Dementia incidence rates fall, but neurodegenerative pathologies show few differences over time

MedPage Today (2/20, George) reports, “Neurodegenerative pathologies have shown few differences over time despite falling dementia incidence rates,” investigators concluded after examining “brain autopsy data” from “over 1,500 deceased people from birth epochs spanning 25 years (1905-1930).” The study also revealed, however, that “brain atherosclerosis and arteriosclerosis were dramatically lower over the years.” The findingswere published online in JAMA Neurology.
