Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Medication management with follow-up
Active treatment with regular monitoring by a healthcare provider is recommended.
Regular Brain MRI Surveillance
Periodic neuroimaging with MRI to monitor disease progression, detect new lesions, and assess for complications such as cerebral microbleeds or white matter changes. Imaging schedule is individualized based on clinical presentation and disease severity.
Blood Pressure Management
Strict blood pressure control is essential to reduce stress on small cerebral vessels. Antihypertensive medications are prescribed to maintain optimal blood pressure targets, typically using agents with proven cerebrovascular protective benefits.
Additional treatment options
Cardiovascular Risk Factor Modification
Comprehensive lifestyle modifications including smoking cessation, alcohol limitation, and regular aerobic exercise to reduce overall vascular burden. These changes complement medical therapy and slow disease progression.
lifestyleDASH or Mediterranean Diet
Dietary approaches emphasizing fruits, vegetables, whole grains, and lean proteins while reducing sodium and saturated fats. This eating pattern supports vascular health and helps maintain healthy blood pressure levels.
dietaryNeuropsychological Support
Assessment and management of cognitive changes, emotional adjustments, and psychological impact of living with a progressive cerebrovascular condition. Includes counseling, coping strategies, and family education.
psychologicalWhen to seek medical help
