Hair-Plucking Maniac
Trichotillomania refers to the repetitive and uncontrollable impulse to pull out one's own hair. It was first reported by Hallopeau in 1889. This disease may be a single symptom or may be associated with certain serious mental illnesses, such as mental retardation, depression, anxiety, schizophrenia, obsessive-compulsive neurosis, and drug addiction. The prevalence of trichotillomania in children is 7 times that of adults, and the prevalence in women is 2.5 times that of men. Preschool boys are more likely to suffer from the disease.
