pseudodementia
A condition where cognitive impairment mimics dementia but is actually caused by psychiatric disorders, most commonly depression in elderly patients.
Full Definition
Pseudodementia, also known as depression-related cognitive dysfunction, refers to cognitive impairment that resembles dementia but is caused by reversible psychiatric conditions rather than neurodegenerative disease. Most commonly seen in elderly patients with severe depression, this condition can present with memory problems, concentration difficulties, and executive dysfunction that may be indistinguishable from early dementia on initial assessment. Unlike true dementia, pseudodementia typically has a more rapid onset, patients may be aware of their deficits, and cognitive function often improves with treatment of the underlying psychiatric condition. Careful assessment is crucial as depression and dementia can also coexist.
Usage
Usage note: Use with caution as the term is somewhat controversial; prefer 'depression-related cognitive dysfunction'.
