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. Please no advertisements.
This is a free site for all.
Thank you.

March 27, 2017

People with Parkinson's Disease are known to be at a higher risk of malnutrition. The prevalence of malnutrition in Parkinson's Disease has been estimated to be up to 24%. Between 3% and 60% of people with Parkinson's Disease are reported to be at risk of malnutrition. To date, there is no clear explanation for malnutrition in these patients.

The aim of this study was to determine the prevalence of malnutrition and the factors that cause it. Of the patients they assessed, 55% of them were at risk of malnutrition, and 8% of them had already been malnourished. Age, Parkinson's Disease severity, off periods, depression and hypothyroidism were the factors most related to developing malnutrition. The dopamine agonist ropinirole was one of the factors that was most associated with a more favourable nutritional status.

Dopamine, whose deficiency causes Parkinson's Disease, is made from dietary substances, including vitamins, minerals and L-tyrosine, which is usually obtained from high protein foods. The deficiency of any of these nutrients could consequently lessen the amount of dopamine produced. The malnutrition that is common in Parkinson's Disease could therefore not only contribute to its onset but could worsen the symptoms over time even further.
