Hyperbaric Oxygen Therapy (HBOT) for Parkinson's Disease
Also known as: HBOT, HBO, Hyperbaric medicine
HBOT promotes neuroplasticity and may compensate for dopaminergic neuron loss through enhanced brain oxygenation.
Mechanism of Action
HBOT enhances brain oxygenation, promotes angiogenesis in hypoperfused basal ganglia, mobilizes stem cells for neural repair, and activates BDNF expression. Intermittent hyperoxia protocols may trigger neuroplasticity cascades.
General mechanism: Pressurized oxygen delivery. Hyperoxia/normoxia cycling activates HIF pathway, stem cell mobilization, angiogenesis, anti-inflammatory signaling.
Current Evidence
Small studies show motor and cognitive improvement in PD patients after HBOT protocols. Mechanism consistent with neuroplasticity enhancement. Larger trials needed.
Clinical Status: Small clinical studies positive. Phase II trials planned.
Safety Profile
Generally safe. Ear/sinus barotrauma, oxygen toxicity seizures (rare). Contraindicated with untreated pneumothorax. Specialized facility required.
Key Research Questions
- Does HBOT improve basal ganglia oxygenation and function in PD?
- Can HBOT-induced neuroplasticity compensate for dopaminergic loss?
