocular saccades.. Methods: Combined whole-genome linkage analysis, whole-exome sequencing, and focused screening for identification of potential causative genes were performed. Assessment of the functional consequences of the mutation on protein function via subcellular fractionation, size-exclusion chromatography, and fluorescence microscopy were done. A zebrafish model, using Morpholinos, was generated to study the pathogenic effect of the mutation in vivo.. Results: We identified a biallelic 3-bp deletion (p.K19del) in that cosegregates with the disease.

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
The cerebellum plays crucial roles in controlling sensorimotor functions. The neural output from the cerebellar cortex is transmitted solely by Purkinje cells (PCs), whose impairment causes cerebellar ataxia. Parallel fiber (PF) to PC synaptic transmission is mediated by postsynaptic ionotropic glutamate receptors and the metabotropic glutamate receptor subtype 1 (mGluR1). Previous studies including knockout of the mGluR1 or blockade of mGluR1 function by the specific antibody showed that mGluR signaling is crucial for cerebellar function and that defect of mGluR signaling results in severe ataxia. Spinocerebellar ataxia type 1 (SCA1) is a progressive neurodegenerative disorder caused by the expansion of a polyglutamine tract in the ataxin-1 protein. The onset is approximately 4th decade of the life and the patients show progressive cerebellar ataxia. To date, no fundamental treatments for SCA1 have been elucidated. We found that SCA1 model mice show selective impairment of mGluR signaling in ...
Serological testing for anti-neural autoantibodies is important in patients presenting with idiopathic cerebellar ataxia, since these autoantibodies may indicate cancer, determine treatment and predict prognosis. While some of them target nuclear antigens present in all or most CNS neurons (e.g. anti-Hu, anti-Ri), others more specifically target antigens present in the cytoplasm or plasma membrane of Purkinje cells (PC). In this series of articles, we provide a detailed review of the clinical and paraclinical features, oncological, therapeutic and prognostic implications, pathogenetic relevance, and differential laboratory diagnosis of the 12 most common PC autoantibodies (often referred to as Medusa head antibodies due to their characteristic somatodendritic binding pattern when tested by immunohistochemistry). To assist immunologists and neurologists in diagnosing these disorders, typical high-resolution immunohistochemical images of all 12 reactivities are presented, diagnostic pitfalls discussed

The autosomal dominant cerebellar ataxias (ADCA) are a heterogeneous group of neurodegenerative disorders characterized by progressive degeneration of the cerebellum, brain stem and spinal cord. Clinically, ADCA has been divided into three groups: ADCA types I-III. ADCAI is genetically heterogeneous, with five genetic loci, designated spinocerebellar ataxia (SCA) 1, 2, 3, 4 and 6, being assigned to five different chromosomes. ADCAII, which always presents with retinal degeneration (SCA7), and ADCAIII often referred to as the `pure cerebellar syndrome (SCA5), are most likely homogeneous disorders. Several SCA genes have been cloned and shown to contain CAG repeats in their coding regions. ADCA is caused by the expansion of the CAG repeats, producing an elongated polyglutamine tract in the corresponding protein. The expanded repeats are variable in size and unstable, usually increasing in size when transmitted to successive generations. The function of the ataxins is not known. This locus has ...
We present a 7-year-old boy with acute cerebellitis who required an emergency ventriculoperitoneal shunt for hydrocephalus caused by cerebellar swelling. This represents a very unusual, potentially life-threatening complication of a usually self-limiting condition. Early diagnosis of this complication is essential in view of the propensity to sudden and fatal deterioration. Magnetic resonance imaging (MRI) is useful in differentiating this unusual course of acute cerebellar ataxia from that of a posterior fossa tumor. In developing countries, however, computed tomography (CT) is often the only existing diagnostic modality and access to MRI, when available, is limited. Our case demonstrates that the shape of the fourth ventricle on CT can be helpful in differentiating between a tumor and edema of the cerebellum and thus can assist in management ...

We report on a serum autoantibody associated with cerebellar ataxia. performed to rule out a broad panel of previously described paraneoplastic and non-paraneoplastic anti-neural autoantibodies. The characteristic binding pattern as well as double staining experiments suggested inositol 1 4 5 receptor type 1 (ITPR1) as the target antigen. Verification of the antigen included specific neutralization of the tissue reaction following preadsorption with ITPR1 (but not ARHGAP26) and a dot-blot assay with purified ITPR1 protein. By contrast anti-ARHGAP26-positive sera did not bind to ITPR1. In a parallel approach a combination of histoimmunoprecipitation and mass spectrometry also identified ITPR1 as the target antigen. Finally a recombinant cell-based immunofluorescence assay using HEK293 cells expressing ITPR1 and ARHGAP26 respectively confirmed the identification of ITPR1. Mutations of ITPR1 have previously been implicated in spinocerebellar ataxia with and without cognitive decline. Our findings ...

