I HAVE PARKINSON'S DISEASES AND THOUGHT IT WOULD BE NICE TO HAVE A PLACE WHERE THE CONTENTS OF UPDATED NEWS IS FOUND IN ONE PLACE. THAT IS WHY I BEGAN THIS BLOG.

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 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. IT IS IMPORTANT TO UNDERSTAND I AM A PERSON WITH PARKINSON'S DISEASE. I HAVE NO MEDICAL EDUCATION,

I JUST WANT TO SHARE WITH YOU WHAT I READ ON THE INTERNET. IT IS UP TO YOU TO DECIDE WHETHER TO READ IT AND TALK IT OVER WITH YOUR DOCTOR. I AM JUST THE COPIER OF DOCUMENTS FROM THE COMPUTER. I DO NOT HAVE PROOF OF FACT OR FICTION OF THE ARTICLE. I ALSO TRY TO PLACE A LINK AT THE BOTTOM OF EACH ARTICLE TO SHOW WHERE I RECEIVED THE INFORMATION SO THAT YOU MAY WANT TO VISIT THEIR SITE.

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 FIRST..

Leave the Brain Out of It: Spinal Stimulation Could Offer an Alternative to Treat Parkinson’s Motor Symptoms

Deep brain stimulation
is a game changer for
many Parkinson’s disease
(PD) patients. This therapy
can alleviate motor
symptoms and improve
quality of life,
but it does require
brain surgery and is not
a possibility for all
people with PD.

A group of researchers
from Duke University
and the Edmond and
Lily Safra Institute of Neuroscience of Natal in Brazil is working toward the same
end result without the need for such an invasive procedure. These investigators
made a splash earlier this year when they published in Scientific Reports
that spinal cord stimulation in pre-clinical models improved motor symptoms
and showed neuronal protection.

The Michael J. Fox Foundation (MJFF) did not fund that study, but we have
funded research from this same group of investigators to test spinal
stimulation in a more advanced model. The MJFF-supported study is
not testing the neuroprotective effect.

“This is an exciting time for, what we call, neuromodulation,” says Maurizio
Facheris, MD, MSc, associate director of research programs at MJFF.
While deep brain stimulation has helped many people living with Parkinson’s
disease, there are limitations to its use. Spinal stimulation could extend this
therapeutic approach to many more.”

For deep brain stimulation (DBS), a surgeon implants a thin electrode into the
brain, targeting motor circuits that are not functioning properly. Small electrical
pulses from a device similar to a cardiac pacemaker block the signals that
cause some Parkinson's motor symptoms. Spinal stimulation uses the same
technique, but rather than blocking the signals where they begin, the therapy
blocks them further downstream. The electrodes are implanted in the dura, the
outermost of three layers that surround the spinal cord.

Spinal cord stimulation is already used to treat chronic pain. Researchers
are fine-tuning the application to work on the neurons that misfire to create
Parkinson’s motor symptoms. If successful, this procedure would be an alternative
for patients who may not be able to have DBS because of vascular problems,
mood disorders or aversion to brain surgery.

Through another grant, MJFF is supporting researchers from the University
of California, San Francisco to develop a method to record brain activity
during DBS so the stimulation can take place only when needed instead
of continuously. The same enhancements could be used in spinal stimulation.
