Heritability of an age-dependent categorical phenotype: cognitive dysfunction.

Twin research and human genetics : the official journal of the International Society for Twin Studies - 1 Feb 2006

Reynolds Chandra A, Fiske Amy, Fratiglioni Laura, Pedersen Nancy L, Gatz Margaret

Abstract excerpt

We investigated the extent to which cognitive dysfunction is shaped by genetic or environmental influences, and whether these factors differ in women and men. All members of the Swedish Twin Registry aged 65 and older were screened by telephone using the TELE, a brief cognitive assessment instrument (Gatz et al., 2002), and the Blessed Dementia Rating Scale (Blessed et al., 1968) from relatives of those who...
