摘要

The cognitive impairments associated with aging and age-related diseases are a major socio-economic concern for the world's rapidly growing older population. As we get older, subtle changes in nervous system biology manifest as altered sleeping patterns, impaired sensory-motor coordination, mood changes, and impairments in learning and memory. Although, in most people, these deteriorations do not reach the level of incapacitating impairments, they impact the life of a large proportion of aging people. Aging-related changes in neural function can occur at dramatically different rates across individuals and populations, and there is evidence for the involvement of both genetic and environmental risk factors. However, the neurobiological mechanisms affected at the network, cellular and molecular levels are only slowly becoming clearer.
