Hypothesis

To assess and compare the effectiveness and costs of Phototest, MMSE, and MIS for screening dementia and cognitive impairment.

Conclusion

The Phototest and MIS are more effective and less costly than the MMSE for screening dementia and cognitive impairment.

Supporting Evidence

  • The Phototest showed a diagnostic accuracy of 86% for dementia.
  • The MMSE was found to be the least effective and most expensive option.
  • The effectiveness of the Phototest was similar to that of the MIS.
  • Costs for the MMSE were significantly higher than for the Phototest and MIS.
  • The study included a diverse population with varying educational levels.

Takeaway

This study found that a quick test called Phototest works well for checking if someone has memory problems, and it's cheaper than the usual test.

Methodology

A phase III study was conducted over one year in consecutive patients with suspicion of cognitive impairment or dementia at four primary care centers.

Limitations

The MIS could not be applied to 23 illiterate subjects, which limits its use in certain populations.

Participant Demographics

The mean age of participants was 72.5 years, with 72.1% female and 14.3% illiterate.
