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)
A form of apraxia characterized by an acquired inability to carry out a complex motor activity despite the ability to mentally formulate the action. This condition has been attributed to a disruption of connections between the dominant parietal cortex and supplementary and premotor cortical regions in both hemispheres. (From Adams et al., Principles of Neurology, 6th ed, p57)
Impaired ambulation not attributed to sensory impairment or motor weakness. FRONTAL LOBE disorders; BASAL GANGLIA DISEASES (e.g., PARKINSONIAN DISORDERS); DEMENTIA, MULTI-INFARCT; ALZHEIMER DISEASE; and other conditions may be associated with gait apraxia.
Acquired or developmental conditions marked by an impaired ability to comprehend or generate spoken forms of language.
A cognitive disorder marked by an impaired ability to comprehend or express language in its written or spoken form. This condition is caused by diseases which affect the language areas of the dominant hemisphere. Clinical features are used to classify the various subtypes of this condition. General categories include receptive, expressive, and mixed forms of aphasia.
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)
Loss or impairment of the ability to write (letters, syllables, words, or phrases) due to an injury to a specific cerebral area or occasionally due to emotional factors. This condition rarely occurs in isolation, and often accompanies APHASIA. (From Adams et al., Principles of Neurology, 6th ed, p485; APA, Thesaurus of Psychological Index Terms, 1994)
Movement of a part of the body for the purpose of communication.
Disorders of the centrally located thalamus, which integrates a wide range of cortical and subcortical information. Manifestations include sensory loss, MOVEMENT DISORDERS; ATAXIA, pain syndromes, visual disorders, a variety of neuropsychological conditions, and COMA. Relatively common etiologies include CEREBROVASCULAR DISORDERS; CRANIOCEREBRAL TRAUMA; BRAIN NEOPLASMS; BRAIN HYPOXIA; INTRACRANIAL HEMORRHAGES; and infectious processes.
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 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).
Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS. DYSKINESIAS (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. Common etiologies include CEREBROVASCULAR DISORDERS; NEURODEGENERATIVE DISEASES; and CRANIOCEREBRAL TRAUMA.
Disorders of the quality of speech characterized by the substitution, omission, distortion, and addition of phonemes.
Perception of shape and form of objects by TOUCH, via tactile stimuli.
Impairment of the ability to coordinate the movements required for normal ambulation (WALKING) which may result from impairments of motor function or sensory feedback. This condition may be associated with BRAIN DISEASES (including CEREBELLAR DISEASES and BASAL GANGLIA DISEASES); SPINAL CORD DISEASES; or PERIPHERAL NERVOUS SYSTEM DISEASES.
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)
Measurement of parameters of the speech product such as vocal tone, loudness, pitch, voice quality, articulation, resonance, phonation, phonetic structure and prosody.
Treatment for individuals with speech defects and disorders that involves counseling and use of various exercises and aids to help the development of new speech habits.
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)
Tests designed to assess neurological function associated with certain behaviors. They are used in diagnosing brain dysfunction or damage and central nervous system disorders or injury.
A term used in Eastern European research literature on brain and behavior physiology for cortical functions. It refers to the highest level of integrative function of the brain, centered in the CEREBRAL CORTEX, regulating language, thought, and behavior via sensory, motor, and cognitive processes.
Loss of the ability to comprehend the meaning or recognize the importance of various forms of stimulation that cannot be attributed to impairment of a primary sensory modality. Tactile agnosia is characterized by an inability to perceive the shape and nature of an object by touch alone, despite unimpaired sensation to light touch, position, and other primary sensory modalities.

Pure apraxic agraphia with abnormal writing stroke sequences: report of a Japanese patient with a left superior parietal haemorrhage. (1/188)

A 67 year old Japanese male patient had pure agraphia after a haemorrhage in the left superior parietal lobule. He developed difficulty in letter formation but showed no linguistic errors, consistent with the criteria of apraxic agraphia. He manifested a selective disorder of sequencing writing strokes, although he was able to orally state the correct sequences. The patient's complete recovery after 1 month, without new learning, showed that he had manifested a selective disorder of writing stroke sequences. These findings indicate that the final stage of the execution of writing according to acquired sequential memory shown as a stroke sequence can be selectively disturbed, and should be considered to be distinct from the ability of character imagery and the knowledge of the writing stroke sequence itself. This case also indicates that the left superior parietal lobule plays an important part in the execution of writing.  (+info)

