Patients who receive anticoagulation with warfarin and anti-platelet
agents such as aspirin appear to be at in increased risk of developing
dementia if they are over-anticoagulated more than 25% of the time,
researchers reported here at the 2014 Annual Meeting of the American
Heart Association (AHA).
“There are multiple hypotheses for how over-anticoagulation can cause
dementia, possibly because over anti-coagulation might cause some
micro-bleeds into the brain,” said Jared Bunch, MD, Intermountain Health
System, Salt Lake City, Utah.
Patients who were chronically over-anticoagulated -- more than 25% of
the time having an International Normalized Ratio (INR) >3 -- had a
5.8% risk of developing dementia during a median of 4 years.
