Mechanistic description

Alzheimer’s pathology disrupts circadian PER1/2 and BMAL1 rhythms in hippocampal neurons. Gamma entrainment, particularly during evening hours, reactivates CREB phosphorylation at Ser133 to restore Per1/2 transcription and resynchronize hippocampal temporal coding with cortical circadian signals. This integrates a systems-level circadian dimension not addressed by other hypotheses. However, it is the least developed mechanistically and the most temporally constrained (requires evening timing).

Mechanism / pathway

  1. PER1/PER2 (circadian clock genes); ARNTL (BMAL1); CREBBP (CREB-S133P); RORA (RORα)
  2. Alzheimer's disease

Evidence for (3)

    PMID:37243481

Evidence against (2)

  • Mechanistic pathway from gamma entrainment to clock gene restoration is underdeveloped

    PMID:37243481

  • Evening timing requirement adds clinical compliance complexity