Impaired dexterity of the ipsilateral hand after stroke and the relationship to cognitive deficit. (2/188)

BACKGROUND AND PURPOSE: Previous research has reported impaired hand function on the "unaffected" side after stroke, but its incidence, origins, and impact on rehabilitation remain unclear. This study investigated whether impairment of ipsilateral dexterity is common early after middle cerebral artery stroke and explored the relationship to cognitive deficit. METHODS: Thirty patients within 1 month of an infarct involving the parietal or posterior frontal lobe (15 left and 15 right hemisphere) used the ipsilateral hand in tests that simulated everyday hand functions. Performance was compared with that of healthy age-matched controls using the same hand. Standardized tests were used to assess apraxia, visuospatial ability, and aphasia. RESULTS: All patients were able to complete the dexterity tests, but video analysis showed that performance was slow and clumsy compared with that of controls (P<0.001). Impairment was most severe after left hemisphere damage, and apraxia was a strong correlate of increased dexterity errors (P<0.01), whereas reduced ipsilateral grip strength correlated with slowing (P<0.05). The pattern of performance was different for patients with right hemisphere damage. Here there was no correlation between grip strength and slowing, while dexterity errors appeared to be due to visuospatial problems. CONCLUSIONS: Subtle impairments in dexterity of the ipsilateral hand are common within 1 month of stroke. Ipsilateral sensorimotor losses may contribute to these impairments, but the major factor appears to be the presence of cognitive deficits affecting perception and control of action. The nature of these deficits varies with side of brain damage. The effect of impaired dexterity on functional outcome is not yet known.  (+info)

Spatial deficits in ideomotor limb apraxia. A kinematic analysis of aiming movements. (3/188)

Ideomotor limb apraxia is a classic neurological disorder manifesting as a breakdown in co-ordinated limb control with spatiotemporal deficits. We employed kinematic analyses of simple aiming movements in left hemisphere-damaged patients with and without limb apraxia and a normal control group to examine preprogramming and response implementation deficits in apraxia. Damage to the frontal and parietal lobes was more common in apraxics, but neither frontal nor parietal damage was associated with different arm movement deficits. Limb apraxia was associated with intact preprogramming but impaired response implementation. The response implementation deficits were characterized by spatial but not temporal deficits, consistent with decoupling of spatial and temporal features of movement in limb apraxia. While the apraxics' accuracy was normal when visual feedback was available, it was impaired when visual feedback of either target location or hand position was unavailable. This finding suggests that ideomotor limb apraxia is associated with disruption of the neural representations for the extrapersonal (spatial location) and intrapersonal (hand position) features of movement. The non-apraxic group's normal kinematic performance demonstrates that the deficits demonstrated in the apraxic group are not simply a reflection of left hemisphere damage per se.  (+info)

Dyspraxia in a patient with corticobasal degeneration: the role of visual and tactile inputs to action. (4/188)

OBJECTIVES: To investigate the roles of visual and tactile information in a dyspraxic patient with corticobasal degeneration (CBD) who showed dramatic facilitation in miming the use of a tool or object when he was given a tool to manipulate; and to study the nature of the praxic and neuropsychological deficits in CBD. METHODS: The subject had clinically diagnosed CBD, and exhibited alien limb behaviour and striking ideomotor dyspraxia. General neuropsychological evaluation focused on constructional and visuospatial abilities, calculation, verbal fluency, episodic and semantic memory, plus spelling and writing because impairments in this domain were presenting complaints. Four experiments assessed the roles of visual and tactile information in the facilitation of motor performance by tools. Experiment 1 evaluated the patient's performance of six limb transitive actions under six conditions: (1) after he described the relevant tool from memory, (2) after he was shown a line drawing of the tool, (3) after he was shown a real exemplar of the tool, (4) after he watched the experimenter perform the action, (5) while he was holding the tool, and (6) immediately after he had performed the action with the tool but with the tool removed from his grasp. Experiment 2 evaluated the use of the same six tools when the patient had tactile but no visual information (while he was blindfolded). Experiments 3 and 4 assessed performance of actions appropriate to the same six tools when the patient had either neutral or inappropriate tactile feedback-that is, while he was holding a non-tool object or a different tool. RESULTS: Miming of tool use was not facilitated by visual input; moreover, lack of visual information in the blindfolded condition did not reduce performance. The principal positive finding was a dramatic facilitation of the patient's ability to demonstrate object use when he was holding either the appropriate tool or a neutral object. Tools inappropriate to the requested action produced involuntary performance of the stimulus relevant action. CONCLUSIONS: Tactile stimulation was paramount in the facilitation of motor performance in tool use by this patient with CBD. This outcome suggests that tactile information should be included in models which hypothesise modality specific inputs to the action production system. Significant impairments in spelling and letter production that have not previously been reported in CBD have also been documented.  (+info)

