Why Oral Health Matters in PD


• Oral–systemic connections (neuroinflammation, cardiovascular risk, microbiome)

• Parkinson’s-specific vulnerabilities: dysphagia, dry mouth, decreased dexterity, altered microbiome

• Goal of session: move beyond “teeth” into whole-body health




The Intestinal Tract Starts in the Mouth

Saliva as the first digestive fluid (enzymes, immune factors)

Oral–gut axis: how oral microbes influence gut microbiota and systemic inflammation

Role in alpha-synuclein misfolding and neurodegeneration

Oral Microbiome & Biofilms


Composition of the oral microbiome in health vs. dysbiosis

Biofilm formation: protective vs. pathogenic states

Influence of oral dysbiosis on systemic inflammation and progression of PD


Clinical Challenges Specific to Parkinson’s

Tremors during exams: patient safety and dentist ergonomics

Reduced manual dexterity → hygiene support strategies

Dysphagia and aspiration risk during dental procedures

Medication-induced xerostomia and caries risk

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.
