Hello,  My Dad has had PD for about 13 years and recently was diagnosed as possibly having Normal Pressure Hydrocephalus (NPH), commonly known as "water on the brain".   I know that sometimes people with NPH are *misdiagnosed* as having PD; but given that my dad was diagnosed so long ago and has had MRIs during this period that do not show NPH, we do not think this is a misdiagnosis. Rather it seems to be in addition to his PD.  My question for the group is:  (1) has anyone out there also had both PD and NPH?    and (2) if so, did you have the surgery to place a shunt in the brain to help drain the excess fluid?  I'm interested in hearing about all experiences. If you want to respond to me offlist, I'm glad to compile the responses & post back to the main list  Thanks so much. I've found this listserv to be a valuable source of information; thanks to Diane and Ray and everyone else who shares articles and personal knowledge! ****************************************** Paula Jayne, MPH Doctoral Candidate Department of Women's Studies Emory University Atlanta, GA 30322 ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
