Comparing 2 hypotheses side-by-side
HBOT increases cerebral oxygen tension, creating a favorable microenvironment for NSC proliferation and upregulating BDNF transcription via HIF-1α stabilization, activating TrkB on progenitors. However, adult hippocampal neurogenesis in aged human AD is controversial, and increased BDNF after acute injury does not imply restored neurogenesis in chronic amyloid/tau disease.
## Mechanistic Overview Hippocampal CA3-CA1 synaptic rescue via DHHC2-mediated PSD95 palmitoylation stabilization starts from the claim that modulating BDNF within the disease context of Alzheimer's disease can redirect a disease-relevant process.
