Parkinson's Disease With Voice Dysfunction Patients
• Twenty people with Parkinson's Disease requiring evaluation of voice dysfunction by an Ear, Nose, and Throat (ENT) doctor Cytology and Immunohistochemistry: Determine if nasal swabs can provide an adequate sample for evaluation using cytology and immunohistochemistry for alpha-synuclein, A-beta and p-tau staining.
Other Neurodegenerative Disorders With Voice Dysfunction

Measure
Parkinson's Disease With Voice Dysfunction Patients
n=4 Participants
• Enrollment was stopped due to COVID-19 pandemic after 4 people with Parkinson's Disease requiring evaluation of voice dysfunction by an Ear, Nose, and Throat (ENT) doctor were enrolled. Cytology and Immunohistochemistry: Samples from 1 subject were processed for GFAP and S100 staining to confirm presence of olfactory neuronal tissue.
Other Neurodegenerative Disorders With Voice Dysfunction
n=5 Participants
• Enrollment was stopped due to COVID-19 pandemic after 5 people with other neurodegenerative disorders requiring evaluation of voice dysfunction by an ENT doctor. Cytology and Immunohistochemistry: No samples were processed for this group.
Voice Dysfunction
No subjects were enrolled in this arm.

PRIMARY outcome

Timeframe: Up to 4 weeks after swab is completed

Population: Due to early termination of subject enrollment, there were an insufficient number of samples to process for this analysis. As such, none of the samples were (or will be) analyzed for the outcome measures listed and therefore there are no results to report beyond participant flow.

Determine if nasal swabs can provide an adequate sample for evaluation using cytology and immunohistochemistry for alpha-synuclein, Amyloid-beta (A-beta) and Phospho-tau (p-tau) staining.
