Rica, I saw your question on High Focused Ultrasound (HIFU) which I have begun to investigate at the University of Pennsylvania in the US. I believe this is also referred to as guided ultrasound. The issue is this treatment is permanent. Once the focused area of the brain is destroyed (unilateral strategic injury) it cannot be reversed so the physicians need to be certain of the targeted area and be certain this treatment will improve your symptoms. My wife instead had Deep Brain Stimulation (DBS) surgery five years ago which is a more invasive procedure (brain surgery) but can be moderated once completed to fine tune the targeted area for improved results. She has improved significantly and consistently for the past five years.

Hope this helps, Joe
