Filter by:This study aims at the constitution of a large cohort of adult subjects without Rapid eye movement (REM) sleep behavior disorder (RBD), among whom subjects with isolated REM sleep without atonia (RSWA) will be identified; their long-term follow-up, compared to subjects without RSWA, will be useful in the next years to understand if this condition represents a risk factor for the future development of RBD, a condition in which the development of a neurodegenerative disorder (especially synucleinopathy) is highly probable. This will allow to obtain a wide time window for the establishment of prevention and neuroprotection in these subjects, with the goal to avoid or delay the development of the RBD>synucleinopathy sequence. All Units will recruit a large number of subjects without RBD undergoing a polysomnography (PSG) recording, with a shared protocol, and the data collected will be stored on a web-based common database. Subjects showing RSWA in their PSG will be identified and used as a prospective study group, which will start at the end of the recruitment of this project.
To assess the effects of a daily single oral dose of 20 mg tasimelteon compared to baseline on events of dream enactment on patients with REM Behavior Disorder, as measured by a daily log. To assess the effects of 20 mg tasimelteon compared to baseline on insomnia= symptoms, as measured by validated questionnaires (Insomnia Severity Index [ISI], Pittsburgh Sleep Quality Inventory [PSQI], Epworth Sleepiness Scale [ESS], Clinical Global Impression of Change Scale (CGI-C), Patient Global Impression of Change Scale (PGI-C)) as well as rest/activity pattern from actigraphy. - To assess the effects of 20 mg tasimelteon on patients who have a reduced or aberrant melatonin secretion compared to normal secretion by measuring salivary DLMO at baseline and correlating with the degree of change in RBD symptoms by end of the study. - To assess for any role a patient's unique genome may play in their response to tasimelteon; obtained via whole genome sequencing. - To assess the safety and tolerability of a daily single oral dose of 20 mg tasimelteon.
The genetic complexity and heterogeneity of the sporadic forms of Parkinson's disease (PD) are posing a formidable challenge to disentangle their direct molecular causes. To advance this research, we plan to coordinate our local biorepositories of PD biological specimens creating a standardized and integrated national resource. In this framework, we plan to collect more samples from additional sporadic PD cases and to extend the sampling to patients with REM sleep behavior disease. We plan a large campaign of whole genome sequencing including about 200 patients to identify rare genomic variants plausibly associated with these diseases. In addition, we will standardize the generation and quality control of iPSC lines to make available to the scientific community. Finally, we will combine iPSC technology and gene editing to functionally assess the relative impact of rare variants in coding regions inherited together as a polygenic trait previously identified in selected sporadic PD cases
To investigate whether a year of rasagiline may reduce the progression from idiopathic REM sleep behavior disorder (RBD) to Parkinson's disease (PD).
About 60% of Parkinson's Disease (PD) patients have REM sleep Behavior Disorder (RBD), a parasomnia characterized by partial or complete loss of REM sleep muscle atonia and dream-enacting behaviors, usually associated to vivid dreams. The REM Sleep without atonia is the polysomnographic hallmark of RBD, and its quantification is necessary for the diagnosis. RBD in PD is believed to be a marker of a more widespread degenerative process and a marker of malignant phenotype. Therefore, PD patients with RBD (PD-RBD) are more severely impaired in both motor and non-motor domains, compared to those without RBD, with an increased risk of dementia. However, little is know about the relationship between the evolution of RBD, clinic and video-polysomnographic, and the progression of PD. Besides, an improvement of RBD symptoms is anecdotally reported in PD patients over time. Longitudinal evaluation of RBD in PD, assessed by questionnaires, led to controversial results, but so far, no longitudinal vPSG study has been performed in PD-RBD population. Thus, the main objective of this study is to longitudinally evaluate clinical and video-polysomnographic features of RBD, including measure of REM Sleep without atonia, in patients with PD-RBD, after three years from the diagnosis of RBD, in order to ascertain whether RBD features remain stable over time. The possible remission of RBD with the progression of PD would question indeed its reliability as prognostic bio-marker.
The purpose of this study is to determine whether melatonin prolonged-release (PR) and clonazepam are effective and safe in the treatment of rapid eye movement behavior disorder (RBD) of patients with Parkinson's disease (PD).
