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.
Locomotor ataxia is the inability to precisely control one's own bodily movements. [1] Disease
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 ]
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 ...
Spinocerebellar ataxia (SCA) is a progressive, ... akinesia (loss of normal motor function, resulting in impaired muscle movement) CAG repeat, 5q SCA13
According to the research article cited above, motor control is a learning process that utilizes APPGs. [8] Disruption of APPGs is possibly the cause of ataxia and dysmetria and upon identification of the motor primitives, clinicians may be able to isolate the specific areas responsible for the cerebellar problems. [8]
[3] [4] Ataxia (lack of coordination) is a prominent symptom early in the disease course. The trigeminal nerve ganglion is also commonly affected leading to facial numbness. Motor nerves are usually not affected however some cases do have mild motor involvement in the form of weakness.
