In Nuclear Medicine, the examinations are long (20-60 minutes) and the patients must remain immobile, sometimes fasting. The anxiety of the latter can lead to poor quality examinations and sometimes, although already injected with radioactive drugs, the patients refuse the examination. In imaging, the use of hypnosis (prior to the MRI examination or with the patient during a scintigraphic examination) is frequent due to the conformation of MRI or scintigraphic machines, particularly for claustrophobic patients (2-2.5% of cases). Medical electroradiology manipulators (MERM) have been trained to practice Ericksonian hypnosis whose effectiveness in combating anxiety is no longer in question. Scientific studies by Faymonville et al, 2006 and Rainville et al, 2002, have shown the effectiveness of this method in managing anxiety using the simplified STAI-6 scale before and after hypnosis. The dosimetric study of the MERM position would then be greatly modified in favor of a decrease in exposure targeted by the June 4, 2018 decree on personnel safety. The impact of whether or not the MERM is physically present near the patient would also be studied. If minimal, this will resolve the current contradiction between the quality of patient care delivered and the radiation protection imposed in nuclear medicine. The investigators propose here a pilot study evaluating remote-delivered Ericksonian hypnosis versus conventionally-delivered Ericksonian hypnosis, which will allow for the sizing of a subsequent multicenter randomized non-inferiority controlled trial. Indeed, there is currently no data available on the non-inferiority margin of this technique.
Patients with Parkinson's disease (PD) are commonly treated with a combination of levodopa and a decarboxylase inhibitor (DCI). However, many PD patients experience motor fluctuations (OFF episodes), even with their regular levodopa/DCI treatment. This unmet medical need was addressed by the approval of INBRIJA®, an orally inhaled product, for producing therapeutic relief during the OFF episodes. INBRIJA® is a capsule-based inhaler system and in order to administer the full dose of levodopa, the patients need to inhale the contents of two capsules. In order to administer the full dose of levodopa, patients need to inhale the contents of two capsules. Since the INBRIJA® device is a standalone and reusable unit, the patients have to load the capsule prior to inhalation several times a day during the OFF episodes (except early-morning OFF) to get relief. Also, the INBRIJA® device is repeatedly used by PD patients and therefore needs to be properly cleaned to avoid contamination. PureIMS is developing a more user-friendly alternative called Levodopa Cyclops™, a pre-filled drug-device combination of levodopa inhalation powder for use with the Cyclops™ dry powder inhaler. Due to the nature of the Cyclops™, it offers PD patients greater ease and convenience in use. Moreover, the device's moderate to high resistance to airflow and minimal use of excipients suggests minimal cough episodes during oral inhalation. The current study is planned in order to determine the dose at which comparative bioavailability of Levodopa Cyclops™ will be reached compared to INBRIJA®.
Resting tremors associated with Parkinson's disease (PD) remains difficult to quantify and track during disease progression. This study propose to explore the rhythmicity of distal muscle contractions in the upper limb to characterize resting tremor and discriminate it from cerebellar tremor (CT) based on the frequency spectrum of the EMG signal.
Background: Falls are common in elderly individuals and those with neurological conditions like Parkinson's disease. Parkinson's disease causes postural instability and mobility issues that lead to falls and reduced quality of life. The fear of falling (FoF), a natural response to unstable balance, can exacerbate postural control problems. However, evaluating FoF relies primarily on subjective self-reports due to a lack of objective assessment methods. Objectives: This mixed-methods feasibility study aims to develop an objective method for assessing fear of falling during motion and walking using virtual reality. This protocol examines a range of FoF-related responses, including cognitive, neuromuscular, and postural stability factors. Methods: Individuals without and with Parkinson's disease will complete questionnaires, movement tasks, and walking assessments in real and virtual environments where FoF can be elicited using virtual reality (VR) technology. Data from center-of-pressure measurements, electromyography, heart rate monitoring, motion capture, and usability metrics will evaluate the method's acceptability and safety. Semi-structured interviews will gather participants' and researchers' experiences of the protocol. Discussion: This method may allow accurate assessment of how FoF impacts movement by measuring cognitive, neuromuscular, and postural responses during gait and motion. Virtual environments reproduce real-life scenarios that trigger FoF. Rigorously assessing FoF with this approach could demonstrate its ability to quantify the effects of FoF on movement. Conclusions: This protocol aims to improve FoF assessment by evaluating multiple responses during movement in virtual environments. It addresses current measures' limitations. A feasibility study will identify areas for improvement specific to Parkinson's disease. Successful validation could transform how FoF is evaluated and managed.
