This study will explore the relationship between multimodal brain MRI findings and cognitive/mood outcomes in Parkinson's Disease (PD) patients following Deep Brain Stimulation (DBS). Patients already planning to undergo DBS for PD who choose to take part in this study will have study visits before and after DBS to collect motor, neurobehavioral and physical therapy measurements.

Patients who are already planning to undergo DBS for PD who choose to take part in this study will have study visits before and after DBS surgery to collect motor, neurobehavioral and physical therapy measurements. While many of these components are part of as standard of care, some assessments will need to be collected specifically for research purposes. There are two in-person visits (one before DBS surgery and one approximately 3-6 months after surgery). As part of the study, an MRI to gather data to answer our research questions will be conducted. This is in addition to the clinical MRI that is part of the regular assessment to determine if an individual is suitable for the DBS surgery.

This research is being done to study the deterioration of the central olfactory system (sense of smell system) in the brains of patients diagnosed with early- stage Parkinson’s disease.

This research is being done to study the deterioration of the central olfactory system (sense of smell system) in the brains of patients diagnosed with H&Y stage 1 or 2 Parkinson’s disease compared to that of healthy volunteers.

In this study, you will receive a clinical evaluation and an MRI examination. After that, you will be followed every 12 months for up to 4 years.

The purpose of this study is to use fMRI to identify and characterize the olfactory, auditory, visual and trigeminal-related brain networks. This research will then be use to enhance human health by laying the foundation to develop sensitive biomarkers to identify people who are at risk of developing brain disorders such as Alzheimer’s disease and Parkinson’s disease, where olfactory deficits are known preclinical symptoms.

The purpose of this study is to collect normative data related to orofacial (lip/tongue) somatosensation (touch sensation) in healthy adults across the adult lifespan. This data will be compared to a select clinical population, those with Parkinson's disease.

There will be one data collection session lasting approximately 90 minutes. Participants may be invited back for a second session approximately 4 weeks later to repeat the testing sessionDuring the sessions, participants will answer a series of questions about their eating and drinking preferences, they will be asked to provide a speech sample by repeating a series of syllables, words, and sentences, as well as providing a spontaneous speech sample.All participants will be asked to complete a series of sensory tests where small plastic objects are placed on their lip, tongue, and finger tip. Participants will be asked when they feel the pressure/texture and when they do not.
