cerebellar ataxia, CA, CCA A two-year-old Arabian horse with cerebellar abiotrophy, showing stiff awkward gait, and upper range of unnatural head bob. Though this horse had a relatively mild case, it could never be ridden.
Wobbler disease or wobbler's syndrome is a broad category of cervical disorders in the horse, including the conditions listed above, as well as equine wobbles anemia and cervical vertebral myelopathy, spinal cord compression (sometimes referred to colloquially among horse owners as "cervical arthritis" due to the arthritis that accumulates in facets).
Equine EPM is caused by the parasites that exhibit SAG1, SAG5, and SAG6. SAG1 and SAG5 are responsible for the majority of EPM cases in horses. Horses produce antibodies to these surface antigens. Serum antibody testing is available that measures levels of these antibodies in the blood of horses, which is helpful in diagnosing EPM in an ataxic ...
As a stand-alone condition, "ataxia is a degenerative disease of the nervous system," explains Andrew Rosen, chief executive officer of the National Ataxia Foundation. There are many types ...
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.
It is associated with cerebellar ataxia, [1] [2] when the cerebellum has been damaged and does not function to its fullest ability. Lesions to the cerebellum can cause dyssynergia, dysmetria, dysdiadochokinesia, dysarthria, and ataxia of stance and gait. [3] Dyschronometria can result from autosomal dominant cerebellar ataxia (ADCA). [4]
Grass sickness, alternatively termed equine dysautonomia, is a rare but predominantly fatal illness in horses. Grass sickness may affect all types of horse, pony and donkey , and has affected some well known horses including the thoroughbred stallions Dubai Millennium , Moorestyle and Mister Baileys .
As a result of this gait impairment, falling is a concern in patients with ataxia. [3] Truncal ataxia affects the muscles closer to the body such as the trunk, shoulder girdle and hip girdle. It is involved in gait stability. [3] Truncal ataxia is different from appendicular ataxia. Appendicular ataxia affects the movements of the arms and legs.
