The Gut in PD is Messed Up


There is no question that the PD gut is different from healthy controls, and now there are dozens of tests available to identify abnormal "gut stuff" linked to Parkinson's.

What should you be tested for?

What should you do with the results?

What is a waste of money?


H. Pylori


H pylori infections have been shown to CAUSE parkinsonism and eradication of the infection improves outcomes. Why isn't everyone tested?

SIBO

Small Intestinal Bacterial Overgrown (SIBO) impacts more than half of patients with PD-- impacting medication absorption and even symptoms. How to test? How to treat?

"Leaky Gut"



Testing for Intestinal Permeability is available with a simple urine test. Who and why should a person consider testing?

Intestinal Microbiome


We know you have dysbiosis (wrong bugs growing) -- should you test to see which ones? How important is shotgun sequencing?




Short Chain Fatty Acid


Without butyrate and other SCFA, the cells that keep the intestine healthy die. How can you test yours?



Urinary Indican


How much protein putrification is occuring in YOUR gut? Are you getting enough fiber? Urinary indican tests are quick and easy...


Urine Organic Acids

One urine test can provide a lot of information about the bacteria and fungus in your body-- how to tell if it is coming from the gut?

Burp Test


Heidelburg testing for HCl deficiency is gold standard, but much of this information might be available for free from home.

Food Allergy Testing


Why does nobody talk about the potential for of food allergies and immune-system activation in PD? Should you be tested?

Mischley Seminar Series


On the 28th of every month, Dr. Mischley selects a topic relevant to the community and does a in-depth review. Following her lecture, attendees have an opportunity to contribute their own experiences and ask questions.


These courses are information dense!

Lecture slides, references, and session recordings are made available for those who want to rewind or take breaks.

About Dr. Mischley

Laurie Mischley, ND PhD MPH studied naturopathic medicine (ND) at Bastyr University and epidemiology (MPH) and nutritional sciences (PhD) at the University of Washington and she maintains appointments at both Universities. Her work is focused on identifying the nutritional requirements unique to individuals with Parkinson’s Disease (PD) and has published on coenzyme Q10, lithium, NAD+, and glutathione deficiency.

She is Principal Investigator of the Modifiable Variables in Parkinsonism (MVP) Study (MVP-study.com), which is attempting to describe why some people with PD progress slower than others. She developed the Patient Reported Outcomes in PD (PRO-PD) rating scale (www.PD-symptoms.com), created the Parkinson Symptom Tracking App, and has trained dogs to detect the scent of Parkinsonism (ParK-9.com).

She is working on ways to study, package and deliver evidence-based lifestyle modification as a therapeutic strategy.
