Relaxation therapies in the treatment of psoriasis and possible pathophysiologic mechanisms.

Psychologic factors play a role in many dermatologic disorders, giving rise to the possible use of psychotherapeutic modalities in treatment. Regarding psoriasis, emotional factors have a strong correlation with onset and flare-ups. The psychophysiologic mechanisms involved are not known; however, stress and its effect on the autonomic nervous system and the immune system may play a significant role in the onset and course of psoriasis. Relaxation and mere suggestion also affect the autonomic nervous system and the immune system and therefore may affect the course of the skin disorder. A few case studies have documented successful treatment of psoriasis with hypnosis and biofeedback. Further study of this process is needed, and the role of stress in dermatologic diseases must always be given consideration.
