Background: The development of screening instruments will help the primary care team to determine when further comprehensive cognitive assessment is necessary.
Design: A retrospective analysis based on medical records.
Patients and setting: Patients referred to a comprehensive geriatric assessment unit.
Analysis: Cognitive screening and assessment included visual-spatial components: the Mini Mental State Examination, the Clock Drawing Test, the Montreal Cognitive Assessment Test, and the Neurotrax (Mindstreams) computerized cognitive assessment battery.
Results: The average age of the 190 eligible patients was 81.09±5.42 years. Comparing the individual tests with that of the visual-spatial index of Neurotrax, we found the Trail Making B test to be most sensitive (72.4%) and the Cube Test to have the highest specificity (72.8%). A combination of tests resulted in higher sensitivity and lower specificity.
Conclusion: The use of a combination of visual-spatial tests for screening in neurocognitive disorders should be evaluated in further prospective studies.
Keywords: visual-spatial perception, mild cognitive impairment, cognitive assessment, screening tools
