pseudodementia
Pronunciation: SOO-doh-dih-MEN-sha
Reversible cognitive impairment caused by psychiatric conditions, particularly severe depression.
Full Definition
Pseudodementia refers to cognitive impairment that mimics dementia but is actually caused by reversible psychiatric conditions, most commonly severe depression. Unlike true neurocognitive disorders, pseudodementia typically shows rapid onset, inconsistent cognitive deficits, preserved insight, and improvement with psychiatric treatment. Patients may demonstrate 'don't know' responses to cognitive testing rather than confabulated answers. Distinguishing pseudodementia from early dementia is crucial in neuropsychiatric practice, as appropriate antidepressant treatment can lead to complete cognitive recovery.
Usage
Usage note: Write as one word; emphasize reversible nature when documenting.
