Stroke results from a blockage in blood vessels inside the brain, which cause a lack of oxygen (ischemia) to the section of the brain cut off from blood and oxygen supply. Lack of oxygen in the brain can cause permanent or irreversible damage. Common side effects are paralysis or loss of use of a particular side of the body, speech impairment, and memory impairment.
Getting oxygen to the areas of the brain will enable re-growth of new blood vessels, and diffuse pressurized oxygen to dormant brain tissues caused by the stroke. HBOT daily treatment can help stimulate the new formation of blood vessels. With new production of neurons, endothelial cells, and macrophages, new blood vessels can reach the de-oxygenated tissues within 60 days of treatment. With the new formed vessels, oxygen can now, more easily, reach the damaged brain tissue. Other therapies, such as physiotherapy are still very important aspects of stroke rehabilitation and patients have been known to make continuous improvement after the initial HBOT treatment with a well structured physical therapy program in combination with maintenance HBOT treatments.
