What happened with that study where they were using Parkinsons Drugs

[guy123]

There was a study or something where they were using drugs that increase dopamine (which usually makes tics worse) in an attempt to get the brain to adapt by decreasing its sensitivity or responsiveness or something with the idea that over time, the tics would actually decrease as the brain reestablished its concept of "normal"... or something along those lines. Or maybe when the user came off the drugs, then the tics would reduce. Of course, I think the brain would eventually go back to its old levels, so I'm wondering how this study ended up.

 

Does anyone remember the name of the doctor or the study or have the results? I remember reading about it a year or two ago and now I'm curious what ended up happening with it.