Spongy Degeneration with Cerebellar Ataxia, (SDCA2) is an inherited disease affecting the Belgian Shepherd breed. It is a severe neurodegenerative disease with monogenic autosomal recessive inheritance. The disease is characterised by rapidly progressing ataxia starting around the age of 5-8 weeks. Puppies are usually euthanised by the age of 8-12 weeks. The disease can also be caused by another mutation SDCA2 . We also offer a combined SDCA1 + SDCA2 test in this breed. .
|jats:p|Induced pluripotent stem cell (iPSC) technology has emerged as an important tool in understanding, and potentially reversing, disease pathology. This is particularly true in the case of neurodegenerative diseases, in which the affected cell types are not readily accessible for study. Since the first descriptions of iPSC-based disease modelling, considerable advances have been made in understanding the aetiology and progression of a diverse array of neurodegenerative conditions, including Parkinsons disease and Alzheimers disease. To date, however, relatively few studies have succeeded in using iPSCs to model the neurodegeneration observed in cerebellar ataxia. Given the distinct neurodevelopmental phenotypes associated with certain types of ataxia, iPSC-based models are likely to provide significant insights, not only into disease progression, but also to the development of early-intervention therapies. In this review, we describe the existing iPSC-based disease models of this heterogeneous

Ataxia with oculomotor apraxia type 1 is an autosomal-recessive neurodegenerative disorder characterized by a childhood onset of slowly progressive cerebellar ataxia, followed by oculomotor apraxia and a severe primary motor peripheral axonal motor neuropathy. Ataxia with oculomotor apraxia type 1 is caused by bi-allelic mutations in APTX (chromosome 9p21.1). Our patient has a clinical presentation that is typical for ataxia with oculomotor apraxia type 1 with no particularly severe phenotype. Multiplex Ligation-dependent Probe Amplification analysis resulted in the identification of a homozygous deletion of all coding APTX exons (3 to 9). SNP array analysis using the Illumina Infinium CytoSNP-850 K microarray indicated that the deletion was about 62 kb. Based on the SNP array results, the breakpoints were found using direct sequence analysis: c.-5 + 1225_*44991del67512, p.0?. Both parents were heterozygous for the deletion. Homozygous complete APTX deletions have been described in literature for two
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 ...

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)
Communication difficulties have considerable impact on people with progressive ataxia, yet there are currently no evidence-based treatments. LSVT LOUD® focuses on the production of healthy vocal loudness whilst also improving breath support, vocal quality, loudness and articulation in participating patients. This study aimed to investigate whether Lee Silverman Voice Treatment (LSVT LOUD®) can improve communication effectiveness in these patients. We performed a rater-blinded, single-arm study investigating LSVT LOUD® treatment in a population of patients with progressive ataxia including Friedreichs ataxia (n = 18), spinocerebellar ataxia type 6 (n = 1), idiopathic cerebellar ataxia (n = 1), and spastic paraplegia 7 (n = 1). Twenty-one patients were recruited to the study, with 19 completing treatment. Sessions were administered via Skype in the LSVT-X format, meaning two sessions per week over a period of 8 weeks. Assessments included two baseline and two post-treatment measures and ...

