OBJECTIVES This article describes the development of an assessment of functional disability for use with proxy-respondents of community-dwelling persons who have Alzheimer's disease as well as a study testing its reliability. METHOD Panels composed of health care professionals and caregivers of persons with Alzheimer's disease were used to develop the(More)
Functional impairment is a core symptom of Alzheimer's disease. The most accurate indicator of functional impairment is the decline in performance of Activities of Daily Living (ADL). Several scales have been used to measure ADL in geriatric and Alzheimer's disease (AD) populations including the Disability Assessment for Dementia (DAD). The key to making a(More)
Although spatial disorientation is frequently observed in persons with Alzheimer disease, it is not well understood. A descriptive study was conducted to examine spatial skills associated with spatial orientation. Spatial tasks were selected and grouped into three types of spatial skills: perceptual, cognitive, and functional. These spatial tasks were(More)
Neurotransmitter replacement therapy in Alzheimer's Disease is currently being attempted using bethanechol chloride (Urecholine) infused intracerebroventricularly with an Infusaid continuous infusion pump. The rationale of this therapy is based on the severe cortical pre-synaptic cholinergic deficit in the presence of relatively normal post-synaptic(More)
The use of fluoroscopy in interventional cardiology procedures may expose patients to levels of radiation that manifest in unintended outcomes. Such outcomes may include skin injury and cancer. Currently, there is limited understanding of the magnitude of dose administered in an individual procedure. Canada does not have a formal policy for monitoring and(More)
Several lines of evidence have implicated acetylcholine (ACh) as one of the neurotransmitters found to be decreased in Alzheimer's disease (AD). Various methods of cholinergic augmentation have been attempted, with mixed results. Tetrahydroaminoacridine (THA), an acetylcholinesterase inhibitor, is currently being investigated at the McGill Centre for(More)
Early reperfusion of the myocardium is crucial in treating patients with acute ST segment elevation myocardial infarction (STEMI). Emergency medical services (EMS) plays an important role in minimizing delays to reperfusion. This study demonstrates that a large proportion of patients presenting with STEMI do not use EMS. Thus, such patients cannot benefit(More)
