Decompensation
Pronunciation: dee-kom-pen-SAY-shun
A deterioration in psychiatric functioning in which a person's previously managed symptoms worsen to a degree that disrupts daily living or requires a higher level of care.
Full Definition
In community psychiatry, decompensation refers to the breakdown of an individual's ability to maintain stability despite existing coping mechanisms, medications, or community supports. It is the clinical term for a psychiatric relapse or exacerbation, and may present as resurgence of psychotic symptoms, severe mood disturbance, functional decline, or crisis behavior. Editors encountering this term in clinical documents should note that it is not synonymous with 'relapse' (which implies a return to a prior episode) or with 'crisis' (an acute safety event), though decompensation can precede or precipitate both. The noun is 'decompensation'; the verb is 'to decompensate'; editors should correct the informal 'decomping' in formal documents.
Usage
Usage note: Use 'decompensation' (noun) and 'decompensate' (verb) in formal documents. Avoid the colloquial 'decomping.' Do not use interchangeably with 'crisis' unless the decompensation has escalated to a safety event.
