Intermittent explosive disorder (IED) is a mental disorder, characterized by specific episodes of violent and aggressive behavior that may cause harm to others or destruction of property. IED is classified in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, under the heading of "Impulse-Control Disorders Not Elsewhere Classified", similar to kleptomania, pyromania, and pathological gambling. Recently, Harvard scientists have announced that more than 5% of US adolescents between the ages of 13 and 17 have suffered from intermittent explosive disorder.
