Abstract
Background: Dementia is very common, but it should also be noted that with age, the prevalence rises steeply, more than mortality. The necessity to screen increases proportionally as the annual incidence increases with age
Objective: To establish the validity and reliability of simple reaction time in cognitive disorder detection.
Methods: A case control study including 90 elderly (30 with normal cognition ,30 with MCI ,30 with early stage dementia ) at Ain Shams University hospitals. Cognitive assessment was done using the Cambridge Cognition Examination (CAMCOG) and the relationship between delayed reaction time and Cognitive decline.
Results: Using the validated Cambridge Cognition Examination cut offs for (normal cognition above 89, MCI between (78 and 89), early stage dementia below 78. We found that better scoring in reaction time was associated with better CAMCOG performance.
Conclusion: The results suggest that reaction time is robustly associated with level of cognitive
function and that the former association between delaying of reaction time with risk of cognitive impairment and dementia in old age.
