At first, Maggie's parents thought she was slacking off. After
the Thanksgiving break, she couldn't concentrate in class, and
after school all she wanted to do was sleep. Her grades began to
drop and she rarely felt like socializing anymore. They were
upset with her, but figured it was just a phase — especially
because her energy finally seemed fine in the spring. But when
the same thing happened the next fall, and Maggie's mood and her
grades plummeted again, they took her to the doctor, who
diagnosed her with a type of depression called seasonal
affective disorder (SAD). About Seasonal Affective Disorder A
form of depression that follows a seasonal pattern, SAD appears
and disappears at the same times each year. People with SAD
usually have symptoms of depression as winter approaches and
daylight hours become shorter. When spring returns and the days
become longer again, they experience relief from the symptoms
and a return to a normal mood and energy level. Signs and
