Guest guest Posted December 1, 2011 Report Share Posted December 1, 2011 Hi Tania I'm glad nan suggested that PDD and LBD Are pretty much the same - My mother showed park symptoms first then cognitive problems including delusions and no hallucinations - due to the rapid decline the neurologist said it wasn't just parkinsons and suggested she had LBD /PDD ! I researched the two extensively and found that as Nan suggests the two are pretty much the same - and are noted to move more rapidly than patients that have either or - Parkinsons- dementia ! Did the neurologist explain that the two are prettying the same?? Judy R.

He had Parkinson's for many years and the dementia came much later. There is no difference between PDD and LBD except for the brain areas that are hit. In PDD, the brain has changes due to Alpha Synuclean Proteins being laid down in the areas that control movement. If those same proteins occur in the cortex it is called Pure Lewy Body Dementia. If it occurs all throughout the brain it is called Diffuse Lewy Body. My husband had no hallucinations or delusions until a year before he died. That's because it took that long for the brain to lay down the proteins in the area of the brain that the hallucinations came from. Same protein. different area. PDD is under the umbrella of Lewy Body Disease. Nan > > > > > > > > We took Dad (dx Parkinson's in 2010, then LBD early 2011) to Sydney > > today to see a new neurologist today.

Guest guest Posted December 2, 2011 Report Share Posted December 2, 2011 Hi Robin, Thank-you all of you for clearing up the confusion in the terminology used in this disease and to you Robin for clearing up the differences in proteins involved. In 2001 I took an advanced neuro class at Penn State and I don't remember the alpha synuclean proteins even being discussed, only the amyloid protein deposits of Alzheimers were discussed. My question is when our loved ones have a brain scan done, and the doctors talk to us about " white areas " , are these the protein deposits they're talking about? I know from reading many messages on this site that only a brain autopsy definitively determines if (using your term) Lewy body disease is present. Could they be seeing both kinds of proteins? If so, they would need to be treated differently. It seems we have a long way to go in treating this disease when it's so hard to even get a diagnosis.

Both can be called " diffuse Lewy body disease. " One difference is that DLB frequently co-occurs with Alzheimer's Disease so there would be beta-amyloid deposition in DLB. Neuropathologists do not use the term " Lewy body dementia " when addressing pathologic characteristics of a disorder. Perhaps one can make an argument that PDD starts in the brain in the substantia nigra and works its way out to the cortex and DLB starts in the cortex and works its way in, but I'm not sure if we know enough to state that definitively. My impression is that we don't yet know how Lewy body disorders evolve over time in the brain. Robin > > My husband passed away in May.
