Abstract
Objectives
This study longitudinally examined the object naming and semantic fluency of individuals who are at risk for developing Alzheimer's disease (AD) by virtue of having APOEβ4 or a family history of AD.
Methods
A total of 108 participants (40 with a family history of AD and 43 with APOEβ4) completed the Boston Naming Test and the Animal Naming task at initial assessment and after two years.
Results
At baseline, object naming was significantly lower for those with both risk factors, F(2,β99)β=β5.72, pβ<β0.01, but those with either risk factor had significantly lower scores at followβup, F(2,β99)β=β3.41, pβ<β0.05. Semantic fluency (animal naming) was reduced among subjects with the APOEβ4 allele at baseline, F(1,β100)β=β4.02, pβ<β0.05, but it was not associated with either risk factor at followβup.
Conclusions
These deficits may be associated with a prodromal risk for AD and may serve as preβsymptomatic markers for the development of AD. Copyright Β© 2005 John Wiley & Sons, Ltd.
