この英文を和訳してほしいです。
Senescence, according to the dictionary, simply means the process or condition of "growing old". However, to biologists and psychologists it connotes "those manifestations in structure and function of a declining or deteriorating nature which take place during the period of life when the mortality rate of a population is accelerated". It also implies progressive and irreversible deterioration. Thus, the connotations are entirely negative. It ignores all the recovery, restoration, growth, development, and improvement of abilities that are possible as humans age.
The assumption that senescence or deterioration is all there is to human aging is a negative from of ageism. On the other hand, to deny the senescence or declines in function that usually accompany aging is a positive from of ageism.
Senility is defined as "the physical and mental infirmity of old age. It is not actually a medical or scientific term, but it is often used by doctors and laypeople alike to "explain" the behavior and condition of older people. Many of the reactive emotional responses of older people, such as depression, grief, and anxiety, are labeled senility and mistakenly considered to be irreversible and untreatable. This is another form of ageism.
Actual brain damage from cerebral arteriosclerosis or Alzheimer's disease probably accounts for only about half of the mental disorders in old age. Only 5 to 10 percent of those over 65 have mental disorders severe enough to interfere with normal function.
