Welcome to Our Parkinson's Place


I copy news articles pertaining to research, news and information for Parkinson's disease, Dementia, the Brain, Depression and Parkinson's with Dystonia. I also post about Fundraising for Parkinson's disease and events. I try to be up-to-date as possible. I have Parkinson's
diseases as well and thought it would be nice to have a place where
updated news is in one place. That is why I began this blog.
I am not responsible for it's contents, I am just a copier of information searched on the computer. Please understand the copies are just that, copies and at times, I am unable to enlarge the wording or keep it uniformed as I wish. This is for you to read and to always keep an open mind.
Please discuss this with your doctor, should you have any questions, or concerns. Never do anything without talking to your doctor. I do not make any money from this website. I volunteer my time to help all of us to be informed. Please No advertisers, and No Information about Herbal treatments. This is a free site for all.
Thank you.

Alzheimer’s, Parkinson’s linked to body’s mishandling of ‘garbage’

February 20, 2017


A new study…may help explain how diseases like Alzheimer’s and Parkinson’s spread in the brain. Sometimes when neurons dispose of toxic waste, neighboring cells get sick.
“Normally the process of throwing out this trash would be a good thing,” says Monica Driscoll, professor of molecular biology and biochemistry at Rutgers University. “But we think with neurodegenerative diseases like Alzheimer’s and Parkinson’s, there might be a mismanagement of this very important process that is supposed to protect neurons but, instead, is doing harm to neighbor cells.”
“What we found out could be compared to a person collecting trash and putting it outside for garbage day,” says Driscoll. “They actively select and sort the trash from the good stuff, but if it’s not picked up, the garbage can cause real problems.”
The roundworms engineered to produce human disease proteins associated with Huntington’s disease and Alzheimer’s threw out more trash consisting of these neurodegenerative toxic materials. While neighboring cells degraded some of the material, more distant cells scavenged other portions of the diseased proteins.
“These findings are significant,” Driscoll says. “The work in the little worm may open the door to much needed new approaches to addressing neurodegeneration and diseases like Alzheimer’s and Parkinson’s.”
