medication-induced cognitive impairment
Reversible decline in cognitive function caused by medications, particularly common in older adults.
Full Definition
Medication-induced cognitive impairment refers to a decline in cognitive function that results from the use of certain medications, which is potentially reversible upon medication discontinuation or dose reduction. This condition is particularly common in older adults due to age-related changes in drug metabolism and increased sensitivity to medications. Commonly implicated medications include anticholinergics, benzodiazepines, opioids, anticonvulsants, and some cardiovascular medications. Recognition of this condition is crucial as it may be mistaken for dementia, leading to inappropriate treatment and unnecessary distress.
Usage
Usage note: Important to distinguish from irreversible neurodegenerative conditions.
