Filter by:Alzheimer's disease (AD) is the leading cause of dementia and its prevalence is estimated to exceed 100 million affects by 2050, becoming the main public health problem worldwide. Classically, AD has been considered a clinicopathological entity characterized by a progressive cognitive decline with early memory impairment followed by other cognitive domains, and an underlying neuropathological pattern characterized by extracellular accumulation of β-amyloid protein (Aβ) in the form of neuritic plaques, intracellular deposits of tau protein in the form of neuritic strands and neurofibrillary tangles, neuronal and synaptic loss and glial proliferation. In this context, a "probable" AD diagnosis was based on determining the presence of dementia and ruling out other potential aetiologies while a definite one required confirmation by post-mortem examination. In the last 15 to 25 years, progress in imaging and cerebrospinal fluid (CSF) biomarkers has enabled a change of the AD conceptualization from a clinical-pathological entity to a clinical-biological one. These new diagnostic criteria also divides the course of AD into 3 stages: (1) a preclinical phase, which would include persons with positive AD biomarkers and normal cognitive performance (the subjective perception of cognitive decline [SCD] is also part of this stage); (2) a phase of mild cognitive impairment (MCI), characterized by cognitive performance lower than expected by age and educational level; and (3) a dementia phase, once cognitive deficits interfere with the activities of daily living. This new conceptualization brings the opportunity of identifying the disease in very early symptomatic pre-dementia stages or even before symptoms appear, creating a window of opportunity for dementia prevention. The lack of positive results in the different clinical trials performed to date in patients with AD dementia has redirected the focus of therapeutic strategies towards preventing the development of dementia. For this reason, a detailed characterization of risk factors is of vital importance for identifying the persons who could benefit from a possible preventive strategy, as well as the optimal moment to carry out the intervention. A recent effort by the Lancet Commission on Dementia Prevention, Intervention, and Care reported the relative risk for incident dementia of the main modifiable risk factors (low education in early life; hypertension, obesity, and hearing loss in midlife; smoking, depression, physical inactivity, social isolation, and diabetes in late life). In addition, the Framingham Heart Study has shown that age, marital status, BMI, stroke, diabetes, ischemic attacks, and cancer are independent predictors of event risk in the final multivariate model and were used to construct a risk algorithm. These set of risk factors associated with an increased risk of incident dementia can be coupled with well-known genetic risk factors such as APOE genotype and with the presence of very mild symptoms, like self-perception of cognitive decline to create individual estimates of risk for dementia, taking also into account the presence of cognitive decline or impairment. The possibility of creating individual estimates of risk of dementia implies a personalised medicine approach and results in a change from the traditional diagnostic paradigm to a new one in which people at risk are attended in order to disclose risk factor estimates and offer them personalised solutions. This paradigm shift brings important consequences. On one hand, disclosing medical information may potentially generate emotional impact, psychological burden or harm. Although current experience with both disclosing APOE-e4 genetic status and amyloid status reveals that it is safe, one still needs to understand the potential risks and benefits of disclosing risk estimates for developing dementia. On the other hand, newly designed infrastructures that are focused in the assessment and follow-up of pre-dementia patients at high risk to develop dementia are needed, since they clearly represent a distinct population from the one attending dementia clinics. These "prevention infrastructures" would offer individual risk profiling accompanied by personalised risk reduction plans including, but not limited to, primary prevention advice and secondary prevention approaches (e.g. inclusion in prevention clinical trials). With the ultimate aim of assessing and understanding the value of these "dementia prevention infrastructures", several research questions need to be beforehand addressed such as the following: - Is disclosing risk factor estimates safe from the emotional and psychological point of view? - Is there any benefits derived from the personalised plans received by subjects? - Would the creation of Dementia Prevention Clinics be cost efficient? The BBRC-DevPrev-2018 study aims at answering the questions stated above.
The main goal of the T1rho/BBRC2017 study is to assess the capability of the MRI sequences T1rho + multicomponent T2 relaxation analysis of detecting abnormal cerebral protein deposition in AD patients in comparison with an age-matched cognitively healthy control group. Both the AD and control groups will had previously undergone amyloid PET imaging to confirm/discard cerebral proteinopathy in the context of other research studies.
By doing this study, researchers hope to learn how the Mediterranean and low-fat eating patterns affect memory, brain volume, brain antioxidant status and cardio-metabolic biomarkers, such as blood pressure and blood glucose, in cognitively normal older adults. Researchers also plan to examine underlying processes relating the patterns to brain health.
