Symptoms of depression vary from person to person. Thus there’s no specific test to diagnose the condition. Diagnosis of depression is performed through a series of physical exams, lab tests, psychiatric evaluation. Your doctor might also follow the criteria listed under the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to diagnose what type of depression a person is going through.
Treatment of depression consists of a combination of medications, lifestyle therapies, psychotherapy, light therapy, and alternative therapies like herbal supplements and acupuncture. Some doctors also recommend depression help centres for rehab.
