Essential facts

Delirium is a state of heightened mental confusion that mainly affects older people. This serious condition typically develops over one to two days and is associated with poor outcomes. People who have delirium have increased risk of needing long-term care and developing more hospital-acquired complications such as falls and pressure ulcers. Delirium is also associated with higher mortality rates. However, it can often be prevented and treated if dealt with urgently.
