[Non-alimentary trigger factors of migraine and tension-type headache]

Abstract

Based on an overview of the literature, this contribution critically discusses the importance of non-alimentary trigger factors of migraine and tension-type headache. Menstruation, environmental factors, psychological effects as well as sleep disorders and fatigue are mentioned most frequently. According to controlled studies, menstruation is indubitably associated with an increased risk of headache. Although a correlation between specific meteorological parameters and the appearance of headaches was established in some patients, the subjective observations of the patients did not however correlate with the objective weather data. Sensory stimuli function as triggers particularly for migraine with aura. Psychological factors, especially stress and everyday pressures, have been confirmed as trigger factors, but further prospective trials addressing this issue would be advantageous. Additional studies are also needed to elucidate the significance of sleep (disorders) and fatigue since their importance as triggers or symptoms of a headache attack has not been conclusively determined.