Perception of self-generated movement following left parietal lesion. (5/188)

Three apraxic patients with lesions in the left parietal cortex were required to execute finger movements with either hand, while the visual feedback they received about the movement was manipulated systematically. We used a device which allowed us to present on a video monitor either the patient's hand or the examiner's hand simultaneously performing an identical or a different movement. In each trial, patients were required to decide whether the hand shown on the screen was their own or not. Hand movements produced in response to verbal command included simple (single-finger extension) and complex gestures (multi-finger extension). Ownership judgements were analysed and compared with those produced by six normal controls and two non-apraxic neurological patients. Apraxic patients and controls accurately recognized their own hand on the screen (own movement condition) and correctly identified the viewed hand as the examiner's when it performed a movement different from their own movement (incongruent movement condition). However, when the viewed hand was the examiner's hand executing their own movement (congruent movement condition), apraxic patients were significantly more impaired than controls. When the results were analysed as a function of gesture type, the number of correct responses was significantly lower for apraxic patients with respect to controls only for complex gestures. Interestingly, when patients executed the finger gestures inaccurately, they still failed to recognize the examiner's hand as alien, and claimed that the correct movement presented on the screen was their own. These results confirm that parietal lesions alter the representational aspects of gestures, and suggest a failure in evaluating and comparing internal and external feedback about movement. We conclude that the parietal cortex plays an important role in generating and maintaining a kinaesthetic model of ongoing movements.  (+info)

Dark adaptation, motor skills, docosahexaenoic acid, and dyslexia. (6/188)

Dyslexia is a widespread condition characterized by difficulty with learning and movement skills. It is frequently comorbid with dyspraxia (developmental coordination disorder), the chief characteristic of which is impaired movement skills, indicating that there may be some common biological basis to the conditions. Visual and central processing deficits have been found. The long-chain polyunsaturated fatty acids (LCPUFAs) are important components of retinal and brain membranes. In the preliminary studies reported here, dark adaptation was shown to be impaired in 10 dyslexic young adults when compared with a similar control group (P < 0.05, repeated-measures analysis of variance); dark adaptation improved in 5 dyslexia patients after supplementation with a docosahexaenoic acid (DHA)-rich fish oil for 1 mo (P < 0.05, paired t test on final rod threshold); and movement skills in a group of 15 dyspraxic children improved after 4 mo of supplementation with a mixture of high-DHA fish oil, evening primrose oil, and thyme oil (P < 0.007 for manual dexterity, P < 0.02 for ball skills, and P < 0.03 for static and dynamic balance; paired t tests). The studies were small and had designs that did not allow firm conclusions to be made. However, when considered with other evidence from another closely related condition, attention-deficit hyperactivity disorder, for which reduced ability to elongate and desaturate the essential fatty acids linoleic acid and alpha-linolenic acid to arachidonic acid and DHA, respectively, has been proposed, the studies suggest that more research, including double-blind, placebo-controlled studies, would be useful to clarify the benefits of LCPUFAs in dyslexia and other closely related conditions.  (+info)

Portal systemic encephalopathy presenting with dressing and constructional apraxia. (7/188)

We report a case with portal systemic encephalopathy who presented with dressing and constructional apraxia and subtle weakness of the left hand. We initially suspected a cerebrovascular attack in the right cerebral hemisphere, but brain T1-weighted magnetic resonance (MR) imaging revealed high intensity in the basal ganglia and hyperammonemia was detected. We performed abdominal MR angiography, which visualized an intrahepatic portal systemic shunt. Cerebral blood flow, measured by xenon-enhanced computed tomography, was decreased in the bilateral, but more dominantly right-sided, parietal watershed regions. We speculate that these boundary territories might be susceptible to damage by toxic metabolites of hepatic encephalopathy.  (+info)

