DBS was wonderful for me! Stopped all tremors two and a half years ago, and I am on no meds!

If your meds are having no effect on your PD especially Levodopa, then DBS will have little effect on your PD. DBS should only be performed on patients are having a good response to levodopa

I’ve had bilateral DBS. It was the best decision I’ve ever made! However, each case is different. I had success with Sinemet but had started having dyskinesia. I did get an infection after my first surgery, and had to have it removed. This was a minor setback in the scheme of things, after 6 weeks of antibiotics I was cleared to have it again. Then a few months later I had the other side done as well. I can only speak for my experience, which is wonderful! I feel like I have my life back!

I have heard (from my doc amongst others) that if pd meds aren’t effective then dbs isn’t useful. The dbs will only give you a similar effect to the best effect sinemet gives you.

You can find a great deal of information about DBS by reading many conversations about it. Here's a search here that I did - will give you more info. https://www.myparkinsonsteam.com/questions/sear...
