Good afternoon Joe. Your information was very helpful. I'm still considering whether to do HIFU or DBS. DBS is more invasive from what I've researched. HIFU, although less invasive, seems to have more risk. Because it can cause irreversible damage, as you mentioned, just by a few millimeters. Another factor is whether my symptoms will actually improve with HIFU. I'm evaluating all of this with my neurologist. Thank you very much for your feedback.
