The Georgetown University Memory Disorders Program, part of the Department of Neurology, is conducting pilot studies of the feasibility of various diagnostic tests for Alzheimer's disease, mild cognitive impairment and other neurodegenerative diseases. Further, this study is assessing longitudinal changes in biological, lifestyle, and cognitive assessment collection. The primary goal of this study is to examine the feasibility of biochemical assays, genetic testing, and cognitive and lifestyle assessments in the ante-mortem diagnosis of Alzheimer's disease, mild cognitive impairment and other neurodegenerative diseases. This research involves genetic and cognitive status testing but the findings will not be shared with research subjects. This will be accomplished ex vivo using blood, and/or cerebrospinal fluid (CSF) specimens from patients with a diagnosis of probable Alzheimer's disease, mild cognitive impairment, or other neurodegenerative diseases and from normal controls.
The Alzheimer's disease (MY) is a major problem of public health. The French National Database Alzheimer ( BNA) registers(records) all the medical acts made by units of memory(report) and of independent specialists in France. In 2008, the national Plan Alzheimer 2008 - 2012 had for objective to strengthen the search(research) on the Alzheimer's disease (MY) and for related disorders(confusions), to promote an early diagnosis and to improve at the same time the management of the patients and to support careers(quarries). A specific part(party) of this plan gave rise to the creation of the French national database Alzheimer ( BNA) to supply epidemiological data as well as indicators of activity. Since 2009 The information collected(taken in) in the BNA consists of a set(group) limited by data (CIMA of information minimum Corpus Alzheimer) concerning the demographic, clinical and diagnostic data defined by national consensus. The number of variables is limited to facilitate and to improve the participation in this national database. The participants are the Centers Report (CM)((LECTURE)) and Center Memory(Report) of Resources and Search(Research) (CMRR) and independent specialists. In 2015 more than 500 Centers send CIMA to the BNA. The plan Disease Neurodegenerative 2014 - 2019 wishes to pursue and to amplify the BNA.
The overall purpose of this project is to develop effective dysphagia rehabilitative interventions for patients with Alzheimer's Disease and related dementias at risk for pneumonia development.
Alzheimer's disease (AD) and Vascular dementia (VaD) have become common diseases in the elderly. The burden of dementia is rising in China, with major medical, social and economic impacts. To address this important public health problem, cohort study on elderly cognitive disorders should be carry out. The methods of early prevention, early diagnosis and early treatment the cognitive disorders in elderly should be found to reduce the burden of the social and economic issue due to dementia. At present, the international corresponding guidelines have taken gene and brain imaging biomarkers as important indicators of dementia pathogenesis research, accurate diagnosis and targeted intervention. Based on the above understanding, the study carry out the population cohort study based on accurate diagnosis and construct the high standard information and sample bank. The study will establish the standard and quality system of geriatric cognitive disorders cohort study (unified standards and norms). The study will integrate the standard biological samples stratified acquisition function module (homogeneity and precision) of elderly cognitive disorders, and complete the construction of biological samples bank and clinical diagnosis and treatment information database. The study will apply and develop brain structural and pathological imaging technology to support precision diagnosis of senile cognitive disorders. The study will evaluate whether peripheral nerve degeneration can predict central nervous system degeneration based on the large cohort of elderly study. In addition, The study will make an effective supplement the sample bank construction of Shanghai Mental Health Center.
Due to the demographical development, age-related diseases will drastically increase over the next decades. To face this healthcare challenge, early and accurate identification of cognitive impairment is crucial. The assessment of neurocognitive functioning ideally requires a tool that is short, easy to administer and interpret, and has high diagnostic accuracy. In this context, the use of computerized test batteries is receiving increasing attention. Compared to paper-pencil tests, computerized test batteries have many advantages. The possibility to measure reaction times may provide additional information. Moreover, test questions are always presented the exact same way, examiner-related bias is eliminated, and results are available immediately after examination. Due to the ability to adjust the level of difficulty to the performance of the individual, floor and ceiling effects may be minimized. Additionally, costs are reduced, and fewer materials and less trained personnel are required. Finally, big data approaches and the use of machine learning algorithms are becoming more popular in the field of clinical diagnostics, and computerized cognitive test batteries may facilitate future data collection to this aim. In 2014, we developed a self-administered tablet computer program for the iPad (CogCheck) to assess preoperative cognitive functioning in surgery patients. The cognitive tests used in the CogCheck application are identical or similar to the paper-and-pencil tests that are currently used in dementia diagnostics. Replacing some of the paper-and-pencil tests by a computerized test battery may facilitate the routine neuropsychological examinations. Thus, we aim to investigate the diagnostic accuracy and user-friendliness of CogCheck when applied in a cognitively impaired patient sample. In a first step, the diagnostic properties of CogCheck will be examined by differentiating between healthy controls and patients with mild or major neurocognitive disorder (NCD) predominantly due to Alzheimer's disease (AD). Data from healthy controls have been collected (EKNZ Req-2016-00393) in a previous normative study of CogCheck. Thus a further aim is to investigate the user-friendliness of CogCheck in patients with mild or major NCD predominantly due to AD. The primary aim of our study is to investigate the diagnostic accuracy of CogCheck for patients with mild or major NCD predominantly due to AD in a German-speaking population. Secondary aims are: (1) to examine the user-friendliness of CogCheck in patients with mild or major NCD predominantly due to AD, (2) to compare the results between cognitively healthy individuals (EKNZ Req-2016-00393) and patients with mild or major NCD predominantly due to AD on each of the CogCheck subtest, (3) to establish an algorithm with the CogCheck subtests that optimally distinguishes between cognitively healthy controls (EKNZ Req-2016-00393) and patients with mild or major NCD predominantly due to AD, (4) to compare the diagnostic properties of CogCheck with the ones of the currently used paper-pencil tests.
The goal of this study is to characterize biophysiolgoical signals as a comprehensive profile of the nervous systems in order to understand interactions between the brain and body, while an individual performs naturalistic behaviors (ex. walking, pointing) and while breathing at a slow controlled pace. The investigators aim to study these interactions among a variety of populations, from healthy individuals to those with disorders such as Autism Spectrum Disorder(s), including those who may also have an ADHD (Attention-deficit/hyperactivity disorder) diagnosis, Asperger's Syndrome, Alzheimer's Disease, and/or Fragile X syndrome
The purpose of this study is to evaluate the safety and efficacy of the ExAblate Model 4000 Type 2.0 System as a tool to disrupt the blood-brain barrier (BBB) in patients with probable Alzheimer's Disease (AD).
Mild cognitive impairment and Alzheimer's disease are conditions that involve memory difficulties. Transcranial direct current stimulation is a type of brain stimulation. It may help improve these memory difficulties. However, it works better on active brain areas. This study looks at if combining exercise and applying current to important parts of the brain can help improve memory in people with Mild Cognitive Impairment or Alzheimer's disease.
In this study, the investigators will be examining the effects of the deep repetitive transcranial magnetic stimulation (rTMS) using the H1 coil in patients over the age of 60 diagnosed with mild to early-moderate Alzheimer's disease (AD) or mild cognitive impairment (MCI) and comorbid Major Depressive Disorder (MDD) who have been unable to tolerate or failed to respond to antidepressant medications. The coil was designed to stimulate deeper regions of the left dorsolateral prefrontal cortex (DLPFC). Based on prior research, the investigators propose that active stimulation with the H1 coil for 4 weeks may result in significant remission rates and will be tolerable and safe.