Worster-Drought syndrome, a mild tetraplegic perisylvian cerebral palsy. Review of 47 cases. (8/188)

A retrospective case-note analysis was undertaken of 47 children with a congenital upper motor neurone bulbar palsy (excluding pure speech dyspraxia) to clarify the phenotype of Worster-Drought syndrome (WDS) and to record its associated features and complications. The results revealed that the study children had significant bulbar problems (with 80% still needing a modified diet and a similar number using augmentative communication methods at last review). There were also high rates of predictable bulbar complications (86% had dribbling, 60% had glue ear, gastro-oesophageal reflux in 40%, history of poor nutrition in 40% and aspiration in 40%). Most of the children had additional complex impairments (91% had mild pyramidal tetraplegia, 81% learning difficulties, 60% congenital defects, 41% neuropsychiatric problems and 28% epilepsy). Over half of the children had significant medical problems in the first year, but mean age at diagnosis was 6 years. There were no obvious causes in pregnancy or birth. Six children had a family history of WDS and 32% (12/37) had abnormal neuroimaging including five with bilateral perisylvian polymicrogyria. In our experience, WDS is not uncommon, is relatively easily diagnosed and is crucial not to miss as the management of these children's multiple impairments is complex and requires a careful team approach. WDS falls clearly within the cerebral palsies as a syndrome that includes motor impairment arising from static damage to the brain in early life. The common presence of cognitive, behavioural and seizure impairments strongly supports the cerebral cortical (presumably perisylvian) localization. Its core elements are a suprabulbar paresis, a mild spastic tetraplegia and a significant excess of cognitive and behavioural impairments and epilepsy. The complete overlap in phenotype between WDS and the bilateral perisylvian syndrome leads us to propose that they are the same condition. WDS is startlingly absent from epidemiological studies of the cerebral palsies and rarely diagnosed, presumably because of lack of clinical awareness of the condition and lack of major gross motor impairments.  (+info)

Apraxia is a motor disorder characterized by the inability to perform learned, purposeful movements despite having the physical ability and mental understanding to do so. It is not caused by weakness, paralysis, or sensory loss, and it is not due to poor comprehension or motivation.

There are several types of apraxias, including:

1. Limb-Kinematic Apraxia: This type affects the ability to make precise movements with the limbs, such as using tools or performing complex gestures.
2. Ideomotor Apraxia: In this form, individuals have difficulty executing learned motor actions in response to verbal commands or visual cues, but they can still perform the same action when given the actual object to use.
3. Ideational Apraxia: This type affects the ability to sequence and coordinate multiple steps of a complex action, such as dressing oneself or making coffee.
4. Oral Apraxia: Also known as verbal apraxia, this form affects the ability to plan and execute speech movements, leading to difficulties with articulation and speech production.
5. Constructional Apraxia: This type impairs the ability to draw, copy, or construct geometric forms and shapes, often due to visuospatial processing issues.

Apraxias can result from various neurological conditions, such as stroke, brain injury, dementia, or neurodegenerative diseases like Parkinson's disease and Alzheimer's disease. Treatment typically involves rehabilitation and therapy focused on retraining the affected movements and compensating for any residual deficits.

Ideomotor apraxia is a neurological disorder that affects the ability to perform learned, purposeful movements in the absence of muscle weakness or paralysis. It results from damage to specific areas of the brain that are responsible for motor planning and execution.

In ideomotor apraxia, the person has difficulty translating an intention or idea into the appropriate movement. For example, if asked to pantomime using a toothbrush, they may not be able to recall and execute the correct sequence of movements required for this task, even though they understand what is being asked of them and have no problem moving their arm or hand.

This disorder can manifest as awkward, poorly coordinated, or incomplete movements, often with inconsistent errors. Ideomotor apraxia is typically seen following lesions to the left hemisphere of the brain, particularly in regions associated with language and motor function, such as Broca's area and the parietal lobe. Treatment usually involves occupational therapy and strategies to help compensate for the impaired motor skills.

