disinhibition
Pronunciation: dis-in-hi-BISH-un
Loss of normal behavioral restraints leading to socially inappropriate actions, commonly seen in mania and certain brain disorders.
Full Definition
Disinhibition refers to the loss or reduction of normal psychological and social restraints that typically govern behavior, resulting in impulsive, inappropriate, or socially unacceptable actions. This symptom can manifest as hypersexuality, excessive spending, inappropriate social comments, or disregard for social norms. Disinhibition is commonly observed in manic episodes of bipolar disorder, frontotemporal dementia, traumatic brain injury, and substance intoxication. It differs from impulsivity in that it specifically involves the breakdown of learned social and behavioral controls. Assessment of disinhibition is important for safety planning and treatment decisions in psychiatric care.
Usage
Usage note: Distinguish from general impulsivity or poor judgment.
