The Human Figure Drawing test as a screen for dementia in the elderly: a community-based study.

Area of Science:

• Neurology
• Gerontology
• Psychometrics

Background:

• The Mini-Mental State Examination (MMSE) is a common dementia screening tool but is limited by its verbal nature.
• The Human Figure Drawing (HFD) test, a non-verbal assessment of visuo-spatial and constructional abilities, was investigated as a potential complement to the MMSE.

Purpose of the Study:

• To evaluate the effectiveness of the HFD test as an adjunct to the MMSE in screening for dementia in an elderly population.
• To compare the diagnostic accuracy of the MMSE alone, the HFD test alone, and their combination.

Main Methods:

• The study involved 461 elderly individuals from the Kungsholmen project.
• Participants underwent both the MMSE and HFD tests.
• Diagnostic accuracy metrics (sensitivity and specificity) were calculated for each test and their combination.

Main Results:

• MMSE scores significantly differed between non-demented individuals and those with varying dementia severity.
• HFD test scores (HFD29 and HFDess) showed similar trends but weaker than MMSE.
• Combining HFD with MMSE increased sensitivity by 4.2%, particularly for mild dementia cases.

Conclusions:

• The HFD test demonstrated limitations in this well-educated population due to a high drop-out rate.
• The modest improvement in detecting mild dementia cases may not outweigh the practical challenges of test administration.
• Further research is needed to assess the HFD test's utility in populations with lower educational attainment.