Gait apraxia is a neurological disorder that affects an individual's ability to perform coordinated and complex movements required for walking, despite having the physical capability to do so. It is not caused by weakness or sensory loss, but rather by damage to the brain areas responsible for motor planning and execution, particularly in the frontal lobes.

Gait apraxia is characterized by a wide-based, hesitant, and unsteady gait pattern. Individuals with this condition may have difficulty initiating walking, changing direction, or adjusting their stride length and speed. They may also exhibit symptoms such as freezing of gait, where they are unable to move their feet forward despite intending to walk.

This disorder is often associated with various neurological conditions, including cerebrovascular accidents (strokes), degenerative diseases such as Parkinson's disease and multiple sclerosis, traumatic brain injuries, and infections of the central nervous system. Treatment typically involves physical therapy, gait training, and the use of assistive devices to improve mobility and safety.

Speech disorders refer to a group of conditions in which a person has difficulty producing or articulating sounds, words, or sentences in a way that is understandable to others. These disorders can be caused by various factors such as developmental delays, neurological conditions, hearing loss, structural abnormalities, or emotional issues.

Speech disorders may include difficulties with:

* Articulation: the ability to produce sounds correctly and clearly.
* Phonology: the sound system of language, including the rules that govern how sounds are combined and used in words.
* Fluency: the smoothness and flow of speech, including issues such as stuttering or cluttering.
* Voice: the quality, pitch, and volume of the spoken voice.
* Resonance: the way sound is produced and carried through the vocal tract, which can affect the clarity and quality of speech.

Speech disorders can impact a person's ability to communicate effectively, leading to difficulties in social situations, academic performance, and even employment opportunities. Speech-language pathologists are trained to evaluate and treat speech disorders using various evidence-based techniques and interventions.

Aphasia is a medical condition that affects a person's ability to communicate. It is caused by damage to the language areas of the brain, most commonly as a result of a stroke or head injury. Aphasia can affect both spoken and written language, making it difficult for individuals to express their thoughts, understand speech, read, or write.

There are several types of aphasia, including:

1. Expressive aphasia (also called Broca's aphasia): This type of aphasia affects a person's ability to speak and write clearly. Individuals with expressive aphasia know what they want to say but have difficulty forming the words or sentences to communicate their thoughts.
2. Receptive aphasia (also called Wernicke's aphasia): This type of aphasia affects a person's ability to understand spoken or written language. Individuals with receptive aphasia may struggle to follow conversations, comprehend written texts, or make sense of the words they hear or read.
3. Global aphasia: This is the most severe form of aphasia and results from extensive damage to the language areas of the brain. People with global aphasia have significant impairments in both their ability to express themselves and understand language.
4. Anomic aphasia: This type of aphasia affects a person's ability to recall the names of objects, people, or places. Individuals with anomic aphasia can speak in complete sentences but often struggle to find the right words to convey their thoughts.

Treatment for aphasia typically involves speech and language therapy, which aims to help individuals regain as much communication ability as possible. The success of treatment depends on various factors, such as the severity and location of the brain injury, the individual's motivation and effort, and the availability of support from family members and caregivers.

Ocular motility disorders refer to a group of conditions that affect the movement of the eyes. These disorders can result from nerve damage, muscle dysfunction, or brain injuries. They can cause abnormal eye alignment, limited range of motion, and difficulty coordinating eye movements. Common symptoms include double vision, blurry vision, strabismus (crossed eyes), nystagmus (involuntary eye movement), and difficulty tracking moving objects. Ocular motility disorders can be congenital or acquired and may require medical intervention to correct or manage the condition.

Agraphia is a neurological disorder that affects the ability to write, either by hand or through mechanical means like typing. It is often caused by damage to specific areas of the brain involved in language and writing skills, such as the left parietal lobe. Agraphia can manifest as difficulty with spelling, forming letters or words, organizing thoughts on paper, or expressing ideas in writing. Depending on the severity and location of the brain injury, agraphia may occur in isolation or alongside other language or cognitive impairments.

In a medical context, "gestures" are not typically defined as they are a part of communication and behavior rather than specific medical terminology. However, in the field of physical therapy or rehabilitation, gestures may refer to purposeful movements made with the hands, arms, or body to express ideas or commands.

