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.

Liquid L-dopa is usually taken as a combination of L-dopa, carbidopa, and ascorbic acid (vitamin C) in a solution called LCAS. Therapy with liquid L-dopa has been used in people with advanced Parkinson's Disease for many years. However, long-term follow-up information is scarce. The present study aimed to determine the long-term retention rate for LCAS therapy, and to identify the causes of LCAS therapy withdrawal.

People with Parkinson's Disease were assessed who had undergone LCAS treatment to alleviate motor complications that were not controlled by optimised conventional Parkinson's Disease treatments. The three main reasons for discontinuation of LCAS treatment were worsening of wearing-off symptoms, persistent dyskinesia, and poor drug adherence. However, there were a small number of each of these. Around 37% of people maintained the LCAS treatment after 12 months. In those people, on time without dyskinesia significantly increased from 33% to 57% after the initiation of LCAS treatment. Around 31% of patients were still receiving LCAS treatment after 30 months.
