Active clinical trials for "Parkinson Disease"

Parkinson's disease (PD) is the second most common neurodegenerative disorder in the elderly. In most people, the illness is complicated by co-occurring psychiatric problems such as depression and anxiety. These non-motor concerns negatively affect the course and management of the disease, often leading to poor outcomes for both patients and their families. Despite these deleterious consequences, psychiatric symptoms in PD are both underreported by patients as well as under-recognized and under-treated by health care providers. The primary purpose of this study is to identify and describe barriers to mental healthcare utilization for people with Parkinson's disease. Secondary objectives include the assessment of attitudes and preferences regarding the need for mental health services in the PD community and the acceptability of telehealth interventions as a method for improving access and quality of care. In order to accomplish these aims, participants will be asked to fill out an anonymous survey which will take about 15-30 minutes to complete. To best accommodate PD patients with varying levels of disability, participants will have the option to complete the survey online, on paper, or over the phone. The information obtained from this study will be used to support future treatment development efforts (i.e., phone and internet based interventions, community based trainings with local providers) intended to improve access and quality of mental health care for people with PD. To the best of the investigators knowledge, this is the first study to systematically examine barriers to mental healthcare utilization in PD in a national sample.

Cognitive disorders in Parkinson's disease (PD) are not as obvious as cognitive disorders in Alzheimer disease and their diagnosis tends to be delayed. If neuropsychological assessment of cognitive decline in Parkinson's disease is well established, the thresholds of cognitive testing corresponding to a dementia are unknown. Recently, new diagnosis criteria of dementia associated with PD have been proposed by the movement disorder society. In this study two groups of patients with idiopathic PD will be separated and compared according to their Mini Mental State Examination (MMSE) score (upper or lower than 26). Included patients will have clinically idiopathic PD, will be over 65 years old and will present cognitive complain. Cognitive and mood disorders as well as motor symptoms will be assessed using validated scales and a neuropsychological assessment dispatched in two visits will be performed . Differences in the distribution of data from the two groups of patients will be assessed in statistically analysis with non parametric tests. The purpose of this study is to determine the most effective tests and their threshold value corresponding to a pathological cognitive decline.

Developing technology to increase efficiency and decrease cost of clinical trials. The longterm objective of this project is to use new technologies to sensitively measure, automatically analyze and efficiently manage clinical trial data for Parkinson's disease (PD) and other neurological disorders. This project will focus on developing objective measures of balance and gait because mobility disability and falls are so critical for quality of life in PD. Clinical movement disorders experts will team up with a local start-up business to develop, produce, and test a novel clinical balance and gait assessment tool, the instrumented Timed Up and Go Test (iTUG) for patients with Parkinson's disease. Balance and gait will be measured with wireless sensors worn on the wrists, ankles and trunk while patients stand up from a chair, walk, turn and return to sit on the chair. Accelerations and angular velocities from the sensors will be automatically transmitted, stored, analyzed, and displayed as Mobility Scores on a remote, centralized computer, along with other patient information important for clinical trials. Specifically, this proposal will 1) create a commercially-available, clinical trial system that includes completely wireless sensor technology, a custom-made, user-friendly, computer interface and efficient data management server; 2) develop a mobility score from many potential balance and gait measures and 3) compare the sensitivity of the iTUG compared to traditional clinical tests of balance to changes in PD due to antiparkinson medication. By providing a more sensitive, accurate, and comprehensive method to quickly test and analyze balance and gait, clinical trials to improve mobility in patients with Parkinson's disease and other neurological disorders will be significantly more effective and efficient. This will permit clinical trials in Parkinson's disease to be completed with fewer subjects, shorter duration, and less cost.The current project will accelerate the development of new therapies for Parkinson's disease.

This is an open-label, multicenter, non-interventional, prospective observational study. we collect the safety information of pramipexole over 12w treatment. Parkinson disease patients with different severity who have already used pramipexole could be observed in this study. In the whole observation period, treatment decision was determined by physician and patient completely. The safety endpoint is AE(Adverse Event), SAE(Serious Adverse Event), patient withdraw, laboratory test.

Dystonia is a rare disease leading to a severe handicap. It can be of primary or secondary origin. It is characterized by sustained muscle contractions, frequently causing twisting and repetitive movements or abnormal postures. These disorders are believed to be caused by some dysfunction of the basal ganglia (BG) circuitry, but the mechanisms are largely unknown. A better understanding of the disorder requires significant improvements of its phenomenological description in relation to aetiology. We want to identify specific motor signatures of different forms of dystonia. To that aim, we will ask patients to perform movements of various complexities, while recording chronometric, kinematics and EMG data. The characteristics of the patients' movements will be compared to those of matched control subjects. We will examine abnormal co-activation in distal and proximal muscles to evaluate the characteristics of the loss of selectivity of the motor command in mobile vs. fixed dystonia. Consistency of the motor output patterns will be compared in three groups of patients. We will also study possible cognitive and limbic components of the disease, examining the influence of cognitive and emotional loads on movement production. Eventually we want to refine the criteria used to classify different forms of the disease, thus enabling clinicians to better predict the likely outcome of particular therapeutic procedures.

Parkinson's Disease (PD) is often thought of as affecting movement only. In fact, most patients also experience psychiatric and cognitive symptoms, sometimes from the disease itself, and sometimes as a side-effect of PD medications. The goals of this study are to evaluate the causes, effects, and clinical correlates of psychiatric and cognitive symptoms in PD.

This study will test the accuracy of a new home-use electronic device that measures and records small changes in Parkinson's disease symptoms, such as tremor and impaired movement and speech. The testing is done at home and the results are sent by Internet to the patient's doctor. Detecting Parkinson's disease in its early stages may permit doctors to provide early treatment and slow the rate of disease progression. Patients with early Parkinson's disease (less than 5 years) with rest tremors and bradykinesia (slowness and difficulty of movement) who are not taking medications for the disease may be eligible for this study. Candidates are screened with training and practice in using the home monitoring device over 2-3 weeks. Those who demonstrate proficiency with the device may be enrolled in the study. Participants undergo the following tests and procedures: Baseline Visit Participants' undergo symptoms ratings using the Unified Parkinson's Disease Rating Scale and assessments of memory, thinking and depression. At-home testing Participants begin at-home testing with the monitoring device after the baseline visit and repeat the tests weekly for 6 months. The test information is automatically uploaded to a home computer (provided by the study) and sent to the investigators via Internet. The test procedure is as follows: Introduction questionnaire (1 minute): Participants are questioned about how they are feeling at test time. Pegboard test (4 minutes): At the sound of a tone, the participant moves eight pegs from the right to the left using their right and then left hand. Tapping test (3 minutes): At the sound of a tone, the participant alternately presses two buttons with the right index finger and then the left index finger. Reaction time/movement time testing (3 minutes): At the sound of a tone, the participant moves his or her index finger from one button to the other, first with the right hand and then with the left hand. Digitography testing (4 minutes): At the sound of a tone, the participant alternates between pressing two keys with the index and middle fingers. Speech + Actiwatch tremor data upload (7 minutes): The participant: 1) takes a deep breath and says "ahhh" for as long as possible; 2) is shown a picture and, at the sound of a tone, is asked to tell a story about the picture; 3) uploads the tremor data from the Actiwatch (a device worn on the wrist that records tremors). At specified times du...

The general aim of this non-interventional study is to assess the safety and efficacy of pramipexole extended release in patients with Parkinson's disease in routine clinical practice.

The underlying goal of this study is to assess [18F]MPPF PET imaging as a tool to evaluate the activity of the serotonin 5HT1a receptor in the brain of Parkinson Disease (PD) research participants.
