Cause Brain Damage: Noise is another much neglected example of the nefarious effects of environmental pollution. Since steady, intense noise inflicts irreversible damage on the nervous system of the ear, American courts recognize its effect as an "occupational dis¬ease" and award compensation to workers whose hearing has been affected by exposure during work. In many cases, however, the level of city noise equals, and may exceed, that considered on the borderline of safety in industrial work. Re¬cent laboratory investigations indicate that supposedly toler¬able noise levels can cause brain damage ear damage in animals, and that sounds not sufficiently loud to awaken sleeping persons never¬theless affect their brain waves.
Among the most interesting developments in brain studies was a finding that corrected the long-held conviction that glucose was the only fuel the brain was capable of using. George Cahill studied brain metabolism in persons who fasted for more than 30 days as part of a weight reduction program. By sampling blood entering and leaving the head, he was able to show that during fasting the brain will readily metabo¬lize fatty acids, the breakdown products from deposits of body fat. Careful intelligence tests before and after the fast failed to show any mental impairment during the period of fasting. Cahill said that in fact the subjects were at least as sharp after fasting, and maybe a bit sharper.See Also And Brain Neoplasms:Cancer of the testicle and ovary, malignant bone tumors, and brain neoplasms show varying degrees of response to treatment with X-rays.
Certain tumors of lymphoid and reticulo-endothelial origin, notably Hodgkin's disease, lymphosarcoma, and reticulum-cell sarcoma can be effectively managed with radiotherapy. When com¬bined with steroids such as cortisone and ACTH, and chemical agents such as nitrogen mustard, treat¬ment can result in prolongation of normal useful life.
1. If new medical techniques can prolong a healthy life far beyond the present span, who will be selected to remain alive? Society, through law, probably will not leave it to the workings of the marketplace or the caprice of physicians. At the very least, it will try to prevent a black market in hearts and lungs. But if science manages to transplant a human brain, the law will be in serious trouble. Which individual will be con¬sidered legally "alive"—the one into whose functioning body the new brain has been deposited, or the one whose brain with all its memories has merely moved to a new home?
On The Other Hand See Brain Damage:Certain types of feeble-mindedness tend to run in families. Low mentality occurs when some factor that ensures normal development is lacking in both parents. Difficulty arises in the diagnosis of true mental deficiency. There is no conclusive evidence that all cases of feeble-minded-ness are clearly hereditary. Some may be congenital, i.e., acquired during prenatal life. At birth severe lack of oxygen may cause brain damage. Other cases may be intensified by an impoverished social environment.
Improved enforcement of the narcotics laws was behind the reorganization plan. Alarm was expressed over the increased use of amphet¬amines, or "speed," among the young. Amphet¬amines, when injected, act quickly on the cen¬tral nervous system, and this might lead to psychosis or brain damage. A report of the California Rehabilitation Center, at Corona, pre¬dicted more crimes of violence due to "the paranoid state and the hypertension associated with amphetamine use." |
