Depression is an illness characterized by persistent sadness and a loss of interest in activities that you normally enjoy, accompanied by an inability to carry out daily activities, for at least two weeks.

Clinical depression is the more-severe form of depression, also known as major depression or major depressive disorder. It isn't the same as depression caused by a loss, such as the death of a loved one, or a medical condition, such as a thyroid disorder.

Depression is about 50% more common among women than among men. Worldwide, more than 10% of pregnant women and women who have just given birth experience depression (2). More than 700 000 people die due to suicide every year.
