- W2912792029 abstract "Background Sleep disturbance, as well as inflammation predict depression risk, which may be due to effects of sleep loss and/or inflammation on affect regulation. We hypothesized that partial sleep deprivation (PSD) would impair emotion recognition in older adults, and that elevated levels of inflammation would be associated with such changes in affect regulation. Methods Older adults (N = 39) aged 61–86 years underwent a night of uninterrupted sleep (US), followed by a night of PSD. After each night, an Emotion Recognition Task was administered in a counterbalanced/crossover-design. Morning levels of Toll-like receptor 4 (TLR-4) stimulated monocyte production of interleukin-6 (IL-6) and tumor necrosis factor were measured three times: at baseline prior to the sleep protocol (BL), after US, and after PSD. Results As compared to US, PSD induced a delay in surprise and fear recognition (p’s Conclusion Sleep loss induces a delay in surprise and fear recognition in older adults. Pre-existing levels of cellular inflammatory responsivity appear to serve as a vulnerability factor for a delay in fear recognition following sleep loss. These findings have implications for persons with an underlying inflammatory disorder, who may be more at risk for having a failure to recognize salient emotions after sleep curtailment.
