## In brief

- Hospitalized older adults can suddenly become disoriented and struggle to make sense of their surroundings.
- Delirium disrupts attention, awareness and clear thinking, and its confusion can set in abruptly or come and go.
- The condition can change in severity over time, and the report links such in-hospital confusion to higher dementia risk later in life.

## Why it matters

Delirium during a hospital stay may be an early warning sign of later dementia, so clinicians and families should take sudden confusion in older patients seriously.
