Spinocerebellar Ataxia (SCA) is a group of inherited disorders that affect coordination and balance. It occurs due to degeneration of specific areas in the brain, particularly the cerebellum, which is responsible for motor control. Symptoms often include unsteady gait, difficulty with fine motor tasks, and problems with speech. There are several types of SCA, each caused by different genetic mutations. The onset and severity of symptoms can vary widely among individuals. Diagnosis typically involves clinical evaluation, genetic testing, and imaging studies to assess brain function and structure. Treatment focuses on managing symptoms and improving quality of life.
