Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Blood pressure optimization therapy
Aggressive management of hypertension with appropriate antihypertensive agents to reduce hemodynamic stress on small cerebral vessels and slow disease progression.
Medication management with follow-up
Active treatment with regular monitoring by a healthcare provider is recommended.
Annual ophthalmologic evaluation
Regular eye examinations to detect and monitor retinal vascular changes and ocular anomalies associated with this small vessel disease phenotype.
Additional treatment options
Cardiovascular risk factor modification
Smoking cessation, alcohol limitation, and weight management to reduce overall vascular burden on cerebral small vessels.
lifestyleAntiplatelet therapy for stroke prevention
Low-dose aspirin or other antiplatelet agents may be considered for secondary stroke prevention in patients with evidence of small vessel disease-related ischemic events.
medicationMotor rehabilitation for vascular cognitive impairment
Exercise programs targeting gait, balance, and fine motor control to maintain function and compensate for small vessel disease-related motor deficits.
