Spinocerebellar ataxia

Spinocerebellar ataxia (pronunciation: /ˌspaɪnoʊˌsɛrəˈbɛlər əˈtæksiə/) is a term referring to a group of hereditary ataxias that are characterized by degenerative changes in the part of the brain related to the control of movement (cerebellum) and sometimes in the spinal cord.

Etymology

The term "spinocerebellar" is derived from the Latin words 'spina' meaning 'spine', 'cerebellum' meaning 'little brain', and 'ataxia' from the Greek 'a-' (not) and '-taxis' (order), thus meaning 'lack of order'.

Symptoms

Symptoms of spinocerebellar ataxia can vary among affected individuals and by the type of ataxia. Some common symptoms include problems with coordination and balance (ataxia), abnormal eye movements, and problems with speech (dysarthria).

Types

There are several types of spinocerebellar ataxia, each with its own unique set of symptoms and genetic causes. These include SCA1, SCA2, SCA3, and so on.

Diagnosis

Diagnosis of spinocerebellar ataxia is based on clinical symptoms, a family history of ataxia, and genetic testing. Neuroimaging, such as MRI, can also be used to identify changes in the cerebellum and spinal cord.

Treatment

There is currently no cure for spinocerebellar ataxia. Treatment is focused on managing symptoms and might include physical therapy, speech therapy, and medications to control spasticity and other symptoms.
