Objective: The aim of this study is to assess whether impaired attention, quantified by Digit Span subtest of Wecshler Memory Scale-Revised (WMS-R), can be alerting for faster cognitive decline in memory and executive functions in incoming years.
Method: We evaluated twenty-eight subjects (9 men and 19 women; mean age 59.7±9.9 with a range of 37-77 years, mean education 10.0±4.1 with a range of 5-15 years) with impaired attention in which digit span scores were one standard deviation below of age and education specific standards but preserved memory and executive functions and sixteen subjects (5 men, 11 women, mean age 57.6±8.1 with a range of 44-69 years, mean education 10.1±4.3 with a range of 5-15 years) with intact cognitive function in all domains. The neuropsychological evaluation included digit span, visual reproduction and associate learning subscales of WMS-R, Verbal Memory Processes Test, Stroop Test and Categorical Fluency Test. Both groups were reassessed after 6.6±1.1 years with the same neuropsychological test battery. Wilcoxon test was used to compare re-evaluation of neuropsychological measures in both groups.
Results: In longitudinal assessment, comparing to control group, impaired attention group showed significantly decreased scores of the highest verbal learning (p=0.001), verbal total learning (p=0.02), Stroop spontaneous correction (p=0.043) and animal list of categorical verbal fluency (p=0.011).
