Driving Performance of People With Parkinson's Using Autonomous In-Vehicle Technologies
Parkinson DiseaseFor drivers with Parkinson's Disease (PD), autonomous in-vehicle technologies may help mitigate functional deficits, improve driving performance, decrease driving errors and enhance their ability to stay on the road. Using a pretest/posttest design the investigators will quantify the use of In-vehicle Information Systems (IVIS) and Advanced Driver Assistance Systems (ADAS) during driving to illustrate how IVIS and ADAS may affect driving, and provide recommendations to drivers with PD, the clinical community and industry.
Parkinson's Disease: Risk Assessment of Persistent Delirium and Its Management
Parkinson DiseaseDelirium in Old AgeBackground: delirium describes the change in people's behaviour and thinking when they are unwell. People with delirium may appear confused, have difficulty with organisation and can be different to their usual personality. Older people with Parkinson's are particularly susceptible to persistent delirium, which can last over 14 days. They are more likely to need increased community support and they have a greater risk of death and dementia. However, there is limited research for people with Parkinson's on how to effectively manage persistent delirium and how to identify those at risk of persistent delirium. Community support may not sufficiently support the care needs of people with Parkinson's, and this is expected to be more detrimental for people also affected by persistent delirium Study Design: retrospective case note review with qualitative interviews. Study participants: older people (≥65 years old) with Parkinson's disease, previously affected by either persistent delirium or another form of delirium (e.g. hyperactive, hypoactive, mixed). 207 participants with Parkinson's for quantitative data collection. The qualitative study will include up to 10 participants with Parkinson's from the quantitative part of this study. An additional maximum of 10 more carers for people with Parkinson's may also be interviewed. Research Aims: To develop and estimate the assessment tool's sensitivity and specificity to predict persistent delirium in older people with Parkinson's in the outpatient setting. Persistent delirium in this study will be initially defined as a delirium lasting ≥14 days. An associated secondary objective will be to develop a scoring system that allocates an increasing number of points to risk factors that have a stronger association for predicting delirium. To evaluate the management strategies used for persistent delirium. To determine what are the community care needs for people recovering from persistent delirium.

Neurofeedback Using Implanted Deep Brain Stimulation Electrodes
Parkinson DiseaseEpilepsy1 moreDeep brain stimulation (DBS) has become a gold-standard symptomatic treatment option for Parkinson's disease (PD) and is also explored for a variety of other neurological disorders. The implantation of electrodes into deep brain areas has not only enabled the application of electrical stimuli, but has also provided researchers and clinicians with an unprecedented window to investigate aberrant neuronal activity right at the core of pathological brain circuits. Local field potentials (LFP) have already been readily investigated through externalised DBS electrode wires prior to internalisation and connection to an implantable neurostimulator. In the case of PD, motor symptoms have been evidenced to correlate with exaggerated beta oscillatory activity (13-35 Hz) in the LFP recorded from the subthalamic nucleus (STN). Firstly, beta activity recorded in the STN at rest in patients withdrawn from their medication has been correlated with the Unified Parkinson's Disease Rating Scale (UPDRS) across patients. Secondly, a reduction of signal power in the beta-band was correlated with clinical improvements of motor symptoms. Thirdly, the two main therapeutic strategies, the administration of L-Dopa, and high-frequency DBS both lead to a suppression of beta-synchronicity in the STN. Furthermore, beta-oscillations show fast and movement-dependent modulation over time and can serve as a biomarker and feedback signal to control the delivery of DBS. The investigators recently implemented deep brain electrical neurofeedback to provide real-time visual neurofeedback of pathological STN oscillations through externalised DBS electrodes and showed that PD patients were able to volitionally control and reduce subthalamic activity within a single 1 hour session. Moreover, neurofeedback-learnt strategies accelerated movements and could be retained in the short- and mid-term. Only recently, a newly developed neurostimulator, the Percept™ PC (Medtronic Neurological Division, Minneapolis, MN, USA), has been clinically approved, which can not only apply electrical impulses, but also enable the measurement and transmission of brain activity. This neurostimulator is now the first choice for implantations at the University Hospital Zurich and is used for a variety of neurological disorders. The investigators' goal is to investigate whether neurofeedback through a fully implanted deep brain stimulation device is possible and can lead to a better control of pathological oscillations as well as symptom mitigation. Having shown that endogenous control over deep brain oscillations is possible, the investigators will also test this novel therapeutic approach for pathologies other than PD that are also treated with DBS. Neurofeedback using implanted DBS electrodes will have the advantage of enabling longer and multiple-day training sessions, which the investigators hypothesise to have a larger impact on control over pathological deep brain oscillations and neurological symptoms, as such a fully implanted neurofeedback system no longer requires the externalisation of DBS wires and is as such no longer limited to the first two days after electrode implantation. All in all, the investigators will not exceed a total streaming time of 7 hours per patients (7 d of battery time), which the investigators deem justifiable with respect to a battery life of > 5 years. This proposed research is highly significant as it will help our understanding of various neurological diseases that are highly prevalent in society (PD being, for instance, the second most common neurodegenerative disorder after Alzheimer's disease) and might culminate in novel, endogenous treatment strategies. The overall risk for patients is minimal to non-existent, as stimulation parameters are unaffected and the intended changes in brain activity are self-induced while DBS stimulation is off.
