Headache associated with sexual activity is an idiopathic headache disorder and regarded to be a vascular headache but no pathophysiological studies have been performed to date to elucidate the underlying mechanisms. We investigated 12 patients with the explosive type of sexual headache according to the criteria of the International Headache Society during a headache-free state by means of acetazolamide test and of stress Doppler sonography. Twelve age-matched migraine patients and 14 healthy subjects served as control groups. Changes of blood pressure, cerebral blood flow velocity (CBFV), and pulsatility index (PI) were evaluated. Patients with sexual headache showed a significantly higher increase of blood pressure during standardized physical exercise as compared to healthy subjects and migraine patients. Changes of CBFV by physical exercise were not different between the three examination groups. After 1g acetazolamide, CBFV showed a significantly higher increase in patients with sexual headache (plus 66%+/-16%) than in healthy subjects (plus 46%+/-18%), and PI showed a significantly lower decrease as compared to healthy subjects and migraine patients. These data suggest that in patients with sexual headache the metabolic rather than the myogenic component of the cerebral vasoneuronal coupling is impaired.

Cognitive processing in headache associated with sexual Cognitive processing as measured by event-related potentials (ERP) in patients suffering from the explosive subtype of headache associated with sexual activity (HSA type 2) was investigated. Visual ERP were measured in 24 patients with HSA type 2 outside the headache period. The differences of the first and the second part of measurement were evaluated separately to determine the amount of cognitive habituation. Twenty-four sex- and age-matched healthy subjects and 24 patients with migraine without aura served as controls. A missing increase of P3 latency during the second part of the measurement was found in 79% of patients with HSA type 2 and in 75% with migraine, but only in 17% of the healthy controls (P < 0.001). The P3 amplitude was increased during the second part in 71% of patients with HSA type 2 and in 79% with migraine, but only in 33% of the healthy controls (P = 0.02). Mean P3 latency was decreased and mean P3 amplitude was increased during the second part of the measurement in HSA type 2 and in migraine but not in the healthy control group. Patients with HSA type 2 have a loss of cognitive habituation as measured by ERP. This specific information processing is very similar to that in migraine observed in previous studies.

Headache associated with sexual activity (HASA) is a common and benign form of primary headache in most cases and has a favorable prognosis. However, even a single episode of primary headache is a cause for an immediate and thorough examination to rule out the secondary nature of cephalgia. The paper considers the pathogenesis, differential diagnosis, and principles in the treatment of patients with this disease.
