Seasonal Affective Disorder is unique in a sense when compared to other mood disorders due to the fact that the disorder is only present from late fall to early spring instead of all year round. SAD is considered to be a type of depression that occurs the same time every year. Symptoms of this disorder tend to start off mild and then become more severe as the winter season progresses. These symptoms include: depression, hopelessness, anxiety, loss of energy, social withdraw, and loss of interest in activities you once liked. Treatment for seasonal affective disorder include light therapy, medications and psychotherapy. Light therapy is a unique treatment that mimics sunlight in which we are lacking due to winter. A follow-up post will be done to further discuss light therapy since it is somewhat unfamiliar to many of us.
