Acephalgic migraine is a neurological syndrome. It is a variant of migraine in which the patient may experience aura, nausea, photophobia, hemiparesis and other migraine symptoms but does not experience headache. Acephalgic migraine is also referred to as amigrainous migraine or optical migraine or scintillating scotoma.
Sufferers of acephalgic migraine are more likely than the general population to develop classical migraine with headache.
The prevention and treatment of acephalgic migraine is broadly the same as for classical migraine. However, because of the absence of "headache," diagnosis of acephalgic migraine is apt to be significantly delayed and the risk of misdiagnosis significantly increased.
