Abstract

Groundwork/Aim: The Clock Drawing Test (CDT) is a valid alternative screening tool to the Mini-Mental State Examination (MMSE) and, crucially, it may be completed faster. The aim of our study was to standardize and simplify the CDT scoring system for screening in 3 common atmospheric condition: balmy cognitive damage (MCI), Alzheimer's disease (AD) and mixed dementia (Dr.). Methods: We included 188 subjects (43 healthy volunteers, 49 patients with MCI, 54 patients with Advertisement, and 42 patients with Doc), who performed the MMSE and CDT. The CDT was evaluated using a modified four-point scoring organisation. Results: The salubrious subjects had the highest median values for the MMSE and CDT, followed by patients with MCI, Advertizing and MD. The optimal cut-off for all patients and each patient group separately was 3 out of 4 points. Sensitivity was 89% for Advert, 93% for Md and 83% for all patients, while specificity was 91%. The MMSE produced like results. In comparison to the MMSE, sensitivity for MCI was significantly higher using the CDT (20 vs. 69%, respectively). Conclusion: A simple, 4-point scoring system may be used as a screening method for fast and accurate detection of cognitive impairment in patients with MCI, Advert and MD.
