Disinhibition

DISINHIBITION AND IMPULSIVENESS
In Brain Injury:

Following lobotomy or massive or even mild frontal injuries patients may become -emotionally labile -irritable -euphoric -aggressive and quick to anger -yet unable to maintain a grudge or a stable mood state

Depending on the degree of damage, they may become -Unrestrained -Over-talkative -Tactless - saying whatever "pops into their head", with little or no concern as to the effect their behavior has on others or what personal consequences may result

With severe injuries patients may seem inordinantly disinhibited and influenced by the immediacy of a situation: -Buying things they cannot afford -Lending money when they themselves are in need -Acting and speaking "without thinking."

Following severe injuries there may be periods of gross disinhibition which may consist of: <span style="color: #000000; font-family: 'Times New Roman',serif;">-Loud, boisterous, and grandiose speech <span style="color: #000000; font-family: 'Times New Roman',serif;">-Singing <span style="color: #000000; font-family: 'Times New Roman',serif;">-Yelling <span style="color: #000000; font-family: 'Times New Roman',serif;">-Beating on trays or destruction of furniture. <span style="color: #000000; font-family: 'Times New Roman',serif;">-Tearing of clothes <span style="color: #000000; font-family: 'Times New Roman',serif;">-May impulsively strike doctors, nurses, or relatives and thus behave in a thoroughly labile, aggressive, callous and irresponsible manner.

<span style="color: #000000; font-family: 'Times New Roman',serif;">Impulsiveness can also be quite subtle such as one person who, on going to the train station, got into the train which happened to arrive first, although it was going in the opposite direction.
