A Patient’s Guide to Depression


Depression – a common, serious mood disorder – can undermine quality of life and contribute to disability, especially in more severe or persistent cases.

In a given year, it’s estimated that 1 in 15 adults will experience depression or have at least one major depressive episode. The mood disorder can affect myriad aspects of a person’s life, from one’s ability to tackle daily activities and work to relationships.


While depression is often first diagnosed in adolescents and adults, it can occur at any age. Rather than involving fleeting sadness, hallmarks of the disorder like depressed or low mood and loss of interest or pleasure must continue for at least two weeks for a diagnosis of depression to be made.
