Mechanistic description

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.

Mechanism / pathway

  1. BDNF
  2. neurodegeneration

Evidence for (3)

  • BDNF levels correlate with cognitive reserve in AD patients

    PMID:29804827

  • HBOT increased BDNF 3-fold in stroke patients

    PMID:27739524

  • Reduced AHN contributes to spatial memory deficits in APP mice

    PMID:26709150

Evidence against (3)

  • Adult hippocampal neurogenesis in aged human AD is controversial and likely too limited

    PMID:N/A

  • BDNF increase in acute injury models does not translate to chronic amyloid/tau disease

    PMID:N/A

  • Many AD models show behavioral changes without convincing neurogenesis rescue

    PMID:N/A
