A new study by researchers at the Intermountain Medical Center Heart Institute of more than 10,000 patients treated long term with the blood thinner, Warfarin, reveals higher rates of dementia for patients with atrial fibrillation versus patients without the common heart rhythm disorder.

Can blood thinners cause dementia?

In patients considered at low-risk for stroke, delaying blood-thinning treatment increased the risk for dementia 30 percent. In high-risk patients, a delay increased the risk 136 percent, the researchers reported. The longer the delay in giving blood thinners, the more the risk for dementia, the researchers said.

What are the long term effects of taking warfarin?

Do blood thinners affect your brain?

According to Bunch, it's possible that patients with erratic warfarin levels are more prone to "small clots" or "small bleeds" that could affect the brain. The findings are based on records from over 10,000 patients who were on warfarin for atrial fibrillation or to prevent blood clots from other causes.

Can warfarin affect cognition?

Various reasons are associated with the underuse of warfarin; however, cognitive impairment (CI) has been identified as one of the most common causes for not electing to anticoagulate elderly patients with atrial fibrillation.

Researchers found that among patients with atrial fibrillation being treated with warfarin, the risk of Alzheimer's disease was increased by 2-fold and the rate of vascular dementia 2.5-fold.

What medications can cause memory problems?

Does warfarin increase risk of stroke?

In conclusion, warfarin use among patients with both ESRD and atrial fibrillation associates with an increased risk for stroke. The risk is greatest in warfarin users who do not receive in-facility INR monitoring.

What are the nine drugs that cause Alzheimer's?

Safer Blood-Thinning Drugs to Prevent Stroke

The newer medications are Pradaxa (dabigatran), Xarelto (rivaroxaban), Eliquis (apixaban), and most recently Savaysa (edoxaban) — which work by preventing pooled blood in the heart from clotting. Unlike warfarin, the newer drugs are safer and easier for patients to use.
