Nocturnal headache: systemic arterial pressure and heart rate during sleep.
Cephalalgia (Impact Factor: 4.89). 09/1983; 3 Suppl 1:54-7. DOI: 10.1177/03331024830030S106
In order to evaluate autonomic nervous system changes occurring before nocturnal headache attacks, we studied three subjects (one male, two females) suffering from chronic migraine. All three patients underwent a nocturnal polygraphic recording including continuous monitoring of systemic arterial pressure and heart rate. Two subjects showed increases and irregularities of arterial pressure before awakening with headache. These changes began during N-REM sleep and lasted during REM sleep preceding the awakening with headache. Heart rate did not change before the attacks. These findings do not support the hypothesis that autonomic instability during REM sleep represents the precipitating factor of the attacks.

ABSTRACT: In a cross-sectional epidemiological study of headache disorders information on precipitating factors, age at onset, influence of menstruation and pregnancy and use of oral contraceptives was collected. The presence of migraine and tension-type headache was ascertained by a clinical interview and examination using the operational diagnostic criteria of the International Headache Society. The prevalence of migraine and tension-type headache was also analysed in relation to variables of lifestyle: physical activity, smoking, consumption of coffee, alcohol intake and sleep pattern. In both migraine and tension-type headache, the most conspicuous precipitating factor was stress and mental tension. Other common precipitants were alcohol, weather changes and menstruation. Disappearance or substantial improvement of the headache during pregnancy was more frequent in migraineurs than in tension-type headache sufferers. The age at onset of both migraine and tension-type headache differs between men and women. Female hormones may be an important factor responsible for the sex difference of headache disorders. The level of physical activity showed no association with migraine, but a significantly higher prevalence of tension-type headache in men with exclusively sedentary activity emerged. Smoking, coffee and alcohol consumption showed no significant associations with the headache disorders. Sleep pattern was significantly associated with migraine and tension-type headache in both univariate and multivariate analyses. In conclusion, migraine and tension-type headache seem to be different with regard to a number of endogenous and exogenous factors.Pain 05/1993; 53(1):65-72.

Article: Hypothlamus, sleep and headaches[Show abstract] [Hide abstract]
ABSTRACT: The hypothalamus is a key neural region in the regulation of sleep, its anterior part implicated in sleep facilitation, while the posterior hypothalamus acts in a balanced way to maintain wakefulness. The hypothalamus forms part of the so-called central autonomic network, regulating body homeostasis and controlling pain. To this effect, it is strongly wired to more rostral and caudal areas, in particular the brainstem periaqueductal grey, the locus coeruleus and the median raphe nuclei, all involved in sleep mechanisms and also in the descending control of pain perception. The hypothalamus, especially its posterior regions, becomes activated during attacks of the so-called trigeminal autonomic cephalalgias (TACs), while brainstem, especially dorsal pontine, activity shows up during migraine attacks. The hypothalamus and interconnected brainstem areas likely represent the neural sites responsible for the chronobiological features of some headaches, in particular the sleep-related attacks typical of the TACs, migraines and the hypnic headaches.Neurological Sciences 06/2006; 27 Suppl 2(S2):S138-43.
