Neurogenic Encephalopathy

The GENESIS clinical study aims to map HLA genetic variation in the Greek population and evaluate possible correlations with selected underlying diseases. It is a multicenter, prospective, non-interventional clinical study targeting 12,000 subjects over an anticipated duration of 36 months, with the goal of creating a pilot HLA map for medical research and possible clinical applications. Each subject will complete one visit at a participating site and provide demographic information, including date of birth, gender, race, ancestry, height, and weight, as well as information about smoking or vaping, alcohol consumption, arterial blood pressure, diagnosed diseases, and current treatments. Recent clinical laboratory results from up to 12 months before sample collection may also be collected when available, including blood count, metabolic, liver enzyme, and biochemical parameters. Two buccal swabs will be collected from each subject for DNA extraction and HLA genotyping analysis. Selected DNA samples will also undergo low-pass whole genome sequencing to further investigate associations between the HLA region and autoimmune diseases. After the analysis is completed, an individualized ancestry report will be securely available to study subjects if they elect to access it.

Adults with intellectual disabilities often face challenges in social situations due to difficulties in processing social information, especially in recognizing facial emotions. This research evaluates a cognitive remediation program called Re9habilitus, designed to improve attentional and visuospatial functions to reduce behavioral disorders in adults with intellectual disabilities who do not have autism spectrum disorder. The study aims to validate whether this program can help address specific cognitive and behavioral issues in daily life for this population. Participants are randomly assigned to either the Re9habilitus cognitive remediation program, which focuses on improving attention and spatial perception related to social behavior, or to a control group engaging in manual activities and computer-based research tasks. The study compares these two approaches to assess their effects on behavioral disorders and cognitive functions. During the study, participants are assessed on changes in hyperactivity and non-compliance behaviors using the Aberrant Behavior Checklist scale over six months. Researchers also measure improvements in facial emotion recognition and attentional functions at the start, end, and six months after the intervention. The total participation time and safety monitoring details are aligned with the evaluation periods, ensuring thorough follow-up to observe lasting effects.

Researchers are investigating the effects of a multidomain lifestyle intervention to slow cognitive decline and dementia risk in elderly residents aged 60 to 80 in Zhejiang Province, China. The study builds on findings from Finland, where a similar approach combining physical activity, nutrition, cognitive training, social activities, and vascular risk management showed promise in healthy older adults at risk of cognitive decline. This trial aims to explore how such an intervention may change brain structure and function as well as cognitive abilities in an Asian population. Participants are randomly assigned to either a structured multidomain intervention group or a self-guided control group. The intervention group receives tailored nutritional guidance, cognitive training, physical exercises, and vascular risk monitoring, all adapted to Chinese cultural norms. The control group receives regular health education campaigns and basic health monitoring every 6 to 12 months. This trial runs for two years with ongoing assessments to evaluate the impact of these lifestyle changes. During the study, participants undergo various evaluations including cognitive tests measuring global and domain-specific cognition, neuroimaging scans like MRI and fMRI, laboratory blood tests, and physical performance measures such as grip strength and gait speed. Questionnaires assess quality of life, depression, sleep quality, and daily activities. Researchers also monitor cardiovascular health, dementia onset, and falls. This comprehensive monitoring will help determine the interventions effects on brain health and daily functioning over the 24-month period.

Researchers are developing a multicenter registry to collect and share data on pediatric patients who have undergone deep brain stimulation DBS for movement disorders such as dystonia, epilepsy, Tourette syndrome, and mood disorders. The study aims to improve understanding of DBS safety and effectiveness in children, as current data are limited and individual centers often have too few cases for strong research. This registry will support large-scale analyses and help refine DBS as a treatment option for hyperkinetic movement disorders in the pediatric population. The study involves gathering both retrospective and prospective clinical data from multiple pediatric centers. The registry will collect information on surgical techniques, patient outcomes, implant sites, and long-term effects of DBS. This collaborative data-sharing approach enables comprehensive evaluation of which patients benefit most from DBS and how it impacts their quality of life over time. Participants include children aged 0 to 18 years who have already received or are scheduled to receive DBS for neurological movement disorders. Data will be collected over five years to monitor safety, efficacy, and quality of life outcomes. The study does not involve treatment administration but focuses on gathering and analyzing clinical information. Parental or legal guardian consent is required for prospective participation.

This research aims to evaluate postoperative respiratory complications PORC in children with obstructive sleep apnea OSA who undergo adenotonsillectomy. It combines data from two centers University Hospital Antwerp and Heim Pal National Pediatric Institute in Hungary. The study examines how common these complications are and whether they vary according to different health conditions such as obesity, craniofacial malformations, Down syndrome, or neurological disorders that affect airway muscle tone. Data come from a retrospective analysis of electronic health records originally collected in two prospective studies. These records include children who had adenotonsillectomy for OSA, with postoperative care following a set protocol. The study looks at factors like the obstructive apnea-hypopnea index, oxygen levels during sleep studies, age at surgery, and presence of other health conditions to understand their relationship with PORC and to help develop a management plan. Participants information was collected without needing additional consent because it uses existing anonymized data. Researchers assess the prevalence of PORC within 24 hours after surgery and analyze how different factors affect this risk. This study does not involve new treatments but reviews existing data to improve postoperative care. The study includes children aged 1 to 18 years who had adenotonsillectomy for OSA, with follow-up limited to the immediate postoperative period.

