Study: Warfarin could increase risk of dementia

Did You Know?

Atrial fibrillation is an arrhythmia and in the U.S., it affects about 3 million adults. Additionally, more than 20 million Americans are on the drug Warfarin. This combination has been studied in order to find a link between patients that have been prescribed Warfarin and have been diagnosed with Atrial fibrillation that were later diagnosed with Dementia.

Furthermore, the study shows that Warfarin might also contribute to dementia (whether the patient had AF or not) if the doses are not optimal, a discovery that is both alarming and frightening considering the 20 million patients that have been prescribed the drug.

The Study

Dr. Jared Bunch, a cardiologist at Intermountain Medical Center, in Murray, Utah is the lead researcher and has explained that there are two concerns. The study found that those that had been diagnosed with atrial fibrillation face an increased risk of dementia without even taking Warfarin, but taking the drug at it’s improper dosage might contribute to dementia.

The Findings

“There is reason to believe that both [atrial fibrillation and Warfarin] could contribute to dementia, in part because of effects on blood flow to the brain.” said Bunch. The findings in the study were culminated through research of over 10,000 patients who were on warfarin for either atrial fibrillation or to prevent blood clots independent of AF.

While there is reason to believe a link exists, the chilling aspect is that researchers discovered that patients that had been taking Warfarin had a known increased risk of dementia if their blood levels of the drug were often much higher or much lower than acceptable therapeutic range.

While the study’s aim was to uncover if the link between the two aforementioned components caused dementia, it seems that the drug itself, with no help from atrial fibrillation, could in fact cause dementia. Bunch continued, “If people’s levels of warfarin were erratic, their dementia risk was higher, whether they had AF or not.”
