What is Major Depressive Disorder?

Major Depressive Disorder, or MDD, is categorized by depressive episodes that last two weeks or longer.  During this time, sufferers will experience symptoms every day for the majority of the day.  For some, MDD may only occur once, while others will experience multiple episodes throughout their lifetime.

Symptoms of major depressive disorder may include:

• Feelings of uselessness and hopelessness
• Persistent sadness
• Feelings of guilt
• Changes in eating and sleeping patterns
• Loss of interest in activities once enjoyed
