Lovastatin as a Neuroprotective Treatment for Early Stage Parkinson's Disease
Parkinson DiseaseBackground: Recent evidence has shown that statins, especially lipophilic statins, may have a neuroprotective benefit in Parkinson's disease (PD). We aim to perform a randomized placebo-controlled trial evaluating the disease-modifying efficacy of lovastatin in patients with early stage PD. Methods and Study Design: This study will be a phase II, single-center, double-blind, randomized, placebo-controlled parallel-group study. In this trial, we are going to examine the possibility that lovastatin, a highly potent lipophilic statin, has disease-modifying effects in PD. We are going to enroll 80 patients with early stage PD patients. Subjects will then be randomized to a 48-week double-blind treatment period of lovastatin 80mg/day or placebo. Primary endpoints are changes in motor severity based on Movement Disorder Society-Unified Parkinson's Disease Rating Scale motor sub-score (MDS-UPDRS part III, with higher numbers indicating more severe disease). During the follow-up period, the dose of anti-parkinsonism could be added if both the patients and doctors thought the clinical condition deteriorated. Changes in PD medication as measured by levodopa-equivalent dose (LED) will be recorded at each visit. The secondary endpoints measured include MDS-UPDRS total scores, Part I and Part II sub-scores, the timing and dose of added anti-parkinsonism medication during the treatment period, the changes of 18F-DOPA PET uptake and MMSE scores, and global impression scale (GCI) of patients and investigators at the end of the study. Expected results: We hypothesize that lovastatin would slow down both motor and cognitive symptoms deterioration and dopaminergic neuronal degeneration in patients with early stage PD. Importance of the study: Our study will provide Class II evidence that intensive lipid lowering with lovastatin 80 mg/day decrease the disease progression in patients with early stage PD.
Can tDCS Enhance Efficacy of Rehabilitative Intervention for Freezing of Gait in Parkinson's Disease?...
Parkinson DiseaseFreezing of gait in Parkinson's disease (PD) is a major cause of disability and falls and responds often incompletely to conventional therapy. The pathogenesis remains largely unknown and therapeutic alternatives are needed. Rehabilitative interventions that consist of learning cognitive strategies with sensory cueing to prevent and to overcome FOG represent the most efficacious intervention, but difficulties in learning and execution of these cognitive strategies are the main cause of failure. Transcranial direct current stimulation (tDCS) enhances motor task learning and execution in patients with PD and might enhance the efficacy of rehabilitative interventions. This study intends to address the following question whether tDCS can enhance the efficacy of rehabilitative interventions in the treatment of freezing of gait in Parkinson's disease?
Evaluation of the Nonmotor Symptomatology of Parkinsonian Patients Treated With Two Strategies Related...
Parkinson DiseaseThere is currently no consensus on the adequate concomitant treatment to apomorphine pump in Parkinson's disease (PD). In practice, some centers withdraw all dopaminergic agonists when initiating apomorphine pump therapy, whereas others combine the two. To date, there has been no study led to determine the best strategy for efficiently treating motor and nonmotor symptoms, as well as improving patients' quality of life (QoL). This preliminary study, entitled AGAPO, aims at identifying significant differences in patients' evolution (nonmotor symptoms and quality of life), over a course of 6 months, depending on the two strategies adopted in French centers (apomorphine pump with or without dopaminergic agonists), through the Non Motor Symptoms Scale (NMSS, Chaudhuri et al, 2017).
Pharmacist-led Perioperative Medicines Optimisation
Parkinson DiseasePatients attend pre-assessment clinics (POAC) who require an elective operation and who are having a general anaesthetic. At POAC patients are asked about their health, and past medical conditions to assess their fitness for anaesthetic, a list of medicines taken is documented. Patients can then be given a date for surgery. During their stay in hospital patients will see a pharmacist who confirms what medicines are being taken, and ensures those medicines are prescribed and available during the patients stay. This study is aimed at improving the care of patients who are admitted for elective surgery. The study will review two different interventions made prior to a patient's admission for surgery. One will look at a group of patients taking a high risk medicine and the other a group of patients with a high risk disease. The high risk medicine chosen is warfarin, and the high risk disease is Parkinson's disease. It is known that inappropriate or lack of medicines management in these groups can result in delayed surgery, poorer surgical outcomes and can affect a patient's recovery after surgery. Due to patient numbers and the variability between patients being too great, and a lack of research in this area a controlled trial cannot be performed. This complex intervention will review the interventions made, to understand how and why the interventions change care and what it is specifically within the interventions that are exerting a positive effect to improve care. All elective surgical patients who attend POAC at St James' University Hospital who are either, taking warfarin or who have Parkinson's disease will be seen by a pharmacist. An accurate drug history will be taken and if changes are required to medications these will be resolved at the POAC appointment. Patients will be provided with an individualised perioperative medication plan.
