Links Between Gut Bacteria Imbalance, Body Clock Disruption, and Early Signs of Alzheimer's Disease

Updated

Abstract

Gut-derived metabolites like calprotectin and trimethylamine-N-oxide may play a key role in the pathogenesis of Alzheimer's disease (AD).

  • Gut dysbiosis is characterized by imbalanced gut microbiota and compromised intestinal integrity, which can lead to the entry of bacterial metabolites into the bloodstream.
  • Circadian disruption is associated with increased accumulation of amyloid-beta and tau proteins, which are linked to AD progression.
  • Circadian dysregulation may contribute to the development of gut dysbiosis.
  • Potential biomarkers related to gut dysbiosis and circadian disruption were identified in preclinical and clinical studies of AD.
  • Understanding the relationship between the microbiota-gut-brain axis and circadian rhythms could assist in the early diagnosis of AD and the creation of targeted therapies.
