Atrial fibrillation and cognitive impairment: features of the relationship, developmental and prevention mechanisms

Abstract

The article discusses the development of cognitive deficit in patients with atrial fibrillation (AF) and provides data on mechanisms of the development of cognitive disorders in AF. Under discussion are a possibility of reducing the risk of cognitive disorders with the anticoagulant therapy for prevention of stroke in AF and different properties of different anticoagulants, which may be important for patients. Thus, patients with cognitive disorders are more prone to missing the dose, which may entail serious, possibly fatal consequences. Therefore, the convenience of dosing may be essential. The drug rivaroxaban that has once-a-day dosing schedule and a calendar package, may help the patient better adhere to the doctor’s recommendations. Therefore, rivaroxaban may help improving the compliance, which is the major condition for comprehensive, necessary protection of an elderly patient with AF, including the protection, with high safety, from stroke, from the risk of coronary complications, and from the impairment of kidney function.
