I think it depends on the person. My mom's experience isn't that uniform. Every MDS sees her high pulse width (for PD I guess), is like "Hold my beer.", and tries something that works out worse than the settings she's had since she first got DBS in 2005. It is night and day for tremor, but it also has significant trade-offs. Granted, it could be that the targeting wasn't ideal to begin, after 15+ years she needs her leads redone, or something else, but from what I've seen it really is a set of trade-offs. I remember watching a video by a guy who just got DBS talking about something similar with a researcher and I'll edit this post if I can find it.

it is hard to say...anecdotally, I've seen generally that the further the electrode is located away from the posterior subthalamic nucleus, the higher the PW is needed to achieve any effect. Maybe the electrode probably needs it to send current over further distances. But it may be helpful to map things out if imaging is available. Targeting has probably come a long way too. I remember pulling old MRI's from cases done in 2003 or so, and they just look so fuzzy and crude compared with modern machines...
