Huntington Disease

The 100-Year Human Aging Study is a long-term observational research project enrolling adult participants to undergo detailed multi-system health screenings and follow them throughout their lives until death. The study aims to identify which health measurements taken at enrollment and repeatedly over time can predict overall mortality, cause-specific death, serious diseases, and functional disability. It addresses the current lack of validated longevity measures by generating data on how various physiological and cognitive functions relate to aging outcomes. Participants undergo a comprehensive clinical screening that includes tests of cardiorespiratory fitness, strength, mobility, neurocognitive performance, sensory functions, and metabolic health. Structural imaging assessments like DEXA scans, echocardiography, electrocardiography, spirometry, retinal photography, and vascular ultrasound are performed. Laboratory tests and detailed medical, social, and environmental histories are also collected. The study allows participation from single tests up to a full two-visit screening, with repeat testing encouraged to track health changes over time. Throughout the study, participants receive individualized reports with investigational estimates of biological age and predicted mortality risks, which are being evaluated against actual health outcomes. Researchers collect data continuously on mortality, disease occurrence, disability, and health behavior changes. The study involves ongoing follow-up with periodic assessments and aims to preserve all collected data for future analyses, with participant involvement potentially spanning their entire lifespan.

This research focuses on elderly patients hospitalized in Continuing and Rehabilitation Care Units, many of whom suffer from neurodegenerative diseases and need personalized rehabilitation care. The study evaluates the use of ergonomic cutlery handles tailored to patients hand grip ability, aiming to improve their autonomy during meals and potentially reduce malnutrition risks. These custom handles are made using 3D printing technology, offering a lightweight and inexpensive alternative to standard adapted cutlery. Participants will start with a functional and joint assessment of their hand to determine the optimal diameter for the cutlery handles 25, 30, 35, or 40 mm. Their autonomy in eating and the amount of food consumed will be measured at three lunch times before using the adapted handles Day 0, the first lunch using the handles Day 1, and after three days of use Day 3. Ergotherapists will also assess upper limb compensations during meals without and with the technical aid. Throughout the study, participants autonomy in eating is evaluated using the Katz scale, with additional assessments by ergotherapists and dieticians. The study tracks changes in food intake and physical compensations over three days, ending after the Day 3 assessments. The main outcome measured is patients food autonomy at Day 1, with secondary outcomes including autonomy and food intake at Day 3 and upper limb compensations. Participation lasts only through the initial assessment and the three-day intervention period.

Researchers are investigating the effects of deep brain stimulation DBS on brain function in patients with various neurological and psychiatric disorders, including Parkinsons disease, essential tremor, dystonia, depression, epilepsy, neuropathic pain, and Alzheimers disease. This prospective cohort study aims to use advanced MRI techniques, particularly functional MRI fMRI, to better understand how DBS influences brain circuits and to explore whether fMRI can aid clinical practice in managing DBS therapy. Participants in this study include patients who will undergo or have already undergone DBS electrode placement. The study involves performing structural MRI scans using 1.5 Tesla or 3 Tesla machines as well as resting state and task-based fMRI scans. DBS patients will be scanned while their devices are programmed at different stimulation settings, including switched off and switched on states. The fMRI results will be shared with clinicians to help guide DBS programming decisions. During the study, participants will have multiple brain scans from three months before DBS implantation to one year after. Researchers will assess brain areas activated by DBS, examine structural and functional brain connectivity through MRI, and monitor clinical outcomes. The study includes regular evaluations to observe how DBS impacts brain function over time, aiming to improve post-operative follow-up and optimize treatment for these patients.

Researchers are evaluating the use of 18FNIDF PET imaging to visualize abnormal tau protein pathology in the brains of living humans. This technique targets tau neurofibrillary tangles, which are linked to neurodegenerative diseases such as Alzheimers and other tauopathies. The study focuses on assessing the safety and diagnostic effectiveness of this imaging agent, which may offer advantages over existing tau PET tracers due to its stronger binding and lower off-target effects. Participants will receive a single intravenous injection of approximately 10 b1 3 mCi of 18FNIDF. Following the injection, a PETCT scan will be performed to capture images showing the distribution of the tracer in the brain. The study includes both healthy volunteers and patients with cognitive impairment or probable Alzheimers disease. There is only one main study period involving this single injection and imaging session. During the study, participants will be monitored for safety from the time of injection up to seven days afterward. The primary assessments include safety evaluation and measuring how the tracer spreads in the body during the PETCT scan on the injection day. Researchers will also evaluate the diagnostic performance of the imaging over a two-week period from enrollment to the end of imaging. Participants involvement is limited to the injection, scanning, and follow-up safety checks.

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.

Researchers are conducting a first-in-human, multi-center clinical trial to study the effects of SRP-1005 in people with Huntingtons disease HD. The trial is designed to evaluate the safety and impact of SRP-1005, a drug given by subcutaneous injection, compared to a placebo. The study includes adult participants aged 21 to 70 years who have a genetically confirmed diagnosis of HD and are at specific disease stages. Participants will be randomly assigned to one of four groups receiving different doses of SRP-1005 or a placebo. The study is double-blind, meaning neither the participants nor the researchers know who receives the drug or placebo. The treatment period includes dose escalation and monitoring to assess the drugs presence in plasma, urine, and cerebrospinal fluid over several weeks. During the study, participants will be monitored for side effects and adverse events from baseline through 24 weeks. Researchers will collect blood, urine, and cerebrospinal fluid samples to measure drug levels and safety. Participants must agree to use effective contraception if applicable, and the study excludes those with certain infections, other neurological illnesses, or conditions that prevent safe lumbar puncture or MRI. The total participation lasts at least 24 weeks with ongoing safety assessments.

Researchers are evaluating a low-cost augmented reality platform for balance training in patients with balance disorders caused by degenerative injuries or cerebrovascular diseases. The study aims to determine if the system is usable, acceptable, safe, and if it improves balance. The trial is a usability study conducted by the Hospital Universitari Vall dHebron Research Institute. The intervention has two phases the first phase lasts four weeks with supervised balance training sessions at the hospital, conducted for 60 minutes, three times a week. If patients meet inclusion criteria, the intervention continues for two additional weeks at home with a family member trained to assist as a training partner. The platform uses different exercise protocols accessed through RGSweb, including balance and sit-to-stand exercises with visual targets and movement tracking. Participants undergo three assessments before treatment Day 0, after the hospital phase Week 4, and after the home phase Week 6. Evaluations include usability scales, adherence measures, balance tests like the Berg Balance Scale, postural sway, sit-to-stand tests, balance confidence, and quality of life questionnaires. Safety is monitored throughout, and adherence is tracked during both hospital and home interventions.

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.
