We often associate an aging brain to an aging mind, with the underlying idea that aging of the brain will inevitably lead to a significant decline in memory function and/or general cognitive processes. This negative view of aging came from scientific studies performed in the 1970’s. However, in the 1980’s, another theoretical view emerged, which showed that the death of the mind is not an inevitable consequence of human aging. The goal of these studies is to describe the biological and psychological determinants of aging, and to demonstrate that memory never dies. Such a scientific concept has a clear social implication, since it suggests that social support given to our elders could allow them to keep their memory healthy for a very long period of time.
