Older adults (≥ 55 years) who do not eat enough nutritious food are at risk of malnutrition. Malnutrition can lead to frailty, hospitalization, poor quality of life, and death. SCREEN (Seniors in the Community Risk Evaluation for Eating and Nutrition) is the leading nutrition risk screening tool for cognitively well older adults living in the community. The purpose of this study is to determine if SCREEN can be used to find nutrition risk among older adults diagnosed with mild cognitive impairment or dementia (i.e., MCI-D) living in the community and persons living in retirement homes. SCREEN and other nutrition and health measures will be completed in 600 older adults (300 living in retirement homes with or without MCI-D, and 300 living with MCI-D in the community). SCREEN will be completed twice to determine reliability, and persons with MCI-D will have their results compared to those of a caregiver who completes it on their behalf. A dietitian's assessment and rating of nutrition risk will be used as the gold-standard to determine validity.
This study evaluates an educational brochure tailored to caregivers of people with Alzheimer's disease, Parkinson's disease dementia, Lewy body disease, frontotemporal dementia, and vascular disease dementia. The goal of the brochure is educating caregivers about the decreased ability to detect emotion and decreased empathy that can be seen in dementia, increasing caregiver competence in providing care, and teaching caregivers ways to manage over time that lessens burden and improves quality of life.
The aging of the United States (US) population will lead to a steep rise in Alzheimer disease (AD). There is an urgent need for novel therapies that may tackle this looming societal problem. People with Alzheimer disease have frequently evidence of vascular disease in the brain, and vascular disease can increase the risk of Alzheimer disease. Based on this finding, the investigators plan to expand the understanding of how vascular disease contributes to Alzheimer disease, hoping to identify novel target to modify the natural progression of the disease. The investigators will accomplish this goal by inviting 300 participants (with and without dementia) of the Northern Manhattan Study (NOMAS) to undergo a brain magnetic resonance imaging (MRI) and donate blood. Of the 300 participants enrolled, 60 participants will be randomly selected to undergo Aβ and tau positron emission tomography (PET) imaging. From the brain MRI, the investigators will obtain measurements of cerebrovascular disease and relate the to the risk of Alzheimer disease. With the blood, the investigators hope to identify measures of aging and inflammation that may predict changes noted in brain scan and identify people at a higher risk of dementia. The investigators will examine PET markers of inflammation and aging in the brain and how the markers relate to dementia.
Dignity is an integral part of quality of life (QoL). Older adults often face with situations that are related with the development of dementia and that might significantly affect their feeling of personal dignity. The aim of the project is to investigate the changes in the perception of personal dignity amongst older adults with dementia (OAwD) over the course of three years and to define factors that threaten their dignity. A mixed methods design (longitudinal prospective study) will be used. In the quantitative part, a battery of Czech questionnaires will be used, and a translation and validation of a Czech version of the ACE-III will be carried out. The qualitative part will include in-depth interviews (narrative and semi-structured). The sample will comprise of OAwD living in home setting. Knowledge of the changes in the perception of personal dignity and related factors may aid the healthcare staff in choosing interventions that support and preserve dignity of OAwD as a significant part of their QoL. The project is a follow-up of a previous project No. 16-28628A.
The purpose of this open label study is to evaluate longer term tolerability and early efficacy of transcranial ultrasound in the treatment of patients with mild cognitive impairment or dementia.
Caregivers of home-dwelling people with Alzheimer's Disease and related dementias (ADRD) are one of the most rapidly growing populations in the United States. Among ADRD caregivers with unmet health-related social needs, this study aims to evaluate the effects of the CRx-D intervention versus usual care on caregiver self-efficacy.
The VOICE Of bvFTD study is a telephone interview research study about life with or at risk for behavioral variant frontotemporal dementia (bvFTD). The study aims to understand how bvFTD impacts individuals' day to day lives, how people think about themselves, and what challenges they face.
