Symptomatic and nonsymptomatic headaches in a general population.

Area of Science:

• Neurology
• Epidemiology
• Public Health

Background:

• Headache disorders are common but vary in prevalence.
• Understanding the epidemiology of specific headache types is crucial for public health.
• Previous studies have not comprehensively assessed lifetime prevalence across diverse headache classifications in a general population.

Purpose of the Study:

• To determine the lifetime prevalence of various headache disorders in a representative adult population.
• To classify headaches using the International Headache Society criteria.
• To explore associations between headache types, demographics, and other health factors.

Main Methods:

• Cross-sectional epidemiologic survey.
• Inclusion of a representative general population sample aged 25-64 years.
• Clinical interviews and physical/neurologic examinations based on International Headache Society criteria.

Main Results:

• Hangover headache (72%) and fever headache (63%) were highly prevalent.
• Idiopathic stabbing headache (2%), external compression headache (4%), and cold stimulus headache (15%) were also documented.
• Certain headaches, including external compression and fever headache, showed a significant female predominance. Headaches associated with structural lesions were rare.
• Migraineurs had higher rates of symptomatic headaches, while tension-type headache sufferers predominantly experienced hangover headaches.
• No association was found between headache disorders and abnormal blood chemistry or hypertension, except for higher diastolic blood pressure in women with migraine.

Conclusions:

• Prevalence of specific headache disorders varies significantly, with common types like hangover and fever headaches being widespread.
• Certain headache types exhibit gender-based prevalence differences.
• While most headaches are benign, specific associations like higher blood pressure in women with migraine warrant further investigation.