Severe acute respiratory syndrome virus 2 (SARS-CoV-2) is spreading globally and causes most frequently fever and respiratory symptoms, i.e. Coronavirus disease 2019 (COVID-19), however, distinct neurological syndromes associated with SARS-CoV-2 infection have been described. Among SARS-CoV-2-infections-associated neurological symptoms fatigue, headache, dizziness, impaired consciousness and anosmia/ageusia are most frequent, but less frequent neurological deficits such as seizures, Guillain-Barré syndrome or ataxia may also occur. Herein we present a case of a 62-year-old man who developed a subacute cerebellar syndrome with limb-, truncal- and gait ataxia and scanning speech 1 day after clinical resolution of symptomatic SARS-CoV-2 infection of the upper airways. Apart from ataxia, there were no signs indicative of opsoclonus myoclonus ataxia syndrome or Miller Fisher syndrome. Cerebral magnetic resonance imaging showed mild cerebellar atrophy. SARS-CoV-2 infection of the cerebellum was excluded by
The suggested link between autism and cerebellar dysfunction formed the background for a Swedish clinical study in 2001. Thirty-two children (17 females, 15 males; mean age 12y, SD 3y 10mo; range 6 to 21y) with a clinical suspicion of non-progressive congenital ataxia were examined, and parents were interviewed about the presence of neuropsychiatric problems in the child. Twelve children had simple ataxia, eight had ataxic diplegia, and 12 had borderline ataxia. All but one of the 32 children had a mild to moderate gross motor disability according to Gross Motor Function Classification System (15 were categorized as level I, 16 as level II, and one child as level IV). Neuroimaging and neuropsychological testing were achieved in most cases. There was a strong association between learning disability* and autism spectrum disorder (often combined with hyperactivity disorder) on the one hand, and both simple and borderline ataxia on the other, but a weaker link between ataxic diplegia and ...
DNA methyltransferase 1 (EC 2.1.1.37), encoded by DNMT1 gene, is one of key enzymes in maintaining DNA methylation patterns of the human genome. It plays a crucial role in embryonic development, imprinting and genome stability, cell differentiation. The dysfunction of this group of enzymes can lead to a variety of human genetic disorders. Until now, mutations in DNMT1 have been found to be associated with two distinct phenotypes. Mutations in exon 20 of this gene leads to hereditary sensory and autonomic neuropathy type IE, and mutations in exon 21 cause autosomal dominant cerebellar ataxia, deafness and narcolepsy. Here we report a novel DNMT1 mutation in a sporadic case of a Chinese patient with cerebellar ataxia, multiple motor and sensory neuropathy, hearing loss and psychiatric manifestations. Furthermore, we elucidated its pathogenic effect through molecular genetics studies and revealed that this defective DNMT1 function is responsible for the phenotypes in this individual. Our findings expand
Olivopontocerebellar atrophy (OPA) is an uncommon but serious neurological disorder. It causes nerve tissue degeneration and atrophy in the brain. Doctors believe that OPA is similar to a multiple system atrophy (MSA) disorder. Different MSA disorders occur in different sites within the brain.. OPA shares many symptoms with MSA disorders. One common symptom is ataxia. Ataxia is a difficulty in controlling your muscle movements for gait. Diagnosing OPA can be challenging because so many of the symptoms mirror those of MSA disorders. Neurological disorders also share symptoms with OPA. For example, Parkinsons disease can look similar to OPA. Some of the shared symptoms include tremors and balance problems. Diagnostic imaging tests help neurologists look for areas of damage and diagnose disorders.. Theres no cure for OPA. Doctors are able to offer treatment that helps patients live as long as possible. The life expectancy for people with OPA differs because brains degenerate at different ...

Olivopontocerebellar atrophy (OPCA) refers to a group of ataxias characterized by progressive neurological degeneration affecting the cerebellum, the pons and the inferior olives.
Olivopontocerebellar atrophy (OPCA) is a neurodegenerative syndrome characterized by prominent cerebellar and extrapyramidal signs, dysarthria, and dysphagia. Those who study OPCA quickly learn that it is not a single entity, and that its nosology can be confusing.
Episodic ataxia type 2 (EA2) is a channelopathy caused by mutations in the CACNA1A gene that encodes for the pore subunit of P/Q type voltage gated Ca+2 channels. Patients carrying these mutations display baseline cerebellar ataxia and episodes of severe ataxia and dystonia. The episodes can last from a few hours to a couple of days, and are triggered by physical or emotional stress, or caffeine or alcohol consumption. The mechanisms by which the stressors induce the episodes are not known. In this thesis, using a well-established mouse model of EA2, tottering, we sought to delineate the mechanisms underlying trigger-induced motor attacks. Because cerebellar Purkinje cells (PCs) are known to be required for the expression of attacks in tottering mice, we focused our studies on the physiology of these cells. In the past decade our lab has extensively studied the conductances regulating intrinsic pacemaking of PCs. Through this comprehensive work it was established that the only conductance that ...
Clinicoanatomic correlation in the spinocerebellar ataxias (SCA) and Friedreichs ataxia (FRDA) is difficult as these diseases differentially affect multiple sites in the central and peripheral nervous systems. A new way to study cerebellar ataxia is the systematic analysis of the reciprocal cerebellar circuitry that consists of tightly organized reciprocal connections between Purkinje cells, dentate nuclei (DN), and inferior olivary nuclei (ION). This circuitry is similar to but not identical with the cerebellar module in experimental animals.. Read More: The Reciprocal Cerebellar Circuitry in Human Hereditary Ataxia. ...
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 ...
A cross-departmental collaboration involving Associate Professor Esther Becker and Lauren Watson, a research scientist in the Becker group, has led to the publication of an important paper reporting dominant mutations that cause spinocerebellar ataxias. Spinocerebellar ataxias are a group of diseases that cause degeneration in the cerebellum, which is the part of the brain responsible for controlling movement. Whilst there many different types of this disorder, each with their own unique symptoms, generally the disorder is characterised by problems with movement that worsen over time. The paper, published in the American Journal of Human Genetics, describes a series of mutations in a human gene called GRM1, which produces a glutamate receptor known as mGlur1. mGlur1 is one of the most abundant of its group of receptors in the Central Nervous System and is particularly rich in the group of brain cells in the cerebellum known as Purkinje cells. Disease causing mutations in GRM1 are quite rare.; ...

