Dementia is a common health problem in elderly people, Introduction Alzheimer disease (AD) being the most prevalent. AD can be considered as a cause of death and must be registered on the death certificate of the patients. However, most of the time, the main cause of death registered is not related to AD, but as an underlying or contributing cause. For example, individuals who have AD and die from myocardium infarction. This study aimed to analyze if nutritional status was associated with survival and mortality for AD, and if AD was reported as actual cause of death on the death certificate : The study was carried out as a cross-sectional study with elderly Methods citizens of the community registered in the National Health System (SUS), with cognitive, nutritional, biochemical and hematological evaluations of 30 AD patients in Guarapuava, Paraná state, Brazil. : Significant differences were not observed between live and dead Results patients when evaluated considering the methods applied. Only 22% of the death certificates stated death due to AD. The patient's cause of death showed a strong relation to respiratory issues; potential explanations based on immunological, biochemical and comorbidity were not confirmed on this study.: AD was not declared as the cause of death in the majority of Conclusions certificates, contributing to the underreporting and reducing the information of death due to AD in the country.
Introduction: Alzheimer's disease (AD) is a public health problem in Brazil due to the growing number of older adults in this population. Knowing the prevalence of AD in the Paraná state is essential to improve patients’ quality of life. The objective of the study was to estimate AD prevalence in the state of Paraná, based on the prescription of anticholinesterases, from 2012 to 2017. Methods: Patients diagnosed with AD, aged 60 years or over, who used Brazil’s Unified Public Health System (SUS) and received AD medication from the Department of Pharmaceutical Assistance of the state of Paraná, from 2012 to 2017, were the target population of the present study. The medication data were collected from the Computerized system management and Monitoring of Exceptional Drugs (SISMEDEX), and the population’s data were collected from the Brazilian Institute of Geography and Statistics (IBGE). Results: The sample consisted of 52,687 patients, and the median prevalence of AD in the established period for the state was 642.6/100,000 inhabitants (0.64%). In all ages and macro-regions, women showed the highest prevalence rates. The median prevalence for women in the established period was 755.4/100,000 inhabitants (0.75%). Among men, the median prevalence was 510.2/100,000 inhabitants (0.51%). In the temporal analysis of prevalence, between 2012 and 2017, a reduction of 23% was found in the state rate. The prevalence rate of Paraná for AD is nine times lower than the Brazilian average. Conclusions: Paraná’s prevalence rate for AD is lower than the rates of Brazil and the world, suggesting that AD is underdiagnosed in most municipalities of this state.
