Stroke Prevention in Older Adults: Recent Advances

Area of Science:

• Gerontology
• Neurology
• Cardiovascular Medicine

Background:

• Stroke and dementia risks escalate with age, posing a significant public health challenge.
• Preventing stroke is currently the most effective strategy for preserving cognitive function.
• Age-based therapeutic nihilism in treating older adults is unwarranted and hinders effective care.

Purpose of the Study:

• To review recent advances in stroke prevention relevant to the aging population.
• To highlight strategies that can reduce the incidence of both stroke and dementia.
• To emphasize the importance of age-appropriate and evidence-based interventions for older adults.

Main Methods:

• Review of current literature on stroke prevention strategies.
• Analysis of therapeutic benefits in older versus younger patient populations.
• Discussion of specific interventions including lipid-lowering therapy, blood pressure control, anticoagulation, dietary modifications, B vitamin supplementation, and carotid stenosis management.

Main Results:

• Older patients derive significant benefits from lipid-lowering therapy.
• Stiff arteries necessitate careful blood pressure targets (<120 mmHg systolic).
• Intestinal microbiome, age, and renal function influence dietary recommendations for older adults.
• Direct-acting oral anticoagulants are underutilized in older patients with atrial fibrillation.
• B vitamins effectively lower homocysteine and prevent stroke.
• Endarterectomy is often superior to stenting for carotid stenosis in older patients.

Conclusions:

• Age should not be a barrier to effective stroke prevention therapies.
• Comprehensive strategies including lifestyle modifications and targeted medical interventions can significantly reduce stroke and dementia burden in the elderly.
• Personalized treatment approaches considering factors like arterial stiffness and microbiome are crucial for optimal outcomes in older adults.
