Is Memory Impaired in Seasonal Affective Disorder? A Review of Literature
季节性情感障碍存在记忆损伤吗?

Seasonal Affective Disorder (SAD) has symptoms similar to those of mild to moderate clinical depression, and is common in places where there is seasonally less natural light. A probable cause of the disorder is deficient regulation of melatonin secretion. In contrast to what is the case in non-seasonal depression, memory impairments in SAD are insufficiently studied. Similar impairments to those shown in non-seasonal depression have been shown, but studies are generally to small for reaching statistical significance, and tests employed lack resolution to describe impairments in sufficient detail. A review of available literature is herein reported.
