Maciejewski, Matthew L.
Background: Centrally active (CA) angiotensin-converting enzyme inhibitors (ACEIs) are able to cross the blood–brain barrier. Small observational studies and mouse models suggest that use of CA versus non-CA ACEIs is associated with a reduced incidence of Alzheimer’s disease and related dementias (ADRD).; Objective: The aim of this research was to assess the effect of CA […]
