An impulse control disorder or ICD is a class of psychiatric disorders characterized by impulsivity – failure to resist a temptation, urge or impulse that may harm oneself or others. Many psychiatric disorders feature impulsivity, including substance-related disorders, paraphilias, antisocial personality disorder, conduct disorder, schizophrenia and mood disorders. The revised fourth edition of the American Psychiatric Association's Diagnostic and statistical manual of mental disorders (DSM-IV-TR) includes the category, "impulse control disorders not elsewhere classified", which consists of kleptomania, pathological gambling, pyromania (fire-starting), trichotillomania (a compulsion to pull one's hair out), intermittent explosive disorder, and "impulse control disorders not otherwise specified". Other disorders such as, dermatillomania (compulsive skin picking), compulsive buying and compulsive non-paraphilic sexual behaviour have been proposed for inclusion in the category.
Five behavioural stages characterize impulsivity: an impulse, growing tension, pleasure from acting, relief from the urge and finally guilt (which may or may not arise).

Famous quotes containing the words impulse, control and/or disorder:
“I think of consciousness as a bottomless lake, whose waters seem transparent, yet into which we can clearly see but a little way. But in this water there are countless objects at different depths; and certain influences will give certain kinds of those objects an upward influence which may be intense enough and continue long enough to bring them into the upper visible layer. After the impulse ceases they commence to sink downwards.”
—Charles Sanders Peirce (1839–1914)
“If someone does something we disapprove of, we regard him as bad if we believe we can deter him from persisting in his conduct, but we regard him as mad if we believe we cannot. In either case, the crucial issue is our control of the other: the more we lose control over him, and the more he assumes control over himself, the more, in case of conflict, we are likely to consider him mad rather than just bad.”
—Thomas Szasz (b. 1920)
“In a town-meeting, the great secret of political science was uncovered, and the problem solved, how to give every individual his fair weight in the government, without any disorder from numbers. In a town-meeting, the roots of society were reached. Here the rich gave counsel, but the poor also; and moreover, the just and the unjust.”
—Ralph Waldo Emerson (1803–1882)
