Stroke is a disruption of blood to areas of the brain due to a thrombus (blood clot) or blood vessel rupture (aneurysm) in the brain. This can permanently damage these areas but some of the tissues may be recoverable and overall perfusion is enhanced with HBO₂.

Case 1: Mrs. Jaw Feng Ming, age 75, suffered a stroke on February 11th, 2000. She received 40 HBO₂ treatments in June and July 2000 and an additional 10 in November 2000.  She was hospitalized at the Vancouver General Hospital where she received 2 surgeries. Nevertheless, she lost vision and hearing on her left side. On June 14th 2000, she obtained permission from her neurologist to leave hospital and receive HBO₂ at the Richmond Hyperbaric Center. Her daughter describes her mother's condition in a testimonial. 

Case 2: Glenn, age 48, who has CP suffered a stroke in July 2000. He received 10 HBO₂ treatments in March 2001.  He was told by his doctors that he would never move again and should be put in a nursing home. He received 10 HBO₂ treatments at the Richmond Hyperbaric Center and has seen an improvement in his arm movement, which he can now move away from his body. His physiotherapist recently indicated based on his improvements that he will return to 70% of normal. Glenn's wife Susan has noticed that he moves his feet better and stands better as well. Glenn remarked that he concentrates better and attempts more difficult tasks, before treatments he would just give up on them. His ability to make an effort  and retrain himself has improved.
