Disinhibition: a decrease in the ability to control impulsive behavior. Disinhibited inviduals may speak and act without considering the consquences. They may appear impatient, quick to anger or to laugh. They may race off on a tagnet, interrupt others, speak loudly, and say inappropriate things, and have difficulty inhibiting sexual, agressive, and antisocial behavior. Disinhibition, a noticeable, active behavior, may be said to be the opposite of adynamia; however elements of disinhibition and adynamia frequently occer in the same invidual.
I have talked many times about Bryan's impulse control is little to none. Everytime I go out of town he dumps money out of the bank account. He will go and buy whatever he wants and not even think about the cost. He never thinks that the money he took out of the bank account were for bills or we need our savings for emergencies. Bryan tends to be impatient a lot. If he decides he wants to do something it needs to be right now. He also hoards money and hides it to buy expensive things he wants instead of just asking me to set aside money for whatever he wants. We have found ways to cope with these issues but they aren't fool proof. I think a lot of people with TBI tend to suffer from disinhibition.
