  • Title: The physiological stress response and the role of cognitive coping in migraine patients and non-headache controls.
    Author: Kröner-Herwig B, Fritsche G, Brauer H.
    Journal: J Psychosom Res; 1993 Jul; 37(5):467-80. PubMed ID: 8350289.
    Abstract:
    Our study investigated physiological response specificity and cognitive coping in migrainous patients during an achievement task situation. Thirty-three migrainous subjects and thirty-two non-headache controls were subjected to 40 min of demanding cognitive tasks and 20 min of recovery during which cranial and peripheral vasomotor responses were registered as well as electrodermal and myographic activity. Subjects of both groups were randomly assigned to two experimental conditions, a so-called 'spontaneous processing condition' and the 'positive coping treatment'. In this treatment condition subjects received a short training in the conscious use of positive self-statements in stress situations. Though a specific pattern of cranial vasomotor responses in migraine subjects could be verified by group statistics, this pattern was only found in very few individuals. Reliable differences between groups could not be identified in other physiological variables either. The hypothesis that the predicted cranial vasomotor specificity in migraine subjects correlates with negative cognitive coping habits in migraine subjects best revealed in the 'spontaneous processing' condition, was not corroborated. The treatment variation regarding coping produced somewhat paradoxical effects, more relaxed and positive self-evaluation (subjective level) and more arousal (physiological level). Results are discussed for their impact on the psycho-biological model of migraine.
