![]() ![]() Use of the Freund clock drawing test within the Mini-Cog as a screening tool for cognitive impairment in elderly patients with or without cancer.Psychometric properties of Clock Drawing Test and MMSE or Short Performance Test (SKT) in dementia screening in a memory clinic population.The Clock Drawing Test for dementia of the Alzheimer's type: A comparison of three scoring methods in a memory disorders clinic.The Mini-Cog versus the Mini-Mental State Examination and the Clock Drawing Test in daily clinical practice: screening value in a German Memory Clinic.CONCLUSION: Although the MMSE showed higher specificities, the weighting between the sensitivities and specificities in all tests prove again the Mini-Cog as a short, valid, and sensitive screening tool. Surprisingly, the depression severity had no effect on the specificity of the Mini-Cog and the CDT, only the MMSE was susceptible for the depression severity. Concerning the depressed patients, the MMSE demonstrated significant higher specificity than the Mini-Cog and the CDT, but also showed the lowest sensitivity for the detection of dementia. Similarly, the specificities of the CDT (83.8%) and MMSE (92.3% at a cut-off ≤24 and 90.8% at ≤25, respectively) against healthy subjects were significantly higher than the specificities against depressed patients (each p < 0.05). RESULTS: The Mini-Cog achieved a specificity of 79.6% against depressed elderly and 100.0% against healthy subjects (p < 0.001). Depression severity was rated by either the Beck Depression Inventory (BDI) or the Geriatric Depression Scale (GDS) depending on the age of the patients. The CDT and an extraction of the three-item recall of the MMSE were used to constitute the Mini-Cog algorithm. METHODS: Data from 142 depressed elderly, 438 dementia patients, and 64 healthy controls were retrospectively analyzed. Furthermore, we analyzed the specificities of all three screening instruments in dependence of actual depression severity. N2 - BACKGROUND: The aim of this study was to assess the specificities of the Mini-Cog, the Clock Drawing Test (CDT), and the Mini-Mental State Examination (MMSE) against depression and healthy controls in a German Memory Clinic. T1 - The Mini-Cog, Clock Drawing Test, and the Mini-Mental State Examination in a German memory clinic: specificity of separation dementia from depression.
