claimDepressed patients exhibit hypermetabolism in the brain's emotional pathways, including the amygdala, anterior cingulate cortex, and related structures, during both waking and NREM sleep.
measurementWhen transitioning from waking to non-REM (NREM) sleep, depressed subjects show smaller decreases in relative metabolism in regions of the frontal, parietal, and temporal cortex compared to healthy individuals, according to Nofzinger et al. (2005) using positron emission tomography.
referenceNofzinger et al. (2005) documented alterations in regional cerebral glucose metabolism across waking and non-rapid eye movement sleep in patients with depression.
