The goal of treatment is to control or reverse the cause of the symptoms. Treatment depends on the condition causing delirium. The person may need to stay in the hospital for a short time.
Stopping or changing medications that worsen confusion, or that are not necessary, may improve mental function. After asking about your medical history, your doctor will discuss medicines and substances that can worsen confusion, such as alcohol.
Disorders that contribute to confusion should be treated. These may include:
- Decreased oxygen (hypoxia)
- Heart failure
- High carbon dioxide levels (hypercapnia)
- Kidney failure
- Liver failure
- Nutritional disorders
- Psychiatric conditions (such as depression)
- Thyroid disorders
Treating medical and mental disorders often greatly improves mental function.
Medicines may be needed to control aggressive or agitated behaviors. These are usually started at very low dosages and adjusted as needed.
Some people with delirium may benefit from hearing aids, glasses, or cataract surgery.
Other treatments that may be helpful:
- Behavior modification to control unacceptable or dangerous behaviors
- Reality orientation to reduce disorientation
