Acephalgic migraine

Acephalgic migraine (also called migraine aura without headache, amigrainous migraine, isolated visual migraine, and optical migraine) is a neurological syndrome. It is a relatively uncommon variant of migraine in which the patient may experience some migraine symptoms such as aura, nausea, photophobia, and hemiparesis, but does not experience headache.^[1] It is generally classified as an event fulfilling the conditions of migraine with aura with no (or minimal) headache.^[2]^[3] It is sometimes distinguished from visual-only migraine aura without headache, also called ocular migraine.^[4]
