Active clinical trials for "Cognitive Dysfunction"

Amyloid plaques and tau protein are the landmarks of neurodegeneration in Alzheimer's disease (AD). On the other hand, it is reported that cerebral ischemia may induce amyloid plaques and tau protein accumulation. However, it was difficult to in vivo disentangle the complex and dynamic interactions between AD pathophysiology and cerebral vascular injury in the development of post-stroke cognitive impairment in the past. With the advent of novel radiotracers specific to cerebral amyloid plaques and tau protein, we aim to conduct a prospective multimodal neuroimaging cohort study to investigate the contribution of vascular injury, amyloid plaques and tau protein to stroke recovery and post-stroke cognitive impairment.

This smartphone-based personalized multiple intervention study aims to prevent cognitive impairment and reduce dementia and cerebrovascular events in 45-74 year old persons with high risk of stroke in China. The investigators plan to monitor and manage participants' behavioral and health (vascular risk factors control, sleep quality, mental health and cognitive training) based on self-monitoring and personalized feedback via smartphone app. The short-term primary outcome is 1-year change in global cognitive score measured by a modified National Institute of Neurological Disorders and Stroke and Canadian Stroke Network-Canadian Stroke Network protocol. The investigators hypothesize that the intervention based on self-monitoring and personalized feedback will prevent cognitive decline by the initial 1-year intervention. The long-term primary outcome is the development of dementia and cerebrovascular events during a total of 5 years' follow-up. The investigators hypothesize that the smartphone-based personalized multiple intervention may reduce the 5-year risk of dementia and cerebrovascular events, mainly through the improvement in vascular risk factors control, sleep quality, mental health and cognitive training activities.

This study will probe if the biological changes in amnestic mild cognitive impairment (aMCI) are related to a history of mild traumatic brain injury (mTBI) using high definition transcranial direct current stimulation (HD-tDCS) and blood-derived biomarker tools. Participants who Do as well as those who Do Not have a history of mTBI will be enrolled in the study.

The goal of this clinical trial is to compare conventional clinical data collected as part of usual practice with data collected by the two digital tools to help diagnose major and minor neurocognitive disorders in elderly people consulting a memory center for cognitive complaints. The main question[s] it aims to answer are: Is it possible to create a classification between the different intensities of cognitive impairment? Is it possible to create a diagnostic tool consistent with the reference diagnosis? Participants will be asked to complete a series of cognitive and fine motor tasks, and will be given questionnaires on their lifestyle and medical history. They will be asked to wear a connected watch for 1 week. There is no comparison group.

This study is to investigate whether the improvement or maintenance of cognitive function is superior to the control group when gum chewing is performed in elderly people with subjective cognitive decline or mild cognitive impairment.

The study utilizes investigational software, the SPARK Test, with an FDA-cleared electroencephalography (EEG) amplifier and EEG cap to collect and then analyze patient EEG data.

Dementia, especially dementia caused by Alzheimer's disease, is considered one of the most severe health problems of our time. It is currently known that the disease begins many years before clinical symptoms appear. The sooner the patient is diagnosed, the sooner the patient will be in a position to prevent further deterioration. A recent orientation is the analysis of language in relation to the description of images with a high and varied semantic and emotional content. It can be studied that changes in the description of an image check if these changes are associated with the evolution of a person with probable impairment both in memory and cognitive as well as emotional, psychiatric, behavioral and even in their interaction with environmental factors especially those associated with socialization and loneliness. Thus, the purpose of this study is to validate speech analysis AI models.

The primary goal of this project is to evaluate feasibility and acceptability of the MIND+SOUL diet and its implementation. Secondary goals of this project are to evaluate cardiovascular risk profile, nutritional health status, and cognition in relation to the MIND+SOUL diet intervention.

This study will test whether a physical activity intervention can improve cognition in breast cancer survivors and help the development of physical activity guidelines for cognition in breast cancer survivors.

This project is aimed at the discovery of neuro-modulation techniques that may alleviate chemotherapy induced cognitive deficits (CICD), especially in executive (higher-order) cognitive function (EF).
