Alzheimer's Gene Linked to Delirium Risk

Alzheimer's Gene Linked to Delirium Risk

Scientists found that a gene called APOE, which is known to increase the risk of Alzheimer's disease, also directly increases the risk of delirium.

Delirium is a state of confusion that often happens in hospitalized patients.

The study looked at over a million people and found that the APOE gene affects delirium risk even in people who don't have dementia.

This means the gene has a separate role in causing delirium.

The researchers also found proteins that can predict delirium risk years before symptoms appear.

This discovery could help us understand how delirium is linked to future dementia risk.
