Filter by:The purpose of this study is to determine specific changes in muscle secretory profile (myokines, miRNA) in association with neurodegenerative disease progression and metabolic dysfunction. Next the investigators would like to determine the shift in the muscle secretory activity induced by regular exercise intervention, which the investigators think could be translated into the beneficial changes in clinical phenotypes, determined by neuroimaging, cognitive function tests and metabolic phenotyping.
The objective of this trial was to assess the dose-response relationship of symptomatic efficacy of talsaclidine base on ADAScog and to assess safety and tolerability
The primary objective of this Phase 2a study is to evaluate the maximal tolerated dose of ANAVEX2-73 in patients with AD in a repeated-dose administration scheme, with the secondary objectives being to explore the relationship between dosing regimen and pharmacodynamics efficacy outcomes and to evaluate the bioavailability of the oral form used and to explore the relationship of ANAVEX2-73 as add-on therapy to AD standard of care.
The study is designed to compare the effects of 4 different doses of orally administered BI 409306 to placebo in patients with Alzheimers Disease
The primary objective is to examine the efficacy of 8-weeks of a locally developed brain-computer interface based system intervention for improving attention and memory in healthy elderly and those with age related cognitive decline. We hypothesize that elderly who have completed the training program will have significant improvement in their attention and memory compared to the controls, based on the Repeatable Battery for the Assessment of Neuropsychological Status.
In its long preclinical course, AD shows a spreading pattern of specific pathology in a uniform sequence of predictable steps including brainstem nuclei in early stages. Many of these nuclei which are early involved in AD take equally part in the afferences of the Xth cranial nerve, the Vagus nerve. A method for the functional assessment of Vagus-related nuclei in the lower brainstem is the technique of somatosensory evoked potentials of the Vagus nerve (VSEP). This method targets the accessibility of early functional changes by evoked potentials on one hand and the early affection of specific brainstem nuclei comprising Vagus afferences in the course of AD on the other hand. The method of VSEP takes advantage of the transcutaneous stimulation of the auricular branch of the Vagus nerve (ABVN) which is presumed to be the only sensory part of this nerve innervating parts of the outer meatus acoustics at the tragus. This cutaneous branch was shown to gain access to Vagus afferences via brainstem regions which are affected in the course of AD. VSEP latencies in AD were shown to be significantly longer as compared to healthy controls. Yet, if VSEP really are suited for the early detection of AD is still not known. Functional near-infrared spectroscopy (fNIRS) measures changes in cerebral oxygenation by means of near-infrared light using wavelengths of 650-850 nm. The principle of fNIRS is based on the principle that regional neuronal activation of the brain leads to an increase in metabolism and oxygenation of brain tissue in that region which is accompanied by an elevated regional cerebral blood flow. In AD, there is a growing body of literature reporting deviant fNIRS activation patterns for a variety of tasks. For example, it was shown that the fNIRS activation pattern in frontal and parietal cortex areas in subjects with AD performing the line orientation paradigm is clearly different from healthy controls. Yet, if fNIRS is suited as a means of early detection of AD is not known. Therefore we aimed at testing the predictive value of VSEP and fNIRS in the early detection of AD. The hypothesis to be tested within this study states that subjects developing AD or MCI within an observation period of 6 years depict longer VSEP latencies, a different fNIRS oxygenation pattern and a lower performance in neuropsychologic rating below the level of dementia at baseline than those who remain cognitively stable.
The purpose of this study is to evaluate the safety and tolerability of allopregnanolone, a naturally occurring brain steroid, in mild cognitive impairment and early Alzheimer's disease participants. The primary goal is to determine the maximally tolerated dose.
This is a randomized clinical trial evaluating the benefits of a program that supports model care for persons with dementia and their family caregivers. Subjects were recruited from California, Nebraska and Iowa. Subjects determined to be eligible were consented and randomized into one of two groups. Two thirds of patients were enrolled into Navigated Care that provided them with assistance in meeting important benchmarks in their care, for example completion of legal and financial planning and strategies for minimizing caregiver burden. One third of patients were enrolled to a control group, entitled Survey of Care. Outcomes include quality of life, health care utilization, caregiver burden, satisfaction with care, caregiver depression, and caregiver self-efficacy.
The purpose of this study is to examine the effects of supplementing Magnesium L-Threonate in people with mild to moderate dementia. The investigators' goal is to understand whether Magnesium L-Threonate will be associated with improvement in memory and brain function.
Cognitive training has emerged as a promising method to maintain, enhance, and rehabilitate cognitive function in older adults and individuals with dementia. In recent years, such training has become particularly appealing in the clinical context, with many paradigms aimed specifically at adults experiencing various stages of cognitive decline due to Mild Cognitive Impairment, Alzheimer's disease, and vascular dementias. However, basic questions remain. For example, uncertainty persists regarding factors that influence observed improvements as well as the conditions that would maximize transfer and sustainability of training effects. The objective of this study is to evaluate factors that may maximize the benefits of computerized cognitive training in older adults.
