Trichotillomania might be an unusual word, but it is a common obsession: hair pulling. By looking at several ongoing case studies, this program offers fascinating glimpses into obsessive-compulsive disorder, showing firsthand the debilitating physical and emotional effects, as well as outlining a number of treatment options. Brain scans of OCD patients illustrate differences in neural activity. Among the cases presented are Bob and Shirley, who hoard, Liz, who pulls her hair, and Stephanie, whose extreme fear of contamination is linked with her mothering duties. The program also features Dr. Randy Frost of Smith College, a leading expert on hoarding, and Professor Mario Capecchi of the University of Utah, who has altered a single gene in mice to produce trichotillomania.
