Active clinical trials for "Alzheimer Disease"

Examination of the correlation between the cerebral bloodflow and the clinical change under treatment with Reminyl retard® and the prediction of clinical change by measuring the cerebral bloodflow in patients with mild to moderate Alzheimer's Disease

This study will be an observational study in which patients who have been prescribed CerefolinNAC® are invited to participate in surveys regarding their experiences with CerefolinNAC®. CerefolinNAC® is a medical food indicated for the distinct nutritional requirements of individuals under treatment for early memory loss with particular emphasis for those individuals diagnosed with or at risk for neurovascular oxidative stress and/or hyperhomocysteinemia; mild to moderate cognitive impairment with or without vitamin B12 deficiency, vascular dementia or Alzheimer's disease. The purpose of this study is to increase the understanding of the role of CerefolinNAC® in managing proper neuronal function in the brain, provide patients with personalized education and support, and contribute to the overall understanding of the needs and concerns of patients being treated for early memory loss.

PBA is a neurologic condition that is estimated to impact over a million patients and their families in the United States. PBA occurs secondary to an otherwise unrelated neurologic disease or injury, and manifests as involuntary, frequent, and disruptive outbursts of crying and/or laughing. Progress has been made in better understanding this debilitating condition, but much more needs to be done. That's why a new PBA patient registry, PRISM (Pseudobulbar Affect RegIstry Series), has been initiated. The goal of PRISM is to establish the prevalence and quality of life (QOL) impact of PBA in patients with underlying neurologic conditions including Alzheimer's disease Amyotrophic lateral sclerosis Multiple sclerosis Parkinson's disease Stroke Traumatic brain injury Because this is an observational registry, it doesn't require you to intervene with any specific treatment or procedure. Your participation allows the PRISM registry to collect and analyze data from your site and also compare it to national numbers captured in the PRISM registry about PBA across all of the major at-risk neurologic populations.

The purpose of this observational study is to investigate the changes in cognitive functioning, behavior, and functional improvement in Alzheimer's disease patients treated with Galantamine who are living at home (i.e. not in permanent residential care), and to obtain information regarding usual clinical practice that can be used for communicating treatment expectations to patients and supporters.

The purpose of this study is to assess the performance of AclarusDx™, an investigational blood test detecting gene expression information, and intended to help physicians in making an Alzheimer's Disease diagnosis in patients having memory impairments.

The purpose of this study is to use brain imaging technology to examine the role of certain brain chemicals in individuals with Alzheimer's disease (AD) and in healthy volunteers. Cognitive dysfunction in people with AD is thought to arise from decreased chemical activity in specific parts of the brain. Decreases in alpha4beta2 nicotinic acetycholine receptors (nAChRs) have been found in the brains of people who died with AD; however, the status of this receptor system in living brains remains unclear. This study will use single photon emission computed tomography (SPECT) to study this receptor system in people with AD who have mild to moderate dementia and in healthy volunteers. In addition, this study will examine the relationship between cognitive dysfunction and nAChR deficits in the brains of individuals with AD. Participants with AD will have four clinic visits; healthy volunteers will have three visits. At Visit 1, participants will undergo a medical history, physical examination, and laboratory tests. Healthy volunteers will have a Mini-Mental State Examination (MMSE) cognitive function test. Participants with AD will have a MMSE and measurement of the severity of their dementia. During Visit 2, participants will undergo a magnetic resonance imaging (MRI) scan of the brain. At Visit 3, participants will undergo SPECT imaging. Only participants with AD will participate in Visit 4. During this visit, cognitive testing will be performed.

The purpose of this study is to evaluate people with mild memory problems, those with dementia, those at risk for developing Alzheimer's disease (AD), and healthy volunteers to identify markers of AD before the changes that occur with the disease begin. The origin and markers of progression for Alzheimer's disease (AD) are relatively obscure. Despite increased understanding of the underlying biology of AD, its clinical diagnosis is still made only after progressive cognitive decline; definitive diagnosis is confirmed at autopsy. This study will examine biomarker changes over time in a distinct cohort of people with an increased risk of developing AD. The study will also identify and track biological changes that occur with progressive dementia and compare those changes to the known cognitive and emotional disturbances that characterize AD. Individuals with a first-degree relative with AD will be recruited into an at-risk cohort. They will be followed and compared to a group of healthy volunteers for a minimum of 8 years.

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.

To afford urgent access to a potential-disease modifying treatment, Dr. Diana Kerwin, in partnership with CTD Holdings, the manufacturer of Trappsol (R) Cyclo(TM), will administer the product to a patient with Alzheimer's Disease who has no other disease-modifying treatment options.

The objective of the study is to highlight a modification of the composition of the intestinal microbiota associated with the diagnosis of Alzheimer's disease and its most unfavorable form, Rapid Cognitive Decline (DCR). This identification could lead to diagnostic strategies based on the analysis of the intestinal microbiome, and preventive and curative treatments, based on the modulation of intestinal microbiota
