Connections between disrupted body clocks and Alzheimer's disease, and possible treatments

Circadian rhythm disruption (CRD) is increasingly recognized as a central driver of Alzheimer's disease pathology.

• CRD may exacerbate oxidative stress, inflammation, and gut microbiome imbalances, which can impair sleep and metabolic health.
• Oxidative stress, linked to neuronal damage, is both a cause and a consequence of circadian misalignment.
• Mitochondrial dysfunction may further amplify oxidative damage, negatively affecting synaptic function and cognitive stability.
• Gut microbiome dysbiosis is associated with increased neuroinflammation, which could worsen neurodegeneration.
• Time-restricted feeding (TRF) could help restore circadian function and improve aspects of health impacted by CRD, such as oxidative stress and gut microbiome diversity.