In neurology or neuropsychology, abnormal gestures may be a symptom of certain conditions such as apraxia, where patients have difficulty performing learned, purposeful movements despite having the physical ability to do so. In this context, "gestures" would refer to specific motor behaviors that are impaired due to brain damage or dysfunction.

Thalamic diseases refer to conditions that affect the thalamus, which is a part of the brain that acts as a relay station for sensory and motor signals to the cerebral cortex. The thalamus plays a crucial role in regulating consciousness, sleep, and alertness. Thalamic diseases can cause a variety of symptoms depending on the specific area of the thalamus that is affected. These symptoms may include sensory disturbances, motor impairment, cognitive changes, and altered levels of consciousness. Examples of thalamic diseases include stroke, tumors, multiple sclerosis, infections, and degenerative disorders such as dementia and Parkinson's disease. Treatment for thalamic diseases depends on the underlying cause and may include medications, surgery, or rehabilitation therapy.

Ataxia is a medical term that refers to a group of disorders affecting coordination, balance, and speech. It is characterized by a lack of muscle control during voluntary movements, causing unsteady or awkward movements, and often accompanied by tremors. Ataxia can affect various parts of the body, such as the limbs, trunk, eyes, and speech muscles. The condition can be congenital or acquired, and it can result from damage to the cerebellum, spinal cord, or sensory nerves. There are several types of ataxia, including hereditary ataxias, degenerative ataxias, cerebellar ataxias, and acquired ataxias, each with its own specific causes, symptoms, and prognosis. Treatment for ataxia typically focuses on managing symptoms and improving quality of life, as there is no cure for most forms of the disorder.

Hypoalbuminemia is a medical condition characterized by having lower than normal levels of albumin in the blood. Albumin is a type of protein produced by the liver, and it plays a crucial role in maintaining oncotic pressure (the force that keeps fluid inside blood vessels) and transporting various substances throughout the body.

A serum albumin level below 3.5 g/dL (grams per deciliter) is generally considered hypoalbuminemia, although some laboratories may define it as a level below 3.4 g/dL or even lower. This condition can be caused by various factors, including liver disease, malnutrition, kidney disease, inflammation, and protein-losing enteropathy (a disorder that causes excessive loss of protein in the gastrointestinal tract).

Hypoalbuminemia is often associated with poorer clinical outcomes in several medical conditions, such as increased risk of infection, longer hospital stays, and higher mortality rates. It's essential to identify and address the underlying cause of hypoalbuminemia for appropriate treatment and improved patient outcomes.

Basal ganglia diseases are a group of neurological disorders that affect the function of the basal ganglia, which are clusters of nerve cells located deep within the brain. The basal ganglia play a crucial role in controlling movement and coordination. When they are damaged or degenerate, it can result in various motor symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and difficulty with balance and walking.

Some examples of basal ganglia diseases include:

1. Parkinson's disease - a progressive disorder that affects movement due to the death of dopamine-producing cells in the basal ganglia.
2. Huntington's disease - an inherited neurodegenerative disorder that causes uncontrolled movements, emotional problems, and cognitive decline.
3. Dystonia - a movement disorder characterized by sustained or intermittent muscle contractions that cause twisting and repetitive movements or abnormal postures.
4. Wilson's disease - a rare genetic disorder that causes excessive copper accumulation in the liver and brain, leading to neurological and psychiatric symptoms.
5. Progressive supranuclear palsy (PSP) - a rare brain disorder that affects movement, gait, and balance, as well as speech and swallowing.
6. Corticobasal degeneration (CBD) - a rare neurological disorder characterized by progressive loss of nerve cells in the cerebral cortex and basal ganglia, leading to stiffness, rigidity, and difficulty with movement and coordination.

Treatment for basal ganglia diseases varies depending on the specific diagnosis and symptoms but may include medication, surgery, physical therapy, or a combination of these approaches.

Articulation disorders are speech sound disorders that involve difficulties producing sounds correctly and forming clear, understandable speech. These disorders can affect the way sounds are produced, the order in which they're pronounced, or both. Articulation disorders can be developmental, occurring as a child learns to speak, or acquired, resulting from injury, illness, or disease.

