Cerebellar infarction occurs when blood flow to the cerebellum, a part of the brain responsible for coordination and balance, is blocked. This blockage can result from a blood clot or a narrowed artery, leading to tissue damage and loss of function in the affected area. Symptoms may include dizziness, difficulty walking, and problems with coordination. Diagnosis typically involves imaging tests like CT scans or MRI to visualize the brain and identify the infarction. Treatment often focuses on restoring blood flow and may include medications, rehabilitation, and lifestyle changes to prevent future strokes.
