The collaborative research involving researchers from Italy, Sweden, France, Denmark, Croatia and Luxembourg is funded with 1.75 Mio EUR over three years by the European ERA PerMed scheme of the Horizon Europe initiative of the EU (Grant Agreement Number: 779282 \u2013 Project Grant Number: INTER\/PerMed22\/17045084), which aims to strengthen European collaboration and competitiveness in the field of personalised medicine.<\/p>\n\n\n<figure class=\"wp-block-dev4-reusable-blocks-image  object-fit--contain\">\n    \n<img decoding=\"async\" class=\"wp-block-image unilux-custom-image-block\"\n                alt=\"Deepen iRBD launch meeting\"\n            src=\"https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/22\/2023\/04\/deepen-irbd-launch-meeting.png\"\n                srcset=\"https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/22\/2023\/04\/deepen-irbd-launch-meeting-300x200.png 300w, https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/22\/2023\/04\/deepen-irbd-launch-meeting-1024x684.png 1024w, https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/22\/2023\/04\/deepen-irbd-launch-meeting-768x513.png 768w, https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/22\/2023\/04\/deepen-irbd-launch-meeting-1536x1025.png 1536w, https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/22\/2023\/04\/deepen-irbd-launch-meeting.png 2000w\"\n                style=\"object-position: 50.00% 50.00%; font-family: &quot;object-fit: contain; object-position: 50.00% 50.00%;&quot;; aspect-ratio: 4\/3; object-fit: contain; width: 100%;\"\n        loading=\"lazy\"\n\/>    <\/figure>\n\n\n<h4 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"irbd-as-a-common-indicator-for-different-forms-of-parkinsonism\"\n    >\niRBD as a common indicator for different forms of parkinsonism<\/h4>\n\n\n\n<p>Idiopathic REM sleep behaviour disorder (iRBD) is a specific sleep disorder in which people act out their dream through uncontrolled movement and actions. It has been linked to a high risk of conversion to Parkinson\u2019s disease, multiple system atrophy, or dementia with Lewy bodies. These neurodegenerative diseases are also referred to as synucleinopathies, as they share similarities at the cellular level. Here the protein alpha-synuclein aggregates inside the nerve cell, leading to functional disturbances and premature ageing and death of the cell. While early clinical features of the diseases, such as mood changes, sleep disturbances and mild cognitive impairment, are similar, the later stages present much differently, with significant therapeutic and prognostic consequences for patients.<\/p>\n\n\n\n<p>\u201cOnce curative treatments become available, it will be important to accurately identify patients close to developing the different forms of parkinsonism to be able to take a targeted treatment approach\u201d, explains Prof. Kr\u00fcger, principal investigator from Luxembourg in the DEEPEN-iRBD project.<\/p>\n\n\n\n<p>While Parkinson\u2019s disease is the closest to a pure motor syndrome, with only mild cognitive impairment, dementia with Lewy bodies shows much more severe cognitive impairment, which can lead to hallucinations. Patients with multiple system atrophy show intermediate cognitive impairment relative to Parkinson\u2019s disease and dementia with Lewy bodies but often present particularly prominent autonomic symptoms, such as urinary dysfunction and sudden drops in blood pressure upon standing. The difference in clinical symptoms between the three diseases is mainly due to different types of cells and brain structures being affected by the aggregation of the alpha-synuclein protein.<\/p>\n\n\n\n<h4 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"luxembourgish-expertise-and-data-to-further-improve-early-diagnosis-and-treatment\"\n    >\nLuxembourgish expertise and data to further improve early diagnosis and treatment<\/h4>\n\n\n\n<p>The DEEPEN-iRBD project aims to identify specific profiles beyond iRBD that allow the diagnosis and distinction between the three synucleopathies early on, even in the prodromal phase, before any cognitive or motor symptoms arise. The study will utilise existing and newly acquired data, including physiological signal recordings, molecular markers from body fluids, skin biopsy, and brain cells stemming from reprogrammed patient skin cells. The University of Luxembourg is highly involved in data management, protection, and dissemination, as well as providing data and samples from patients previously diagnosed with iRBD through the nationwide \u201cREM-Sleep Behaviour Study\u201d and the participants of the Luxembourg Parkinson Study. Both studies are being coordinated by the National Centre of Excellence in Research on Parkinson&rsquo;s disease (NCER-PD), an initiative of the Luxembourg National Research Fund (FNR\/NCER13\/BM\/11264123) supporting the joint effort of the partner institutions, Luxembourg Centre for Systems Biomedicine, Luxembourg Institute of Health, Centre Hospitalier de Luxembourg, and Laboratoire National de Sant\u00e9, in successfully paving the way for precision medicine concepts for Parkinson\u2019s disease.<\/p>\n\n\n\n<p>Our study can potentially improve early risk identification, diagnosis, treatment and prognosis of patients with iRBD, prone to convert to Parkinson\u2019s disease, multiple system atrophy or dementia with Lewy bodies. The ultimate goal is to be able to implement personalised medicine strategies, which are tailored to each patient and their unique characteristics, instead of treating every person living with a form of parkinsonism the same. This approach can help alleviate symptoms and optimise prevention, diagnosis, and treatment strategies.<\/p>\n\n\n\n<p>\u201cThis new study will help us develop guidelines on when and how we communicate such early screening results to people with a high risk of developing different forms of parkinsonism in the future.\u201d<\/p>\n\n\n\n<h4 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"about-ncer-pd\"\n    >\nAbout NCER-PD<\/h4>\n\n\n\n<p>The <a href=\"https:\/\/www.parkinson.lu\" target=\"_blank\" title=\"\" rel=\"noopener\">National Centre of Excellence in Research on Parkinson&rsquo;s Disease (NCER-PD)<\/a> aims to improve the diagnosis and stratification of Parkinson&rsquo;s disease by combining detailed clinical and molecular data of patients to develop novel disease biomarker signatures.

The first phase of the study involved an online survey of over 20,000 Luxembourg residents aged 55-75 to gather information on sleep quality and symptoms of RBD. Participants who show potential symptoms of RBD were then contacted for further assessments, including an at-home smell test and a second questionnaire. The study aims to better understand the early phases of neurodegenerative diseases and determine strategies for preventing them. The large number of participants and the use of non-invasive assessments make this study a valuable contribution to sleep and Parkinson&rsquo;s disease research.<\/p>\n\n\n\n<h4 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"about-erapermed\"\n    >\nAbout EraPerMed<\/h4>\n\n\n\n<p><a href=\"https:\/\/erapermed.isciii.es\" target=\"_blank\" title=\"\" rel=\"noopener\">ERA PerMed<\/a><a href=\"https:\/\/erapermed.isciii.es\/wp-content\/uploads\/2023\/02\/Newsletter-January-23_final1.pdf\" target=\"_blank\" title=\"\" rel=\"noopener\">The DEEPEN-iRBD study is coordinated by Graziella Cappelletti from the University of Milan.
