Answer Seasonal Affective Disorder, sometimes called SAD, is a mood disorder that occurs with a seasonal pattern. Usually the pattern is of depressed mood that begins in fall or winter and gets better in the springtime. It is usually treated with a combination of psychotherapy, full spectrum light and anti-depressants. Exercise and diet may help, as they do in other mood disorders, but someone who notices severe mood decline during the darker months of the year should seek professional help.
