Hypothesis

HBOT at 2.0 ATA for 60 min, 5x/week for 6 weeks enhances hippocampal neurogenesis via BDNF/TrkB signaling to improve memory consolidation

HBOT increases cerebral oxygen tension, creating a favorable microenvironment for NSC proliferation and upregulating BDNF transcription via HIF-1α stabilization, activating TrkB on progenitors.

🧪 Overview

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.

⚖️ Evidence

⚖️ Evidence Matrix3 supports3 contradicts
Supports
BDNF levels correlate with cognitive reserve in AD patients
Supports
HBOT increased BDNF 3-fold in stroke patients
Supports
Reduced AHN contributes to spatial memory deficits in APP mice
Contradicts
Adult hippocampal neurogenesis in aged human AD is controversial and likely too limited
Contradicts
BDNF increase in acute injury models does not translate to chronic amyloid/tau disease
Contradicts
Many AD models show behavioral changes without convincing neurogenesis rescue

IF 12-month-old APP/PS1 mice receive HBOT at 2.0 ATA for 60 min, 5x/week for 6 weeks, THEN hippocampal DCX+ neuroblast density will increase by ≥40% and these mice will exhibit ≥20% better performance on Morris water maze probe trial vs room air controls.
Predicted outcome: DCX+ cell count in dentate gyrus subgranular zone will be ≥40% higher; probe trial platform crossings will be ≥20% greater in HBOT vs control group
Falsification: DCX+ cell density does not differ significantly between HBOT and room air groups (p > 0.05) or Morris water maze probe trial performance is equivalent, indicating no functional neurogenesis improvemen

Predicted outcome: Serum BDNF concentration will be ≥25% higher in HBOT group vs sham, with effect size d ≥ 0.6
Falsification: Serum BDNF in HBOT group differs <25% from sham (p > 0.05) or shows no dose-response with protocol adherence
