Filter by:The purpose of this study is to evaluate the changes in the cognitive, functional, behavioral and global domains based on the different applicable psychometric batteries and scales.
The purpose of this clinical study is to investigate the safety and efficacy of deep brain stimulation (DBS)as a treatment option for patients with cognitive, behavioral, and functional disability of Alzheimer's disease.
A few studies suggest that patients suffering from neurodegenerative diseases (such a multiple sclerosis or Alzheimer's disease (AD)) show decreased thickness of the retinal nerve fiber layer (RNFL), indicating axonal degeneration. High-definition spectral domain optical coherence tomography (SD-OCT), performed without radiation in a few seconds per eye, offers a precise and standardized estimation of this parameter, which could constitute a biomarker for cerebral axonal degeneration. These RNFL deficits might even be the earliest sign of AD, prior to damage of the hippocampal region that impacts memory. Besides, some associations of AD with some degenerative diseases of the eye (glaucoma, microvascular abnormalities, age-related macular degeneration (AMD)) have also been reported. It therefore seems interesting to determine whether RNFL thickness, and other ocular parameters, may give some indications for a better detection of AD and cognitive decline in the elderly.
The main purpose of this research project is to study how seizure-like activity affects the blood flow in the brain of patients with Alzheimer's disease (AD). Changes in blood flow can change memory and thinking ability, as happens in Alzheimer's disease. The investigators are using a study drug called Levetiracetam, which helps control seizure-like activity to see if it can help change the abnormal blood flow in the brain that is seen in some people with Alzheimer's disease.
This is an efficacy and safety study evaluating a new treatment for subjects with mild to moderate Alzheimer's disease.
The purpose of the study is to examine the safety, tolerability, immunogenicity and pharmacokinetics of TTP4000 in subjects with Alzheimer's disease with mild cognitive impairment.
Alzheimer's disease (AD) and related forms of dementia currently affect over 400,000 individuals in Canada and the numbers of community dwelling older adults with AD is rapidly growing. AD is associated with over $15 billion annually in care costs. Most individuals with AD are under the care of primary care providers (PCPs) including family physicians and primary care nurses. The evaluation and management of AD is challenging for PCPs and the quality of care provided to older adults with AD by PCP could be improved which would optimize outcomes for this vulnerable population. Provision of quality care to older adults with AD involves implementation of best practices as outlined in guidelines such as the Canadian Consensus Conference Guidelines on the Diagnosis and Treatment of Dementia. Utilizing a group of dementia researchers, PCPs, other knowledge users, and individuals affected by AD, this project will develop practical, clinically relevant resources for primary care physicians and nurses to aid in the evaluation of older adults with AD. A knowledge tool, the Primary Care - Dementia Assessment and Treatment Algorithm (DATA Tool) will be introduced into several primary care settings in Ontario using educational sessions with PCP with additional support from internet resource and a dementia care manager. The quality of dementia care provided to older adults newly diagnosed with AD will be assessed in the three years preceding the intervention compared to the year following the implementation. This project will also describe the process of knowledge exchange with PCPs, including potential barriers and facilitators of knowledge uptake and examine if the care provided during the intervention was patient-centred through interviews with patients and caregivers. Research Objectives: 1. Develop knowledge tools to facilitate assessment and treatment of AD by PCPs based on best evidence; 2. Transfer these knowledge tools into a variety of primary care settings in Ontario; and, 3. Evaluate the effects of this intervention on dementia quality of care, PCP application of knowledge, and the patient-centeredness of care.
The study will examine the effects of intranasally administered long-acting insulin detemir on cognition in persons with Alzheimer's disease (AD) or amnestic mild cognitive impairment (aMCI). The rationale for these studies is derived from growing evidence that insulin contributes to multiple brain functions, and that insulin dysregulation can contribute to AD pathogenesis. Thus, therapies aimed at restoring normal insulin signaling in the CNS may have beneficial effects on brain function. Intranasal administration of insulin increases insulin signaling in brain without raising peripheral levels and causing hypoglycemia. Insulin detemir is an insulin analogue that may have better action in brain than other insulin formulations because of its albumin binding properties. The investigators will test the therapeutic effects of intranasally-administered insulin detemir in a dose-finding study in which participants will receive one of two doses of insulin detemir or placebo for a three week period. The investigators will test the hypothesis that either dose will improve memory and daily functioning in persons with AD/aMCI compared with placebo.
This evaluation of the efficacy and safety of AXONA will be a chart review carried out at 16 practices in which AXONA has been prescribed for the treatment of patients with mild-to-moderate AD. Efficacy of AXONA will be assessed by comparison of patient status before and after initiation of treatment.
This study will assess the pharmacokinetics of MK-8931, a ß-secretase inhibitor, in participants with renal insufficiency. In Part 1 of the study, pharmacokinetics of MK-8931 in participants with severe renal disease and in healthy matched control participants will be studied. If data from Part 1 confirms that severe renal impairment does not alter the pharmacokinetics of MK-8931 to the extent requiring dosage adjustment, then no further study will be required and Part 2 will be optional. If the data does not support this conclusion, then Part 2 will be conducted to study the pharmacokinetics of MK-8931 in participants with moderate and mild renal impairment compared to healthy matched controls.
