Background: Sleep deprivation (SD) is emerging as a hot topic due to its health concerns. There are compelling reasons for a tremendous interest in neuroscience of sleep in recent years. Objectives: We aimed to evaluate how total sleep deprivation (TSD) and chronic partial sleep restriction (CPSR) might affect memory, anxiety-related behaviors, and the serum level of neurochemical markers such as brain-derived neurotrophic factor (BDNF) and corticosterone in a rat model. Results: Our results demonstrated that TSD (P < 0.001) and CPSR (P < 0.001) induce memory impairment while exert anxiolytic-like effects in comparison with controls. Data showed that CPSR causes more memory impairment and anxiolytic-like effect in comparison to TSD (P < 0.001).These interventions however, did not alter the locomotor activity. Serum corticosterone level raised dramatically in CPSR rats in comparison to TSD and controls. Although the difference in serum BDNF level between TSD and CPSR arms was insignificant, it was markedly decreased in comparison to corresponding controls (P < 0.001). Conclusions: Our findings suggest the more pronounced effect of CPSR rather than TSD in impairing aversive memory and reducing anxiety. Decreased BDNF and peaked corticosterone level in TSD and CPSR suggest the probable inflammatory processes involved in possible insults to the brain caused by SD.
