Hyperhidrosis: A Case Study and Theoretical Formulation

Abstract

A case study is presented of a 20-year-old male who experienced marked increases in body temperature and profuse sweating of the forehead and trunk when in formal social situations. No other physiological nor psychological manifestations of anxiety were admitted to and no situational avoidance was reported. Pretreatment, posttreatment, and follow-up self-report measures and daily self-monitoring of intensity and frequency of sweating were collected to evaluate treatment effects. Treatment was conducted over a period of 20 weeks. Cued conditioning and desensitisation were initially employed, however treatment effect was difficult to determine. The effects of an inadvertent in vivo exposure in week 6 of treatment and the subsequent change in treatment to exposure and cognitive therapy are discussed. The positive effects of treatment, which led to a decrease in the frequency and intensity of the sweating response, were evident at the completion of treatment and well maintained at 60 weeks follow-up. The use of exposure and cognitive therapy as a suitable treatment for this disorder are discussed in light of other anxiety disorders.
