Personality changes don't precede clinical onset of Alzheimer's, FSU study shows

A comprehensive study from Florida State University found no evidence that personality changes occur before the onset of mild cognitive impairment or dementia. Researchers analyzed data from over 2,000 individuals and discovered that personality traits remained stable even in the years leading up to clinical diagnosis.
