BACKGROUND Cognitive decline among seniors is a pressing health care issue. Specific exercise training may combat cognitive decline. We compared the effect of once-weekly and twice-weekly resistance training with that of twice-weekly balance and tone exercise training on the performance of executive cognitive functions in senior women. METHODS In this(More)
OBJECTIVES To assess whether the core symptoms of Alzheimer disease (AD) consistently predict patient self-rated quality of life (QOL) as assessed by a variety of QOL measures in a large national sample of AD patients. DESIGN Cross-sectional. SETTING Fifteen dementia and geriatric clinics across Canada. PARTICIPANTS Community-living patients with AD(More)
OBJECTIVES To assess whether the core symptoms of Alzheimer disease (AD) and caregiver factors consistently predict family caregiver ratings of patient quality of life (QOL) as assessed by a variety of QOL measures in a large national sample. DESIGN : Cross-sectional. SETTING Fifteen dementia and geriatric clinics across Canada. PARTICIPANTS : Family(More)
The basal nuclei of Meynert are the principal sources of cholinergic innervation of the cerebral cortex. It has been hypothesized that the depressed cortical glucose metabolic activity in senile dementia of Alzheimer's type (SDAT) may result primarily from diminished activity and loss of these cells. The present study was designed to test the hypothesis(More)
Most ethical guidelines strongly promote disclosure of a diagnosis of dementia to the affected individual, based on the principle of autonomy. Nevertheless, codes of medical ethics allow for various interpretations of this issue and surveys of clinical practice illustrate that such disclosure is by no means the rule. We argue that diagnostic disclosure for(More)
We report secondary findings from a randomized controlled trial on the effects of exercise on memory in older adults with probable MCI. We randomized 86 women aged 70-80 years with subjective memory complaints into one of three groups: resistance training, aerobic training, or balance and tone (control). All participants exercised twice per week for six(More)
BACKGROUND Falls are a major health care problem for older people and are associated with cognitive dysfunction. Mild cognitive impairment (MCI) is an increasingly recognized clinical problem. No study has comprehensively compared people with and without MCI for fall risk factors in both the physiological and cognitive domains. OBJECTIVE The purpose of(More)
BACKGROUND Mild cognitive impairment (MCI) represents a critical window to intervene against dementia. Exercise training is a promising intervention strategy, but the efficiency (i.e., relationship of costs and consequences) of such types of training remains unknown. Thus, we estimated the incremental cost-effectiveness of resistance training or aerobic(More)
BACKGROUND/AIMS Cognitive impairment no dementia (CIND) describes individuals whose cognitive functioning falls below normal but who do not meet dementia criteria. An important goal within CIND is to identify subgroups that will predictably progress to Alzheimer disease. CIND with amnestic deficits has been associated with high risk of Alzheimer disease but(More)
Online social media is widespread, easily accessible and attracts a global audience with a widening demographic. As a large proportion of adults now seek health information online and through social media applications, communication about health has become increasingly interactive and dynamic. Online health information has the potential to significantly(More)