From NCBI Gene:. The protein encoded by this gene is a member of the family of ionotropic glutamate receptors which are the predominant excitatory neurotransmitter receptors in the mammalian brain. The encoded protein is a multi-pass membrane protein that is expressed selectively in cerebellar Purkinje cells. A point mutation in the mouse ortholog, associated with the phenotype named lurcher, in the heterozygous state leads to ataxia resulting from selective, cell-autonomous apoptosis of cerebellar Purkinje cells during postnatal development. Mice homozygous for this mutation die shortly after birth from massive loss of mid- and hindbrain neurons during late embryogenesis. This protein also plays a role in synapse organization between parallel fibers and Purkinje cells. Alternate splicing results in multiple transcript variants encoding distinct isoforms. Mutations in this gene cause cerebellar ataxia in humans. [provided by RefSeq, Apr 2014]. From UniProt: ...

Pratap-Chand et al. (1995) described 11 consecutive children with clinical and radiological features of OPCA which started in infancy. In addition to cerebellar ataxia, these children also had sensorineural deafness and speech impairment. Of the present cases, 8 were sporadic and the pedigree patterns in 3 (with a sibling also involved) point to an autosomal recessive inheritance. The CT scan showed varying degrees of cerebellar and pontine atrophy.. Kumar et al. (1995) reported 14 children (equal males and females) with olivopontocerebellar atrophy (OPCA) who were diagnosed between 1990 and 1994 clinically and radiologicaly. All children were clinically examined and investigated (complete blood count, liver and renal functions, CSF examination, immunoglobulins, lipid profile, lactic acid ceruplasmin, and uric acid levels).

Patients with Hodgkins disease can develop paraneoplastic cerebellar ataxia because of the generation of autoantibodies against mGluR1 (mGluR1-Abs). Yet, the pathophysiological mechanisms underlying their motor coordination deficits remain to be elucidated. Here, we show that application of IgG purified from the patients serum to cerebellar slices of mice acutely reduces the basal activity of Purkinje cells, whereas application to the flocculus of mice in vivo evokes acute disturbances in the performance of their compensatory eye movements. In addition, the mGluR1-Abs block induction of long-term depression in cultured mouse Purkinje cells, whereas the cerebellar motor learning behavior of the patients is affected in that they show impaired adaptation of their saccadic eye movements. Finally, postmortem analysis of the cerebellum of a paraneoplastic cerebellar ataxia patient showed that the number of Purkinje cells was significantly reduced by approximately two thirds compared with three ...

