Unfortunately, I don’t know anything about the particular devices they are using so I would rely on Northwestern University to inform you as I imagine they have detailed information they can share with you.

In preliminary research I see on ultrasound’s effects on the brain (ultrasound is the type of imaging the transcranial doppler probe uses), it is generally considered very safe and highly useful for diagnosis of many potentially dangerous conditions including stroke. The only significant concerns for the brain that I can find in research include potential tissue damage but this is seen only with prolonged exposure at MUCH higher frequencies than are used in clinical practice, which you can read about here. There does seem to be hope for using ultrasound for chronic conditions including depression and epilepsy. This article gives a nice overview of some of the potential uses in the peer-reviewed journal, Science.

Hope this study turns out to be beneficial for you and others. Best!

While I encourage you to get more information, please note that research on tissue damage was only done in the lab, so again, no clinical use in patients would be at that high of a frequency. I don’t want to cause alarm when there may be no need.

Best!

How wonderful to hear! Thanks for sharing!
