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.
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
This is a qualitative study that will seek to gain further understanding of the support needs of family carers to people living with symptoms of dementia up to the end of life. Family carers are friends, family members or neighbours who provide informal unpaid care to someone with symptoms of dementia. The experience of providing this care may result in family carers developing unmet needs that impact adversely on their total wellbeing. This research is potentially beneficial because little is known about the specific physical, psychological, spiritual and social needs family carers to people dying with dementia may develop. It is a priority of the UK government and the NHS to better support family carers. The government published guidelines calling on healthcare professionals to assess and address carer needs, but the evidence base for family carers to people with symptoms of dementia is limited. Findings from this study could guide healthcare professionals when they conduct clinical assessments of carer needs. Each participant to this study will be invited to attend a semi-structured interview at a venue of their choice where they will talk about their experiences of providing care. Participants must have provided informal, unpaid care to a friend, neighbour or family member with symptoms of dementia at home, including within the last twelve months of that person's life. This is a retrospective study so only former family carers will be eligible to participate. Participants must also be over the age of eighteen, be able to communicate in English and have capacity to give informed consent. This research study is being funded by the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) as part of their Research Capacity in Dementia Care Pilot Programme, which is exploring issues relating to dementia care provision.
Residents' escapes occur even if most of the nursing homes (NH) have set up specific devices to prevent from this risk. Therefore, the need to develop and validate a specific tool to assess the risk of escaping was obvious to the working group, aim at emphasizing patient centered-care by the nurses' staff and help to develop personalized devices. Aim of the study: develop and validate a specific tool to score the risk of escaping in NH residents Study design: Observational prospective multicentered cohort study Nursing homes volunteer to participate Location: Provence Alpes Cotes d'Azur Region ( South East of France) Population: 4050 NH residents. Duration: two years, each resident included is followed up for one year Measures: Nursing homes characteristics, residents characteristics ( social and from medical record); Escape Scale (25 items with a Yes/no answer; filled up during a nurses staff meeting for each resident and every three months; 3 sub scales: resident environmental items, social items, and medical items.
Electrical activity in the brain known as "gamma" brainwaves help connect and process information throughout the brain. These gamma waves are diminished in Alzheimer's disease. New research in Alzheimer's disease mouse models shows that exposure to light flickering at the rate of 40 flashes per second or 40Hz increased gamma brainwaves and led to clearing of beta amyloid plaques in the brain, a key abnormality in Alzheimer's disease. This project will test the ability of a novel iPad App (AlzLife https://www.alz.life/) that delivers light therapy at 40 Hz combined with cognitive therapy to improve cognition, function, and quality of life in Alzheimer's disease.
The aim of this study is to establish and perfect the China Cognition and Aging Study (China COAST) cohort, to clarify the epidemiology, influencing factors, genetic characteristics, pathogenesis, disease characteristics and diagnosis and treatment status of dementia and its subtypes in China. It is of great significance to establish a relatively comprehensive national database of cognitive disorders, improve the clinical diagnosis and treatment level of cognitive disorders, and formulate prevention and treatment strategies for dementia. The primary aims of China COAST are as follows: 1. To use the prospective cohort to establish a large database research platform, so as to provide comprehensive epidemiological data, clinical and neuropsychological evaluation data, biological samples, and laboratory tests and imaging data. 2. To update the prevalence and incidence rate of dementia and its subtypes every 2-3 years, and clarify the conversion pattern from normal elderly to MCI and from MCI to dementia. 3. To explore the known or unknown protective and risk factors of dementia and its major subtypes (AD, VaD, other dementia). 4. To discover new pathogenic genes and susceptible genes of dementia and its major subtypes (AD and VaD), as well as new mutation sites of known pathogenic genes. To study the genetic variation, mutation and polymorphism of PSEN1, PSEN2, APP and APOE genes in dementia patients, and to understand their distribution and roles in the pathogenesis. 5. To study the biomarkers (body fluid, genetics, imaging) with diagnostic value of MCI, AD (sporadic and familial) and VaD, to define their cut-off values, and to establish prediction models. 6. To study the diagnostic criteria of cognitive normal, MCI, dementia and their subtypes (clinical and molecular subtypes) in the cohort, and to make psychological assessment scales with high sensitivity and specificity, and in line with the characteristics of Chinese people. 7. To find potentially modifiable risk factors for dementia and to study the prevention and intervention effect of non-pharmacological treatment on APOE ε4 carriers, MCI and AD or other dementia patients，which included improvements in education, nutrition, health care, and lifestyle changes. This needs a long time follow-up. 8. To explore the relationship between dementia as well as its major subtype AD and cerebral and systemetic circulatory disorders (for example, mixed dmentia), as well as potential therapeutic strategies. 9. To carry out investigation and researches about dementia related education, improve the awareness of dementia, and strengthen the management of dementia. 10. To investigate the level of stigma and discrimination and its influencing factors in patients with Alzheimer's disease and their caregivers.
The Evidence Amyloid Study EEG (EASE) establishes an open-label, longitudinal cohort study to measure of neurological functioning during the onset and progression of cognitive decline in preclinical Alzheimer's patients using quantitative electroencephalography (qEEG) measures (P300, P50, and reaction time). Participants will be scanned using the ElectroCap (FDA Class II) and/or the WAVi headset with the WAVi EEG P300/P50 system, along with the structured clinical interviews and assessments for baseline screening or mild cognitive impairment which are standard of care.
The goal of the Alzheimer Prevention Trials (APT) Webstudy is to accelerate enrollment for Alzheimer's disease (AD) clinical trials by identifying and tracking individuals who may be at higher risk for developing AD dementia.
The investigators established the Faroese Alzheimer's Cohort with the aim to unravel genetic and environmental factors that influence the risk and/or susceptibility of Alzheimers disease (AD). It is believed the Faroese population represents a unique opportunity due to its characteristics as a geographic, environmental and genetic isolate with a homogeneous genetic background and founder effects. It has an 'engaged' population with superbly detailed genealogy going 400 years back, unfettered patient access to health care, traditionally high participation rates in research and low probability of losing subjects to follow-up, and presents a unique opportunity to more readily identify genetic and environmental factors involved in AD. The specific aims of this project are: 1. Enrolment of patients with AD, incl.1st degree family members of selected familial patients and age and gender matched control subjects. 2. Detailed genealogical investigation of patients with Alzheimer's disease 3. Identify genes influencing risk and/or susceptibility of AD in the Faroese population
