Filter by:The purpose of this project is to determine whether obstructive sleep apnea (OSA) treatment with positive airway pressure therapy (CPAP) can delay the progression of cognitive impairment in patients with amnestic Mild Cognitive Impairment (MCI) as measured by cognitive testing, and brain magnetic resonance imaging (MRI) scans. Study participants will be assessed at baseline, six-month (cognitive tests only) and one-year follow-up.
Loss of slow wave sleep (SWS) is common in mild cognitive impairment (MCI) and Alzheimer's disease, and is thought to worsen thinking, memory and brain degeneration. Initial studies suggest that correction of sleep deterioration may slow the progression of brain damage in mild cognitive impairment, and might be able to stop the development of Alzheimer's disease. Transcranial alternating current stimulation (tACS) uses electrodes to deliver very small amounts of electricity through the brain, with direct effects on brain cell function. Transcranial electric stimulation has been demonstrated to enhance slow wave sleep and to improve memory when applied during sleep in healthy adults. The purpose of this research is to investigate tACS to modulate sleep, thinking/memory, mood, and quality of life among normal healthy adults, older adults, as well as individuals with MCI.
Behavioral interventions currently provide the most useful approach to addressing the behavioral and social needs of those with Mild Cognitive Impairment (MCI) due to Alzheimer's or other diseases. This randomized, multisite, 3-arm study will investigate the impact of computerized brain fitness vs yoga vs an active control group (wellness education) on changes in cognitive function, daily functioning and quality of life in persons with Mild Cognitive Impairment (MCI) and their partner. In addition, in vivo neuroimaging measures of plasticity during the pre- and post-intervention periods will be measured and compared between the three different treatment groups. These neuroimaging measures of plasticity will be investigated in their relationship to the cognitive outcomes within each group.
Cognitive impairment is also a major risk factor for development of dementia later in life. Findings from recent studies suggest that the there are many nutrients contained in foods that may be important in cognitive function in the elderly. This study evaluates long-term intervention with almonds and snack mix as a treatment strategy for age-related cognitive impairment which could possibly prevent the onset of dementia. The proposed study is designed as a randomized, placebo controlled trial that tests the effects of 6 month supplementation with 1.5 or 3 ounces of almonds or 3 ounces of shortbread containing coconut oil on cognitive function in older adults. Secondary outcomes include plasma biomarkers of oxidative stress and inflammation.
Participants enrolled at the Alzheimer's Disease Research Center (ADRC) at Wake Forest School of Medicine will be invited to take part in this study. The purpose of this study is to identify and measure the amount of a protein called amyloid in the brain.It is thought that the build up of amyloid may be related to the development of Alzheimer's disease.
This study plans to assess the effectiveness of performance-based functional assessments (PBFAs) and cognitive assessments in diagnosing Alzheimer's disease in Hispanic/Latino populations. The information from this study will be analyzed with data from the Rocky Mountain Alzheimer's Disease Center Bio-AD study (NCT02612376).
This study is intended to clarify the benefits to brain health and thinking processes that result from different forms of exercise. In particular, this study will investigate the possible benefits of physical exercise (such as pedaling an under-table stationary elliptical) or mental exercise (such as playing a videogame on a portable tablet), or combining these activities together (as in the iPACES™ exergame).
The purpose of this research study is to test whether nicotinamide, also known as vitamin B3 or niacinamide, taken in high doses, can reduce phosphorylation of tau (the protein that accumulates in neurofibrillary tangles) in people with Mild Cognitive Impairment or mild Alzheimer's disease (AD) dementia.
Despite the high prevalence of Alzheimer's disease (AD), its underlying mechanisms remain poorly understood. An emerging body of evidence supports disorientation as an early marker for AD-related neurodegeneration. In this study we intend to collect, coregister and analyze Positron Emission Tomography (PET) and , functional and structural magnetic resonance imaging (MRI, fMRI) data from AD-spectrum patients to establish orientation as core disturbance in AD.
Parkinson's disease (PD) has been classically regarded as a "movement disorder", so earlier work has focused on treating motor symptoms only. As PD patients now have longer life expectancy, the relatively slowly progressing cognitive deficits (compared to their motor deficits) have become one of the major challenges. Approximately 80% of PD patients eventually become demented. Therefore cognitive dysfunction is one of the most significant factors affecting the quality of life of patients with PD. While dementia in Parkinson's disease is routinely treated by cholinesterase inhibitors (e.g., donepezil and rivastigmine), their efficacy on mild cognitive impairment found in non-demented PD is questionable. Alternative approaches have been proposed including transcranial direct current stimulation (tDCS) but no consensus has been reached. This can be attributed mainly to: (1) imprecise knowledge of the underlying functional circuitry mediating this disease manifestation and (2) inter-individual variability. Here, the investigators will utilize a novel personalized network analysis approach to elucidate on the underlying mechanisms of the effect of tDCS on cognitive dysfunction in non-demented PD patients. It has been well documented that the caudate nucleus plays an important role in cognitive dysfunction found in PD. In the investigators' preliminary resting-state functional magnetic resonance imaging (fMRI) study, they have shown that the connectivity of the right caudate nucleus is correlated to cognitive status of PD patients measured by the Montreal Cognitive Assessment (MoCA). The investigators hypothesize that tDCS on the left and/or right dorsolateral prefrontal cortex may restore the functional connectivity of the right caudate nucleus which may in turn improve patients' cognitive performance.
