Active clinical trials for "Parkinson Disease"

The gait symptoms are usually refractory to the dopaminergic agents and some other resolutions, i.e. repetitive transcranial magnetic stimulation (rTMS) should be searched for in this regard. To study the impact of rTMS, investigators will adopt a domestically developed ambulatory recorder (PK-16CH EXG) for the concomitant recording of the electroencephalographic and electromyographic signals for PD patients when walking in the gait laboratory or when conducting leg dorsiflexion movement on sitting.

The etiology of many neurodegenerative diseases is unknown. A few studies have suggested the role of infection in the gastrointestinal tract in the etiology and pathogenesis of neurological diseases such as idiopathic Parkinson. For example, infection with Helicobacter pylori has been suggested to play a role in Parkinson disease. In addition, bacterial pathogens such as spirochetes and bacterial products such as cyanobacterial toxins have been speculated as the contributing factors in the development of amyotrophic lateral sclerosis (ALS). The effect of microbial composition of the gut in the pathogenesis of ALS is suspected. The difference in the bacterial profile of the gut has been documented in diseases such as inflammatory bowel disease and obesity. The goal of this IRB protocol is to create a human tissue bank and to obtain patients' demographic information for future investigation of the role of bacterial pathogens and the role of gut flora composition in the development of neurodegenerative diseases including but not limited to ALS, Parkinson's disease, and multiple sclerosis.

Parkinson's Disease (PD) is a neurodegenerative disease characterized by chronic and progressive loss of dopaminergic neurons in the substantia nigra (SN) pars compacta. Sleep disturbances and fatigue are very common problems in Parkinson's patients. He reported that the frequency of fatigue was 47% in patients with a disease duration of less than five years and 70% in patients with a disease duration of more than five years. Fatigue in PD has been found to be associated with decreased physical activity, decreased functionality, sleep disorders, gait disturbances, motor findings, autonomic findings, increased levodopa dose, and motor fluctuations. Motor and non-motor symptoms in Parkinson's patients affect the individual's ability to perform activities of daily living independently. Impairments in functional status lead to negative consequences on quality of life. PD affects the individual not only physically, but also psychologically and socially.The neutrophil/lymphocyte ratio is a marker of peripheral inflammation. The relationship of peripheral inflammation to quality of sleep, quality of life and fatigue in individuals is unclear. The aim of this study was to investigation fatigue, quality of sleep and quality of life, and the relationship between neutrophil/lymphocyte ratio in Parkinson's patients.

This study aimed to examine the relationship of quality of life with tremor severity and upper limb functionality in individuals with Parkinson's Disease. The differences between Parkinson's Disease Quality of Life Questionnaire, Nine-Hole Peg Test, grip and pinch strength values in the individuals with and without tremor in the study were investigated.

Postoperative delirium (POD) remains one of the most common neuropsychiatric complications after deep brain stimulation (DBS) surgery. The fibrinogen-to-albumin ratio (FAR) has been shown to significantly correlate with prognosis of many diseases associated with inflammation, but the relationship between FAR and POD is unclear. The investigators aimed to investigate the association between POD and FAR in Parkinson's disease (PD) patients receiving DBS surgery. For this aim, the present study was conducted to provide a new method for the early recognition and perioperative management of delirium after DBS surgery in PD patients.

The investigators are examining how aspects of daily function are perceived in persons with PD and in those who interact with them on a regular basis. If eligible, participants will receive a set of online questionnaires by email. The questionnaires will take about 1 hour to complete, and can be done at the participant's convenience. The investigators are looking for volunteers who have a diagnosis of Parkinson's disease without dementia (age 40 or older and proficient English speakers). If a spouse, family member, significant other or other close associate is available (age 18 or older, proficient English speakers), the investigators will send them questionnaires as well. There is no monetary or other compensation for this study. For more information, please contact the Vision and Cognition Laboratory at vcognition@gmail.com or 617-358-1377.

The objective of this study is to describe the evolution of hypodopaminergic syndrome in patients with Parkinson's disease.

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.

Apathy can be defined as a quantitative reduction of voluntary or goal-directed behavior. So, the investigators propose a behavioral approach for assessing apathy, to obtain a quantifiable and objective signature of reduced goal-directed behavior by directly observing a patient in a real-life situation. ECOCAPTURE consists of a multi-step scenario in a functional exploration platform equipped with data acquisition system based on video and sensors that track a participant's behavior. The primary objective of this trial is to create a diagnostic tool for apathy, based on the video and sensors metrics. A secondary objective of this trial is to validate a new experimental task (ICM_APATHY_TASKS) to test independently three main presumed mechanisms of apathy (motivation, cognitive inertia and coupling between motivation and action). Another secondary objective aims to specify the pathophysiological mechanisms of apathy, corresponding to cognitive and behavioral processes, neural bases and neurohormonal mechanisms. The definition of pathophysiological mechanisms will allow the classification of apathetic patients (or several forms of apathy) and indicate which mechanism (s) best explains the apathy in a given patient.

The overall goals of this proposed study are to investigate the behavioral and neurophysiological mechanisms of patients with Parkinson's disease (PD) experiencing freezing of gait (FoG). More specifically, we aim to determine the behavioral changes in context-dependency and changes in corticomotor excitability associated with FoG.
