The choice of treatment will be determined by several factors, including the type and severity of depression, by previous treatment history, as well as by patient preference. A combination of medications and psychotherapy is used to treat most patients, although mild forms of depression may be treated with psychotherapy alone. Effective treatment is based on an accurate assessment, which identifies the causes of depression in any person. Usually depression is a result of biological, psychological and social factors, and an effective treatment plan is one that identifies all of these and develops strategies to reduce their frequency and intensity. SAD is a type of depression that can occur as winter approaches and the amount of natural light decreases.
Some people feel more tired and depressed during the winter months.
People who experience SAD may gain weight because they crave carbohydrates or sugary foods and sleep excessively. They also may become socially withdrawn or irritable, and are unable to concentrate. An estimated 10 million Americans complain of SAD, and women tend to be more susceptible to it than men. The onset of SAD correlates with decreased day length and is more common in Northern latitudes. As the amount of available daylight declines during the winder, the clock may not be reset correctly, and body rhythms are thrown out of synch.
