Are there any side effects caused by the ultrasound procedure?

We did not see any serious clinical or other adverse events. We define that as anything serious—anything you could be hospitalized for. In addition to not seeing any bleeding or swelling, patients didn’t have any physical symptoms whatsoever from the procedure. It didn’t impact any of their brain function that we measured. Some minor side effects included discomfort with putting the frame around their head or being in an MRI scanner for about two and a half hours. That can be tiresome for many patients. However, those are temporary and what we call minor adverse events. All of these patients were discharged on the first day after the procedure and have expressed interest in participating in the next phase of the study. That’s an indirect measure of how well-tolerated it was.
