Depressive mood and circadian rhythms disturbances as outcomes of seasonal affective disorder treatment: A systematic review

Seasonal affective disorder (SAD) is a recurrent illness affecting around 5% of the population at temperate latitudes (Rosenthal et  al., 1984; Lewy et al., 2009). Most frequently, patients experience depressive symptoms during fall and winter, with full remission to normal mood or switch into hypo/mania during spring and summer (Lam et al., 1995; Zauderer and Ganzer, 2015). This predominant manifestation of SAD is called win ter depression (Magnusson and Boivin, 2003).
