Clinical Trial
Dynamic assessment of abnormalities in central pain transmission and modulation in tension-type headache sufferers.
To examine and compare central pain processing and modulation in young tension-type headache sufferers with that of matched healthy controls using an induced headache "challenge" paradigm. ⋯ These results confirm previous findings indicating abnormally high pericranial muscle tenderness in young tension headache sufferers even in the headache-free state. In addition, the results suggest that the development of headaches following noxious stimulation is more strongly related to headache proneness and associated abnormalities in central pain transmission or modulation (indexed by pericranial muscle tenderness and exteroceptive suppression responses) than muscle strain induced by jaw clenching.

A population-based epidemiological survey of migraine without aura and migraine with aura completed by mailed questionnaire in Hungary. The diagnosis and classification of migraine was according to the criteria of the International Headache Society. ⋯ Sixty-seven percent of these people experienced some kind of headache during their lives. The 1-year prevalence of migraine without aura was 7.6% (the female/male ratio was 3:1), while the 1-year prevalence of migraine with aura was 2% (female/male ratio was 2:1). Most migraineurs experienced headache attacks 1 to 4 times monthly, which lasted 24 hours. The most characteristic accompanying signs were nausea and phonophobia. Stress, sleep deprivation, hot weather, and fasting were the most common precipitating factors of a migraine attack. In the migraine with aura group, the most common aura was a visual disturbance. Only 43% of migraineurs had ever consulted a physician for headache, and only 15% of patients had missed work or school because of a migraine attack in the previous year. Most of the patients suffering from migraine without aura were between 20 and 40 years old, while migraineurs with aura were over 40 years old. According to this investigation, the prevalence of migraine was not lower than in Western countries.
