Symptoms and Diagnosis

The first step in diagnosing depression is doing a thorough review of symptoms, any lifestyle factors that could be causing depression, and a complete physical examination. After that, your doctor may want to run one or more of the following tests to confirm the diagnosis or rule out related conditions:

  • Blood Test: To measure thyroid function and glucose levels
  • Complete blood count (CBC): To evaluate your overall health and detect many different disorders associated with the blood.
  • Computed tomography (CT) scan/ Magnetic resonance imaging (MRI): To scan the brain for any problems that may cause depression symptoms
  • Electrocardiogram (EKG): Looks for conditions affecting the heart or blood vessels which may cause depression symptoms.
  • Electroencephalogram (EEG): Measures brain waves to look for problems affecting the brain or nerves that may cause depression symptoms.

There are several psychological tests available to screen for depression and some are geared to a specific age group, like children or the elderly. Your doctor will help you to determine whether this type of test is needed.
