PRIMARY outcome

Timeframe: baseline

Population: The entire baseline cohort was analyzed (n=49). Per pre-specified exclusion criteria, one participant determined to have dementia (n=1) was excluded from outcome measure analysis reporting, thus the outcome measure data represents n=48 participants.

Mild cognitive impairment classified by Movement Disorders Society Task Force Level II Critieria

Outcome measures

Outcome measures
Measure
Parkinson's Disease
n=49 Participants
Subjects with Parkinson's Disease Cognitive Battery: Participants will be asked to complete a series of cognitive testing (testing of concentration, memory, and other thinking abilities). Voice, Speech and Language Analysis: 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. Questionnaires and Clinical Assessments: 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. DNA Analysis: Participants will have their blood drawn for DNA analysis.
Control
n=9 Participants
Subjects without Parkinson's Disease Cognitive Battery: Participants will be asked to complete a series of cognitive testing (testing of concentration, memory, and other thinking abilities). Voice, Speech and Language Analysis: 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. Questionnaires and Clinical Assessments: 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.
