The heritability of cognitive functioning in very old adults: evidence from Danish twins aged 75 years and older.

Psychology and aging - 1 Jun 2001

McGue M, Christensen K

Abstract excerpt

Heritable influences on cognitive functioning were investigated in a sample of 403 pairs of like-sex Danish twins aged 75 years and older. Twins completed the Mini-Mental State Examination and 3 other cognitive tests. Genetic factors accounted for 26-54% of the variance on these measures, with the balance being due to environmental factors that create differences rather than similarities among reared-together...
