Hello Paula and thanks for using HCM. I have read your query and understand your concerns. MRI results are consistent with small vessels disease of brain. This can result from uncontrolled high blood pressure, Diabetes, high blood fats, and in some cases autoimmune vessels diseases. All these conditions predispose to stroke, so preventive measures include strict control of blood pressure, Diabetes and blood cholesterol control. Using a baby Aspirin once daily helps too in preventing stroke. These measures about preventing stroke are completed by moderate exercises and healthy eating. So, get blood tests about Diabetes and blood lipids first. Hope this helps. Wishing you good health.