Researchers are studying how muscle and brain interactions relate to neurodegenerative diseases NDGs such as Amyotrophic Lateral Sclerosis, Alzheimers Disease, and Parkinsons Disease, as well as aging. The study explores whether changes at the neuromuscular junction, where muscle and nerve communicate, contribute to these conditions. It aims to identify factors that influence brain-muscle connections and how these may predict disease progression or aging outcomes. This observational case-control study includes two groups a Good Aging group of adults aged 60 or older without muscle or neurological impairments, and a Bad Aging group with patients diagnosed with NDGs or severe acquired brain injury, some with sarcopenia or cognitive issues. Researchers will collect clinical and biological data, including biomarkers, microRNA, and extracellular vesicle analyses, to better understand the muscle-brain relationship and movement issues. Participants will undergo assessments including the Edmonton Frail Scale at the start and after six months to measure frailty changes. The study will gather neurological and muscular phenotyping data to track participants health trajectories. The study spans from baseline to a 6-month follow-up, monitoring physical and cognitive function to inform future clinical strategies for minimizing risks linked to aging and neurological disorders.

Researchers are studying the safety and effectiveness of a single dose of nexiguran ziclumeran NTLA-2001 compared to a placebo in people with hereditary transthyretin amyloidosis with polyneuropathy ATTRv-PN. This phase 3, multinational, randomized, double-blind, placebo-controlled trial involves about 60 participants with this nerve disease and genetic condition affecting the peripheral nervous system. Participants will be randomly assigned to receive a single intravenous infusion of either nexiguran ziclumeran 55 mg or a placebo of normal saline. To give everyone a chance to receive the study drug, participants may switch to the other treatment group at either 12 or 18 months, depending on specific study criteria. The study is designed to compare the effects of the drug and placebo over time. During the study, participants will be monitored for nerve function using the Modified Neuropathy Impairment Score 7 mNIS7 over 18 months and blood levels of serum transthyretin at 29 days and 18 months. Quality of life, body mass index, and other health measures will also be evaluated. The study includes careful safety monitoring and will last up to 18 months with ongoing assessments to track participants nerve health and overall well-being.

Researchers are conducting a Phase 3 clinical trial to evaluate the safety and effectiveness of AOC 1044, also known as delpacibart zotadirsen, for treating Duchenne Muscular Dystrophy DMD in boys aged 7 to 16 with specific gene mutations suitable for exon 44 skipping. This study is designed as a randomized, double-blind, placebo-controlled trial to assess the impact of this intravenous treatment on muscle function over time. Participants will be randomly assigned to receive either AOC 1044 or a placebo infusion every 6 weeks for 54 weeks, totaling 9 doses during the double-blind treatment period. After this, all participants can join an open-label extension where they receive AOC 1044 every 6 weeks for another 54 weeks, adding 9 more doses. Following the final dose at week 102, participants will have assessments at weeks 108 and 114 to evaluate safety and treatment effects. During the study, participants will undergo various assessments including tests for time to rise velocity, muscle strength, walking and climbing abilities, and quality of life measures. Muscle enzyme levels and global impressions of severity and change from both patients and caregivers will also be monitored. Safety and tolerability will be reviewed regularly by an independent committee. Overall participation lasts over two years, including screening, treatment, extension, and follow-up phases.

Researchers are investigating the safety and effectiveness of Bevacizumab BEV with or without microbubble-mediated focused ultrasound FUS using the NaviFUS System in patients with recurrent glioblastoma multiforme rGBM. This pivotal, randomized, open-label study compares standard care BEV alone to BEV combined with FUS in patients who have previously undergone surgery, radiotherapy, and chemotherapy with temozolomide. BEV is considered the best current treatment choice for these patients after prior therapies. Participants will be randomly assigned to one of two groups. One group will receive BEV alone via intravenous infusion at a dose of 10 mgkg over 30-90 minutes every two weeks. The other group will receive the same BEV treatment followed by administration of microbubbles SonoVue at 0.1 mLkg and focused ultrasound exposure controlled by the NaviFUS System. Treatments will continue every two weeks for up to 34 weeks or until disease progression, intolerable side effects, non-compliance, or withdrawal. During the study, participants will be monitored through regular assessments including MRI scans, quality of life questionnaires, cognitive tests Mini-Mental State Examination, and evaluation of corticosteroid use and adverse events. The primary outcome is progression-free survival at six months. Secondary outcomes include survival rates up to two years, tumor response, local disease control, and performance status. The total study participation can last up to 36 months with ongoing safety and efficacy monitoring.

Researchers are investigating epilepsy-dyskinesia syndromes, which are rare genetic diseases causing both movement disorders and epilepsy in children. This multinational retrospective survey, supported by the International Parkinson and Movement Disorder Society, aims to collect detailed clinical and molecular data to better understand these conditions. The study focuses on identifying patterns in disease features, progression, and genetic links to improve knowledge and support precision medicine. The study collects previously recorded data from multiple countries, harmonizing information on clinical features, disease progression, age of onset, genetic variants, and coexisting neurological conditions. By standardizing this data, the survey addresses challenges in rare disease research like small, dispersed patient groups and inconsistent protocols. The goal is to build a shared clinical database and analyze how movement and seizure disorders relate at both clinical and molecular levels. Participants are children aged 0 to 18 years with diagnosed movement disorders linked to specific genetic variants. The study reviews existing medical records and genetic information without new treatments or interventions. Researchers will assess the disease spectrum, how movement disorders affect quality of life, and the effectiveness of symptomatic treatments over one year. The study encourages international collaboration to advance understanding and improve care for these rare conditions.
