Genetic and environmental links between cognitive and physical functions in old age.

The journals of gerontology. Series B, Psychological sciences and social sciences - 1 Jan 2009

Abstract excerpt

In old age, cognitive and physical functions are correlated. Knowing the correlations between genetic and environmental influences underlying this correlation can help to clarify the reasons for the observable (phenotypic) correlation. We estimated these correlations in a sample of 1,053 pairs of twins from the Longitudinal Study of Aging Danish Twins. Cognitive function was measured using forward and backward...
