Abstract excerpt

Processing speed (PS) is one of the basic elements of cognitive functions and has been regarded as a "common mechanism" which mediates general cognitive decline in aging. The present study of Australian twins (117 monozygotic pairs, 98 dizygotic pairs, and 42 single twins aged 65 years and over), estimated the genetic influences in five measures of PS: Digit Symbol Coding (DS), Trail Making Test A (TMTA), Stroop...
