The most common form is known as major depressive disorder.3
Major depressive disorder is characterized by a fairly lengthy period of time (at least two weeks) during which a person feels sad or hopeless or lacks focus in life, on a daily or almost daily basis, for the most part of each day. This condition is associated with many other symptoms which can have repercussions emotionally, socially, professionally and in other significant areas of life.4
Fortunately, if properly managed, recovery is possible for patients suffering from major depressive disorder.1
