Depression is linked to REM sleep through specific polysomnographic markers, notably a decrease in REM latency {fact:1, fact:2, fact:3} and an increase in total REM sleep [1]. Additionally, neuroimaging studies have identified distinct patterns of cortical activation during the transition to REM sleep in patients diagnosed with depression [2].

referenceNofzinger et al. (2004a) found increased activation of the anterior paralimbic and executive cortex when transitioning from waking to REM sleep in patients with depression.
claimDepressed individuals exhibit specific polysomnographic abnormalities, including shorter rapid eye movement (REM) latency, which is the time elapsed from the onset of sleep to the onset of REM sleep.
claimDepressed individuals exhibit shorter rapid eye movement (REM) latency, defined as a shorter period between sleep onset and REM sleep onset, which persists even after depression treatment.

claimIndividuals with depression exhibit an increase in total REM sleep and a decrease in REM latency, defined as the time between sleep onset and the start of the first REM period.
