Low levels of vitamin D, B12, and folate increase risk for cognitive dysfunction in patients with AF; however, the value of supplementation remains unproven. Calcium supplementation in women has been associated with increased dementia risk. The value of modulating cognitive function on the basis of educational interventions is uncertain.
Appropriate anticoagulation in patients with AF and stroke risk factors should be applied for the prevention of cognitive dysfunction. Consider a non-vitamin K antagonist oral anticoagulant instead of a vitamin K antagonist when using oral anticoagulation for the prevention of stroke in AF, which may have a beneficial effect on subsequent cognitive disorders. In patients with AF managed with long-term vitamin K antagonists, a high anticoagulation time in therapeutic range may be beneficial for optimal prevention of new-onset dementia.
