BRAIN HEALTH

brainhealthThe brain represents only 2% of the human body weight; it receives 15% of the cardiac output, 20% of total body oxygen consumption, and 25% of total body glucose utilization. The energy consumption for the brain to simply survive is 0.1 calories per minute, while this value can be as high as 1.5 calories per minute during crossword puzzle-solving. When neurons in a particular region of the brain are highly active, they consume a great deal of oxygen, which results in recruitment of extra blood flow to that region. Neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, motor neurone disease, and Huntington’s disease are caused by the gradual death of individual neurons, leading to decrements in movement control, memory, and cognition. Mental performance in the human body can be improved by “feeding” the brain with extra oxygen or glucose, according to research published today that could have implications for the treatment of dementia. It’s well known that after about nine minutes of no oxygen, from drowning or whatever, you can kiss your brain good-bye. Brain cells are extremely sensitive to oxygen deprivation and can begin to die within five minutes after oxygen supply has been cut off. Decrease of oxygen supply to the brain even though there is adequate blood flow caused by carbon monoxide poisoning, pollution in our cities, choking or suffocation can create conditions like tiredness, depression, irritability, poor judgment and health problems. Increasing the oxygen supply to the brain and nervous system will reverse these conditions. The oxygen regimen improves alertness, reflexes, memory and apparently intelligence, and may offer the elderly a new weapon against senility and related disorders. Alzheimer’s and Parkinson’s are reported to be responding to it. Alcoholics who start taking oxygen supplement soon loose interest in alcohol.
