Phenomenology and epidemiology of trichotillomania
Phenomenology and epidemiology of trichotillomania
Trichotillomania is a psychiatric disorder characterized by recurrent hair pulling, leading to hair loss and functional impairment. This chapter reviews the phenomenology and epidemiology of trichotillomania, and considers its relationship with putative obsessive-compulsive spectrum conditions and other body-focused repetitive behaviors. Salient animal models of the disorder, along with findings in human patients using neuroimaging and cognitive probes, are summarized. A brain-based model of trichotillomania is formulated, focusing on affect dysregulation, addiction, and impulse dyscontrol. Finally, the chapter flags cardinal questions for the attention of future clinical and research scrutiny.

Abstract
Trichotillomania is a psychiatric disorder characterized by recurrent hair pulling, leading to hair loss and functional impairment. This chapter reviews the phenomenology and epidemiology of trichotillomania, and considers its relationship with putative obsessive-compulsive spectrum conditions and other body-focused repetitive behaviors. Salient animal models of the disorder, along with findings in human patients using neuroimaging and cognitive probes, are summarized. A brain-based model of trichotillomania is formulated, focusing on affect dysregulation, addiction, and impulse dyscontrol. Finally, the chapter flags cardinal questions for the attention of future clinical and research scrutiny.
