Diagnosis
Your doctor may determine a diagnosis of depression based on:
- Physical exam. Your doctor may do a physical exam and ask questions about your health. In some cases, depression may be linked to an underlying physical health problem.
- Lab tests. For example, your doctor may do a blood test called a complete blood count or test your thyroid to make sure it’s functioning properly.
- Psychiatric evaluation. Your mental health professional asks about your symptoms, thoughts, feelings and behavior patterns. You may be asked to fill out a questionnaire to help answer these questions.
- DSM-5. Your mental health professional may use the criteria for depression listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association.
FInding the right Medication
If a family member has responded well to an antidepressant, it may be one that could help you. Or you may need to try several medications or a combination of medications before you find one that works. This requires patience, as some medications need several weeks or longer to take full effect and for side effects to ease as your body adjusts.
Inherited traits play a role in how antidepressants affect you. In some cases, where available, results of genetic tests (done by a blood test or cheek swab) may offer clues about how your body may respond to a particular antidepressant. However, other variables besides genetics can affect your response to medication.
Treatment
Medications and psychotherapy are effective for most people with depression. Your primary care doctor or psychiatrist can prescribe medications to relieve symptoms. However, many people with depression also benefit from seeing a psychiatrist, psychologist or other mental health professional.
If you have severe depression, you may need a hospital stay, or you may need to participate in an outpatient treatment program until your symptoms improve.
