In the new classification of migraine, Subtype 1.6 indicates complications of migraine. This would include all of the permanent defects discussed in this section.

Focal symptoms and signs of the aura may persist beyond a headache phase. In the previous classification, this was termed complicated migraine. It is now defined by the IHS classification with two labels with increased specificity. If the aura lasts for longer than one hour but less than one week, the term migraine with prolonged aura is applied. If the signs persist for more than one week or a neuroimaging procedure demonstrates a stroke, a migrainous infarction has occurred. As pointed out previously, mid or later life the aura may not be followed by headache and has been termed migraine accompagnée or migraine associée. Migraine with aura (classic) in early reports was sometimes referred to as "ophthalmic migraine" (to be differentiated from ophthalmoplegic migraine, a subtype of migraine with aura). Migraine with aura is further reviewed under the headings: Cerebral, Ophthalmoplegic, Retinal, Basilar, and Other Varieties.

Cerebral

A variety of cerebral symptoms may occur in migraine with aura, including motor, visual, and other sensory defects. As pointed out previously, if the aura lasts for more than one hour , but less than one week, the term migraine with prolonged aura is applied. However, if the signs persist for more than one week, or a neuroimaging procedure shows a stroke the term used is migrainous infarction.
