Speech, Linguistic and Acoustic Markers in Parkinson's Disease (SLAM-PD)
September 26, 2023 updated by: Kara Smith, University of Massachusetts, Worcester
The Investigators aim to identify speech and language markers that provide information on cognitive function and predict cognitive decline in Parkinson's disease.
The Investigators will administer speech tasks and cognitive assessments to participants with Parkinson's disease and healthy controls.
The Investigators will also explore the associations between genetic factors and speech and cognitive status in Parkinson's disease.

Parkinson's Disease
Subjects with Parkinson's Disease
|
Participants will be asked to complete a series of cognitive testing (testing of concentration, memory, and other thinking abilities).
Participants will be asked to perform speaking and reading tasks, which will be recorded.
Participants will be asked to complete a laptop-based test of language comprehension.
Participants with Parkinson's disease will complete an examination of their symptoms and questionnaires assessing disease symptoms, mood and activities of daily living.
Healthy controls participants will be asked to complete questionnaires on mood.
Participants will have their blood drawn for DNA analysis.
|
Control
Subjects without Parkinson's Disease
|
Participants will be asked to complete a series of cognitive testing (testing of concentration, memory, and other thinking abilities).
Participants will be asked to perform speaking and reading tasks, which will be recorded.
Participants will be asked to complete a laptop-based test of language comprehension.
Participants with Parkinson's disease will complete an examination of their symptoms and questionnaires assessing disease symptoms, mood and activities of daily living.
Healthy controls participants will be asked to complete questionnaires on mood.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Detection of speech acoustic parameters that classify PD participants by cognitive status (mild cognitive impairment [MCI] vs. normal cognition)
Time Frame: 12-24 months
|
Gaussian regression modeling and other machine learning techniques will be used to develop a model including fundamental frequency, noise-to-harmonic ratio, cepstral peak prominence, formants, phoneme-dependent speaking rates and diadochokinesis rate and quality to predict categorization of PD participants by disease and cognitive status.
|
12-24 months
|
Duration and location of pauses during speech in PD participants with and without mild cognitive impairment
Time Frame: 12-24 months
|
Participants will produce speech samples of spontaneous speech, which will be transcribed and coded for pause length and location, and these characteristics will be entered into a non-linear mixed model with the three-level predictor of group membership (control, PD-MCI, PD with normal cognition) as the parameter of interest.
|
12-24 months
|
Syntax processing efficiency score (percentage correctly understood sentences/processing time) in controls, and in PD with and without MCI
Time Frame: 12-24 months
|
When presented with sentences of varying syntactical complexity in a self-paced task, participants response time and accuracy will be used to create multilevel models and test for effect of group (controls, PD, PD-MCI).
|
12-24 months
