Filter by:The purpose of this study is to examine the brain changes in people with Parkinson's Disease (PD) after they get deep brain stimulation (DBS) surgery, compared with people who do not have Parkinson's Disease. Treatment of Parkinson's disease is often difficult and challenging. Deep brain stimulation is an established surgical treatment that is effective for the treatment of PD, but the details of why it helps are not known. In order to achieve maximum benefits from this treatment, it is important to understand how it changes the brain. Specifically, the investigators will study electrophysiology, which is the study of how the brain conducts electrical messages to the rest of the body. To do this, the investigators will use transcranial magnetic stimulation (TMS), which is a painless and non-invasive procedure. They will also conduct motor physiology experiments of the upper and lower limbs to collect data about skeletal muscle movement. The data from this study will help explain whether the electrical changes in the brain have any relation to the physical benefits patients with Parkinson's Disease sometimes receive from DBS surgery.
AIM: Investigate wether there are differences in the parasympathetic nervous system in Parkinsons patients compared to controls. MATERIALS AND METHODS: We use the tracer [11C]donepezil to image the parasympathetic nervous system. The Investigators will include 20 Parkinsons patients and 20 healthy controls aged 40-80 in our study. The participants will receive a careful medical examination, including a neurological examination, as part of the inclusion process. The subjects also have an MRI scan of the brain. Then PET/CT scans with [11C]donepezil are conducted - once for the upper abdominal region and once for the head region. For evaluating the function of the parasympathetic nervous system gastric emptying time, heart rate variability and salivary flow will be measured. These measureless will be correlated to the PET findings. PERSPECTIVES: The study will potentially result in the development of a PET ligand for imaging the parasympathetic nervous system. This will have applications for research in Parkinson's disease, diabetes, heart disease and other disorders, in which the autonomic nervous system is involved
The purpose of the study will be to determine the effects of the Cognitive Orientation to daily Occupational Performance (CO-OP) as a treatment program for individuals with Parkinson's disease-related cognitive impairment. The potential effects of the CO-OP on successful engagement in meaningful activities will be examined from participants' and live-in caregivers' perspectives. Effects of the CO-OP on participant-perceived health-related quality of life and caregiver burden will also be evaluated. Hypotheses: 1. Training with the CO-OP will have an effect or multiple effects on participation in meaningful activities and health-related quality of life for individuals with Parkinson's-related cognitive impairment. 2. Training with the CO-OP will have an effect or multiple effects on caregiver burden and health-related quality of life for caregivers of individuals with Parkinson's-related cognitive impairment.
The B7441003 study will assess PF-06412562 for motor benefit in Parkinson's disease subjects. Safety, tolerability and PK of PF-06412562 in Parkinson's disease subjects will also be evaluated.
The primary objective of the trial was to investigate the efficacy of apomorphine continuous subcutaneous infusion compared to placebo in Parkinson's Disease patients with motor fluctuations not well controlled on medical treatment. The secondary objective of the study was to investigate the safety and tolerability of apomorphine continuous subcutaneous therapy.
Gastroparesis (slow stomach emptying) is a common feature of Parkinson's Disease. Levodopa (Sinemet), a common medication for Parkinson's Disease, can make gastroparesis worse. Gastroparesis effects how the levodopa is absorbed and used by the body. This study will explore the possibility of using Erythromycin, a drug commonly used (off label) for gastroparesis, along with levodopa to determine if there is improved levodopa absorption and motor function.
Parkinson's disease (PD) is the second most prevalent neurodegenerative disease. The investigators clinical experience showed a trend of delayed emergence among patients undergoing deep brain stimulator (DBS) implantation and pulse generator placement under general anesthesia. Abnormal pharmacodynamics might be present among these patients, which had never been investigated.
There is a growing trend in functional neurosurgery toward direct anatomical targeting for deep brain stimulation (DBS). This study describes a method and reports the initial experience placing DBS electrodes under general anesthesia without the use of microelectrode recordings (MER), using a portable head CT scanner to verify accuracy intra-operatively.
To observe and analyze the correlation between Single Nucleotide polymorphisms (SNPs) and the incidence of Parkinson's disease in Taiwanese.
Parkinson's disease (PD) is one the main neurodegenerative disease with an incidence of about 3% in patients older than 65 years. Anesthesia in PD patients has been focused by several studies for concerning the interactive reaction between anesthetics and anti-Parkinsonian medication or Parkinsonian symptoms. However, our previous experience showed that the patients undergoing pulse generator placement were more prone to be involved in delayed emergence in the recovery room, which had been not reported yet. We speculated that PD patients might be a special population with abnormal pharmacodynamic characters of anesthetics, though no related evidence could be found to support this hypothesis. Therefore, in this project we investigated whether remifentanl requirement to inhibit patients' response to trachea intubation and skin insertion in PD patients undergoing DBS and pulse generator placement was different from non-PD patients undergoing intracranial surgery for reasons other than PD.
