Basilar artery migraine. A review of 30 cases
Abstract:
Thirty patients with basilar artery migraine were followed up for a period of six months to three years. The mean age of onset was 7 years. The patients were seen with recurrent transient attacks of neurological disturbances localized to the vertebrobasilar arterial tree. Attacks often included pulsatile cephalagia. A history of migraine was present in 86% of the families studied. The majority of family members with migraine were female and on the maternal side. Permanent neurological residua developed in only one patient. There was a tendency for attacks to be more severe with an older age of onset. Basilar artery migraine is a migraine variant that may affect children from late infancy through adolescence.
Insights
Basilar artery migraine, a variant affecting children, involves transient neurological issues and headaches. Most patients had a family history, with attacks potentially worsening with age.
Area of Science:
- Neurology
- Pediatrics
- Genetics
Background:
- Basilar artery migraine is a rare migraine variant.
- It primarily affects children and adolescents.
- Characterized by transient neurological symptoms originating from the vertebrobasilar system.
Purpose of the Study:
- To describe the clinical characteristics and familial aggregation of basilar artery migraine.
- To evaluate the long-term outcomes in a cohort of affected children.
Main Methods:
- Retrospective follow-up study of 30 patients diagnosed with basilar artery migraine.
- Data collected included age of onset, attack characteristics, family history, and neurological outcomes.
- Follow-up duration ranged from six months to three years.
Main Results:
- The mean age of onset was 7 years.
- Recurrent transient neurological disturbances localized to the vertebrobasilar arterial tree were observed.
- Pulsatile headaches (cephalalgia) were a common feature.
- A significant family history of migraine (86%) was noted, predominantly on the maternal side and in females.
- Older age of onset correlated with more severe attacks.
- Only one patient experienced permanent neurological deficits.
Conclusions:
- Basilar artery migraine is a distinct migraine variant with a strong familial component.
- It typically presents in childhood with transient neurological symptoms and headaches.
- The prognosis is generally favorable, with a low risk of permanent neurological sequelae.
