Filter by:Participation in medical research usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This trial will admit a wide range of data on the clinical trial experience of mild cognitive impairment patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future mild cognitive impairment patients.
Early cognitive assessment of critically-ill acute respiratory distress syndrome (ARDS) patients with delirium using a multidimensional electrophysiological evaluation battery (mEEG) to identify and characterize the neural correlates of cognitive dysfunctions associated with delirium (vigilance, attention, semantic and lexical processing, self-processing), and to develop a prognostic evaluation of neurocognitive and psychological disorders using an innovative non-behavioral approach.
The 32 million Alzheimer's disease (AD) and 69 million prodromal AD patients worldwide contribute to a large economic burden. Effective and safe therapies that slow or prevent the progression from mild cognitive impairment (MCI) to AD are therefore of high priority. Transcranial alternating current stimulation (tACS) is a safe and patient-friendly non-invasive brain stimulation technique that serves as a potential candidate for reducing and/or slowing cognitive impairment. Application of tACS in the gamma frequency range, specifically around 40 Hz, has been studied in patients with AD and MCI due to AD. In these patients, a single session of 40 Hz tACS at the precuneus showed to improve episodic memory and to increase gamma power, as measured with electroencephalography. These findings will be replicated in the current study in patients with MCI due to AD, using magnetoencephalography (MEG) recorded before, during and after tACS. In this way, brain activity and network changes that underlie this improvement in episodic memory can be studied with greater temporal and spatial detail.
The goal of this randomized pilot trial is to test a chronic pain self-management program customized for people living with both chronic pain and cognitive impairment. The main questions it aims to answer are whether this program is feasible and acceptable, and whether it shows potential for improving pain-related outcomes. Intervention group participants will receive education and support from a community health worker in 7 weekly telephone sessions, and will watch a series of educational videos discussing a variety of chronic pain self-management skills. A control group will not receive the program, but after the final data collection point will be invited to attend a one-time remote session that summarizes intervention content, and will receive all program materials. Researchers will compare intervention and control groups after the program ends to see if the intervention group has less pain interference with daily activities.
Primary objective - Collection of patients with wilson disease either presented with neurological or hepatic symptoms - Assessment of psychiatric and cognitive disorders in both groups by using specific scales Secondary objective - correlation of MRI brain findings with cognitive & psychiatric symptoms found in the patients ,if possible.
This is a randomized, double-blind, placebo-controlled, parallel group study. The use of placebo is appropriate to minimize bias related to treatment expectations of the subject, study partner, and site investigator, as well as to changes in the relationship between the subject and study partner that might occur with the initiation of treatment and expectation of improvement in motor symptoms or cognition. Changes in subject/study partner interactions can impact subject mood and might introduce biases that cannot be quantified. The double-blind use of placebo will also prevent bias in the clinical and scientific assessments.
This is a single-center, randomized controlled clinical trial with a parallel-group design conducted at Minia University hospital.
This study is a mechanistic randomized controlled trial that investigates whether inhibition of tumor necrosis factor signaling via intravenous infusion of infliximab improves psychomotor speed and executive functioning in depressed individuals who exhibit an inflammatory phenotype.
This study will evaluate a new form of non-invasive deep brain therapy for individuals with Alzheimer's disease. Low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial. The trial will evaluate brain target engagement using magnetic resonance imaging, PET imaging, and numerical scales of cognitive performance.
The goal of this observational study is to learn the how to determine the mean arterial pressure(MAP) or blood pressure level to be maintained during non-cardiac surgery for optimal brain health in patients above the age of 60 undergoing major non-cardiac surgery. The main question[s] it aims to answer are: - Is there a way to tailor the blood pressure to be maintained in such patients during surgery for optimal brain health using non-invasive monitors that check the brains electrical activity, the electroencephalogram(EEG) monitor, and the brain's blood oxygen levels, the cerebral oximetry(CO) monitor? - How much does this optimal blood pressure level vary between patients? Participants will be asked to: - Complete a questionnaire at the time they enroll into the study, as well as a daily questionnaire to help determine their level of thinking and brain health. This questionnaire will be administered by a member of the study team. - They will also have an EEG and CO monitoring sticker placed on their foreheads. This will be connected to a monitor that will collect this data just before, during, and after their surgery. The data collected through these monitors will help us with our study goals.
