Daily Body Clocks, Metabolic Stress, and Alzheimer's Disease

AI simplified

Abstract

Metabolic stresses may exacerbate Alzheimer's disease through impaired glucose utilization and gut-brain axis dysfunction.

  • Alzheimer's disease involves both genetic and acquired factors, including lifestyle changes and infections.
  • Circadian rhythms regulate brain energy metabolism and influence gut microbiota composition.
  • Gut-derived metabolites can affect the expression of genes related to circadian rhythms and neuroinflammation.
  • Metabolic stresses contribute to systemic inflammation and gut dysbiosis, potentially worsening Alzheimer’s disease.
  • Dietary patterns, such as time-restricted feeding, may support circadian rhythms and reduce neuroinflammation.
