Delirium
Book AppointmentDelirium is a sudden and temporary state of confusion that affects a person’s ability to think clearly, focus, and stay alert. It can develop quickly, often within hours or days, and usually signals an underlying medical problem.
Delirium is common in people who are hospitalised, particularly older adults. It can be triggered by infections such as a urinary tract infection or pneumonia, hospitalisation or surgery, medication side effects, substance use or withdrawal, pain, constipation, dehydration, or changes in surroundings or routine.
Delirium is often reversible when the underlying cause is identified and treated early.