Motor Learning in Parkinson's Disease: Underlying Effective Connectivity and Influential Factors...
Parkinson DiseaseParkinson's disease (PD) is characterized by severe motor symptoms that can only be partially alleviated by medication. It was shown previously that rehabilitation is an important therapeutic supplement for micrographia in early disease. However, what is unknown is how motor learning impacts on the underlying neural networks in patients with different disease progression and how this interacts with dopaminergic medication. Furthermore, difficulties with upper limb motor control has a severe impact on the daily lives of PD patients since fine motor skills become increasingly important for the use of smartphones and tablets. Therefore, the current project will include a newly developed Swipe-Slide Pattern test, resembling the pattern codes used to unlock smartphones and tablets. This task will be used to determine learning-induced neuroplasticity of cortico-striatal effective connectivity across disease stages in PD. Using a combination of behavioral assessment and functional magnetic resonance imaging, the investigators aim to contribute to the understanding of upper limb motor learning in patients with PD for the development of individualized rehabilitation programs.
The Effect of Hericium Erinaceus Mycelium in Non-motor Symptoms of Parkinson's Disease
Parkinson DiseaseParkinson disease (PD) is considered a multisystemic neurodegenerative disorder, together with the classic motor disability, and a number of non-motor symptoms (NMS).NMS have a significant negative relation with patients' quality of life. In general, both medicinal and nonmedicinal therapies are often advised for PD patients with NMS, but robust evidences for underpinning the clinical effects are limited. Recently, the search for small preventative neurotrophic compounds that are responsible for the maintenance, survival of neurons has attracted much attention. Erinacine A, which is extracted from Hericium erinaceus is the one showed prominent beneficial effects in the central nervous system. It can increase NGF and catecholamine content in the locus coeruleus and hippocampus of rats. This markedly increases neuronal survival in different brain areas and substantially improve behavioral outcomes in various animal models. In a MPTP-induced Parkinsonism model, treatment with Hericium erinaceus mycelium reduced the loss of dopaminergic cell, eliminated neuronal apoptosis and reversed MPTP-associated motor deficits. Thus, this project intends to hold a randomized, controlled trial to assess the effect of Hericium erinaceus mycelium, which is enriched of Erinacine A, in NMS of PD. This project will enroll 80 patients with PD. Subjects will be randomly allocated into study or placebo group. Subjects will take Hericium erinaceus mycelium for 2 years (one capsule per meal per day) and their treatments for PD will not be altered.

Parkinson DiseaseThe researchers wish to determine what are patients/care partners priorities in terms of care delivery based at home/community and define the envisioning care delivery model that support both social care and medical care from the perspective of people living with Parkinson.
Stress Management and Resiliency Training Program for Parkinson's Disease
Parkinson DiseaseSMART-PD is an 8-session program designed to decrease the physiological, emotional, cognitive and behavioral effects of stress in participants with Parkinson's disease and their caregivers by teaching cognitive-behavioral techniques and relaxation skills to help participants learn to elicit the relaxation response, alter cognitive appraisals, improve healthy lifestyle behaviors and access social support. The SMART program has been shown to be effective for reducing mental health symptoms such as depression and anxiety as well as physical symptoms such as pain and in promoting positive health behaviors.
Brain Tissue Imprint
Parkinson DiseaseNeurologic DisorderThis exploratory study aims to validate the collection and analysis of brain tissue imprints during the DBS by using a CE marked Medical Device in patients presenting one of the following five disorders: Parkinson's disease (PD), essential tremor (ET), dystonia (DYS), Obsessive compulsive disorder (OCD) and Tourette Syndrome (TS). The Brain Tissue Imprint project is focused on the DBS surgical procedure, which constitutes an appropriate method to collect brain tissue imprints by taking advantage of the direct and transitory contact at the extremity of the dilator with adjacent brain tissue. Indeed, during this step, micro-fragments of brain material spontaneously adhere to the dilator tip. It is this imprinting process that allows to collect what is defined as "brain tissue imprints. This approach is part of the standard surgical procedure of the SCP without major change or complications.
