Abstract

Circadian rhythm disruption is prevalent in contemporary society and is reported from the early stages of Alzheimer's disease (AD).

  • Mammalian cells exhibit circadian rhythms in metabolism and energetics.
  • New pathways of circadian timekeeping include non-transcriptional oscillations, post-translational modifications, epigenetics, and cellular signaling.
  • Circadian rhythm disruption may contribute to neurodegeneration and is linked to various factors such as light-noise, shift work, and transmeridian travel.
  • Bright light therapy combined with chronobiotics may be beneficial for treating cognitive symptoms in advanced AD patients.
  • Potential targets for future management of AD include clock proteins and clock-controlled proteins.
