Ageing reduces the functional capacity of all organs, so does that of the nervous system, the latter is evident in the reduction of cognitive abilities, learning and memory. At the same time the progression of these deficits is very much individual and lifestyle dependent, indicating operation of mechanisms counterbalancing age-dependent decline. In physiological ageing astrocytes undergo morphological atrophy and functional asthenia; astrocytic paralysis facilitates progression of age-dependent neurodegenerative disorders.  Astroglial status and homoeostatic capabilities are influenced by lifestyle including intellectual engagement, social interactions, physical exercise, and healthy diet.  Maintenance of healthy lifestyle is paramount for cognitive longevity.  ER -
