Filter by:At present, many literatures have confirmed that the Mediterranean diet has the effect of delaying cognitive degeneration in patients with mild cognitive impairment, and can also slow down the speed of brain atrophy. In addition to the highly respected Mediterranean diet every year, several years of foreign research have found The maintenance of oral hygiene also has a significant relationship with the decline of cognitive function. The intervention of "oral hygiene" is a new intervention method that has started in recent years. Oral health will affect the overall health status, physical function, diet and nutritional status of the elderly. In particular, older adults with poor oral health are more likely to suffer from mild cognitive impairment. The relationship between oral health and nutrition and overall health is inseparable. If the concept of healthy eating (Mediterranean diet) recognized by the public is used and oral health education is involved at the same time. To allow patients with mild cognitive impairment to maintain oral health care in daily life, and to increase the knowledge of the Mediterranean diet and try to follow the rules of the Mediterranean diet, whether there is a more significant impact on these patients.
This study investigates the neural mechanisms of cognitive function decline, cognitive assessment methods for subjects with mild cognitive dysfunction (Mild cognitive impairment, MCI, or cognitive decline milder than MCI), and the approaches used to improve and restore cognitive function.
This study is to evaluate whether the consumption of probiotics can improve the symptoms of patients with mild cognitive impairment; also evaluate the effects of probiotics on patients' blood, oxidation and stress related indicators.
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.
Alzheimer disease (AD) is a dementing illness characterized by progressive neuronal degeneration, gliosis, and the accumulation of intracellular inclusions and extracellular deposits of amyloid in discrete regions of the basal forebrain, hippocampus, and the association cortices. Mild cognitive impairment (MCI) refers to individuals with cognitive impairment (often memory loss) that fails to meet clinical criteria for AD or another dementing illness.
Because of the lengthening of life expectancy, more and more people are concerned with the effects of aging on their mental faculties (e.g., memory decline) and with the possibility of getting Alzheimer's Disease (AD) or other forms of dementia. This increasing awareness of AD has already resulted in a growing demand for neuropsychological testing. AD's research also emphasizes the need for early screening to improve the prediction of the disease progression and the efficacy of any future therapy. Such a drive to screen for pre-dementia raises the challenging issue of frontline identification of individuals in the preclinical or early clinical stages of AD. Mild Cognitive Impairment (MCI) is typically considered to be the prodromal state of AD, and is therefore at the core of the drive for early screening. Moreover, Pre-MCI so called SCI (Subjective Cognitive Impairment) can precede AD for 15 years. However, many individuals diagnosed with MCI do not convert to AD, some remaining stable and others even reversing back to normal (with rates of reversion to normal varying from 4.5% to as high as 53%). This over-diagnosis bias, which has been largely overlooked, is at the core of the present project at the interface of human and life sciences. Here, we argue that an important source of overdiagnosis in the prodromal state of AD comes from negative aging stereotypes (e.g., the culturally shared beliefs that aging inescapably causes severe cognitive decline and diseases such as AD) that permeate neuropsychological screening. There is ample evidence in the laboratory that such stereotypes contribute to the differences observed in the healthy population between younger and older adults in explicit memory tasks. Additionally, three pilot (lab) studies specifically conducted for the present ANR project showed that the threat of being judged stereotypically undermines the controlled use of memory of healthy older adults and simultaneously intensifies their automatic response tendencies, resulting in impaired memory performance. The present proposal goes several steps further by examining for the first time whether aging stereotypes are powerful enough to implicitly permeate the clinical neuropsychological testing and thus inflate memory deficits in older adults judged "at risk" (based on either epidemiological criteria or memory complaints), resulting in false-positive detection of SCI and MCI. This provocative hypothesis will be tested while 1) using biomarkers of neurodegeneration to distinguish false-positives from true MCI, and 2) using biomarkers of stress to examine whether and how aging stereotypes can lead to acute physiological stress during neuropsychological testing. This innovative project has the potential to offer new recommendations to improve the diagnosis accuracy of prodromal state of AD, with positive consequences for older people's wellbeing.
Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research.
Recent studies have described the role of melatonin as a sleep regulator and as an anti- oxidative neuroprotective agent in improving sleep quality and delaying cognitive decline in Alzheimer's disease (AD). In accordance with this data, our hypothesis is that melatonin will delay the cognitive decline in Mild Cognitive Impairment (MCI) patients and reduce the conversion rate from MCI to AD.
