An increased standard of living and environmental factors, such as advances in nutrition, medicine, and public health, are believed to underlie the increase in life expectancy in the developed nations during the 20th century.
However it is discussed if it depends on the slowing of the aging processes.
The nervous system is especially vulnerable to aging, both for the magnitude of the changes and because the impact on its function.
Its vulnerability is manifested in neurodegenerative pathologies, but several changes can be also observed in many individuals during non-pathological aging.
Many individuals experience age-associated cognitive impairment – a decline in cognitive status presenting as deficits in memory and capacities for adequate use of acquired information and mental skills.
Animal studies suggest that both neurodegenerative diseases and age-associated cognitive impairment reflect vulnerability of certain neuronal populations.
Here we discuss some of the neurobiological mech...
