Depression, delirium, and medication context

Mood, acute confusion, medicines, and medicine interactions can change memory and thinking, especially in older adults.

What it is

Depression, delirium, and medicines can affect memory, sleep, and brain function, especially in older adults.[1,2]

Why it matters

NIA lists depression, delirium, medicines, combinations of medicines, alcohol, and other substances as brain-function contexts to review with clinicians.[1]

What it affects

  • Sudden confusion is different from slow memory drift and can follow illness or hospitalization.[1,3]

Interpretation traps

  • Do not stop prescribed medicines on your own; NIA says medication concerns should be discussed with a health care provider.[1]
