Thanks. > Bryce Jones > Hello Bryce, Cogentin is a drug belonging to the group called 'anti- cholinergics. These drugs reduce the amount of acetylcholine in the brain, which apparently allows a little more dopamine to get through. They are sometimes used to control tremor and slowness of movement, but by today's standards they are not very good at it. Anticholinergics come with a list of potential side-effects as long as your arm, and are not recommended for elderly people because of the tendency to cause confusion. The good news is that there are more modern , and more effective options available. Try your doctor on Permax, for instance. Regards Brian Collins <[log in to unmask]>
