Even more encouraging, the study says prior research may have ignored positive age-related attributes that preserve or even enhance decision-making, like life experience, reasoning ability and accumulated knowledge.
Attributes such as graying hair, while age-related, are attributes and therefore not included.
Finally, and unexpectedly, the age-related physical attributes showed a considerable dependence on our video- activity score.
Our video- activity score showed a high agreement (r = 0.81) with video-based movement ratings, but also considerable associations with age-related physical attributes.
Others have found similar age-related patterns and attributed this slight increase to menopausal hormonal and immunological changes that may facilitate HPV DNA detection or reactivate latent infections from exposures earlier in life (reviewed by Bosch et al (2008)).
Age-related differences may be attributed to cognitive maturation and decline (Baltes et al. 2006).
Additionally age-related disease is often attributed to inflammatory responses.
In vitro preparations of whole isolated muscle remove the influence of neural factors, so that age-related changes can be attributed to changes within the muscle tissue itself.
These findings support prior work attributing age-related cognitive deficits to reduced synapse number (decreased post-synaptic densities) [57], [70], [78], [79] and Ca2+ dyshomeostasis, a key and well-supported hypothesis of neuronal dysfunction with aging [80], [81], [82], [83], [84], [85].
Age-related reduction in adiponectin attributed to hormonal changes and increasing fat mass, occurring in pubertal stage, had been reported (5, 8, 9).
Whether this age-related increase could be attributed to later placement and longer exposure to neglect and abuse was not explored.
