The Effect of the Glycemic Load of Meals on the Cognition and Mood of Older Adults
DementiaA lower rather than a higher glycemic load (GL) meal has been shown to benefit cognition and mood, however, the data in older adults and those most prone to cognitive dysfunction, is limited and conflicting. One explanation is that the GL of a meal may interact with a person's pre-existing glucose tolerance (GT). As older adults have a higher incidence of glucose tolerance and are more likely to experience memory problems the present study considers the interaction between the GL of meal in those with better or poorer GT. The population studied will not have a history of diabetes or dementia. A battery of cognitive tests will be administered after meals sweetened with one of three sugars known to vary in the rate that they release glucose into the blood stream.
A Psychosocial Intervention for Bereaved Spousal Caregivers of Persons With Dementia
DementiaBereavementThe purpose of this study is to evaluate the feasibility and acceptability of a writing intervention (Reclaiming Yourself), intended to facilitate bereavement for spousal caregivers whose partners died with dementia.
Advanced Dementia and End-of-life
Advanced DementiaPalliative and hospice care in advanced dementia: experiences of care givers and benefit of a brochure serving as a decision-making aid Aims: Designing a brochure serving as an information tool and decision-making aid used to answer questions concerning palliative and hospice care for care-givers of persons with advanced dementia. The brochure shall demonstrate the possibilities and offerings of palliative and hospice care and shall serve to inform about the advanced stages of dementia, the legal basic principles in decision making and ethical problems, treatment options and (palliative) treatment goals. Survey of the palliative, palliative medical and hospice care of persons with advanced dementia in ambulatory settings, as well as in residential geriatric care and the experiences of the care-givers. By examining persons with dementia and inspecting the care documents and where applicable the medical files it is to be evaluated: which procedures of palliative and hospice care are practically implemented in ambulatory care and in residential geriatric care, which symptoms the persons with dementia suffer from and how those symptoms are (or are not) treated, to what extend caregivers are informed about relevant aspects how caregivers assess care and which problems, needs and requests exist. Piloting phase for the brochure. To test the comprehensibility and the acceptance of the brochure a study is planned. The caregivers are asked for their opinion whether the brochure is helpful. It is recorded if the reading of the brochure gets the caregivers to engage actively in the participative decision making process.
Hand Grasping Techniques on Eliciting the Grasp Reflex in Patients With Dementia
DementiaIn this study, the investigators will determine the difference between the two techniques used to elicit the grasp response in patients with frontal lobe dysfunction, primarily in dementia patients versus control patients.
Aligning Patient Preferences: a Role Offering Alzheimer's Patients, Caregivers, and Healthcare Providers...
Alzheimer DiseaseDementiaNursing home (NH) patients with Alzheimer's disease and related dementias often receive unwanted, burdensome treatments such as hospitalization. Advance care planning (ACP) is a key strategy to support patients and family-caregivers in making informed decisions and ensuring treatment preferences are proactively known and honored. The ACP Specialist Program will improve care and reduce unwanted, burdensome hospitalizations through improved ACP procedures, standardized staff education on ACP, and systematic ACP facilitation delivered by existing NH staff.
Ageing Gut Brain Interactions
Dementia AlzheimersThis research project will address a desperate need for evidence on how diet could be used to treat and improve symptoms of Alzheimer's disease (AD). It has been estimated that 36 million people have dementia worldwide, and in older people Alzheimer's disease accounts for 60-70% of all dementia. Research supports the hypothesis that modifiable lifestyle-related factors are associated with cognitive decline, which opens new avenues for prevention or modification of disease. The concept that inspires this proposal 'Ageing-Gut-Brain Interactions study' is that the gut microbiota impact upon the gut-brain axis and thereby on behaviour, including challenging behaviours often associated with dementia. In the absence of available cures for Alzheimer's disease, diet is an important modifiable component but knowledge about the role of diet in clinical symptoms of dementia is currently very limited. A recent study from Ireland from the European Union funded Nu-Age cohort reported that the gut microbiota profile in the elderly was different between community-living and institutionalized individuals, with specific microbiome profiles correlating with frailty and poor health. Changes in dietary composition and diversity were considered the main drivers of the shifts in gut bacteria profile. In this multi-disciplinary research study, the investigators will assess the gut microbiota composition in people with Alzheimer's dementia with and without challenging behaviours; test the feasibility of recruitment; and provide initial data to support a future grant application involving a dietary intervention study in patients with Alzheimer's disease. The investigators will test the hypothesis that the gut-brain axis promotes behavioural changes in Alzheimer's dementia and is responsive to changes in gut microbiota profile, by comparing the gut microbiota profile between three participant groups (1) Alzheimer's dementia with challenging behaviour, (2) Alzheimer's dementia without challenging behaviour, and (3) a control group of healthy age-matched elderly. The investigators will also carry out a survey of care homes to assess willingness to participate in a future dietary supplementation study.
