Cerebellar circuitry is important to controlling and modifying motor activity. It
conducts the coordination and correction of errors in muscle contractions during
active movements. Therefore, cerebrovascular lesions of the cerebellum or its
pathways can cause diverse movement disorders, such as action tremor, Holmes'
tremor, palatal tremor, asterixis, and dystonia. The pathophysiology of abnormal
movements after stroke remains poorly understood. However, due to the current
advances in functional neuroimaging, it has recently been described as changes in
functional brain networks. This review describes the clinical features and
pathophysiological mechanisms in different types of movement disorders following
cerebrovascular lesions in the cerebellar circuits.
