Alzheimer's Disease: I think more
The most terrible disease XXI century may become senile marauds. Life expectancy in developed countries is constantly growing: the projections demographers, for example, half of girls born in 2000, live to 100 years. At the same time, after 65 years, the man threatened senile dementia - Alzheimer's disease. If scientists did not find drugs against the disease, it has been 50 years in the world will be 45 million marauds - more than cancer patients.
The American scientist Steven Austad believes that the average person will survive until the 150 the anniversary because, in his view, thanks to modern technology will soon be constructed of high quality and biologically adapted to the body «spare parts». According to another American scientist Jay Olshansky, the average length of human life in the XXII century, despite the gene therapy and cloning, will not exceed 130 years.
Studies have long shown that they have achieved so old age thanks to good health, and many continue to keep it until the end of his days
Long, who studied Dr. Thomas Perlz from Harvard Medical School, managed to avoid many of senile diseases - stroke, cardiovascular disease and others. According to Dr. Perzl sharp rise in long-livers in the United States over the past 10 years caused massive changes in lifestyle: Americans have to monitor their weight is healthy food, less smoke and more in sports. It is the combination of good heredity, a good environment and healthy lifestyles, according to scientists, and ensures longevity.
Physiology of aging studies have shown that the aging process involves two closely related system of the body: endocrine (hormone responsible for the formulation) and immunity (protecting the body against infection). From the age of the body resistance to disease drops. Scientists attribute this to age in violation of endocrine balance: a substance produced by the beginning of a larger, others - in smaller numbers. So, even if the medicine man learns to replace all the fastest frayed organs (heart, lungs, liver), it is unlikely to make him immortal.
Another more wear body, which can not yet be replaced - it is the brain. According to Lynn Adler, a pioneer in the study of long-livers in the United States, the most important problem associated with aging - a violation of the functions of the brain and senile dementia caused by the disease, first described in detail by German doctor Alloiz Alzheimer and called his name.
