SEASONAL AFFECTIVE DISORDER

Seasonal affective disorder, also known as SAD, is the term for the occurrence of depressive episodes at certain times of the year. In this case, depression usually occurs in the fall or winter and gets better in the spring. It must be a pattern for at least two years before a diagnosis is made.

In a depressive episode without a seasonal pattern, symptoms such as lack of sleep and weight loss are common. Depressive episodes that occur in a seasonal pattern differ from typical depressive episodes.

Symptoms include:

sleeping too much
craving carbohydrates
overeating and
weight gain

It is hard to know how many people with depression have a seasonal pattern. Younger people are more likely to be affected than older people. Women may be more likely to have a seasonal pattern than men. The further north you live, the more likely you are to be affected.

Treatment for depressive episodes with a seasonal pattern is the same as for other forms of depression. An antidepressant drug may be used. Bright light therapy may be helpful.

If you feel like your mood disorder is related to changes in the seasons, tell your healthcare provider and ask to be referred to an experienced psychiatrist. This can help you get the best treatment.
