Impulse control disorder
Impulse control disorders are, as the name implies, characterized by lack of control of a certain impulse in a person. The essence of these disorders is in the fact that a person is committing a certain action or deed, satisfying a certain short term selfish goal or urge, while sacrificing a certain loss.
Impulse control disorders include compulsive gambling, shop lifting, pyromania, as well as CSP (skin picking) and TTM (trichotillomania). These (and other disroders in this category) fall under the scope of OCD (obsessive compulsive disorders).