The Personalized Parkinson Project de Novo Cohort
Parkinson DiseaseParkinsonian Disorders6 moreCurrently, the Movement Disorders Society (MDS)-UPDRS scale remains the gold standard to document the outcomes in clinical trials for Parkinson's disease (PD). The MDS-UPDRS is far from infallible, as it is based on subjective scoring (using a rather crude ordinal score), while execution of the tests depends on clinical experience. Not surprisingly, the scale is subject to both significant intra- and inter-rater variability that are sufficiently large to mask an underlying true difference between an effective intervention and placebo. Digital biomarkers may be able to overcome the limitations of the MDS-UPDRS, as they continuously collects real-time data, during the patient's day to day activities. In this study the investigators are interested in developing algorithms to track progression of bradykinesia, gait impairment, postural sway, tremor, physical activity, sleep quality, and autonomic dysfunction (the latter being derived from e.g. skin conductance and changes in heart rate variability).
Evaluation of Dopaminergic Denervation by DaTSCAN Brain Scintigraphy Using a New Multipurpose CZT...
Parkinson DiseaseDaTSCAN is an important tool in the diagnosis and clinical management of Parkinson's syndromes. New cadmium-zinc-telluride (CZT) systems allow time and/or dose reduction. This can be interesting in DaTSCAN acquisitions as those are long-lasting, often on difficult patients. This study will evaluate the diagnostic performances of a new 3D-ring CZT camera in DaTSCAN SPECT.
Validation of Bulbicam for Parkinson- and Ataxia-patients
Parkinson DiseaseAtaxiaAim is to investigate repeatability and stability of four Neurological-related Bulbicam tests in patients suffering Parkinson (PD),Ataxia (AT) and matched healthy control (HC). Study population The study consists of the patients suffering from PD or AT and HV of both genders above 18 years of age without any eye- or neurological disorder. Bulbicam will be used in the study and five tests will be performed The study will be performed as a controlled, open and non-randomized, stratified observational single center. The stratification factors will be pathology (PD&AT) and internal classifications. ed. The main variables will be the variables recorded at the four Bulbicam tests and the standard neuro-ophthalmological variables included for PD and AT Participants, who fulfil the inclusion criteria; do not meet any of the exclusion criteria and willing to give informed consent to participate will receive an appointment for starting the study. During the first day of the study, the included patients will undergo a neuro-ophthalmological examination by a neurologist. Additionally, Bulbicam examination will be performed twice with a rest period of one hour between each registration. The healthy controls will only undergo a standard examination and twice BulbiCam examination. The controls will only participate one day. The patients will participate two more days with two Bulbicam examinations per day. Sample size: Sixteen PD-patients ,16 AT-patients and 32 HCs will be included in the study.

Cue X as a Treatment for People With Parkinson's Disease
Parkinson DiseaseParkinson's disease is a progressive neurological condition which affects more than 145,000 people in the United Kingdom (UK) today. The main symptoms are tremor (uncontrolled shaking), slowness of movement and difficulty starting movements (termed 'freezing'). Daily exercise is recommended to help with these symptoms. Rehabilitation can help to maintain a person's balance, ability to walk and help to prevent falls. This can allow people living with Parkinson's to maintain their independence for longer. Rehabilitation is usually carried out at face-to-face appointments in outpatient departments in hospitals. STROLLL (www.strolll.co) is a company that have created a programme of activities called Cue X, to be used on augmented reality glasses. Augmented reality glasses merge computer generated images and sounds with the real world. Cue X has been created specifically to help people with Parkinson's. We are aiming to recruit 50 participants through referrals from specialist doctors, nurses and physiotherapists in Leeds Teaching Hospitals National Health Service (NHS) Trust. We will ask these health care professionals to give potential participants an information sheet outlining the project. A more detailed participant information sheet will be sent by post or email to those interested. There will be an initial hospital appointment where written consent will be asked for and an initial assessment completed. Participants will do a personalised, daily rehabilitation programme using Cue X on augmented reality glasses for 6 weeks at home (monitored remotely by a physiotherapist). A final assessment and review will be done in hospital. The purpose of this project is to see if people with Parkinson's can use the glasses and do exercises in their own homes. Benefits could include fewer trips to the hospital for appointments and a more engaging way of participating in rehabilitation. If successful, this could lead further research into this technology as a new way of delivering rehabilitation.
Rhythmic Auditory Stimulation on Upper-limb Movements in PD Patients
Acoustic StimulationParkinson Disease4 moreThe goal of this clinical trial is to examine effects of training involving rhythmic auditory stimulation (RAS) on upper-limb movements and functions in patients with Parkinson's disease (PD). Patients will be randomly divided into two groups: the RAS group and the no-RAS group. Patients will receive training with or without the aid of RAS based on their groups. The training task is to use the right hand to take beads from one bowl to another bowl. The box and block test and the Jebsen hand function test will be used before and after training (i.e., pretest and posttest respectively) to assess patients' upper-limb speed and function. Researchers will compare scores of the box and block test and the Jebsen hand function test between the two groups at pretest and posttest to determine effects of RAS.
