What determines the >60% prevalence of anxiety/depression comorbidity specifically in Alzheimer's disease?

OPEN

The abstract states anxiety and depression coexist with cognitive impairment in >60% of AD cases but doesn't explain why this comorbidity rate is so high in AD versus other dementias. This mechanistic gap limits targeted intervention development. Gap type: unexplained_observation Source paper: Pharmacogenetics of anxiety and depression in Alzheimer's disease.