Parkinson's Disease (PD), first described by James Parkinson in 1817, is a progressive movement disorder that develops mainly as a result of the destruction of nigrostriatal dopaminergic neurons. The aim of our study is to determine the effect of cognitive functions on upper extremity functionality in individuals with Parkinson's Disease.
The most common genetic risk factor for Parkinson's Disease is a heterozygous mutation of the GBA1 gene, encoding the lysosomal enzyme glucocerebrosidase (GCase). Reduced GCase activity is associated with aggregation of the protein alpha synucleine (aSyn) in the central nervous system, which is related to the pathological cause of PD. Ambroxol is a mucolytic expectorant that appears to facilitate the refolding of the misfolded GBA protein thats acts as a chaperone for GCase. This randomized placebo-controlled trial aims to investigate the disease-modifying properties of ambroxol in PD patients with a GBA1-mutation. Patients will undergo motor and cognitive tests, as well as imaging and blood tests.
The goal of this clinical trial study is to learn about the effect of aquatic exercise in parkinson's patients. The main questions it aims to answer are: - What is the effect of exercise in water on balance in parkinson's patients? - What is the effect of exercise in water on muscle strength in parkinson's patients? - What is the effect of exercise in water on flexibility in parkinson's patients? Parkinson's patients in this study will do some functional tests. One group of them will do exercises in water 3 times weekly for 8 weeks.
Hereditary Parkinson and dystonia syndromes are rare, as are people who carry the predisposition for Parkinson or dystonia but do not have symptoms. It is particularly important to study these people because they are a good model for understanding the development of common non-hereditary Parkinson's and dystonia. To do this, the investigators want to look at how the brain works and how different areas of the brain communicate with each other. The investigators want to identify differences in brain regions connecting perception and action between mutation carriers that develop clinical symptoms and those who stay healthy in different subgroups of inherited Parkinson-dystonia syndromes. Mutation carriers with and without symptoms of three different inherited Parkinson-dystonia syndromes will be investigated at their homes with the help of a mobile examination unit. To detect even subtle signs, which the mutation carriers might not even be aware of, the investigators will use a detailed video-based and -documented movement examination and a non-invasive magnetic stimulation technique that investigates how a sensory, i.e., electrical stimulus can influence the motor response in a hand muscle. Our study will allow the investigators, on the one hand, to define specific markers that protect some mutation carriers from having clinical symptoms and, on the other hand, to identify neurophysiological characteristics that all mutation carriers share whether or not they have clinical symptoms. These are important information for a better understanding of the basis of these disorders and for the development of new treatment strategies, which can also be transferred to genetically-undefined Parkinson's and dystonia syndromes. Through this study, large groups of mutation carriers that have received an in-depth clinical and neurophysiological examination and can be investigated longitudinally in future studies will be build up.
123I-FP-CIT SPECT (DaTSCAN®) allows to detect presynaptic dopamine neuronal denervation. It is recommended to differentiate neurodegenerative parkinsonism from secondary parkinsonian syndromes or from essential tremor, and to distinguish patients with suspected dementia with Lewy bodies and those with other subtypes of dementia. The aim of this retrospective study was to evaluate the relevance of 123I-FP-CIT SPECT prescriptions, the profile of prescribers and the evolution of the prescription rate over a ten-year period.
