Gina---Good morning Cogentin has done right by me. But it is notorious for causing or contributing to the cause of memory loss. For me it was the only thing i could count on to help me with the serious dystonicb pain i use to have.(This major pain was relieved by a unilateral pallidotomy, It only takes a small dose of cogentin to help immensely. It also helps some people with rigidity Hope you have a real good day!!!!!!------pete
