Seasonal Affective Disorder and Light Therapy
2008, Sleep Medicine ClinicsCitation Excerpt :Further, light may also reduce the severity of winter symptoms in patients who report combined seasonal and nonseasonal mood disturbances. In most but not all cases of SAD, the atypical depressive symptoms of hyperphagia, weight gain, and hypersomnia will be present, and light therapy has been predicted to be most effective for patients reporting these atypical depressive symptoms [77]. Among the standard elements of clinical assessment, inquiry of possible SAD sufferers should include seasonal patterns over previous years, seasonality and mood symptoms, whether unipolar or bipolar, anticipatory anxiety about the fall and winter, evidence of “skipped” winters or year-round depression, effect of travel to warm sunny locales, cold tolerance, ophthalmologic history, current medications and photosensitizing medications, and family history of affective disorders and of alcoholism.
Efficacy of light therapy in nonseasonal depression: A systematic review
2008, Journal of Affective DisordersChapter 1: The human hypothalamus in metabolic and episodic disorders
2006, Progress in Brain ResearchCitation Excerpt :Patients with SAD report atypical symptoms of increased appetite, particularly “carbohydrate craving,” increased body weight and sleepiness during their winter depression (Kräuchi and Wirz-Justice, 1988). Appetitive symptoms are particularly sensitive to bright-light therapy (Kräuchi et al., 1993). Furthermore, depressed patients have alterations in their hypothalamo–pituitary–thyroid (HPT)-axis (Musselman and Nemeroff, 1996), as both basal thyroid stimulating hormone (TSH) and thyroxin levels were found to be altered in melancholic and major depressed patients (Maes et al., 1993b), which may also affect metabolism.
