Disinhibition is saying or doing something on a whim, without thinking in advance of what could be the unwanted or even dangerous result. There’s also another way to think of disinhibition: as reduced control over your impulses, or urges, which means being unable to stop, delay, or change (“inhibit”) an action that is not appropriate for the situation you’re in.

Disinhibition is the opposite of inhibition, which means being in control of the way you respond to what’s going on around you.

Do the definitions provided above sound familiar, even if you haven’t heard the word ”disinhibition” before?

If you haveborderline personality disorder(BPD), chances are you’ve seldom, or possibly never, been called “disinhibited.” But you’ve likely heard the word “impulsive” many times. That’s right: Disinhibition andimpulsiveness(also called impulsivity) are essentially the same thing. Disinhibition is common in people with BPD.

Not all states of disinhibition are due to mental health disorders, such as BPD. For example, a traumatic brain injury can lead to disinhibition. Certain medications, such as benzodiazepines, some sleep medications, drugs of abuse and alcohol, can also lead to disinhibition.

What Does Disinhibition Look Like?

Disinhibited or impulsive actions often have unwanted or even harmful outcomes. Why? Because they range from behavior that’s simply inappropriate, such as suddenly grabbing food off someone else’s plate, to unnecessarily risky and even dangerous, such as stealing, setting fires, explosive attacks of rage, orself-injury.

Stages of Disinhibition

You can think of disinhibition as occurring in stages even though only a few seconds may pass between thinking of the impulsive act and doing it:
