Summary

This completed study looked at over 11,000 adults in Trøndelag, Norway, to find out how many people have dementia and how many are undiagnosed. Researchers used standard tests to measure memory and thinking skills. The goal is to get a clearer picture of dementia rates across Norway and identify who is most likely to miss a diagnosis.

What could go wrong
