Filter by:multi-center, randomized, double-blind, parallel-group,placebo-controlled study to evaluate the safety and tolerability, efficacy, and PK of 60 mg AD-35 administered QD during 6 months of double-blind treatment followed by a second 6 months of open-label treatment to subjects with mild to moderate AD.
Alzheimer disease (AD) is a neurodegenerative disorder with a poorly understood pathology. It is an irreversible progressive brain disease that slowly deteriorates memory, thinking and behavior. It affects the elderly population and is also hereditary. The incidence doubles with every decade after sixty with no signs of leveling off. More than 35 million people Worldwide, including 5.5 million living in the United States, suffer from AD. As the United States population ages, it is expected that the number of people with AD will increase, reaching 13.2 to 16.0 million by the year 2050. The cost of care for patients with AD in the United States is expected to rise as well, from $172 billion a year in 2010 to a trillion dollars a year by 2050. Although the exact etiopathology is not known there are several lines of evidence that suggest that metabolic and inflammatory features are important. It also has been known for many years that the Blood Brain Barrier (BBB) of Alzheimer's patients allow more harmful particles to cross into the brain than the BBBs of those without the disease do. It's known that this barrier, which is regulating transfer of molecules between the brain and blood, and vice versa blood and brain, can become leaky and dysfunctional (in particular capillaries dysfunction) and lead to subsequent problems likely contributing to onset and progression of dementia. This protocol will explore several of the most promising putative factors that cause AD.
Neurodegenerative diseases such as Mild Cognitive Impairment, Alzheimer's, and dementia affect millions of Americans. Although these diseases are heavily researched, there is very little research examining the impact of attenuated carotid artery endothelial function and cerebrovascular blood flow on cognitive function. This is surprising, as cerebrovascular oxygenation has been shown to be strongly associated with reduced cognitive function and the pathogenesis of neurodegenerative diseases. For example, hypertension, diabetes, and high cholesterol have been shown to increase the risk of Alzheimers related dementia. Therefore, the purpose of this proposed study will be to examine the effects of MitoQ supplementation on carotid artery vasodilatory function and cerebrovascular blood flow in those suffering from Mild Cognitive Impairment (MCI). MitoQ is a mitochondria-targeting antioxidant that can improve nitric oxide production in the blood vessel, which should improve endothelial function, and thus cerebrovascular blood flow.
This study aims to determine factors related to diagnosis delay for patients with young onset dementia (first symptoms before 60 years old) who live in North of France.
This study attempts to identify two types of AD by using clinical and cognitive tasks and brain imaging. The subtypes of AD are separated into a "typical" group (memory loss) and a "variant" group (language, visuospatial, and other cognitive difficulties). Performance on the clinical tasks and brain imaging will be compared among the young-onset Alzheimer's disease group, a late-onset Alzheimer's disease group, and a control group.
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).
This is a neuroimaging study designed to learn more about amyloid and tau burden in the brain of patients with typical and atypical Alzheimer's Disease and how burden may change over a one year period.
Current diagnosis of Alzheimer disease is made by clinical, neuropsychological, and neuroimaging assessments. Routine structural neuroimaging evaluation is based on nonspecific features, such as atrophy, which is a late feature in the progression of the disease. Therefore, developing new approaches for early and specific recognition of Alzheimer disease at the prodromal stages is of crucial importance. In the present study the investigators would like to examine if combined treatment with TMS and cognitive training (CoTra) for several weeks can produce a sustained improvement in cognitive and behavioral symptomatology of Alzheimer's disease (AD) patients. A number of in vivo neuroimaging techniques, which can be used to reliably and noninvasively assess aspects of neuroanatomy, chemistry, physiology, and pathology, hold promise.
