What is Disinhibition?
Disinhibition is literally the opposite of inhibition. and a state where normal social restraints of behaviour are lost. People grow merry with alcohol as the alcohol first anaesthetizes their inhibitions, then their ability to hold a conversation, before finally it removes their ability to stand upright or make their way unassisted.
One of the early signs of hypomania and mania is loss of inhibition. The personality of the person with manic depressive disorder changes, as they at first become the life and soul of the party. As hypomania progresses there is further disinhibition; the individual may engage in extremely frank conversations with colleagues and complete strangers and become over-familiar with people he or she would normally be highly respectful of. The individual will then most likely spend extravagantly, run around starting numerous tasks, act on every impulse, become sexually promiscuous, irritable, and unable to concentrate for more than a couple of minutes as thought process become increasingly disorganized.
