Hyperbaric oxygen therapy (HBOT) has been studied as a therapy to support stroke recovery.

Here are several ways in which HBOT may benefit individuals recovering from a stroke:

1. Neuroprotection: HBOT can provide neuroprotection by delivering high levels of oxygen to the brain tissue affected by the stroke. This increased oxygenation can help reduce ischemic injury, minimize the extent of brain damage, and preserve neuronal function in the affected area.

2. Reducing Brain Edema: Following a stroke, brain edema (swelling) often occurs, contributing to increased intracranial pressure and further neurological deficits. HBOT has been shown to reduce brain edema by improving tissue oxygenation, enhancing blood flow, and reducing inflammation, thereby alleviating pressure on surrounding brain structures.

3. Promoting Angiogenesis: HBOT stimulates the formation of new blood vessels (angiogenesis) in the ischemic penumbra, the area surrounding the core of the stroke where tissue is at risk of further damage. By enhancing blood flow and oxygen delivery to these regions, HBOT may facilitate tissue repair and recovery.

4. Enhancing Neuroplasticity: Neuroplasticity refers to the brain's ability to reorganize and form new neural connections in response to injury or learning. HBOT may enhance neuroplasticity by providing the necessary oxygen and metabolic support for neuronal repair and regeneration, facilitating functional recovery in stroke survivors.

5. Improving Functional Outcomes: Studies have shown that HBOT can improve functional outcomes in stroke survivors, including motor function, speech and language abilities, cognitive function, and activities of daily living. By promoting neuronal repair and reducing neurological deficits, HBOT may help individuals regain lost function and improve their quality of life post-stroke.

6. Reducing Secondary Brain Injury: In addition to the initial ischemic insult, stroke can lead to secondary brain injury due to factors such as oxidative stress, inflammation, and excitotoxicity. HBOT has antioxidant, anti-inflammatory, and neuroprotective properties that can help mitigate secondary brain injury and promote recovery in stroke survivors.
