Common basilar artery migraine symptoms include cold feet and hands, light and sound sensitivity, nausea and vomiting, according to WebMD. People with a basilar artery migraine typically experience a minimum of two of the following symptoms: slurred speech, loss of balance, hearing impairments, body tingling and double vision. Dizziness, loss of consciousness, temporary blindness and confusion may also occur.
The migraine usually starts on one side of the head before spreading and intensifying, explains WebMD. The pain is typically pulsing or throbbing and each aura symptom can last up to about one hour. An aura symptom may develop gradually over a few minutes, and then additional symptoms will develop in short succession. The headache develops either during an aura or right after.
A person who has a minimum of two attacks with at least two auras each is diagnosed as having a basilar artery migraine, advises WebMD. A proper medical diagnosis is important because basilar artery migraine symptoms are common to other serious health conditions; meningitis, seizure disorders and brain lesions, to name a few. A hemiplegic migraine is sometimes confused with a basilar artery migraine, as the two share common symptoms. However, a weakening of motor skills occurs with a hemiplegic migraine but not with a basilar artery migraine.
A migraine specialist is best suited to diagnose the condition, according to WebMD. To eliminate other conditions, a doctor may order a lumbar puncture, magnetic resonance imaging test or computerized tomography scan.