People with articulation disorders may have trouble pronouncing specific sounds (e.g., lisping), omitting sounds, substituting one sound for another, or distorting sounds. These issues can make it difficult for others to understand their speech and can lead to frustration, social difficulties, and communication challenges in daily life.

Speech-language pathologists typically diagnose and treat articulation disorders using various techniques, including auditory discrimination exercises, phonetic placement activities, and oral-motor exercises to improve muscle strength and control. Early intervention is essential for optimal treatment outcomes and to minimize the potential impact on a child's academic, social, and emotional development.

Stereognosis is a medical term that refers to the ability to identify and recognize the form, size, and texture of an object by using tactile (touch) sensation without visual or auditory input. It's a component of sensory perception that allows us to understand the three-dimensional shape and nature of objects through touch alone.

Loss or impairment of stereognosis can be a sign of neurological disorders, such as damage to the sensory cortex in the parietal lobe of the brain. Testing stereognosis is often part of a neurological examination to assess the functioning of the nervous system and the sense of touch.

Gait ataxia is a type of ataxia, which refers to a lack of coordination or stability, specifically involving walking or gait. It is characterized by an unsteady, uncoordinated, and typically wide-based gait pattern. This occurs due to dysfunction in the cerebellum or its connecting pathways, responsible for maintaining balance and coordinating muscle movements.

In gait ataxia, individuals often have difficulty with controlling the rhythm and pace of their steps, tend to veer or stagger off course, and may display a reeling or stumbling motion while walking. They might also have trouble performing rapid alternating movements like quickly tapping their foot or heel. These symptoms are usually worse when the person is tired or attempting to walk in the dark.

Gait ataxia can be caused by various underlying conditions, including degenerative neurological disorders (e.g., cerebellar atrophy, multiple sclerosis), stroke, brain injury, infection (e.g., alcoholism, HIV), or exposure to certain toxins. Proper diagnosis and identification of the underlying cause are essential for effective treatment and management of gait ataxia.

Cerebellar ataxia is a type of ataxia, which refers to a group of disorders that cause difficulties with coordination and movement. Cerebellar ataxia specifically involves the cerebellum, which is the part of the brain responsible for maintaining balance, coordinating muscle movements, and regulating speech and eye movements.

The symptoms of cerebellar ataxia may include:

* Unsteady gait or difficulty walking
* Poor coordination of limb movements
* Tremors or shakiness, especially in the hands
* Slurred or irregular speech
* Abnormal eye movements, such as nystagmus (rapid, involuntary movement of the eyes)
* Difficulty with fine motor tasks, such as writing or buttoning a shirt

Cerebellar ataxia can be caused by a variety of underlying conditions, including:

* Genetic disorders, such as spinocerebellar ataxia or Friedreich's ataxia
* Brain injury or trauma
* Stroke or brain hemorrhage
* Infections, such as meningitis or encephalitis
* Exposure to toxins, such as alcohol or certain medications
* Tumors or other growths in the brain

Treatment for cerebellar ataxia depends on the underlying cause. In some cases, there may be no cure, and treatment is focused on managing symptoms and improving quality of life. Physical therapy, occupational therapy, and speech therapy can help improve coordination, balance, and communication skills. Medications may also be used to treat specific symptoms, such as tremors or muscle spasticity. In some cases, surgery may be recommended to remove tumors or repair damage to the brain.

Speech production measurement is the quantitative analysis and assessment of various parameters and characteristics of spoken language, such as speech rate, intensity, duration, pitch, and articulation. These measurements can be used to diagnose and monitor speech disorders, evaluate the effectiveness of treatment, and conduct research in fields such as linguistics, psychology, and communication disorders. Speech production measurement tools may include specialized software, hardware, and techniques for recording, analyzing, and visualizing speech data.

Speech Therapy, also known as Speech-Language Pathology, is a medical field that focuses on the assessment, diagnosis, treatment, and prevention of communication and swallowing disorders in children and adults. These disorders may include speech sound production difficulties (articulation disorders or phonological processes disorders), language disorders (expressive and/or receptive language impairments), voice disorders, fluency disorders (stuttering), cognitive-communication disorders, and swallowing difficulties (dysphagia).

Speech therapists, who are also called speech-language pathologists (SLPs), work with clients to improve their communication abilities through various therapeutic techniques and exercises. They may also provide counseling and education to families and caregivers to help them support the client's communication development and management of the disorder.