Genetic Evaluation for Medication Selection (GEMS) Study
DementiaPsychiatric Disorders Mood1 moreInvestigators propose to determine whether knowing details about how a person's genes affect the way medicines work in the brain and body will help doctors pick more effective or safer medicine for that person. Target symptoms are restlessness, agitation, depression and related problems common in people with memory loss and dementia.
Brain Vascular Disease in Aging and Dementia
Alzheimer DiseaseWhite Matter Hyperintensities2 moreThis study examines the factors that may drive the relationship between vascular disease and Alzheimer's Disease (AD) in a large, longitudinal, multi-ethnic community-based cohort study of older adults in northern Manhattan, New York. In past research, the investigators demonstrated that accumulation of brain vascular disease is associated with risk for development of AD. The study now extends the research to examine how brain vascular disease and AD interact. In this pilot study, the investigators will obtain positron emission tomography (PET) scans to measure amyloid (one of the protein pathological markers of AD) from participants in an ongoing community-based study of aging and dementia (WHICAP). The study will include subjects who are already enrolled in the parent project. Further, this study will enroll both subjects who have never been evaluated with PET scans and those who received a previous baseline PET scan. The study plans to obtain approximately 30 repeat amyloid PET scans and 20 baseline PET scans. The investigators will also conduct transcranial Doppler studies to measure blood flow in the participants with amyloid PET scans. The potential benefits to society should be considerable if this study reveals new information about risk factors for or contributions to AD.
Impact of Anticoagulation Therapy on the Cognitive Decline and Dementia in Patients With Non-Valvular...
DementiaCognition Disorders1 morePatients will be screened at Intermountain Medical Center and at Intermountain-affiliated anticoagulation clinics in the Salt Lake City region. Patients with non-valvular atrial fibrillation will be considered for study. After written informed consent is obtained, subjects who meet eligibility criteria will be randomized 1:1 to 2 treatment arms: Group 1: Dabigatran etexilate (150 mg BID if CrCL > 30 mL/min, or 75 mg BID if CrCL > 15 to 30 mL/min or per USPI; and Group 2: Warfarin (Dose-adjusted (INR 2.0 - 3.0). Assessment of kidney function every 6 months will be done for Group 1. Standard warfarin follow-up and education, based upon system criteria, will be done for Group 2. All subjects will be followed for 24 months, and will be assessed at 1-week, then 3-, 6-, 12-, 18- and 24-months post-anticoagulation visits as well as other visits deem necessary for clinical care. All subjects will undergo protocol-specified laboratory tests and will complete 6 standard, validated questionnaires at each follow-up visit following the week 1 visit, except at the 3-month visit when only one questionnaire will be administered. To determine brain volume and characteristic changes representative of micro-bleeding, the first 10 subjects in each treatment group who are willing and able to undergo the procedure will participate in a MRI sub-study. The cranial MRI will be done at baseline and at 24-months post-anticoagulation on this sub-group.
RHAPSODY-plus: Online Counseling for Family Caregivers of Patients With Young Onset Dementia
Early Onset Alzheimer DiseaseFrontotemporal DementiaThe RHAPSODY-plus project consists of two parts. In a first step carers of people with young onset dementia (YOD; onset before the age of 65) have the opportunity to use the RHAPSODY online program (Kurz et al., 2016) to inform themselves about different topics on young onset dementia. In a second step the participants will receive two individual counseling sessions via MEET (online videoconferencing) with a social worker and a psychologist. Goal is to investigate whether these counseling sessions have an additional benefit.
