Fact 8: Small Vessel Disease and its Link to Stroke
A stroke, known for its rapid onset and potentially devastating consequences, is another serious condition associated with small vessel disease. Strokes often result from the interruption of blood flow to the brain. If small vessels become damaged or blocked – a common occurrence in SVD – the brain cells can be deprived of oxygen and vital nutrients, causing a stroke.
Small vessel disease is considered a significant cause of ischemic strokes, specifically a subtype referred to as lacunar strokes. These are small infarcts or ‘lacunes’ in the deep structures of the brain, occurring as a result of occlusion in a single small penetrating artery. The risk of lacunar strokes escalates with the progression of small vessel disease, underscoring the seriousness of this condition.
Understanding the link between small vessel disease and stroke is crucial for prevention and treatment. If SVD is detected early, preventative measures can be taken to lower the risk of stroke. Such measures may include medication to control hypertension or high cholesterol levels, lifestyle modifications, or in some cases, surgical intervention.(8)
