The most recent headache classification recognizes migrainous infarction in patients with migraine with aura. Uncommon forms of migraine have a less clear relation to stroke. REVIEW SUMMARY Ophthalmoplegic migraine is very rare, affecting mostly the third cranial nerve, and is a diagnosis of exclusion. Retinal migraine is also uncommon and may mimic embolic retinal infarcts. Basilar migraine very rarely leads to permanent deficits. Familial hemiplegic migraine is probably genetically related to cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. A prominent feature of mitochondrial myopathy, en-cephalopathy, lactic acidosis and stroke-like episodes is migrainous headache. CONCLUSIONS Uncommon subtypes of migraine are occasionally encountered by the clinician. Other causes of neurologic deficits should first be sought. In the presence of a positive family history, genetic testing is available. © 1999 Lippincott Williams & Wilkins, Inc.
