A Misbehaving Limb

Abstract

This case provides the background for a discussion of post-stroke movement disorders. Hyperkinetic movement disorders are rare after cerebral infarction, the most common being chorea and ballismus. The role of the basal ganglia is more easily understood if one studies the clinical manifestations of neurological disorders of the basal ganglia. Strategic lesions of the basal ganglia and occasionally other brain structures, which may be vascular, structural, infective, traumatic or hypoxic in origin, can all result in secondary movement disorders. However, movement disorders of a vascular origin differ in their clinical presentation, natural history, prognosis and treatment. Haemorrhagic or ischaemic strokes may account for approximately 25 % of secondary movement disorders and can occur immediately after a stroke or have a delayed presentation.
