Screening instruments aid primary care in identifying patients needing cognitive assessment. The Trail Making B test showed high sensitivity, while the Cube Test demonstrated high specificity for neurocognitive disorders.
Area of Science:
- Geriatric Medicine
- Neuropsychology
- Cognitive Assessment
Background:
- Screening instruments are crucial for primary care teams to identify individuals requiring comprehensive cognitive evaluation.
- Early detection of cognitive impairment is essential for timely intervention and management.
Purpose of the Study:
- To evaluate the effectiveness of various visual-spatial tests in screening for neurocognitive disorders.
- To compare the sensitivity and specificity of individual tests and combinations against a computerized cognitive assessment battery.
Main Methods:
- Retrospective analysis of medical records from patients referred to a comprehensive geriatric assessment unit.
- Cognitive screening included Mini Mental State Examination, Clock Drawing Test, Montreal Cognitive Assessment Test, and Neurotrax computerized battery.
- Analysis focused on visual-spatial components of cognitive assessment.
Main Results:
- The study included 190 patients with an average age of 81.09 years.
- Trail Making B test demonstrated the highest sensitivity (72.4%), while the Cube Test showed the highest specificity (72.8%) compared to the Neurotrax visual-spatial index.
- Combining tests improved sensitivity but reduced specificity.
Conclusions:
- The Trail Making B test and Cube Test show promise as screening tools for neurocognitive disorders.
- Further prospective studies are recommended to validate the use of combined visual-spatial tests for screening.
