Filter by: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 interventional non-pharmacological study is to investigate the effects of a multi-domain intervention ( "active intervention"), compared to that followed by normal clinical practice ("self-guided intervention"), in older adults. The primary objective is whether these interventions can prevent functional and cognitive decline in at-risk subjects. The multi-domain interventions will include physical exercise, a Mediterranean diet-based nutritional plan, cognitive training, regular medical check-ups, oral hygiene treatments and counseling, monitoring and counseling on visual and auditory abilities, counseling on sleep hygiene and treatment, control of cardiovascular, metabolic, and infectious risk factors, adjustment of drug therapy, suggestions for improving social interactions.
The investigators aim to conduct a randomized controlled trial to compare two symptom-management programs for Black older adults with early cognitive decline (self-reported confirmed by testing) and chronic pain. The programs are Mindfulness-Based Cognitive Therapy with Walking (MBCT+w) and Active Living Every Day (ALED). The investigators will assess how each program may help in improving physical, cognitive, and emotional function. The investigators will also assess whether improvements in outcomes from the two programs are maintained through a 6-month follow-up.
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.
This study is being done to assess the feasibility of administrating Δ9-THC and Δ8-THC isolates and simultaneously adopting several data harmonization measures to generate uniquely translatable data. This project aims to (1) evaluate the feasibility and acceptability of administering ∆9-THC and Δ8-THC isolates using standardized cannabis dosing units to quantify ∆9-THC and Δ8-THC pharmacokinetics; and (2) evaluate the feasibility and acceptability of adopting standardized impairment detection methods and driving performance definitions and measures on quantifying ∆9-THC and Δ8-THC driving impairment compared to a placebo.
The goal of this clinical trial is to learn about breast cancer patients. The main questions it aims to answer are: - Does Aerobic Dance During Chemotherapy Improve Cognitive Function in Breast Cancer Patients？ - Does the efficacy of aerobic dance differ from fast walking of equal intensity？ Recruited patients will be randomly assigned to three groups: (1) aerobic dance group, (2) fast walking group, and (3) usual care group. The aerobic dance and fast-walking groups participated in supervised exercise lasting 50 minutes thrice a week for 12 weeks. The goal of this study's findings is to develop practical strategies for managing breast cancer-related cognitive impairment.
In the past three years, in the general intensive care unit in Meir medical center, 25 patients were treated with ECMO, of which two patients were treated with VA ECMO and the rest with VV ECMO. 70% of the patients survived to hospital discharge. ECMO is indicated as a rescue therapy for patients in critical condition suffering from severe cardiac and/or respiratory failure that does not respond to conservative treatment. It can be used as a bridge to recovery or to heart/lung transplantation. ECMO was introduced in the late seventies of the pervious century. Between the years 2006-2011, partly due to the outbreak of the flu epidemic (H1N1), a 433% increase was observed in the use of ECMO worldwide in adults. In light of the outbreak of the Covid-19 epidemic in recent years, another significant increase has been observed. There are short-term and long-term complications of ECMO. Short-term complications include bleeding, thrombosis, hemolysis, HIT, renal and neurological injuries, associated infections, and technical-mechanical problems. Long-term complications include significant physical and psychological consequences that may adversely affect the patient's daily function, especially executive function.
Older veterans with a history of mild brain trauma exhibit early cognitive challenges, especially in driving-related tasks. This is attributed to alterations in the brain's excitatory/inhibitory (E/I) balance. This pilot project investigates this phenomenon by leveraging electroencephalography (EEG) to measure parietal lobe alpha rhythms during visual attention tasks. The hypothesis is that targeted visual attention training can modulate these alpha rhythms, improving instrumental activities in daily life. However, outcomes from such training vary, possibly due to individual differences in cortical inhibitory functions. This study will assess the relationship between EEG measures of E/I balance pre- and post-visual attention training and its effects on processing speeds in aging veterans. Our findings aim to provide a foundation for customized therapies and interventions for veterans with and without a history of brain trauma.
This study is aimed at improving health outcomes for adolescents who sustain sport and recreation related concussions (SRRC) by enhancing Return to Learn (RTL). The study will conduct a quasi-experimental school-based 2 phase study involving 200 students with SRRC. The first phase will be descriptive to evaluate current standards (n=50). Phase 2 will compare students whod receive either standard of care RTL (n=75) or RTL augmented by a communication tool (RTC+; n=75).
This is a national monocentric (San Raffaele Hospital - OSR, Via Olgettina, 60, 20132 Milan, Italy) observational low-risk-intervention study, prospective and multiparametric (clinical, EEG, neuropsychological evaluations) study. Patients with a diagnosis of DRE and DSE will be screened to evaluate their eligibility. They will undergo clinical and cognitive assessments in addition to 32channel EEG at baseline (T0). DRE patients will also undergo clinical and cognitive assessments, and 32-channel EEG at 6 months (T1), and 12 months (T2). Patients newly diagnosed with focal cryptogenic epilepsy (NDE) will undergo clinical and cognitive assessments, and 32-channel EEG at baseline (T0), at 6 months (T1), and 12 months (T2). High-definition EEG will be performed to investigate patterns of cortical sources and functional connectivity alteration specific to DRE and DSE and to explore their prognostic value. Longitudinal EEGs will be acquired to explore the evolution of EEG patterns. Cognitive evaluation will be performed by an experienced neuropsychologist. At baseline, DRE, DSE, and NDE patients will undergo a screening and a comprehensive cognitive battery in order to define performance differences among groups. The DRE and NDE group only will perform the same neuropsychological assessment at month 6 and 12 for monitoring the potential progression of cognitive and/or behavioural disturbances in these patients.
