Psychophysiological response patterns in vascular and muscle-contraction headaches

Abstract

The psychophysiological response patterns of 43 headache subjects were compared to the response patterns of 11 nonheadache control subjects. The headache group was composed of subjects diagnosed as suffering from either muscle-contraction (N = 11), classic migraine (N = 11), common migraine (N = 11), or mixed (N = 10) headache. Discriminant analyses indicated that (1) the headache groups could be perfectly differentiated from the nonheadache control group after a period of relaxation and during a period of psychological stress and (2) the stress condition differentiated among the various headache groups. In general, the headache groups showed a higher level of arousal and were more responsive to stress. Also, the response pattern profiles differed among the headache groups in the stress condition. Muscle-contraction subjects tended to respond with higher frontal EMG, and classic migraine and mixed headache groups tended to respond with larger cardiovascular responses.
