This study (Dopamine D3 receptor agonists for protection and repair in Parkinson's disease). goes on to say that Mirapex has a neuroprotective and neurorestorative effect. From what I read on this forum Mirapex has a lot of side effects and is nearly impossible to get off of. I am amazed it has the ability to help reverse PD.
Apparently a D3 receptor agonist ( Mirapex and others such as ropinarole and7-OH-DPAT) has this restorative effect.
Even so, I am still scared to take Mirapex due to potential side effects. But, those that are on it already may be getting better then they thought.