It can be given orally or parenterally: the bioavailability of oral doses of methotrexate is highly variable, being only two-thirds of that by parenteral use. The most frequent side effects are nausea and vomiting, and the most serious are toxicity of the bone marrow, liver, kidney and mucosa. Being hydrophilic, methotrexate barely penetrates the blood-brain barrier so that central nervous system toxicity is rare. However, this may follow intrathecal or high-dose intravenous administration, as used to treat haematological malignancies. There are a few case reports of leukoencephalopathy after low-dose oral methotrexate, involving the temporal and/or occipital lobes or the cerebellum.1 Subcutaneous administration of methotrexate seems to give a better clinical response and fewer side effects than oral methotrexate.2 Nevertheless, we recently observed a woman … ...
COVID-19 outbreak profoundly impacted on daily-life of patients with neurodegenerative diseases, including those with ataxia. Effects on interventional trials have been recently described. Conversely, changes in physical activity programs, which are crucial in care of ataxic patients, have not been assessed yet. Here we used a structured electronic survey to interview twenty patients with Friedreich ataxia (FA) on changes in physical activity during the lockdown in Italy. Regular physiotherapy was interrupted for most patients and up to 60% of them referred a substantial worsening of self-perceived global health. However, FA patients (especially those mildly affected) adopted voluntarily home-based training strategies and, in 30% of cases, used technology-based tools (TBTs) for exercise. COVID-19 crisis thus disclosed the urgent need to support ataxic patients improving systems for remote physical activity and technology-based assistance.
TY - JOUR. T1 - Chapter 22 Timing of neuronal replacement in cerebellar degenerative ataxia of Purkinje cell type. AU - Ghetti, B.. AU - Triarhou, L. C.. AU - Alyea, C. J.. AU - Low, W. C.. AU - Chang, A. C.. PY - 1990/1/1. Y1 - 1990/1/1. N2 - The Purkinje cell degeneration (pcd) mutant is characterized by a genetically determined loss of virtually all Purkinje cells between 17 and 45 days of age. The mutation is recessive; homozygous females (pcd/pcd) are fertile, whereas homozygous males are sterile. In solid cerebellar grafts, transplanted in pcd mutants, donor Purkinje cells survive and differentiate. The extent, pattern, and timing of degeneration, along with a comparative analysis of data from other cerebellar mutants characterized by Purkinje cell deficits, support the notion that all of these changes are most likely secondary to the loss of Purkinje cells. Thus, it appears that in pcd mutants as well, transneuronal losses proceed at a slower rate than losses that are under a primary ...

Ataxia Armor is a craftable Hardmode armor set, crafted from Cores of Chaos, Hellstone Bars, and Chaotic Bars. It requires 6 Cores of Chaos, 17 Hellstone Bars, and 32 Chaotic Bars to make the whole set or 10 Cores of Chaos, 33 Hellstone Bars, and 60 Chaotic Bars for a set with all five headpieces. A full set consists of an Ataxia Armor and an Ataxia Subligar as well as five different headpieces: The Ataxia Mask, Ataxia Helmet, Ataxia Helm, Ataxia Headgear and Ataxia Hood. All of the helmets share the set bonus, but also each piece providing boosts to the specific class. All helmets also provide temporary immunity to lava and immunity to fire damage. The Ataxia Armor gives 21 defense, +20 max life, 5% increased damage and critical strike chance. The Ataxia Subligar gives 15 defense, 7% increased critical strike chance and 15% increased movement speed. ...
July 25th, 2014 by Guan, X., Duan, Y., Zeng, Q., Pan, H., Qian, Y., Li, D., Cao, X., Liu, M.. Cerebellar dysfunction causes ataxia characterized by loss of balance and coordination. Until now, the molecular and neuronal mechanisms of several types of inherited cerebellar ataxia have not been completely clarified. Here we report that leucine-rich G protein-coupled receptor 4 (Lgr4/Gpr48) is highly expressed in Purkinje cells (PCs) in the cerebellum. Deficiency of Lgr4 leads to an ataxia-like phenotype in mice. Histologically, no obvious morphological changes were observed in the cerebellum of Lgr4 mutant mice. However, the number of PCs was slightly but significantly reduced in Lgr4-/- mice. In addition, in vitro electrophysiological analysis showed an impaired long-term depression (LTD) at parallel fiber-PC (PF-PC) synapses in Lgr4-/- mice. Consistently, immunostaining experiments showed that the level of phosphorylated cAMP-responsive element-binding protein (CREB) was significantly decreased ...

Journal. Human Mutation, Publication date. May 2017. Abstract. We report here the first families carrying recessive variants in the MSTO1 gene: compound heterozygous mutations were identified in two sisters and in an unrelated singleton case, who presented a multisystem complex phenotype mainly characterized by myopathy and cerebellar ataxia. Human MSTO1 is a poorly studied protein, suggested to have mitochondrial localization and to regulate morphology and distribution of mitochondria. As for other mutations affecting genes involved in mitochondrial dynamics, no biochemical defects typical of mitochondrial disorders were reported. Studies in patients fibroblasts revealed that MSTO1 protein levels were ...
