Summary of “Blood-thinning drugs ‘can reduce risk of dementia by up to 48%'”

Blood-thinning drugs could protect against dementia and stroke in people with an irregular heartbeat, research suggests.
A study found that patients being treated for atrial fibrillation were less likely to develop dementia if they were taking anticoagulants.
While the findings could not prove cause and effect, they “Strongly suggested” blood-thinning pills protect against dementia in patients with the condition, the team said.
Atrial fibrillation increases the risk of stroke and blood clots, which some experts think may appear in the brain and help trigger dementia.
Monitoring each person’s progress provided 1.5m years of follow-up during which 26,210 patients were diagnosed with dementia.
“Prof Jeremy Pearson, associate medical director at the British Heart Foundation, said:”Strokes caused by a clot blocking the blood vessels in the brain are a major cause of dementia, and atrial fibrillation is an important risk factor as it increases the chances of these clots forming.
“By treating AF patients with blood-thinning drugs, you reduce the risk of both stroke and dementia.”
“Dr Carol Routledge, head of science at Alzheimer’s Research UK, said:”The findings highlight a need to investigate this link further, but the nature of the study prevents us from firmly concluding that anticoagulants reduce the risk of dementia.
