Headache in Sturge-Weber syndrome

Area of Science:

• Neurology
• Genetics
• Pediatrics

Background:

• Sturge-Weber syndrome is a rare congenital disorder.
• Headaches, including migraine, are common in patients with vascular malformations and epilepsy.
• The prevalence of migraine in Sturge-Weber syndrome has not been well-established.

Purpose of the Study:

• To determine the prevalence and characteristics of migraine headaches in individuals with Sturge-Weber syndrome.
• To compare migraine prevalence in Sturge-Weber syndrome to the general population.
• To explore potential associations between migraine and neurological deficits in this population.

Main Methods:

• A questionnaire was distributed to 500 members of the Sturge-Weber Foundation.
• Headache prevalence and type were assessed using International Headache Society (IHS) criteria.
• Data from 71 patients (average age 15 years, 1:1 sex ratio) were analyzed.

Main Results:

• Migraine headaches meeting IHS criteria occurred in 28% of Sturge-Weber syndrome patients, significantly higher than the general population (5-17%).
• Migraine prevalence was notably high in children under 10 (31%) compared to the general population (5%), with an earlier age of onset.
• Neurological deficits were present in 58% of patients experiencing migraine.

Conclusions:

• Migraine headache is more prevalent in Sturge-Weber syndrome than in the general population.
• The findings suggest a potential shared pathophysiological mechanism between migraine in Sturge-Weber syndrome, epilepsy, and other vascular malformations.
• Early-onset migraine is a significant feature in children with Sturge-Weber syndrome.
