Seasonal Affective Disorder (SAD) is a common condition in clinical practice, the prevalence is 1 to 10% of the population. SAD is defined as the presence of recurrent major depressive episodes at a particular time of the year with total remission when that season has passed. Different mechanisms are involved in the pathophysiology such as alteration of the circadian rhythm, changes in retinal sensitivity to light, abnormal metabolism of melatonin and decreased secretion of neurotransmitters, especially serotonin. The treatment is based on phototherapy or pharmacotherapy, selection depending on the characteristics of the patient. The aim of this article is to review on this disorder clinic for better recognition and management.
