Active clinical trials for "Dementia"

The purpose of this study is to compare 23 mg donepezil sustained release (SR) to the currently marketed formulation of 10 mg donepezil immediate release (IR) in patients with severe Alzheimer's disease.

There are no pharmacological interventions that delay or prevent the transition of mild cognitive impairment to dementia. Several studies have shown that transcranial magnetic stimulation (TMS) could be useful in increasing cognitive traits in dementia. As TMS is performed in a clinical setting, transportation, mobility and high costs of treatment, limit the number of TMS sessions dementia patients can receive. Most of the trials do not apply more than 20 TMS sessions Here, a randomized, sham controlled, paralallel group, clinical trial will be performed in order to asess the efficacy at improving cognitive traits of a novel TMS device that uses high frequency and low intensity pulses. As the device is portable and can be used from home without clinical supervision, the stimulation will be applied two times per day for a period of 6 months.

Alzheimer's disease (AD) is characterized by neuritic plaques, neurofibrillary tangles, and neuronal cell loss. Amyloid plaques are believed to play an integral role in AD. Elevated levels of Aβ in the brain are correlated with cognitive decline. There are no approved ways to measure amyloid load in humans. Several compounds are under investigation. All of these compounds use radioactive chemical tags for positron emission tomography (PET) imaging. The most promising compound is 11C-PIB, or Pittsburgh Compound-B. This compound can be injected and a PET scan performed. This allows doctors to see the amyloid plaques in the brain, and to use this information to look at other types of dementia to see if there are differences and/or similarities in the plaques. We will recruit a total of 30 subjects, 10 from each of the following three diagnostic categories: frontotemporal dementia (FTD), Alzheimer's disease, and normal volunteers. All subjects will be given an [18F]fluorodeoxyglucose or FDG-PET scan (if they haven't had one in the past) and a PIB-PET scan. The overall objective of this project is to study the biodistribution of 11C-PIB using PET imaging in normal elderly volunteers and relevant patient groups.

Behavioural and Psychological Symptoms of Dementia (BPSD) (such as aggression, restlessness, agitation, wandering, anxiety, depression) are common to most people with dementia at some point during their illness and represent an aspect of dementia particularly difficult to manage. There is growing attention to the therapeutic effects of natural environments on people's health. Exposure to natural environments (seeing greenery, hearing outside natural sounds) has been shown to enhance wellbeing, reduce depression, anxiety and stress levels, and decrease hospital length-of-stay for inpatients. Virtual Reality (VR) is a novel technology that uses a Head Mounted Display (HMD) to generate simulated immersive experiences that elicit perceptions and behaviors similar to those in real life and can make one feel as though they are truly present in another place. Based on scientific research, previous studies, and expert consultation, we created a library of VR experiences depicting calming nature scenes designed specifically for people with dementia. The objectives of this RCT are 1) to evaluate the effects of VR-therapy on BPSD and the hospital care experience of in-patients with dementia and/or delirium admitted to an acute care hospital, 2) to determine the usability, tolerability, and safety of VR-therapy for patients with dementia and/or delirium admitted to acute care, 3) determine the effect of VR-therapy on quality of life for patients with dementia and/or delirium admitted to acute care and 4) to explore a framework for introducing non-pharmacological therapies in acute care hospitals. Our hypotheses are 1) VR-therapy helps manage BPSD (e.g. decrease anxiety, aggression, depression, violent behaviors, incidents of wandering), and may decrease the amount and/or frequency of sedatives and anti-depressant medication administered and/or the number of incidents that require restraints, and the number of falls, in people with dementia and/or delirium admitted to an acute care hospital. 2) VR-therapy will improve the quality of life for individuals with dementia and/or delirium admitted to an acute care hospital (operationalized through conducting a validated instrument to measure quality of life for people with dementia). 3) VR-therapy is safe and feasible to administer to individuals with dementia and/or delirium admitted to an acute care hospital (with assistance from their circle of care members and/or caregivers).

This pilot study examines the impact of an enhanced care transition process vs. usual care for persons with dementia admitted to a transitional unit (hospital or LTC) for management of behavioural and psychological symptoms of dementia (BPSD) with a planned discharge to long term care (LTC) facilities or other hospital units. Deficiencies in discharge processes can contribute to poor outcomes (e.g., readmissions), and there is a dearth of research on how to improve care transitions for persons with BPSD. The investigators aim to improve the care transition process for persons with dementia and BPSD utilizing an enhanced care transition process that will contain up to 6 elements: integrated behavioural care plans, videos, patient specific briefcase containing activities to reduce BPSD, in-person care transition meeting, in-person care demonstration (when possible), and follow up visits with a transition team. The ability to determine the effect of enhanced care transitions on the clinical course of patients with planned discharge to LTC or hospital may allow for improved outcomes and an overall increased efficiency of post discharge care.

This project will study intranasal (IN) insulin in Frontotemporal dementia (FTD) in 12 patients. Study Investigators aim to evaluate the feasibility of the EXAMINER cognitive battery as a cognitive outcome measure in FTD, the ability of the HealthPartners Center for Memory and Aging's ability to sufficiently recruit subjects with FTD, and the safety of IN regular insulin administered 20 IU twice per day in two specific variants of FTD (behavioral variant frontotemporal dementia (bv-FTD), semantic dementia (SD)) over a 4 week period.

The current study examines the efficiency of a home-based computerized cognitive training (CT) intervention targeting older adults with diabetes.The primary aim of the study is to evaluate the effects of CCT on cognitive and disease management in non-demented older diabetes adults. Investigators will also evaluate the effect of the intervention on a range of secondary outcomes, including mood, caregiver burden, self-efficacy, and for a small sub-sample, on brain activity as reflected in changes in task-related blood-flow on fMRI.

Delirium is a common and serious condition and is associated with adverse outcome. The elderly who have cognitive dysfunction are expected to show delirium more frequently. It is most likely that delirium represents a response to impaired cholinergic neurotransmission. Investigators aimed to establish the preventive effect of the cholinesterase inhibitor, rivastigmine patch, on the post-operative delirium limited to femur neck fracture operation in patients at risk of dementia.

Physical activity exerts a variety of long-term health benefits in older adults.This randomised controlled trial investigates the effect of a 12-week physical exercise program on the change in cerebral metabolism as assessed with Magnetic Resonance Spectroscopic Imaging. Follow-up lasts for 6 months.

The purpose of this study is to develop a consistent approach to prevent falls with injury in nursing home (NH) residents. A centralized Injury Liaison Service (ILS) will be developed and tested in four nursing home facilities (two in the Durham, North Carolina area and two in the Boston, Massachusetts area). The ILS will combine successful elements of a Fracture Liaison Service (FLS) and video telehealth staff education (ECHO) models with the goal of decreasing injurious falls in nursing home residents. The ILS Program has four main components: Automated identification of NH residents at high risk for falls with injury Recommendations by the ILS nurse to manage medications, including deprescribing medications associated with falls and a prescription for osteoporosis medications Video telehealth sessions to educate staff Shared decision making with residents and/or families. The central hypothesis of this study is that the ILS model will reduce injurious falls by changing care delivery in two areas: deprescribing psychoactive and cardiometabolic drugs to reduce falls, and increasing osteoporosis treatment to prevent injury in the setting of a fall. Qualitative interviews will be conducted with nursing home staff to gain a better understanding of effective and non-effective injury prevention strategies. Information from these interviews will be incorporated into the study design. Outcome measures will focus on acceptability, demand, practicality, and feasibility of the program, as well as safety.
