Ataxia (from Greek α- [a negative prefix] + -τάξις [order] = "lack of order") is a neurological sign consisting of lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, and abnormalities in eye movements, that indicates dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum.
Ataxia usually goes away without any treatment. In cases where an underlying cause is identified, medical treatment may be needed. In extremely rare cases, patients can have continuing and disabling symptoms. Treatment includes corticosteroids, intravenous immunoglobulin, or plasma exchange therapy. Drug treatment to improve muscle coordination ...
The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present. Clinical findings include ataxia, sensory neuropathy, and absence of the vestibulo-ocular reflex. The syndrome was initially described in 2004. [1] In 2019, the cause was identified as biallelic pentanucleotide expansion in the ...
This form of ataxia "can have many causes including cancer, autoimmune diseases, degenerative brain conditions and a large number of genetic diseases." Hereditary ataxias, such as Friedreich’s ...
Cerebellar ataxia is a form of ataxia originating in the cerebellum. [1] Non-progressive congenital ataxia (NPCA) is a classical presentation of cerebral ataxias. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. [ 2 ]
The clinical hallmark of megavitamin-B 6 syndrome is ataxia due to sensory polyneuropathy. Blood tests are performed to rule out other causes and to confirm an elevated level of vitamin B 6 with an absence of hypophosphatasia .
Friedreich's ataxia (FRDA) is a rare, inherited, autosomal recessive neurodegenerative disorder that primarily affects the nervous system, causing progressive damage to the spinal cord, peripheral nerves, and cerebellum, leading to impaired muscle coordination . The condition typically manifests in childhood or adolescence, with initial ...
The damage to the cerebellum or the inferior cerebellar peduncle can cause ataxia. Damage to the hypothalamospinal fibers disrupts sympathetic nervous system relay and produces symptoms that are similar to the symptoms caused by Horner's syndrome – such as miosis, anhidrosis and partial ptosis.
