Disinhibition
Disinhibition can be described as the partial to complete loss of restraint in governing normal social behavior and decision-making processes. It is manifested by impulsivity, poor risk assessment, and the disregard for social conventions. Disinhibited behaviour occurs when one does not follow the social rules about what or where to say or do something. A person with drug-induced disinhibition experiences a decreased ability to concentrate on external social cues guiding appropriate behaviour. They experience a decreased ability to control and manage their immediate impulsive responses to the external environment.
Although for the most part, disinhibition simply allows one to overcome social anxiety in a manner that is quite controllable for the average person. In many cases the disinhibited individual may be unable to disguise some of their emotional responses, sometimes at the expense of politeness, sensitivity, or social appropriateness. Individuals who are disinhibited may come across as rude, loud, tactless or even offensive. For example, a disinhibited person may make a comment about how ugly another person is, giving the impression that they have lost their social manners or are deliberately harassing the person. The disinhibited person may also engage in inappropriate sexual comments and actions.
Disinhibition often occurs along with amnesia and the suppression of anxiety. There are numerous reports of disinhibition occurring along with the administration of benzodiazepines and alcohol.
