Not all people with depression will show all symptoms or have them to the same degree. If a person has four or more symptoms, for more than two weeks, consult a medical doctor or psychiatrist. While the symptoms specified for all groups below generally characterize major depression, there are other disorders with similar characteristics including: unipolar depression, bipolar illness, anxiety disorder, or attention deficit disorder with or without hyperactivity. Remember that only a medical doctor can diagnose depression.

In Infants

It’s important to understand what constitutes normal development in infants, children and adolescents vs. what may be signs of a depressive illness.

• Failure to gain weight (not due to other medical illness).

• Unmotivated in play.

• Restless, oversensitive to noise or touch.
