Stroke
Stroke: A stroke or cerebrovascular accident (CVA) occurs when the blood supply to a part of the brain is suddenly interrupted by occlusion (an ischemic stroke) or by hemorrhage (a hemorrhagic stroke). The former, ischemia, is a reduction of blood flow due to occlusion (an obstruction). The latter, hemorrhagic stroke (or intracranial hemorrhage), occurs when a blood vessel in the brain bursts, spilling blood into the spaces surrounding the brain cells or when a cerebral aneurysm ruptures. A stroke is a medical emergency. It generally presents with loss of function of the area of the body controlled by the affected part of the brain, e.g. hemiplegia, loss of speech or vision, impaired swallowing reflex or altered sensation. The immediate and long-term results lead to marked morbitity and mortality. VideosArticles
Hyperbarics As An Alternative Therapy:
Hyperbaric Oxygen Therapy has proven its effectiveness in this condition, world-wide, both in terms of clinical research and with clinical results. 10 years ago, HBOT demonstrated its value in stroke therapy, helping many stroke victims recover far beyond expectation. At this time, it was thought that the primary mechanism of action was HBOT’s influence on recoverable brain tissue (or the ‘penumbra area’ of the brain); in essence, WAKING UP the brain. It was also known that HBOT increases the formation of blood vessels to damaged tissue, so it was thought that a series of HBOT could repair the damage caused by a stroke by both helping ‘wake up’ damaged brain cells and ‘creating new permanent circulation’ to these damaged areas. No matter what causes a stroke, the result is a localized area of damage in the brain called an infarct. The injured area has a central core of damaged tissue that cannot be repaired, surrounded by an area that is not as heavily damaged. Between the damaged tissue and the unaffected, normal brain tissue is a zone called the penumbra. The penumbra contains dormant/idling neurons that are intact but nonfunctioning. HBOT, by providing extra oxygen under pressure, helps wake up these idling cells so they can recover their function. Once these neurons begin working again, many of the symptoms of stroke disappear. |
