Is HSP an Ataxia?
No. The group of disorders known as Ataxias (such as Friedreichs Ataxia) are spino-cerebellar disorders in which there is a disturbance either in the part of the brain known as the cerebellum or in the connections to it. HSP does not involve the cerebellum. Ataxias can be hereditary or sporadic. The term “ataxia” means without coordination, and can also refer to a symptom in which there is a lack of muscle control resulting in a jerky or unsteady movement. People with HSP may have in coordination as a symptom. This does not mean they have Ataxia.
