Apply the DSM4 Criteria for Major Depressive Disorder


Major depressive disorder, commonly referred to as depression, affects approximately 25 million people each year in the United States, according to the National Alliance on Mental Illness (NAMI). For reasons not fully understood, depression occurs about 70 percent more frequently in women then men.

It’s important to understand the signs and symptoms of depression so that help and treatment can take place. Otherwise the severity of symptoms and frequency of depressive episodes can increase and become worse.
