Amigrainous 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. Amigrainous migraine is also referred to as Acephalgic migraine or optical migraine or scintillating scotoma.
Sufferers of Amigrainous migraine are more likely than the general population to develop classical migraine with headache.
The prevention and treatment of Amigrainous migraine is broadly the same as for classical migraine. However, because of the absence of "headache," diagnosis of Amigrainous migraine is apt to be significantly delayed and the risk of misdiagnosis significantly increased.
