Different types of DBS

Hi All,

Having recently been assessed for DBS at John Radcliffe, I have been advised that STN DBS might pose significant threats due to my depression and impulse control disorder (both of which were side-effects of certain Parkinson's drugs).

They have recommended GPi DBS which, I believe, is very similar to STN but in a different area of the brain. Has anyone been along this route?   I would appreciate any advice.

Many thanks,
