[Importance of predisposing factors and personality characteristics in cluster headache patients (author's transl)].

Predisposing factors and concomitant diseases were examined in cluster headache patients. A positive or negative correlation to a particular disease, e.g. gastrointestinal ulcerative disease, could not be showen. Factors indicating a genetic predisposition could also not be found. In the Freiburg Personality Inventory cluster and migraine patients had an essentially normal profile; however, both groups evidenced a tendency towards psychosomatic reactions.
