Dear William, In your post, you describe how your father's condition seems to have worsened in the hospital, as opposed to how he was doing beforehand. I don't have the full solution -- but I can tell you that I was distrubed to see that the doctor had placed your father on a regimen of HALDOL (=Haloperidol). This drug is specifically CONTRA-INDICATED, from what I've read, for a PD patient; it EXACERBATES various PD symptoms. You'll find this information on various of the "Contra-Indicated for PD" lists that have been posted in earlier versions of the PD Digest; you can also seek out more details by doing a search on the Internet, such as by using the search-engine Yahoo.Com or AltaVista.Com; or you can even look it up in the Merck Manual.) So I would immediately bring this to the attention of your father's physician and neurologist. Plus -- since the doctor at the hospital apparently saw fit to administer Haldol in the manner that you described, I would ALSO make a point of carefully reviewing ALL the medications that your father is being given, to see whether or not they're contra-indicated for a PD patient and to see, as well, HOW LONG any negative effects might be expected to last even after that particular drug's administration has been stopped. Good luck. -- SJS
