The goal of this observational study is to look at differences in brain blood flow before and after management of risk factors such as high blood pressure and diabetes in patients with lacunar stroke. Participants will be asked to undergo a simple brain blood flow assessment at their initial appointment, whereby they will be asked to sit and stand twice. The patients will then be asked for a follow-up assessment 4 weeks after, identical to the first. This will allow us to look at any changes in brain blood flow from before management of risk factors and 4 weeks after management of risk factors.
