Twin Dementias: New Clues That Alzheimer’s Often Coexists with FTLD
A Brown University study across 29 NIH-funded centers analyzed 919 autopsy-confirmed patients and found many with Alzheimer’s also have FTLD. Those with both conditions show a broader, more complex mix of neuropsychiatric symptoms (anxiety, delusions, irritability, personality changes, disinhibition) than either disease alone, which could aid earlier recognition and more informed care, even though FTLD lacks disease-modifying treatments.
