Preventing dementia by preventing stroke: The Berlin Manifesto

Abstract: The incidence of stroke and dementia are diverging across the world, rising for those in low- and middle-income countries and falling in those in high-income countries. This suggests that whatever factors cause these trends are potentially modifiable. At the population level, neurological disorders as a group account for the largest proportion of disability-adjusted life years globally (10%). Among neurological disorders, stroke (42%) and dementia (10%) dominate. Stroke and dementia confer risks for each other and share some of the same, largely modifiable, risk and protective factors. In principle, 90% of strokes and 35% of dementias have been estimated to be preventable. Because a stroke doubles the chance of developing dementia and stroke is more common than dementia, more than a third of dementias could be prevented by preventing stroke. Developments at the pathological, pathophysiological, and clinical level also point to new directions. Growing understanding of brain pathophysiology has unveiled the reciprocal interaction of cerebrovascular disease and neurodegeneration identifying new therapeutic targets to include protection of the endothelium, the blood-brain barrier, and other components of the neurovascular unit. In addition, targeting amyloid angiopathy aspects of inflammation and genetic manipulation hold new testable promise. In the meantime, accumulating evidence suggests that whole populations experiencing improved education, and lower vascular risk factor profiles (e.g., reduced prevalence of smoking) and vascular disease, including stroke, have better cognitive function and lower dementia rates. At the individual levels, trials have demonstrated that anticoagulation of atrial fibrillation can reduce the risk of dementia by 48% and that systolic blood pressure lower than 140 mmHg may be better for the brain. Based on these considerations, the World Stroke Organization has issued a proclamation, endorsed by all the major international organizations focused on global brain and cardiovascular health, calling for the joint prevention of stroke and dementia. This article summarizes the evidence for translation into action.

A validation study of The Geriatric Depression Scale short form

Abstract: The validity of the Geriatric Depression Scale (GDS) short form was assessed in a geriatric affective disorders outpatient clinic (N = 116). The GDS was highly correlated with the Montgomery Asberg Depression Rating Scale (MADRS), and with optimal cutoff scores of 5/6, demonstrated a sensitivity of 85% and a specificity of 74.0%. The GDS appears to be a useful, valid screening instrument in this population.

Exercise for people with cancer: a clinical practice guideline

Abstract: Background Development of this guideline was undertaken by the Exercise for People with Cancer Guideline Development Group, a group organized by Cancer Care Ontario’s Program in Evidence-Based Care (pebc). The purpose of the guideline was to provide guidance for clinicians with respect to exercise for patients living with cancer, focusing on the benefits of specific types of exercise, recommendations about screening requirements for new referrals, and safety concerns. Methods Consistent with the pebc’s standardized approach, a systematic search was conducted for existing guidelines, and systematic literature searches were performed in medline and embase for both systematic reviews and primary literature. Content and methodology experts performed an internal review, which was followed by an external review by targeted experts and intended users. Results The search identified three guidelines, eighteen systematic reviews, and twenty-nine randomized controlled trials with relevance to the topic. The present guideline provides recommendations for the duration, frequency, and intensity of exercise appropriate for people living with cancer. It also provides recommendations for pre-exercise assessment, safety concerns, and delivery models. Conclusions There is sufficient evidence to show that exercise provides benefits in quality of life and muscular and aerobic fitness for people with cancer both during and after treatment, and that it does not cause harm. The present guideline is intended to support the Canadian Society for Exercise Physiology’s Canadian physical activity guidelines. The recommendations are intended for clinicians and institutions treating cancer patients in Ontario, and for policymakers and program planners involved in the delivery of exercise programs for cancer patients.
