Abstract
AD is a multifactorial disorder with a chronic pro-thrombotic component. This study combined physiological and molecular techniques to demonstrate that long-term anticoagulation with dabigatran ameliorated AD pathogenesis in an AD transgenic mouse model. Dabigatran treatment impeded fibrin deposition and was able to prevent cognitive decline, maintain optimal cerebral perfusion, curb neuroinflammation, decrease amyloid pathology, and maintain the integrity of the BBB in the AD mouse brain. The use of dabigatran might be a future candidate treatment to normalize the sustained pro-coagulant state present in AD patients. Further studies are needed to warrant its use in the clinic.
