Basilar-type migraine is classified as a recognizable type of migraine disorder and is categorized under migraine with aura, sharing many similar symptoms.
This type of migraine can often occur alongside sensory auras and can be mistaken for hemiplegic migraine due to them both having many symptoms in common.
Basilar-type Migraine Symptoms
Basilar-type migraine episodes can be identified by sufferers experiencing extreme dizziness, major changes to vision or double vision, vertigo and lack of coordination. These symptoms can last for any period of time but in most circumstances end after approximately one hour.
They are then followed by head pain which, unlike other migraine types, is often concentrated in the base of the skull. The head pain associated with basilar-type migraines may not be a throbbing pain that is associated with other migraine types. It is also common for sufferers to experience problems after the migraine attack such as difficulty coordinating muscles or dizziness.

- Partial paralysis
- Numbness/tingling sensation on both sides of the body
