Symptoms of Depression
Although there is no blood test to diagnose depression, there are well-developed guidelines used by health care professionals to diagnose major depressive disorder. One of these guidelines, developed by the American Psychiatric Association, is called the DSM-IV®. Your health care professional may ask you questions based on this established diagnostic tool.
According to the DSM-IV, major depressive disorder (or "depression") is diagnosed when five or more of the following symptoms of depression are present for most of the day, nearly every day for at least 2 weeks. At least one of the symptoms must be either persistent sad or "empty" feelings or loss of interest in activities.
- Constant sadness
- Irritability
- Hopelessness
- Trouble sleeping
- Low energy or fatigue
- Feeling worthless or guilty for no reason
- Significant weight change
- Difficulty concentrating
- Loss of interest in favorite activities
Be sure to tell your health care professional if you're experiencing any of these symptoms as described by the DSM-IV. Also, tell your health care professional if your symptoms are affecting your ability to function at home, at work, or with family, friends, or colleagues.
Call a health care professional right away if you or your family member has any of the following symptoms, especially if they are new, worse, or worry you:
