Superior cerebellar artery strokes most often present with headache, gait ataxia, dysarthria.Different types of cerebellar strokes can be defined by their vascular supply, though physical manifestations can frequently overlap or be atypical.The cerebellum is supplied by three major arteries: the superior cerebellar artery, the anterior inferior cerebellar artery, and the posterior inferior cerebellar artery.Less commonly, vertebral artery dissections will lead to cerebellar strokes which can be seen in younger patients.
