Abstract

Sleep-deprived mice exhibited increased stress and signs of accelerated Alzheimer's pathology.

  • Chronic sleep disruption is associated with altered sleep-related behaviors in mice.
  • Increased stress levels were observed in sleep-deprived mice.
  • Mice showed sex-dependent neurodegeneration and protein accumulation following sleep loss.
  • Changes in cellular processes related to waste removal and neuroinflammation were noted.
  • Cognitive impairment correlated with the effects of chronic sleep disruption.
