Filter by: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.
This research will establish and continuously improve the FAD research network in conjunction with multi-center institutions nationwide. By collecting information on the family's demography, genetics, neuropsychology, neuroimaging, biomarkers and other information, we can understand the current FAD population in China, clarify the genetic characteristics, pathogenesis, disease characteristics and diagnosis and treatment status of AD in China; which will lay the foundation for ameliorating clinical diagnosis and treatment, establishing a Chinese FAD clinical database and an international cooperative research platform. 1. To set up a multi-center, nationwide FAD research network and database platform in China 2. To clarify the epidemiological characteristics of FAD in China. 3. To clarify the genetic characteristics of FAD in China. 4. To clarify the clinical characteristics and disease development laws of FAD. 5. To discover and verify the early diagnosis biomarkers of AD. 6. To establish a genetic counseling model.
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 etiology of Alzheimer's disease (AD), the most common type of dementia, remains largely undefined and the early diagnostic and effective treatments are still not available. In addition to the neuropathological hallmarks, cerebrovascular dysfunction has been identified as an important component of AD. Using the experimental models, we showed that cerebrovascular reactivity (CVR), the ability of cerebral vessels to dilate or constrict in response to stimuli, is impaired very early in AD. We designed this trial to compare CVR to carbon dioxide (CVR CO2) in AD patients and in persons with subjective cognitive impairment (SCI), the cognitively healthy individuals which began to worry about worsening their memory, and to correlate CVR CO2 with AD markers in cerebrospinal fluid and the blood markers of endothelial function. We hypothesize that CVR represents a potential diagnostic/prognostic marker and an attractive target for the development of new therapeutics in AD.
The LUCINDA Trial is a three-site, phase II, randomized, double-blind, placebo-controlled study of leuprolide acetate (Eligard) in women with Mild Cognitive Impairment or Alzheimer's Disease taking a stable dose of a cholinesterase inhibitor medication like donepezil. Its objective is to assess the efficacy of a 48-week regimen of leuprolide (22.5 mg per 12 weeks) compared to placebo on cognitive function, global function and plasma and neuroimaging biomarkers.
The purpose of this study is to collect samples from patients with Early-Onset Alzheimer's disease (AD) and their immediate family members for molecular analysis. Samples will be studied in order to understand how molecular changes in the body are related to the development of the disease. Researchers will study your DNA and RNA in order to help doctors diagnose, treat, and monitor people at risk of developing Early-Onset AD in the future.
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
Today, the Alzheimer's disease (AD) diagnosis is founded not only on clinical criteria but also on complementary examinations to confirm a physiopathological process of AD. In complex cases, lumbar punction could be necessary in order to measure Aβ peptides and Total and phosphorylated Tau but new biomarkers could be useful. The main objective of this project is to conserve these cerebrospinal fluids, collected in usual practice in order to validate new biomarkers for diagnosis, prognosis or therapeutic following of Alzheimer's disease and other dementia.
