RE: Cognex and PD--I asked the widow of a man in our support group re: their experience. He was Dxd first with AD, then with PD. She said he was on Cognex for 2 years and toward the end of his life the dementia was so much the worse problem that she paid less attention to the PD. However, upon reflection, she feels that Cognex did modify his tremor and rigidity somewhat. She cautions that it requires careful monitoring of the effect on the liver, and not all people can tolerate it. Just another view, FWIW.
