Abstract
BackgroundThe development of screening instruments will help the primary care team to determine when further comprehensive cognitive assessment is necessary.DesignA retrospective analysis based on medical records.Patients and settingPatients referred to a comprehensive geriatric assessment unit.AnalysisCognitive 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.ResultsThe 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.ConclusionThe use of a combination of visual-spatial tests for screening in neurocognitive disorders should be evaluated in further prospective studies.
