Seasonal affective disorder, or SAD, is a type of
depression that occurs during the same
season each year. You may have SAD if you felt depressed during the last two winters but felt much better in
spring and summer.
Are you worried about depression complications? Even for people who suffer with milder forms of depression, this mood disorder can affect many facets of their life. Clinical depression can complicate serious health conditions such as heart disease or cancer. Depression can lead to problems with pain, sexual desire and performance, and sleep. The more you know about depression complications, the more you'll understand why it's important to not let clinical depression go untreated.
