@Jammer, you've probably shared your experience with DBS many times, but since it's highly relevant to the discussion about Neurosoft, would you mind sharing it again here? Did you receive an implant? Was there any electrical stimulation involved in your procedure? And was your experience positive or negative?
I was part of a clinical study at the San Francisco VA. Before surgery, I underwent several pre-surgical evaluations, including hearing tests, cognitive assessments, and an fMRI. I had DBS implantation surgery on June 26, 2016, which involved placing a stimulator in my chest and two brain electrodes.
About a month later, I met with the team and received my handheld controller, training, and data collection documents, and I began stimulation. My tinnitus had been mild to moderate for about 15 years and had slowly worsened over time due to accumulated acoustic trauma.
I recorded my response to each setting after three days, then changed the stimulation settings according to the test instructions. This continued for several months, with changes every three days. I never noticed any difference, positive or negative, in my tinnitus.
I met with the team again to review the data, and they decided to try higher voltage settings. After another five months, my tinnitus had gradually become more severe. I then took a break and turned off the stimulator, with the team's approval, to see if the increase in tinnitus would resolve.
Unfortunately, my tinnitus continued to worsen. I also noticed that the leads connecting the stimulator to the brain electrodes were tightening and causing discomfort, likely due to scar tissue forming around them.
At seven months, the system was explanted, and I discontinued my participation in the study. It took several years for the thick scar tissue in my neck to dissipate, and only then could I rotate my head without discomfort. My tinnitus kept worsening, and I eventually had to retire from my career as a medical device engineer, especially after being exposed to a pneumatic hammer drill at work (even while wearing earplugs). I could no longer focus or remain effective. I was 58 at the time.
This was an extremely disappointing outcome for me. Having been a medical device engineer for over 20 years, I understood how pivotal human clinical trials are in bringing new devices through FDA approval and into successful commercial use.
I am now at a catastrophic level and struggle to find enjoyment in life. Acceptance and the love of my family are what keep me going.
