Abstract:
Especially in outpatient settings, dementia is still an underdiagnosed syndrome. The Micro-Mental Test has been developed as a short version of the Mini-Mental-Status Examination (MMSE). We examined the reliability and diagnostic validity of a German version (Mikro-Mental Test). We administered the MMSE and the German version of the Micro-Mental Test to 20 inpatients of a geriatric psychiatry hospital (mean age 74.8+/-8.1 years), 55 patients from a cognitive clinic (mean age 71.9+/-9.1 years), and 27 healthy older adults (mean age 68.5+/-4.1 years). Diagnoses made by an experienced psychiatrist according to ICD-10 criteria served as external criteria. The mean duration for testing with the Micro-Mental Test was 8 min, and with the MMSE 15 min. Test-retest analyses showed satisfactory reliability. With regard to sensitivity and specificity, we found comparable diagnostic validity for the MMSE and the Micro-Mental Test. We suggest that, due to its brevity and diagnostic validity, the Micro-Mental Test is a useful tool for dementia screening in an outpatient setting.
Insights
The German Micro-Mental Test, a brief dementia screening tool, demonstrates reliable and valid diagnostic performance comparable to the Mini-Mental Status Examination (MMSE). This makes it suitable for outpatient settings.
Area of Science:
- Geriatric Psychiatry
- Neurology
- Psychometrics
Background:
- Dementia is frequently underdiagnosed, particularly in outpatient environments.
- The Mini-Mental Status Examination (MMSE) is a common cognitive assessment tool.
- A shorter screening instrument is needed for efficient dementia detection.
Purpose of the Study:
- To evaluate the reliability and diagnostic validity of the German version of the Micro-Mental Test.
- To compare the Micro-Mental Test's performance against the established MMSE.
- To assess the utility of the Micro-Mental Test for dementia screening in outpatient settings.
Main Methods:
- The German Micro-Mental Test and the MMSE were administered to distinct patient groups (geriatric psychiatry inpatients, cognitive clinic patients) and healthy older adults.
- Diagnoses were established by an experienced psychiatrist using ICD-10 criteria as the gold standard.
- Test-retest reliability, sensitivity, and specificity were analyzed for both cognitive tests.
Main Results:
- The German Micro-Mental Test showed satisfactory test-retest reliability.
- Its diagnostic validity, in terms of sensitivity and specificity, was comparable to the MMSE.
- The average administration time for the Micro-Mental Test was 8 minutes, compared to 15 minutes for the MMSE.
Conclusions:
- The German Micro-Mental Test is a reliable and valid tool for dementia screening.
- Its brevity and comparable diagnostic accuracy make it a practical alternative to the MMSE.
- The Micro-Mental Test is recommended for efficient dementia screening in outpatient settings.
