Filter by:People with Parkinson's disease (PD) commonly experience a range of both motor (e.g., bradykinesia, rigidity, tremor, and postural instability) and non-motor (e.g., fatigue, psychiatric and behavioural disturbances, autonomic dysfunction, cognitive impairment, sleep dysfunction and olfactory loss) features. Currently, it is challenging to alleviate these symptoms with first-line treatment, the medications such as levodopa. The CUE1 is a non-invasive device, which is approved for sale in the UK market as a Class I low risk device. It is worn on the sternum or other part of the body such as the forearm and attaches to the skin via an adhesive patch which has been dermatologically tested and approved. The CUE1 delivers pulsing cueing and vibrotactile stimulation to help improve symptoms in people with PD and it has shown to be effective in doing so in previous small case studies. This 9-week feasibility study aims to investigate the feasibility, safety, tolerability and effect of using the CUE1 as an intervention to improve motor and non-motor symptoms in people with PD and related movement disorders. People with clinical diagnosis of idiopathic PD and related disorders including those with progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, and vascular Parkinsonism as well as atypical dystonias and tremor disorders aged over 18 years old who have the capacity to provide a written consent form to take part in the study, will receive as intervention to wear the CUE1 device at home, on daily basis while carrying out their activities of daily living. Participants will also have to attend four face-to-face appointments of approximately half a day, at weeks -0, -3, -6 and -9 of the study to discuss how they are getting on with using the CUE1 and complete questionnaires on their symptoms, walking, balance, and movement tests as well as a participant's clinical diary.
The purpose of this study is to learn more about the effectiveness of palliative care training for community physicians and telemedicine support services for patients and carepartners with Parkinson's disease and Lewy Body Dementia (LBD) or related conditions and their care partners. Palliative care is a treatment approach focused on improving quality of life by relieving suffering in the areas of physical symptoms such as pain, psychiatric symptoms such as depression, psychosocial issues and spiritual needs. Telemedicine is the use of technology that allows participants to interact with a health care provider without being physically near the provider.
Diagnosing Parkinson's disease (PD) depends on the clinical history of the patient and the patient's response to specific treatments such as levodopa. Unfortunately, a definitive diagnosis of PD is still limited to post-mortem evaluation of brain tissues. Furthermore, diagnosis of idiopathic PD is even more challenging because symptoms of PD overlap with symptoms of other conditions such as essential tremor (ET) or Parkinsonian syndromes (PSs) such as progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal degeneration (CBD), or vascular Parkinsonism (VaP). Based on the principle that PD and PSs affect brain areas involved in eye movement control, this trial will utilize a platform that records complex eye movements and use a proprietary algorithm to characterize PSs. Preliminary data demonstrate that by monitoring oculomotor alterations, the process can assign PD-specific oculomotor patterns, which have the potential to serve as a diagnostic tool for PD. This study will evaluate capabilities of the process and its ability to differentiate PD from other PSs with statistical significance. The specific aims of this proposal are: To optimize the detection and analysis algorithms, and then to evaluate the process against neurological diagnoses of PD patients in a clinical study.
Vascular parkinsonism (VP) is defined as the presence of parkinsonian syndrome, evidence of cerebrovascular disease by brain imaging and an established relationship between the two disorders. However, the diagnosis of VP is problematic. This study aims to distinguish VP from Parkinson's disease (PD) in multiple aspects including clinical features as motor ,non motor symptoms ,response to treatment ,cognitive assessments by using multiple scales, neuro-radiological features of magnetic resonance imaging (MRI) and transcranial color-coded duplex (TCCD) findings. This differentiation will have therapeutic and prognostic implications .
This home-based study is a randomized (1:1) placebo-controlled trial of a single infusion of zoledronic acid-5 mg (ZA) for the prevention of fractures in men and women aged 60 years and older with Parkinson's disease and parkinsonism with at least 2 years of follow-up. A total of 3500 participants will be enrolled and randomized in the United States. Participants, follow-up outcome assessors, and study investigators will be blinded to assigned study treatment. This trial is funded by the National Institute of Aging.
Vascular parkinsonism (VP), parkinsonism resulting from ischemic cerebrovascular disease, was suggested in 1929. The main features are wide-based gait, postural instability, and falls, which make patients with VP frustrated. Currently, the treatment is challenging. Transcranial magnetic stiumation is a noninvasive procedure using electromagnetic induction to stimulate brain, and repetitive transcranial magnetic stiumation (rTMS) can selectively change brain activity to enhance desired effects. The aim of this study is to explore the therapeutic effect of rTMS for the VP.
Parkinsonian syndrome is clinically characterized by the presence of resting tremor, rigidity, bradykinesia and postural instability. Parkinsonian disorders include Parkinson's disease (PD), progressive supranuclear palsy (PSP), corticobasal dementia (CBD), multiple system atrophy (MSA) and vascular parkinsonism (VP). Each of these diseases has a singular physiopathological origin, course and prognosis. Numerous imaging studies consequently aimed at finding markers to early make the distinction between the different types of parkinsonism, in order to identify patients who could benefit from dopaminergic agonist therapy. Excessive iron deposition in the subcortical and brainstem nuclei has been described in numerous neurodegenerative disorders including Parkinson's disease. Increased iron levels are more frequent in area that are rich in dopaminergic neurons and have been implicated in the development of movement disorders, the distribution of areas with increased iron deposition however varying according to parkinsonism types. Iron deposition quantification could thus potentially help in differentiating parkinsonism types and could improve therapy guidance. Quantitative susceptibility mapping (QSM) locally estimates the magnetic susceptibility of brain tissues based on gradient-echo signal phase. The local susceptibility being sensitive to the presence of paramagnetic susbtances, QSM allows the non-invasive evaluation of iron distribution and quantification in the brain with high image quality (Liu et al., 2013). However, since iron deposition followed an exponential curve during normal aging in most of the basal ganglia the potential of QSM to distinguish between healthy and parkinsonian subjects in elderly remains unclear. The aim of this study was thus to determine susceptibility values in the basal ganglia of elderly patients with parkinsonian syndromes, to compare these values to healthy aged-matched controls and between parkinsonian syndrome types. Secondly, investigators aimed to evaluate microstructural changes in the basal ganglia using diffusion tensor imaging (DTI) in the same population and to determine whether susceptibility and DTI parameter changes are correlated. Finally investigators sought to assess the relation between susceptibility/DTI parameter values in the basal ganglia and behavioral measures of motor and cognitive abilities.
Forty patients with clinically diagnosed VP and 20 healthy subjects will be enrolled in the study. Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria and each subject will have 3 visits in the study, as one screening visit, one imaging visit, and one safety evaluation visit.
The purpose of the study is to determine the sensitivity and specificity of transcranial duplex scanning (TCD) and single photon emission computer tomography (SPECT) in patients suspected of having Idiopathic Parkinson Disease (PD) or Atypical Parkinson Syndromes (APS) with as golden standard the clinical diagnosis after 2-year follow-up.