Speech therapy services can be provided in a variety of settings, including hospitals, clinics, schools, private practices, and long-term care facilities. The specific goals and methods used in speech therapy will depend on the individual needs and abilities of each client.

Olivopontocerebellar atrophies (OPCA) are a group of rare, progressive neurodegenerative disorders that primarily affect the cerebellum, olive (inferior olivary nucleus), and pons in the brainstem. The condition is characterized by degeneration and atrophy of these specific areas, leading to various neurological symptoms.

The term "olivopontocerebellar atrophies" encompasses several subtypes, including:

1. Hereditary spastic paraplegia with cerebellar ataxia (SPG/ATA) - Autosomal dominant or recessive inheritance pattern.
2. Hereditary dentatorubral-pallidoluysian atrophy (DRPLA) - Autosomal dominant inheritance pattern.
3. Idiopathic OPCA - No known genetic cause, possibly related to environmental factors or spontaneous mutations.

Symptoms of olivopontocerebellar atrophies may include:

* Progressive cerebellar ataxia (gait and limb incoordination)
* Dysarthria (slurred speech)
* Oculomotor abnormalities (nystagmus, gaze palsy)
* Spasticity (stiffness and rigidity of muscles)
* Dysphagia (difficulty swallowing)
* Tremors or dystonia (involuntary muscle contractions)

Diagnosis typically involves a combination of clinical examination, neuroimaging studies (MRI), genetic testing, and exclusion of other possible causes. Currently, there is no cure for olivopontocerebellar atrophies, but supportive care can help manage symptoms and improve quality of life.

Neuropsychological tests are a type of psychological assessment that measures cognitive functions, such as attention, memory, language, problem-solving, and perception. These tests are used to help diagnose and understand the cognitive impact of neurological conditions, including dementia, traumatic brain injury, stroke, Parkinson's disease, and other disorders that affect the brain.

The tests are typically administered by a trained neuropsychologist and can take several hours to complete. They may involve paper-and-pencil tasks, computerized tasks, or interactive activities. The results of the tests are compared to normative data to help identify any areas of cognitive weakness or strength.

Neuropsychological testing can provide valuable information for treatment planning, rehabilitation, and assessing response to treatment. It can also be used in research to better understand the neural basis of cognition and the impact of neurological conditions on cognitive function.

Higher Nervous Activity (HNA) is a term used in neurology and psychology to refer to the complex functions of the nervous system that are associated with higher order cognitive processes, such as thinking, learning, memory, perception, and language. These functions are primarily mediated by the cerebral cortex and other associative areas of the brain, which are involved in integrating sensory information, planning and executing motor responses, and modulating emotional and social behavior.

HNA is often contrasted with lower nervous activity (LNA), which refers to more basic functions of the nervous system, such as reflexes and automatic responses that do not require conscious control or higher-order cognitive processing. HNA is thought to be unique to humans and some other animals, and is believed to have evolved to enable complex behaviors and adaptations to changing environments.

Disorders of HNA can result in a wide range of neurological and psychiatric symptoms, depending on the specific areas of the brain that are affected. These may include cognitive impairments, memory loss, language disorders, perceptual disturbances, emotional dysregulation, and motor deficits.

Agnosia is a medical term that refers to the inability to recognize or comprehend the meaning or significance of sensory stimuli, even though the specific senses themselves are intact. It is a higher-level cognitive disorder, caused by damage to certain areas of the brain that are responsible for processing and interpreting information from our senses.

There are different types of agnosia, depending on which sense is affected:

* Visual agnosia: The inability to recognize or identify objects, faces, or shapes based on visual input.
* Auditory agnosia: The inability to understand spoken language or recognize sounds, even though hearing is intact.
* Tactile agnosia: The inability to recognize objects by touch, despite normal tactile sensation.
* Olfactory and gustatory agnosia: The inability to identify smells or tastes, respectively, even though the senses of smell and taste are functioning normally.

Agnosia can result from various causes, including stroke, brain injury, infection, degenerative diseases, or tumors that damage specific areas of the brain involved in sensory processing and interpretation. Treatment for agnosia typically focuses on rehabilitation and compensation strategies to help individuals adapt to their deficits and improve their quality of life.
