Filter by:The aim of the study is to improve estimation of cognitive outcome after STN-DBS in PD in order to avoid risk factors by optimizing peri- and intraoperative management personalize therapeutic strategies for optimal long-term benefit. The investigators will test possible predictors (clinical, neuropsychological, neuroimaging, electrophysiological and molecular) for the risk of cognitive dysfunction after deep brain stimulation of the subthalamic nucleus (STN-DBS) in Parkinson's disease (PD) at a single center (Charité - Universitätsmedizin Berlin, Germany). Data collection takes place prior to as well as 3, 12 and 60 months after the STN-DBS operation. Participation is proposed to all PD patients that are planned to undergo STN-DBS after careful examination of eligibility for this treatment according to standard operation procedures.
The goal of clinical trial is to learn about how blood pressure fluctuations affect cognitive performance (thinking abilities) and brain blood flow in persons with Parkinson's disease with and without orthostatic hypotension (low blood pressure when standing). The main questions it aims to answer are: - Is there a certain level of blood pressure that correlates with change in cognitive performance while upright? - Is there a certain level of change in brain blood flow that correlates with change in cognitive performance when upright? - How does cognitive performance differ between persons with Parkinson's disease that have orthostatic hypotension and those without orthostatic hypotension? - How does cognitive performance differ between the supine (laying down) and upright positions? - How do blood pressure and brain blood predict changes in cognitive performance over two years? Participants in this study will undergo the following procedures: - Complete a screening visit with questionnaires, medical history, physical exam, and head-up tilt-table test. - Attend one baseline study visit, during which they will undergo a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. Simultaneously, during the experiments we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS), a non-invasive device that uses light sensors to detect changes in brain blood flow. - Attend one two-year follow-up visit, during which they will repeat a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. During this visit, like before, we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS). Researchers will compare participants with Parkinson's disease with and without orthostatic hypotension in the laying down and upright positions to see if there are changes in thinking abilities between these groups.
The goal of this observational study is to determine whether the early adoption of blood-based biomarkers for Alzheimer's disease is associated with an impact on etiological diagnosis, patient's management, emotional impact, patient's preferences and cost-effectiveness in patients presenting with cognitive complaints in a Cognitive Disorders Unit from a public hospital. The main questions it aims to answer are: 1. Does the early adoption of blood-based biomarkers in clinical practice enable an earlier etiologic diagnosis with high confidence compared to the late adoption of blood-based biomarkers in the patients with cognitive complaints that are admitted in a Cognitive Disorders Unit? 2. Is the early adoption of blood-based biomarkers in clinical practice associated with changes in clinical management compared to their late adoption? 3. Is the early adoption of blood-based biomarkers in clinical practice associated with a lower emotional impact in the patients and their study partners/caregivers compared to their late adoption? 4. Are blood-based biomarkers better tolerated than other tests and preferred by patients for the diagnostic work-up? 5. Does blood-based biomarkers have an impact in the cost of the diagnostic workup and clinical management of the patients that are admitted in a Cognitive Disorders Unit? Participants will be asked to: - Perform a blood extraction for blood-based biomarkers analysis at the beginning of the study. - Complete specific scales in each visit. Researchers will compare the group in which blood biomarkers are delivered at 3 months with the group in which they are delivered at 9 months to assess whether early adoption of blood-based biomarkers is associated with an impact on etiological diagnosis, patient's management, emotional impact, patient's preferences and cost-effectiveness in a specialized memory unit.
This is an open-label extension for a multicenter, randomized, double-blind, sham-controlled, adaptive design pivotal study. Participants who complete the Hope Study (CA-0011) will be eligible to consent for screening to enroll in the OLE Hope Study (CA-0015). All participants will be treated with an Active Sensory Stimulation System (GS120) for 60 minutes daily for up to 12 months. There will be no Sham treatment group or randomization involved in this study.
A combination of generally regarded as safe (GRAS) compounds named GLY-LOW, which included: alpha lipoic acid, pyridoxamine, nicotinamide, piperine and thiamine, were examined in pre-clinical experiments. GLY-LOW supplementation reduced caloric intake and increased insulin sensitivity in mice. In female mice, GLY-LOW supplementation reversed aging-related declines in female hormones. Studies in humans are needed to examine the feasibility, utility and efficacy of GLY-LOW supplementation in post-menopausal women with obesity toward improving aging-related impairments. The effect of GLY-LOW supplementation on these obesity and biological age-related impairments in post-menopausal adult female humans with obesity is unknown. We aim to translate the findings of GLY-LOW supplementation in animals to a cohort of healthy, postmenopausal females at birth with obesity by conducting a one-group, no-placebo comparer, pre post intervention clinical trial. Additionally, we propose to examine the specific effect of supplementation by GLY-LOW on biological aging via retina scan. The objectives of the proposed pilot study are: I. Conduct a 6-month pilot study to examine the feasibility, utility and efficacy of GLY-LOW supplementation in a total of 40 postmenopausal female born adults > 55 years with obesity (> 30 BMI) Ia. Examine alterations in self-reported caloric intake and the following health and biological aging, parameters prior to and after 6 months of GLY-LOW supplementation: 1. Self-reported Caloric Intake 2. Metabolic disease risk 3. Cardiovascular disease risk 4. Metabolic assessments 5. Hormones 6. Physical Function and Fitness 7. Muscular strength 8. Cognitive Function and Depression assessments 9. Systemic inflammation 10. Biological aging 11. Safety parameters (also every 2 months during the intervention; ECG at baseline and 2 months only) 12, Compliance measures (pill counts and interviews every 2 months during the intervention)
The current project is dedicated to creating a comprehensive cognitive and neural assessment platform and corresponding norms tailored specifically to the older adults in Macau.
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.

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.
