Active clinical trials for "Cognitive Dysfunction"

The purpose of this study is to investigate the effects of transcutaneous vagus nerve stimulation (t-VNS) on Long Covid symptoms in females and to identify factors influencing susceptibility and recovery-particularly in the cognitive domain, as over 80% of long-haulers experience "brain fog".

The main objective of the study is to evaluate the efficacy of a combined training program of physical exercise and multisensory stimulation (Physiocognitive Integration) in people with mild/moderate cognitive impairment.

This project is focused on conducting a home-based, thinking while moving exercise intervention for adults 65 years or older, who have mild cognitive impairment, that will integrate several effective training modalities including non-contact cardio-kickboxing, stepping exercise, balance/functional training, and muscle strengthening. Cognitive function, physical function, and dual-task abilities will be assessed over the 12-week intervention and comparisons will be made between participants in the exercise intervention and control participants receiving no intervention.

This trial attempts to evaluate the effects of intensive transcranial direct-current stimulation (tDCS) on improving cognition in schizophrenia patients and changes in resting state brain network connectivity, especially increasing connectivity in the tasks related network, and increasing activation the DLPFC in a working memory task. Half of the participants will be randomized to tDCS group, while the other half will be randomized to receive sham tDCS.

This study is aimed to investigate the efficacy of an 12-week Chinese calligraphy training program for enhancing cognitive and emotional functions of older adults with mild cognitive impairment. Participants are tested with several cognitive tests and electroencephalography (EEG), psycho-physical parameters and brain activities are recorded. Results are compared at pre-intervention, post-intervention, and 6-month post-intervention to provide evidence of benefits of Chinese calligraphy practice.

The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of SUVN-D4010 in healthy male subjects following single or multiple ascending doses.

This study is to investigate the effectiveness of computerized cognitive training, and corresponding neural substrates through multimodal neuroimaging assessment, in the elderly with normal cognition, subjective cognitive impairment, and mild cognitive impairment.

A DIGITAL THERAPEUTIC TO IMPROVE THINKING IN MULTIPLE SCLEROSIS WHO: 65 participants with a confirmed diagnosis of Multiple Sclerosis (MS) WHY: Purpose of the study is to compare the effect of 2 tablet-based brain training digital tools on important components of thinking (cognition). WHAT: Complete a set of tests (physical and cognitive) at baseline, 6 weeks and 14 weeks, and use one of two brain training tools on an iPad in your home, for 25 minutes a day, 5 days a week, for 6 weeks. WHERE: UCSF WEILL INSTITUTE FOR NEUROSCIENCES (675 Nelson Rising Lane, San Francisco, CA)

This study will recruit patients more than 65 years old eligible for non-cardiac surgery. Patients who participate will take either vitamin B12 and folic acid supplementation or placebo for 7 days before surgery. Neuropsychological test battery (NPB) will be tested before intervention and at discharge for determination of Post operative cognitive dysfunction (POCD). Another group of non-surgical elderly participants will also be tested for NPB to account for learning effect in POCD diagnosis. The hypothesis is that preoperative vitamin B12 supplementation will reduce the incidence of POCD in elderly patients undergoing non-cardiac surgery.

The purposes of this study are: To investigate whether a 3-month exercise training program would improve cognitive function, motor performance, integrity of brain fiber tracts and cerebral blood flow; To investigate the possible neuro-anatomical and neurophysiological mechanisms of exercise training on cognitive function, motor performance, integrity of brain fiber tract and cerebral blood flow in patients with mild cognitive impairment and in those with early Alzheimer's disease; To investigate the influence of different apolipoprotein E (APOE) genotypes on the above-mentioned exercise effects. The results of this study will provide medical evidence for the effects of exercise training on mild cognitive impairment and on early Alzheimer's disease; and will provide understanding of the mechanisms mediating these effects. More importantly, the results serve as the basis for future larger-scale exercise clinical trials for these two patient populations.
