Filter by:This is a study to evaluate the efficacy and safety of azeliragon in patients with mild Alzheimer's disease and impaired glucose tolerance. Patients will receive either azeliragon or placebo with a patient's participation lasting approximately 9 months (in Part 1) or 21 months (in Part 2).
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 is a first in human Phase 1 study in two parts with healthy volunteers receiving a single dose of PU AD in three small cohorts and a multiple ascending dose in two small cohorts.
Mindfulness Based Health Care (MBHC) includes meditation techniques to help caregivers of Alzheimer patients to be made more aware of their experience in the present moment. Half of the caregivers will learn the practice of mindfulness meditation once a week through 8 classes, and the other half will not receive any therapy. The primary purpose of this study is to explore the effects of this mindfulness program for caregivers on the neuropsychiatric symptoms in Alzheimer patients, as well as on anxiety and depression symptoms in their caregivers. Secondarily, to examine the effect of this program on cognitive function, daily activity living and quality of life in Alzheimer patients, as well as on the burden of caregiving, quality of life, psychological well-being, occupational balance, executive function and self-compassion in their caregivers.
The purpose of this study is to study the effect of monthly dosing with a single dose of Lu AF20513, with and without booster vaccine, on antibody response.
The purpose of this study is to investigate the influence of acupuncture on heart rate variability, skin conductance (sweating), and rated behavioral expression of agitation, irritability, and anxiety and mood in qualifying adults with a diagnosis of cognitively unimpaired, or probable Alzheimer's Disease, Frontotemporal Dementia or Dementia with Lewy Bodies. Study subjects will all receive one real acupuncture treatment; mood scales will be assessed before and after. Massachusetts General Hospital is paying for this research to be done.
This study will evaluate behavioral and electrophysiological changes in a sample of adults with possible or probable Alzheimer's disease (AD), before and after undergoing training using a brain-computer interface (BCI) system with neurofeedback based on electroencephalography (EEG). Participants will repeatedly complete a letter viewing task and receive visual and auditory cues about their brainwaves. The study team hypothesizes that exposure to this EEG-based biofeedback intervention (neurofeedback) will result in a reduction of theta activity (brainwaves in the range of 4-8 Hz). The study team also predicts that exposure to the neurofeedback intervention will result in increased performance on reading, attention, and working memory tasks.
This is a cross-sectional pilot study of Alzheimer's disease (AD) brain imaging biomarkers in Diabetes Prevention Program (DPP) outcomes study (DPPOS) participants from the New York City sites (Columbia and Einstein), comparing 10 persons originally randomized to metformin and 10 persons randomized to placebo in DPP. All study procedures will be conducted at Columbia University Irving Medical Center. Eligible participants will receive a PET scans and a brain MRI, which may be conducted in one, two, or three separate visits.
The investigators don't know yet how the nose and the brain decode the smells. Scientific studies in neuroscience have shown that people who have tumors may have changes in the smell of secretions. Dogs are extremely efficient at detecting these changes, even before imaging studies. A review of the recent literature shows the different work done on the diagnosis of dogs on human pathologies, especially oncology. It is now known that the smell of exhaled gases is representative of the intestinal biotope and that a large number of pathologies are related to the type of microbial populations that inhabit the intestines. Copying the olfactory organs could thus be of major interest for the early diagnosis of pathologies. More and more works are interested in the diagnostic power of electronic noses. From a technical point of view, these are nano-sensors that mimic the olfactory receptors from the breath gas of the subjects. They analyze the molecules present and compare them with a database to establish a diagnosis according to a probabilistic algorithm. The use of exhaled air for the diagnosis of cancerous pathologies has already been the subject of scientific work. A classification using the SVM (support vector machine) method using data from 320 sensors made it possible to differentiate patients with lung cancer from controls in 98.8% of cases. The differential diagnosis of obstructive bronchopneumopathy was also very well done in this same study. Another study shows equally encouraging results, highlighting sensitivities and specificities above 80%.
The purpose of this study is to assess the long-term safety and tolerability of ABBV-8E12 in participants with early AD.
