Hypoglycemic hemiplegia: two cases and a clinical review.

Hypoglycemic hemiplegia mimics cerebrovascular disease. Two patients are reported who experienced multiple attacks of transient hemiplegia associated with hypoglycemia and who were initially diagnosed as having transient ischemic attacks. In both, angiography was normal and the attacks resolved with reduction of insulin dose. Recognition of hypoglycemia as the cause of transient hemiplegia is important, often obviating the need for cerebrovascular evaluation.
