One night of total sleep deprivation shown to have antidepressant effect for some people
Major depression has previously been associated with abnormalities in REM sleep. Excess REM sleep would diminish noradrenaline, resulting in decreased binding to the ɑ-2 receptor in the medial frontal lobes comprised of the ACC and the medial prefrontal cortex. The absence of REM sleep with TSD may give some participants a break to improve top-down control of the amygdala, resulting in an antidepressant effect.
