Abstract Introduction In 2010, Alzheimer's Disease International presented estimates of the global cost illness (COI) dementia. Since then, new studies have been conducted, and number people with dementia has increased. Here, we present an update estimates. Methods This is a societal, prevalence‐based COI study. Results The worldwide costs were estimated at United States (US) $818 billion in 2015, increase 35% since 2010; 86% occur high‐income countries. Costs informal care direct social...

Abstract Introduction Dementia is a leading cause of death and disability globally. Estimating total societal costs demonstrates the wide impact dementia its main direct indirect economic components. Methods We constructed global cost model for dementia, presenting as cumulated regional costs. Results In 2019, annual were estimated at US $1313.4 billion 55.2 million people with corresponding to $23,796 per person dementia. Of total, $213.2 (16%) medical costs, $448.7 (34%) social sector...

Abstract Background Subjective cognitive decline (SCD) is recognized as a risk stage for Alzheimer’s disease (AD) and other dementias, but its prevalence not well known. We aimed to use uniform criteria better estimate SCD across international cohorts. Methods combined individual participant data 16 cohorts from 15 countries (members of the COSMIC consortium) used qualitative quantitative (Item Response Theory/IRT) harmonization techniques prevalence. Results The sample comprised 39,387...

empirical evidence from high-income countries suggests that self-rated health (SRH) is useful as a brief and simple outcome measure in public research. However, many low- middle-income (LMIC) there lack of evaluation the cross-cultural validity SRH remains largely untested. This study aims to explore prevalence its association with mortality older adults LMIC order cross-culturally validate construct SRH. population-based cohort studies including 16,940 persons aged ≥65 years China, India,...

Systolic interarm differences in blood pressure have been associated with all-cause mortality and cardiovascular disease. We undertook individual participant data meta-analyses to (1) quantify independent associations of systolic difference events; (2) develop validate prognostic models incorporating difference, (3) determine whether remains risk after adjustment for common scores. searched studies recording bilateral outcomes, established agreements collaborating authors, created a single...
