What is Spinocerebellar ataxia

Spinocerebellar ataxia (SCA) is a group of genetic disorders that primarily affect the coordination and balance of an individual. It is characterized by the progressive degeneration of the cerebellum, a region of the brain responsible for coordinating voluntary movements.

SCA is inherited in an autosomal dominant manner, meaning that an affected individual has a 50% chance of passing the condition on to their children. There are multiple types of SCA, each caused by a different genetic mutation. The symptoms and age of onset can vary depending on the specific type.

Common symptoms of SCA include: unsteady gait, difficulty with coordination, slurred speech, muscle weakness, and tremors. As the disease progresses, individuals may experience difficulties with daily activities such as eating, writing, and speaking.

Currently, there is no cure for SCA, and treatment focuses on managing symptoms and improving quality of life. Physical therapy, assistive devices, and medications may be used to alleviate symptoms and enhance mobility. Genetic counseling is also recommended for individuals with a family history of SCA.
