It is normal that some of the functions of the brain of an aging person have the tendency to decline even in the absence of senility or Alzheimer’s illness. It is what the results of a track indicate by researchers of the university of Harvard by 55 adults aged of 60 years to 93 years and 38 others aged of 18 years to 35 years.
None of the 93 participants suffered the illness of Alzheimer or some other trouble susceptible from to affect the cognitive faculties. The American scientists had resort to tools of medical imagery by magnetic resonance to observe the normal modifications that occur in the brain of an aging person in good health.
According to the results, the changes observed in the brain of the aged people in good health are very light when one compares them to those that occur at people affected by Alzheimer’s illness. " Although the brain of a person of 80 years doesn’t function as the one of a young of 20 years, it doesn’t stop the eldests from managing very well when one compares them to the people who endure a real degeneration cerebral clinic", explain the main author of the survey, the Dr Randy Buckner.
The authors of the survey return to have observed, among the aged subjects, a deterioration of synchronism between the previous and posterior regions of the brain, an absent phenomenon at the younger participants. According to the researchers, this decline of the synchronization would explain itself by the normal deterioration of the white matter, a cerebral structure made of nervous fibers assigned to transport information between the different parts of the brain.
