Filter by:The goal of this clinical trial is to investigate the possibility of rehabilitation of mild cognitive deficits in people with metabolic syndrome. We aim to implement a cognitive training program on patients with metabolic syndrome and cognitive deficits, and examine its effectiveness both post-intervention (3 months) and after 12 months. Researchers will compare two groups, the experimental group that will receive the computerized cognitive training and the control group that will receive no training.
This clinical trial aims to explore the effectiveness and safety of cognitive function improvement of Neuclare, a science medical device, for patients with mild cognitive impairment and early Alzheimer's disease. Through methods such as Trail Making Test Black & White, Attention Questionnaire Scale(AQS), Neuropsychiatric Inventory (NPI), etc, cognitive function improvement before and after using Neuclare will be evaluated.
Sickle cell disease (SCD) is a common, inherited blood disorder that primarily affects people of African Ancestry. It has a lot of complications including neurological complications. The neurological complications of SCD are particularly devastating and lead to cognitive decline even in the absence of overt brain injury. In such cases, it is thought that inflammation in the brain maybe partly responsible for the cognitive decline. The main reasons for this research study are to see 1) how safe and 2) how well minocycline works to try to stop/reverse cognitive decline in people with SCD. People with SCD are at risk for changes in their brain over time that can cause problems with learning, memory, and attention. Part of the reason for this is inflammation within the brain. Minocycline may be able to stop these brain changes by stopping this brain inflammation. Minocycline is a second-generation tetracycline antibiotic that has been shown to both inhibit neuroinflammation and improve cognitive function in a variety of neurodegenerative and psychiatric disorders but has not yet been studied in SCD. We are proposing here, a pilot double-blinded, randomized controlled trial to examine the tolerability and early efficacy of minocycline in adults with SCD at two dosing regimens (200 mg and 300 mg daily) versus placebo over one year. Participants will undergo a neuropsychological exam using the NIH Toolbox Cognition Battery at both study enrollment and exit (after one year) to assess for changes/stability of cognition. Participants will receive monthly phone calls/text messages to assess for adverse events and will be seen every three months for pill counts and routine laboratory monitoring. The primary outcome will be a comparison of adverse events across the two dosing strategies versus placebo. Early evidence for cognitive benefit will also be assessed from the results of the NIH Toolbox.
Background: Creatine transporter deficiency (CTD) is a genetic disorder that mainly affects the brain in males. CTD causes intellectual disability that can be mild to severe. People with CTD may have seizures and behavioral issues. They may have slow growth and tire easily. CTD may sometimes be confused with autism or other disorders. Better diagnostics are needed. The study team in an NIH study noted that the faces of children with CTD can look similar. For this natural history study, an expert will examine photos of children with CTD. Any shared traits found might help to diagnose CTD. Objective: To look for shared facial features of children with CTD. Eligibility: Males aged 2 to 40 years old with CTD who were in study 17-CH-0020. Design: Some participants in study 17-CH-0020 had pictures taken of their faces. The NIH study team wants to share these photos with a colleague in Canada. This person is an expert at evaluating how genetic disorders affect people s bodies. Participant data collected during the study may also be sent to this expert. This data may include diagnostic images and results from lab tests. Some children did not have their pictures taken during study 17-CH-0020. Parents are asked to take pictures of these children and send them to the study team. These photos can be sent to a secure portal. The photos can also be taken in-person during a clinic visit. The photos may be printed in clinical study journals. But this is not required. Parents will be asked to sign a separate consent before the photos are published.
Negative symptoms and cognition decline are major challenges in clinical management of schizophrenia. Dorsomedial prefrontal cortex (DLPFC) has been highly involved in the mechanisms of negative symptoms and cognitive symptoms of schizophrenia. However, the effect of repetitive transcranial magnetic stimulation (rTMS) over left or bilateral DLPFC has not yet been well studied. The aim of this study is to describe how the effectiveness of rTMS over different targets for cognitive deficits and negative symptoms in schizophrenia will be evaluated. The study will provide evidence to determine whether a bilateral DLPFC rTMS and is more effective than a left DLPFC rTMS alone to optimize treatment protocol in schizophrenia.
The proposed project will assess long-term changes to health/lifestyle, advanced planning, and research engagement that Black and White patients with Amnestic Mild Cognitive Impairment (aMCI) make following disclosure of positron emission tomography-based amyloid and tau burden and associated risk of conversion to Dementia-Alzheimer's Type. Healthcare access will be explored as potential barrier to or facilitator of behavior change.
This study aims to determine the feasibility of a randomized-controlled trial of digital cognitive behavioural therapy for insomnia (CBT-I) for sleep and cognitive performance in older adults with MCI and insomnia symptoms (50-80 years). The trial will be completed online, and participants will be recruited from the community across Australia.
There are over 50 million people living with dementia, and by 2050, the number is expected to rise to 152 million worldwide. Mitochondrial dysfunction in the brain of MCI and AD patients is gaining prominence as a potential mechanism and thus treatment target. However, an effective therapy targeting mitochondrial function, is still missing. Photobiomodulation (PBM), is an innovative noninvasive technique that delivers transcranial near infrared light to the brain. PBM is thought to play a key role in enhancing mitochondrial function [especially in tissues with a high number of mitochondria (e.g.,brain)], by reducing oxidative stress and increasing ATP levels. PBM can be safely administered to awake outpatients and does not require general anesthesia or surgical implantation. Recent animal studies, and case studies suggest that PBM is a promising therapy for AD. However, due to the lack of placebo controls and objective blood and neuroimaging biomarkers, the effectiveness and mechanism of action of PBM (via enhancing mitochondrial function) in AD remains to be studied. Objectives: The investigators aim to evaluate cognitive changes and neural correlates associated with PBM in early amnestic MCI (aMCI) during a pilot feasibility study. Participants who meet study criteria will undergo a 6-week trial of home-used PBM using the Neuro Rx Gamma 6days/week, 20 minutes per session (n=20). All patients will undergo clinical and cognitive assessment, blood sample collection, and structural and resting state functional MRI scans in two timepoints; pre and post treatment. The longitudinal nature of the study will allow investigation of the PBM effect and its' neural correlates in aMCI via enhancement of mitochondrial function. The present study provides a unique opportunity to investigate the mitochondrial and neural mechanisms that may be involved in prevention or delay of cognitive decline in aMCI.
The main objective of this non-interventional, propective and multipercentric study is to Assess the evolution of caregiver burden 1 month after their elderly relative's Emergency Department (ED) admission
Lifetime risk for developing an alcohol use disorder increases with earlier onset of alcohol consumption. This risk may reflect a tendency for escalated alcohol intake among youth due to immature executive control, leading to more frequent binge drinking, which is associated with more alcohol-related problems. Binge drinking is associated with deficits in behavioral flexibility, which may suggest impaired control networks that contribute to automatic behavior. Individuals with an alcohol or substance use disorder (A/SUD) exhibit attentional bias toward drug- or alcohol-related stimuli that have attained salience through consistent use. Reward history increases attention towards non-drug stimuli, even among individuals with no lifetime A/SUD. Preliminary data (from Dr. Boettiger's lab) from a nationally representative US adult sample using data collected via Prolific found that a questionnaire measure of mindfulness moderates the relationship between alcohol misuse and attention to reward. Given evidence that heavy alcohol drinking impairs behavioral flexibility, which in turn promotes escalating intake, insight into the relationship between mindfulness and behavioral flexibility could inspire new strategies to prevent alcohol and substance use disorders in people at elevated risk.