Patients admitted to acute ordinary wards in a medical center in Southern Taiwan from an elder-integrated outpatient department or emergency room from January 2017 to December 2017 were included if they met the following criteria: (i) age 65 years or older, (ii) Barthel index score ≦60 and (iii) with at least one of the following geriatric syndromes: unsteady gait or easy-to-fall ( falls ≧ 2 in last 1 year), malnutrition with Mini Nutritional Assessment-Short Form screening score < 12, urinary incontinence, pressure sores, dementia, delirium, depression, polypharmacy (≧8 medications), and excessive utilization of healthcare facilities (admission≧2, visit Emergency≧2, or visit outpatient department≧12 in one month). Patients were excluded if they were in a vegetative state, under palliative care or terminally ill and suffering from acute illness needing to be transferred to or cared for in the Intensive Care Unit. Human participant approval was obtained from the Chang Gung Medical Foundation Institutional Review Board before data collection. Participants were recruited from the ordinary wards by research assistants who screened the admission list every morning if they met the inclusion criteria. Then, the detail of the research was explained to the patients and families. They were allowed to choose to be in the control group or the intervention group. After the participants and or family agreed, informed consent was signed. For those who were cognitively impaired or suffered from dementia, informed consent was signed by their relative or partner. For the intervention group, a geriatric physician was consulted and recommendations were made by the geriatric consultant after a complete geriatric assessment. Besides the geriatric physician, the investigator's multidisciplinary team included a social worker, nutritionist and physical therapist. In the control group, the participants only received routine hospital care and no geriatric physician was consulted.
This Phase I clinical study is a randomized, double-blind, placebo-controlled, parallel-design study to thoroughly assess the safety profile and PK properties of J147 in healthy subjects. The study will include single ascending dose (SAD) in healthy young and elderly subjects.
In the next years a number of phase 2-3 trials which utilize experimental drugs possibly disease modifying for Alzheimer Dementia will reach their conclusion. This dense clinical trials activity has triggered a fundamental question both from Patients and Scientific Communities and Health Authorities/Insurances: on which basis will the new drugs -if effective-be distributed to patients or at-risk population? This question mainly deals with the "MCI prodromal to AD"condition since the MCI population actually includes about 50% of those who will progress to AD (the real "prodromic to AD" MCI form) while the remaining 50% will never convert to AD. The INTERCEPTOR project is focused on the prodromic AD condition (IWG2) or the MCI condition (NIA-AA) which form the neuropsychological point of view and is characterized by means of: cognitive questionnaires, screening test (MMSE), extended neuropsychological evaluation. The study is an observational, longitudinal cohort one, in which the baseline clinical and biomarkers characteristics of the enrolled MCI subjects at baseline will be compared for those classified as "AD converters" after 3.0 years of follow-up with respect to those "non-converters". MCI subjects who will convert to other forms of dementia will be examined separately. It will be considered the conversion to Alzheimer's disease within 3.0 years after diagnosis of MCI, together with the assessment of those who remain in a stable condition and those who have a reversion to normal cognitive profile. People with MCI who convert to other forms of dementia will be considered separately. The biomarker or a set of biomarkers that can predict the conversion to Alzheimer's disease with higher accuracy will be evaluated.
This Phase II, multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the clinical efficacy, safety, pharmacokinetics, and pharmacodynamics of semorinemab in patients with moderate AD. The study consists of a screening period, a double-blind treatment period, an optional open-label extension (OLE) period, and a safety follow-up period. There may be up to two study cohorts.
This study aims to develop and evaluate in-home assistive technology that is designed to alleviate anxiety, burden, and loneliness in spousal and familial caregivers of individuals with Alzheimer's disease and frontotemporal dementia.
Until now there is no medical treatment and/or intervention that can slow, stop or reverse the underlying neurodegenerative of Alzheimer's disease (AD). The goal of this study is to demonstrate "Oleocanthal rich-extra-virgin olive oil (EVOO) consumption stops or delay mild cognitive impairment conversion to AD by restoring the blood-brain barrier (BBB) function in humans". Specific Aims: 1. Evaluate effect of EVOO on the brain function by functional MRI (fMRI) imaging, and BBB function by dynamic contrast-enhanced MRI (DCE-MRI). 2. Evaluate effect of EVOO on cognitive function and on selected biomarkers
This is a randomized, double-blind, placebo-controlled study that assessed the efficacy, safety, and tolerability of 2 dose levels of COR388 in subjects with a clinical diagnosis of mild to moderate Alzheimer's disease (AD) dementia.
