More than 10 million people worldwide are living with Parkinson's disease (PD). While the actual number of African American (or Black) patients with PD is unknown, it is clear that there are racial disparities in the access to health care, diagnosis, treatment and survival of PD. The lack of clear knowledge on the possibly lower PD prevalence among African Americans compared to Caucasians further calls for more research in this field. The University of Chicago Medicine is an ideal facility to study this topic, due to its location on the South Side of Chicago with a large African American (or Black) population. By analyzing the demographics, socioeconomics and clinical features of PD patients in our Center for Research Informatics in African American (or Black) patients compared to the Caucasians of similar geographical area, the investigators aim to work toward a better understanding of the unique features of PD in American American (or Black) population, which might help improve the healthcare among this population in the Chicago and possibly nationwide as well.
Non-motor symptoms (NMS) are common in Parkinson's disease (PD) and cause significant distress and decreased quality of life. A high rate of non-declaration of NMS by patients means that many NMS remain unrecognized and untreated, even in specialist clinical services. In phase one of this research qualitative interviews (phase 1) were guided by the Theoretical Domains Framework and used to identify the barriers for help-seeking. A quantitative questionnaire survey (phase 2) examined the significance of these barriers to help seeking. The present study aims to develop (phase 3) and test the feasibility (phase 4) of a targeted behavioural intervention of barriers which were identified in phases 1 and 2 which prevent help-seeking for NMS in patients with PD. As with phases 1 and 2, the feasibility trial will include people with unreported burdensome NMS, who have not reported them to their PD consultant or nurse. The intervention has been co-designed by people affected by Parkinson's and targets the barriers identified in the previous phases of the research. In phase three of the research, 'think-aloud' interviews will be used to further develop the intervention so that it is acceptable and easy to use. In the final phase, a feasibility trial will be conducted to examine efficacy of the intervention for increasing help-seeking for undeclared NMS. The study has implications for using a theoretically driven behavioural intervention to promote help-seeking for NMS and ultimately increase receipt of clinical care for NMS among patients with PD.
Freezing of gait (FoG) is a common and debilitating condition in Parkinson's Disease (PD) patients. FoG is described as an episodic inability to walk, which often triggers falls, hospitalization and is an important predictor of poor quality of life. As locomotor regions degenerate in PD, gait automaticity is impaired. Patients compensate by increasing volitional control of gait, however, this adaptation has been found to worsen FoG severity. We hypothesize that increased cortical control of gait is maladaptive, and therapies to improve gait automaticity will not be effective unless cortical control of gait is reduced. The long-term goal of this project is to develop a therapeutic approach for FoG that simultaneously reduces cortical control and increases automaticity of gait. The objective is to determine the locomotor network abnormalities responsible for FoG and demonstrate how neuromodulation and rehabilitation can modulate the network. The rationale of this study is that increased connectivity between brainstem locomotor regions and cortical structures represents increased cortical governance of gait, and it can be reversed by the proposed intervention. We will accomplish this by combining a course of inhibitory rTMS (1Hz) to the cortex (supplementary motor area) with a rehabilitation protocol designed to increase gait automaticity (dual task training). We have designed a study that will carefully assess the locomotor network of freezers with resting state functional, diffusion and interleaved TMS/BOLD MRI studies, before and after intervention. Behavioral measures including gait analysis, cognitive and motor assessments will also be conducted at baseline and post treatment. The study aims to determine the effects of our intervention on the locomotor network (assessed with imaging), as well as on FoG severity as quantified through multiple markers obtained through gait analysis. At the conclusion of the study we expect to have determined the network changes central to the pathophysiology of FoG, the effects of 1Hz rTMS + rehabilitation on this network, and on FoG severity. The relevance of this study to public health is to develop a non-invasive effective therapeutic option for one of the most debilitating and untreatable conditions affecting the lives of one million Americans suffering from PD; freezing of gait.
This is a study of single ascending intravenous doses of MEDI1341 or placebo in up to 48 healthy volunteers, aged 18 to 65 years. The study will include up to 6 planned cohorts; each cohort will comprise 8 participants. Each participant will receive a single 60 minute intravenous infusion of MEDI1341 or placebo and will undergo scheduled assessments over a period of 13 weeks. The main aim of the study is to assess the safety and tolerability of single doses of MEDI1341 in healthy volunteers.
Patients with Parkinson's disease have internal rhythm dysfunction, which may affect the rhythmic movements such as walking. Poor regularity of the rhythmic movement may lead to freezing of gait. This study will apply rhythmic auditory cues on the stepping-in-place training and the investigators will examine if the behavior and neuroelectrophysiology would change after auditory cueing training. The investigators hypothesize the variation of rhythmic movements such as walking and stepping-in-place will be reduced, and the cortical excitability would be modulated after training.
The purpose of this study is to measure neural activity during deep brain stimulation (DBS). There are two types of neural activity that we will record from DBS electrodes during this study: DBS local evoked potentials (DLEPs) and spontaneous, local field potentials (LFPs). We will measure the effects of varying stimulation parameters on both the neural activity and changes in motor symptoms -- bradykinesia and tremor -- in subjects with Parkinson's disease (PD). Correlating neural activity characteristics with changes in symptoms will improve our understanding of the mechanisms of action of DBS. This intraoperative study will specifically compare our ability to record neural activity using circuitry developed at Duke for this purpose [Kent et al, 2015] to a new, implanted pulse generator (IPG; RC+S) developed by Medtronic. These intraoperative studies will specifically test a preliminary version of the RC+S (that is not designed for implantation), and will lead to a clinical trial assessing the efficacy of the implantable RC+S IPG in PD patients once this device is available and approved for this trial.
The overall goal of this T2 translational research project is to pilot an interdisciplinary high-intensity group singing program to improve speech and swallowing in patients with Parkinson's Disease (PD) and to explore the impact of this program on quality of life (QOL). This research has three specific aims: 1) Determine the effects of a high-intensity group vocal training program on vocal function and laryngeal structure; 2) Determine the transference of vocal training to laryngeal aspects of swallowing; 3) Determine the effect of patient-reported changes in Quality of Life (QOL) as the result of participation in a group vocal training program. Twenty patients with Parkinson Disease will be recruited from the Fresco Institute for Parkinson's & Movement Disorders to participate in a 12-week vocal training program. The program will train participants using maximum vocal function exercises targeting vocal deficits specific to PD. Choral singing therapy sessions will be conducted once weekly with daily home practice exercises based on principles that have been successful in other intensive PD vocal exercise programs.
This is a Phase I/II randomized, double-blind, placebo-controlled, multiple rising dose study in patients with stable idiopathic Parkinson's disease (PD) to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of ITI-214.
The purpose of this study is to determine how using auditory cues of a metronome and music at various frequencies impacts the gait mechanics in people with Parkinson's disease when walking over ground and on a treadmill. The investigators will enroll a total of 40 participants: 30 subjects with a diagnosis of Parkinson's disease (10 in Stage 1, 10 in Stage 2, and 10 in Stage 3) and 10 unimpaired subjects. Participants will complete 7 different treadmill walking conditions and overground walking conditions while the investigators measure step length, cadence, gait speed, and variability of movement.