High blood pressure (present in 1 of 5 Canadian adults) increases the risk of heart attack and stroke. Blood pressure lowering pills reduce this risk - but perhaps not optimally. A Spanish study suggests that using blood pressure pills at bedtime, instead of in the morning (when they are most commonly used), reduces death, heart attack, and stroke by more than 50%. If true, a switch to bedtime prescribing would have more impact on the health of those with high blood pressure than whether high blood pressure is treated at all. BedMed, a community-based Canadian primary care trial, is already running and looking both to validate the findings of this Spanish study and to determine whether there might be unrecognized harms of bedtime use (such as more falls and fractures as a result of lower overnight blood pressure). One very important population that is likely to be more sensitive to the effects of medications, and almost always excluded from randomized trials, are the frail elderly (such as those who are resident in nursing homes). In order to have the greatest information about the safety and effectiveness of bedtime blood pressure medications, the BedMed team is additionally conducting a similar trial to BedMed in nursing homes ("BedMed-Frail" - the subject of this trial registration) to determine whether the risks and benefits of bedtime prescribing differ in this highly understudied population. Basics of the trial: When patients are admitted to nursing homes, neither they nor their physicians are consulted about the timing of blood pressure medication. Unless explicitly stated to be otherwise, blood pressure pills are instead largely arbitrarily assigned for morning use by default. Given there is evidence that bedtime administration may be safer, the nursing homes participating in BedMed-Frail will have each hypertensive resident randomized to either continue with morning blood pressure medication use, as is their norm, or to have their facility's pharmacist gradually switch each residents blood pressure pills to bedtime. Over a period of roughly 3 years, health outcomes in these facilities will be tracked using routinely collected electronic health data to determine differences in things like hospitalization, death, or hip fractures - and at the end of the study the investigators hope to determine whether or not the recommendations for blood pressure medication timing in frail older adults should differ from those for the general population.
The study intends to measure the evolution over time of the cognitive capacity of patients undergoing cataract surgery in relation to the opaque lens removal surgery (cataract) in a population considered to be at risk of neurocognitive degeneration. Secondary objectives: • Estimate the incidence of postoperative cognitive dysfunctions and any episodes of perioperative delirium with the aim of demonstrating the safety of cataract surgery in the elderly patient in terms of cognitive functions and impact on the psychological state. In the context of the study a risk sub-population analysis will be carried out, evaluating the trend over time of the "endothelial cells count" parameter The elderly population remains, due to the aging of the cornea, a population "at risk" for significant alterations from the clinical point of view. During the study the endothelial cells count will be monitored, in order to be able to evaluate the safety of the cataract surgery and to be able to correctly correlate a possible deterioration in the visual acuity of patients with corneal decompensation. To evaluate the progress of the endothelial cells count in the elderly patient during the pre-intervention and post-intervention period. Since the low values of cellular media in endothelial microscopy are an element that increases the risk of complications during cataract surgery, the study wants to assess how waiting times between filter visits and cataract surgery can cause an elderly patient worsening of this parameter even in a few months. The trend of the same parameter will be monitored even after the intervention since in case of decrease, the low endothelial count could cause an alteration of visual acuity and therefore a minor improvement in cognitive performance. The research will be set as a longitudinal observational study where will be compared in each patient the parameters analyzed in the 6 months prior to cataract surgery and in the 3 months following the operation itself. Patients will be enrolled during the first cataract filter visit, will be submitted to simple questions and their clinical data will be collected. Subsequently, before and after three months of surgery repeated cognitive testing and the control normally performed instrumental tests during follow-up. A clinical follow-up will be provided, during normal follow-up visits at 20 days and 6 months after the patient's surgery: the following information will be collected during these visits - BCVA (visual acuity) - endothelial cells microscopy - OCT macula and optic nerve - Catquest 9SF; - Barthel Index; - Six Item Cognitive Test - Confusion Assessment Method (CAM): this exam will be performed within 24 hours of post-surgery and 20 days after surgery. It is important to underline that the cognitive tests proposed to patients consist of simple questions that do not depend on the visual ability of the subject.
