| Added Age & Decreased Ability |
Factually, the brain is aging as all the organs that exist in our bodies. the surprising thing is, it turns out the brain can resist the negative effects due to the passage of time, much better than that done by all the other organs of our body.
We naturally know that some elderly people who proved to still have the ability to think are perfect.
In other words, at the age of eighty years we may not be able to exercise as when we were twenty years ago. However it is possible for us to think, invent, and create, at an advanced age. In fact we can do it better than we ever did when I was younger.
However, we can not deny that the passage of time would have an impact on our nerve cells. Therefore, the aging process always go hand in hand with the various changes in psychological temperament, mind, and movement. At the age of eighty years, usually we will find it difficult to determine whether these changes arise due to the growth of biological (natural) of our age-related or due to a disease that can reduce our ability ?!
To determine that the aging brain is indeed happen "naturally", the scientists used two central points of "inaction in general" and "loss of adaptability to the environment". Although the symptoms of dementia in a short time, even immediately, but the onset of brain diseases such as this actually takes place with a very slow and long.
In general, the disease as it starts from some disorders that occur in memory, temperament, and how to talk. But in reality, boundaries between natural aging running and aging that goes along with the disease can not be seen clearly. moreover the two are not mutually prevent each other
