Filter by:The goal of this observational study is to investigate the frequency and the possible pathogenic role of neuronal synaptic antibodies (NSAb) in patients with cognitive impairment (CI). The main questions it aims to answer are: 1. the frequency and associated features of NSAb in patients with CI and the usefulness of a clinical score in improving autoimmune dementia (AID) diagnosis; 2. the clinical significance of NSAb in patients with CI not fulfilling the autoimmune encephalitis (AE) criteria and serum NSAb (NSAb-pos-CI); 3. the impact of blood-brain-barrier (BBB) dysfunction on their pathogenicity.
This observational study aims to evaluate multiple dimensions of health in patients with Obstructive Sleep Apnea Syndrome (OSAS), before and after three weeks of ventilotherapy. Specifically, the study aims to identify pre- vs post-treatment differences in the following domains: - cognitive performance - blood expression of biomarkers related to neurodegeneration - psychosocial wellbeing Thus, patients will complete the following evaluations before (T0) and after (T1) ventilotherapy: - neuropsychological standard assessment - blood sampling - psychosocial self-reported questionnaires
Older adults suffering from a hip fracture are a significant concern, with higher incidence rates among women. Mortality rates post-hip fracture are alarming, with up to 8-fold increased risk within 3 months and significant percentages within 30 days and 12 months. Older adults with hip fracture face challenges in regaining pre-fracture level of function, especially those with cognitive impairment, which affects 25% to 40% of cases and increases mortality risk. While interventions exist, such as progressive strength training and structured exercise programs, patients with hip fracture don't consistently restore pre-fracture function, particularly in cognitively impaired patients, who are often excluded from studies. Limited evidence exists on effective management for this subgroup, with a lack of clarity on community-based rehabilitation. Although guidelines suggest exercise interventions for patients with mild to moderate cognitive impairment, the specifics remain uncertain due to insufficient research focused solely on this population. This feasibility study aims to assess the practicality and safety of implementing a 12-week individualized, progressive exercise program for older adults with hip fracture and cognitive impairment in an outpatient setting. Additionally, the investigators seek to gather qualitative insights through observations and interviews regarding participants' experiences and the perceived value of rehabilitation post-hip fracture, particularly focusing on the exercise intervention provided.
Biomarkers for Vascular Contributions to Cognitive Impairment and Dementia (MarkVCID) is an NIH-funded consortium dedicated to finding biomarkers involved in age-related thinking and memory problems. Alzheimer's disease and other dementias leave signatures on brain scans or in the blood called biomarkers. The MarkVCID study will measure a panel of candidate biomarkers in 1800 participants and watch them closely to see what they tell us about changes in brain function and risk of memory loss. Age-related problems in thinking and memory represent some of the greatest risks to public health in the US and globally. Diseases that affect small blood vessels in the brain have been shown to be major contributors to these changes. However, research and patient care can be held back by limited biomarkers that identify who should be treated. The MarkVCID Consortium includes 17 US medical centers, a Coordinating Center, an External Advisory Committee, and NIH leadership. Data and biospecimens collected as part of this research study will be stored in a research database and biorepositories, so that researchers can use this information to study brain function.
Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS) characterized by inflammation, demyelination, gliosis, and neuronal loss. Neurological symptoms may include visual disturbances, numbness and tingling, focal weakness, bladder and bowel incontinence, and cognitive impairment. Some previous studies have indicated that the NeuroBiofeedback (NBF) technique could be a promising new treatment for the rehabilitation of many neurological disorders and neurodegenerative diseases, including MS. Several studies have investigated the beneficial effects of this technique on the motor and cognitive outcomes of MS, mainly aiming to evaluate motor performance, fatigue and chronic pain. Few studies have focused on the evaluation and treatment of cognitive processes with NBF, except for one study on information processing speed. Specifically, regarding the application of NBF techniques in MS, recent literature has demonstrated that modulation of the alpha-theta rhythm has led to an improvement in attentional processes with consequent reduction in anxiety. Therefore, the objective of this study is to verify the effectiveness of NBF training on the modulation of cortical activity and physiological responses through the exposure of subjects with MS to cognitive tasks and training for mood regulation.
TITLE: Whole genetic approach in Early Genetic Identification of Obesity (WEGIO) DESIGN: Multicenter epidemiological study STUDY POPULATION: Participants at risk for a syndromic or a monogenic genetic obesity, incl. participants clinically diagnosed with Bardet-Biedl-Syndrome (BBS) NUMBER OF PARTICIPANTS: 1000 for initial genetic sequencing and app. 40 for the follow-up documentation COORDINATING INVESTIGATOR: Prof. Dr. Arndt Rolfs
This study seeks conduct a pilot study to test whether a cognitive training program can improve processing speed abilities in individuals with acute traumatic spinal cord injury.
The goal of this clinical trial is to investigate the impact of daily self-administered transcranial direct current stimulation (tDCS) therapy on the cognitive function of individuals with moderate to severe cognitive impairment resulting from a traumatic brain injury (TBI). The study aims to answer the following questions: Does daily self-administered tDCS therapy, when combined with computerized cognitive training (CCT), improve cognitive function in TBI patients? Is CCT+tDCS with anodic stimulation more effective than CCT+tDCS with simulated stimulation in enhancing immediate and one-month post-treatment cognitive function? Does CCT+tDCS with anodic stimulation lead to better functionality immediately and one month after treatment compared to CCT+tDCS with simulated stimulation? Does CCT+tDCS with anodic stimulation have a positive impact on mood improvement immediately and one month after treatment compared to CCT+tDCS with simulated stimulation? Participants in the study will engage in CCT through a smartphone or tablet application and self-administer tDCS therapy for 20 minutes each day for a duration of one month. The tDCS therapy will involve applying a 2 mA anodic current to the prefrontal dorsolateral cortex (PFDL). Prior to the intervention, patients or their caregivers will receive training on the proper and safe usage of the tDCS device. Cognitive function, mood, and functionality will be evaluated before and after the intervention using appropriate measurement scales. The outcomes of this clinical trial have the potential to identify an effective and accessible therapeutic approach to enhance cognitive function in individuals with moderate to severe TBI. The combination of tDCS therapy with CCT offers an appealing and feasible treatment strategy for these patients, particularly when conducted in a home setting. The findings from this study will guide future clinical trials in the field of cognitive rehabilitation for TBI patients. Researchers will compare active tDCS with sham tDCS to determine if there are differences in the primary outcomes mentioned.
The proposed research is a randomized crossover trial designed to assess changes in postprandial cognitive function and the gut-brain axis in adults with subjective cognitive complaints who consume 1 study snack per day for 1 week.
To provide detailed information on long-term outcomes in relation to potential neuroprotection and improvements in recovery for different targets of sedation, temperature, and pressure management in post out of hospital cardiac arrest survivors at 6 and 12 months. In addition, the impact of caring for a post OHCA survivor will be explored.
