The Role of Adult Hippocampal Neurogenesis in Alzheimer's Disease: Mechanisms, Therapeutic Potential, and Future Directions

Alzheimers disease (AD) is characterized by progressive cognitive deterioration. Besides the pathological features of amyloid-beta plaques and tau tangles, emerging research implicates impaired adult hippocampal neurogenesis (AHN) in the dentate gyrus as a contributing factor. Impaired AHN in AD is marked by reduced neural stem cells activation, diminished progenitor cell proliferation, and abnormal neuronal maturation. This review explores the role of AHN in AD, delves into the disrupted molecular mechanisms underlying AHN dysfunction in AD, while assesses potential therapeutic strategies aimed at restoring neurogenesis to treat AD. Understanding AHNs role in AD could inform future diagnostic and therapeutic approaches.
