Lithium acts to modulate abnormalities at behavioral, cellular, and molecular levels in sleep deprivation‐induced mania‐like behavior
Abstract
Ample amount of data suggests role of rapid eye movement (REM) sleep deprivation as the cause and effect of mania. Studies have also suggested disrupted circadian rhythms contributing to the pathophysiology of mood disorders, including bipolar disorder. However, studies pertaining to circadian genes and effect of lithium treatment on clock genes are scant. Thus, we wanted to determine the effects of REM sleep deprivation on expression of core clock genes and determine whether epigenetics is involved. Next, we wanted to explore ultrastructural abnormalities in the hippocampus. Moreover, we were interested to determine oxidative stress, tumor necrosis factor‐α (TNF‐α), and brain‐derived neurotrophic factor levels in the central and peripheral systems.
