VALUE OF THE SHULMAN-CDT CLOCK DRAWING TEST IN SCREENING COGNITIVE IMPAIRMENT
Main Article Content
Abstract
Background: Cognitive impairment and dementia are increasingly serious health problems in the elderly. Cognitive screening tests are highly valuable in screening and diagnosing dementia, in which the Shulman-CDT scoring system is widely used due to its ease of use and high validity. Objectives: 1. To evaluate the sensitivity, specificity and area under the curve (ROC) of the Shulman-CDT score in 50 patients with complaints of memory loss. 2. To evaluate the correlation between the Shulman-CDT score with MMSE and FAST in assessing cognitive function in patients with complaints of memory loss. Materials and method: Cross-sectional descriptive study on 50 patients with complaints of memory loss examined at the Neurology Clinic, University of Medicine and Pharmacy Hospital at Ho Chi Minh City from January 2023 to June 2023. Results: The Shulman-CDT scale had an average score of 3.42; a sensitivity of 84.1%, a specificity of 83.3% and an area under the curve (ROC) AUC of 0.86 in screening for cognitive impairment. Conclusion: Cognitive impairment is a common disease in the elderly, with a predominance in women and people with low education levels. Assessing cognitive function using the Shulman-CDT scale on people with complaints of memory loss, at the cutoff point of 3/6, 76% of cases had cognitive function decline with a sensitivity of 84.1%. Specificity was 83.3% and area under the curve (ROC)AUC was 0.86. The Shulman-CDT scale has a strong, statistically significant correlation with MMSE and FAST. This scale is influenced by education level, less affected by gender and age.
