Cerebellar ataxia is a neurological condition characterized by a lack of muscle coordination and balance. It occurs when the cerebellum, a part of the brain responsible for coordinating movement, is damaged or not functioning properly. Symptoms may include unsteady gait, difficulty with fine motor tasks, and problems with speech. The condition can result from various causes, including genetic disorders, stroke, or chronic alcohol abuse. Diagnosis typically involves a physical examination, medical history, and imaging tests like MRI to assess brain function. Treatment focuses on managing symptoms and may include physical therapy and medications.
