Filter by:The ACE Trial, funded by the National Institute on Ageing/National Institutes of Health (NIH), is a multicenter clinical trial. The ACE Trial will determine if taking the dietary supplement Equol could slow the progression of stiffening of the arteries, small blood vessel disease in the brain and memory decline. Equol is a soy-based supplement that has plant estrogen-like compounds in it. Equol is a metabolite of soy isoflavone. Our studies in Japan and other studies suggest that Equol may slow mechanisms related to memory decline. No previous studies in the United States have tested the effect of Equol on these mechanisms or memory decline. Supplementation of Equol in the ACE Trial is approved by the Food and Drug Administration (FDA). Researchers at the University of Pittsburgh, Pittsburgh, Pennsylvania, Wake Forest University, Winston-Salem, North Carolina, and Emory University, Atlanta, Georgia, are recruiting participants. The ACE Trial will ask participants to complete 7 clinic visits over a two-year period. The participants are asked to take Equol tablets daily for 24 months. Clinic procedures include Pulse Wave Velocity (to measure arterial stiffness), Magnetic Resonance Imaging (MRI) of the brain and tests of awareness and thinking.
In this randomized controlled trial the effect of 4 months of multi-component (strength, balance, cognition, endurance) exercise training intervention on measures of neuromuscular performance, cognition, and endurance as well as neural adaptations on a central and peripheral level is investigated. 40 subjects are recruited that are generally health and between 60 and 80 years of age. The interventions is based around exercises, where different tasks have to be solved simultaneously rather than serially, as has previously been done.
This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Approximately 530 subjects will be randomized to 12 months of daily treatment with either Active or Sham Sensory Stimulation Systems. Efficacy will be measured using the Alzheimer's Disease Cooperative Study- Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) of the ADCS-ADL and the Mini-Mental State Exam (MMSE).
Our study intends to offer 'real world' evidence of a viable, sustainable means to mobilize primary care via a comprehensive strategy for detecting cognitive impairment and dementias, advancing next steps for referral, and participating in the care planning and management of affected patients and caregivers. We will conduct a clinic-randomized, pragmatic trial testing the effectiveness and fidelity of our NIH Toolbox-derived paradigm to improve early detection and management of cognitive impairment/dementia in primary care settings serving health disparate patient populations.
Alzheimer's disease (AD) has a presymptomatic course which can last from several years to decades. Identification of subjects at an early stage is crucial for therapeutic intervention and possible prevention of cognitive decline. Current research is focused on identifying characteristics of the early stages of AD and several concepts have been developed to that end. Subjective cognitive decline (SCD) is defined as a self-experienced persistent decline in cognitive capacity in comparison with the subject's previously normal status, during which the subject has normal age-, gender-, and education-adjusted performance on standardized cognitive tests. SCD is not related to current cognitive impairment, however it has been considered for its potential role as risk factors for AD. The aim of this study is to evaluate, through machine learning tools, the accuracy data, neuropsychological assessment, personality traits, cognitive reserve, genetic factors, cerebrospinal fluid (CSF) neurodegeneration biomarkers, EEG and Event Related Potential recordings in predicting conversion from SCD condition, to Mild Cognitive Impairment (MCI) and AD.
Dementia currently affects more than 47 million people worldwide, its prevalence is forecasted to triple by 2050, and it has been reported to be one of the most costly disorders in Belgium. There is good scientific evidence that the cognitive impairments associated with the development of dementia can be lessened or even reversed thanks to the plasticity of the brain (rewiring). Recent research has shown that physical activity combined with performing cognitively challenging tasks is a very potent way to induce this rewiring of the brain, which can enable people to improve their cognitive functions. Yet, so far, these studies are mainly limited to controlled laboratory conditions. The investigators developed a real-life cognitively enriched walking program, with input from experts and end-users. In this study, the investigators will examine the added value of enriching physical activity (walking) with cognitive exercises in improving cognition of older adults by conducting a six-month community-based randomized controlled trial. The investigators will also examine the longer term effectiveness in a follow-up measurement visit six months after the program. The investigators will focus on the following outcomes: cognitive functioning (i.e., objective, subjective and cognitive activity), psychosocial wellbeing (i.e., loneliness, social support, depressive symptomatology, positive wellbeing and expectations regarding aging), physical activity (i.e. both objective and subjective) and general health.
The overall aim of this pilot study is to investigate the development of magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) markers after cerebral amyloid angiopathy (CAA)-related and hypertensive arteriopathy (HA)-related intracerebral hemorrhage (ICH) in relation to cognitive decline. The results from this pilot trial will be used to design a larger cohort study to investigate underlying mechanisms of cognitive decline after ICH. The study population consists of 32 patients; 16 patients with CAA-related ICH and 16 patients with HA-related ICH who are 55 years or older. Data will be collected at four measuring points: at baseline (during hospital admission for the ICH or at the outpatients clinic within one month of presentation with an acute ICH), after three months, after six months and after 12 months. Premorbid cognitive functioning will be assessed with the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) to select participants without pre-existing cognitive impairment.
The purpose of this study is to collect normative test values and demographic information for normative and referential data for a rapid, portable, computerized neurocognitive testing device from healthy adults 50 and older.
Loss of cognitive function after major surgery is a significant risk in older people. It can occur acutely in the days after surgery as delirium or in months to years later as a persistent reduction in brain function termed neurocognitive decline. Together these conditions are called post operative cognitive dysfunction (POCD). They can be acutely distressing for patients and are associated with other problems after surgery. The causes of post operative cognitive dysfunction are poorly understood. Studies have been limited by a lack of biomarkers to predict which patients are at high risk of developing POCD. Research suggests silent strokes occurring during surgery and different sensitivities to anaesthetic medicines are associated with POCD. The project consists of a feasibility study to investigate markers that might predict people over 65 years old getting POCD. The first biomarker is a non-invasive monitor of anaesthetics effects on brain function called electroencephalography (EEG): The investigators will identify which EEG patterns predict delirium within five days surgery. The second set of biomarkers are two blood tests of proteins that increase after strokes: these are neurofilament light chains and tau proteins. The investigators will establish if these can be used to predict having POCD up to one year after surgery and long term cognitive impairment up to 5 years after surgery.
The present study aims to establish a non-pharmacological alternative in alleviating cognitive deterioration derived from undergoing chemotherapy treatment. Thus, the effectiveness of a personalized and computerized cognitive stimulation program in breast cancer survivors is assessed.
