Can untreated atrial fibrillation (AFib) raise the risk of cognitive decline?

Atrial fibrillation is a common heart rhythm disorder that may increase the risk of stroke and reduced brain perfusion. In this episode, we examine how untreated AFib may be linked to cognitive decline and how risk is managed in Europe.

In this episode, we cover:

• What atrial fibrillation is (an irregular, often rapid heart rhythm)

• How AFib increases stroke and clot risk

• The connection between silent microemboli and brain injury

• Research linking AFib to dementia and cognitive impairment

• The role of anticoagulation therapy

• Rate control vs rhythm control strategies

• When heart rhythm monitoring is recommended

• When urgent in-person assessment is required

Doctors assess CHA₂DS₂-VASc stroke risk score, bleeding risk, symptom burden, blood pressure, diabetes status, and echocardiogram findings before recommending treatment. Anticoagulation decisions require careful evaluation and are not appropriate without proper risk stratification. New or worsening neurological symptoms require emergency care.

This episode reflects how cardiovascular and cognitive risks are reviewed within structured medical assessment in European telemedicine at Mobi Doctor.
