SymptomsandDiagnosis
Diagnosis
You will be asked about your symptoms and medical history. A physical exam will be done. Information about alcohol use, illegal drugs, prescription medications, supplements, and herbs will also be collected. A psychiatric evaluation will be done.
Bodily fluids may be tested to look for the presence of substances that can cause problems or to look for imbalance in the body. This can be done with:
- Blood tests
- Urine tests
Treatments
Treatment
Treatment will depend on the cause of your psychosis. Talk with your doctor about the best treatment plan for you. Hospitalization may be needed until the psychosis is managed. Options may include one or more of the following:
Psychological Therapy
Psychological therapy treatments are often recommended in addition to medicine. There are several different types of therapies such as:
- Cognitive-behavioral therapy to change unhelpful thinking patterns
- Family therapy to help your family cope with your condition and identify signs that you may need additional help such as wandering or self-harm
- Support groups to talk to others who have had similar experiences
The medical team will help determine which therapy or therapies may be best.
Medications
Medicines may be recommended to control symptoms. The exact type or combination will depend on symptoms and causes. Some options include:
- Antipsychotic medicines—to change the action of certain chemicals in the brain and control abnormal thinking
- Antidepressants
- Antianxiety medicines
- Mood stabilizers
