Movement disorder, as a presentation of an acute or chronic cerebrovascular disease (CVD) occur in less than five percent of CVD cases. Although a rare presentation of CVDs, stroke is a common etiology of secondary movement disorder. Hemichorea is particularly prevalent following stroke. The objectives of this report are to (1) present nine cases of sudden-onset hyperkinetic movement disorders manifested in acute and chronic stroke patients (2) emphasize the importance of early diagnosis by clinical signs and symptoms identified through computed tomography (CT) and magnetic resonance imaging (MRI), and (3) determine the different anatomic locations involved in this disorder. Hemichorea is the most common hyperkinetic movement disorder seen after stroke with a predilection in older age. It demonstrated that deep vascular lesions had a greater probability of developing movement disorder. Hemichorea-hemiballismus with abrupt onset should be approached as an acute stroke until other potential causes are ruled out. The exact pathophysiology of these abnormal movements remains unclear, although some theories propose dysfunction within the motor circuitry pathway. While many cases resolve spontaneously, medical or surgical interventions may be necessary to manage symptoms, potentially influencing long-term outcomes.
