|a Seasonal affective disorder (SAD), is a mood disorder subtype characterized by recurrent depressive episodes that occur and remit with changes of season. Although recurrent spring-summer depressions have been documented and may be classified as SAD, the most common form of the disorder involves onset of depression in the late fall or early winter with remission in the spring or summer. Thus, winter pattern SAD is the focus of the majority of the light therapy studies presented in this report. The most commonly used and studied form of light therapy involves the use of a light box that administers bright light during a particular time of day, usually in the morning but sometimes in the evening. More recently developed but less studied forms of light therapy include dawn light simulation and the use of light visors
