Knowra Excoriation disorder Excoriation disorder Excoriation disorder is a mental disorder marked by recurrent skin picking that causes lesions and repeated unsuccessful efforts to stop. It is classified among obsessive-compulsive and related disorders.
Body-focused repetitive behavior : A repetitive action focused on the body, such as skin picking or hair pulling, that can cause tissue damage. Excoriation disorder is classified as a body-focused repetitive behavior.
Diagnostic and Statistical Manual of Mental Disorders : A diagnostic classification manual published by the American Psychiatric Association. Its criteria define the diagnostic features of excoriation disorder.
Differential diagnosis : The process of distinguishing a condition from other disorders with similar signs or symptoms. Assessment rules out skin diseases, substances, and other conditions that could explain the lesions or picking.
Skin lesion : An area of skin with an abnormal change in appearance or structure, caused by disease or injury. Repeated picking can produce lesions, the defining physical consequence of the disorder.
Skin-picking cycle : A recurring pattern in which tension, urges, picking, and short-term relief can reinforce one another. This cycle can help explain why picking continues despite injury and attempts to stop.
Obsessive-compulsive and related disorders : A diagnostic grouping that includes obsessive-compulsive disorder and several related conditions. Excoriation disorder belongs to this category in current diagnostic classifications.
Comorbidity : The presence of two or more disorders in the same person. Depression, anxiety, and obsessive-compulsive disorder can co-occur and affect care.
Scarring : The formation of fibrous tissue as the skin heals after injury. Repeated or deep picking can leave lasting marks.
Habit reversal training : A behavioral treatment that builds awareness of a habit and practices a competing response. It targets picking by helping interrupt the behavior and replace it with another action.
Trichotillomania : A disorder involving recurrent hair pulling that causes hair loss and repeated efforts to reduce or stop pulling. It is a related body-focused repetitive behavior, but targets hair rather than skin.
