How is acute delirium diagnosed?
Healthcare providers will ask when symptoms started. They will need to know about any recent accident, head injury, or surgery. Tell them about all current and recent medicines, and any drug or alcohol use. Also tell them about chemical exposure at work or home.
How is acute delirium treated?
If a medical condition is causing your delirium, your healthcare provider will treat the condition first. He or she may make changes to your current medicines. You may also need any of the following:
- Extra liquid may be given if you are dehydrated. The liquid may contain sodium or other chemicals if you have an electrolyte imbalance. You may be given liquid nutrition if needed.
- Antipsychotics help you stop seeing or hearing things that are not real.
- Benzodiazepines are used if your delirium occurs after you suddenly stop using drugs or drinking alcohol.
How can I manage or prevent acute delirium?
- Talk to counselors. Healthcare providers will work with you to help you feel calm and talk about your thoughts and feelings. They will help you remember where you are. They will work to keep you and those around you safe.
- Talk to family and friends. Talk to those around you when you feel lonely or sad. Ask for help when you forget the time, place, or names of people around you.
- Change your surroundings. Keep your home or room quiet and comfortable. Surround yourself with familiar objects. Keep a calendar and clock nearby to remind you of the date and time. Keep pictures of your family and friends nearby. This will help you stay aware of yourself and the area around you. It may also help you feel safe and calm.
- Take all of your medicines as directed. This will help prevent delirium caused by medicines.
- Write daily schedules and routines. Record medical appointments, times to take your medicines, meal times, or any other things to remember. Write down reminders to use the bathroom if you have trouble remembering.
- Eat healthy foods. Healthy foods will help prevent nutrition problems. Examples are fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Ask if you need to be on a special diet. Your healthcare provider may also recommend vitamins or other supplements if needed. Do not take anything without talking to your provider first.
- Drink liquids as directed. Liquids will help prevent dehydration and constipation.
- Exercise as directed. Exercise such as walking can help improve your mood and ability to think clearly. Exercise can also help you sleep more easily. Your healthcare provider can help you create a safe exercise plan.
