HI Martha, Your provocative test for PD makes a lot of sense theoretically but individuals respond so differently to drugs, I'm afraid that it wouldn't be practical. Some people become severely dystonic on relatively low doses of neuroleptics- that who are not developing PD. These people almost always respond to an anticholenergic like cogentin artane or benadryl. Your logic is flawless but other factors probably make it impractical as a diagnostic test.
