Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Blood pressure management
Antihypertensive medications are essential to control hypertension and reduce risk of hemorrhagic events in small vessel disease.
Drug therapy and clinical monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Neuroimaging surveillance
Regular MRI or CT scans monitor for silent hemorrhages, microbleeds, and disease progression in brain vasculature.
Additional treatment options
Hemorrhage risk modification
Careful review of anticoagulant and antiplatelet medications with neurology consultation to balance stroke prevention against bleeding risk.
medicationSmoking cessation
Complete smoking cessation is critical as tobacco use significantly worsens small vessel disease and increases hemorrhage risk.
lifestyleLow sodium heart-healthy diet
Reduced sodium intake combined with Mediterranean-style diet supports vascular health and blood pressure control.
