Sudden confusion is an emergency, not ageing
What it is
New confusion over hours or days usually means infection, dehydration or a medication — and it is reversible.
Start preparing
- The tell is speed: dementia changes over months, delirium over hours or days.
- The usual causes are a urine or chest infection, dehydration, constipation, pain, or a new medicine.
- In hospital, familiar faces, glasses, hearing aids, daylight and sleep at night all reduce it.
When to check with a professional
New confusion, seeing things that are not there, or a sudden change in alertness in an older adult should be assessed the same day.
