          Abstract

          Resumen Objetivo: La enfermedad de Alzheimer (EA) es la demencia más común, y se estima que alrededor de 47 millones de personas a nivel mundial sufren esta enfermedad. Los inhibidores de la acetilcolinesterasa (IACE) y la memantina están indicados en estadios leve-moderado, pero su relevancia clínica está en entredicho y el uso de la terapia combinada no se ha establecido. El objetivo es medir la prevalencia de prescripción de fármacos para la EA en un Área de Gestión Sanitaria (AGS) y analizar tanto la utilidad de la biterapia como su potencial retirada. Metodología: Estudio retrospectivo desarrollado por el Servicio de Farmacia de un AGS que abarca 408.788 pacientes. Los datos se recogieron utilizando diferentes plataformas electrónicas del Servicio Andaluz de Salud. Se incluyeron todos los pacientes con prescripción activa de algún fármaco para la EA. Resultados: El 0,6% de la población total del AGS tenía prescrito uno o más fármacos para la EA. Los más prescritos fueron memantina y donepezilo tanto en monoterapia como combinados. Aproximadamente un 40% de los pacientes con terapia combinada sufrieron un deterioro cognitivo desde la instauración de la doble terapia, pero los fármacos no se retiraron. Conclusión: La prevalencia de prescripción de fármacos para la EA en el AGS estudiada es similar a los datos de prevalencia publicados. Desde el inicio de la prescripción de la terapia combinada hasta la última consulta médica, un porcentaje relevante de pacientes sufre deterioro cognitivo, pero los fármacos no se retiran, por lo que es necesario revisar las pautas de deprescripción de estos medicamentos.

          Abstract Objective: Alzheimer's disease (AD) is the most common dementia, and it is estimated that around 47 million people worldwide suffer this disease. Acetylcholinesterase inhibitors (AChEi) and memantine are indicated in mild-moderate stages, but their clinical relevance is questioned and the use of the combination therapy has not been established. The objective is to evaluate the prevalence of drug prescription for AD in a Health Management Area (HMA) and to analyze the utility of the dual therapy and its potential withdrawal. Methodology: Retrospective study developed by the Pharmacy Service of an HMS that includes 408,788 patients. Data were collected using different electronic platforms of the Andalusian Health Service. All patients with an active prescription of some drug for AD were included. Results: 0.6% of the total population of the HMS had prescribed one or more drugs for AD. The most prescribed were memantine and donepezil, both in monotherapy and in combination. Approximately 40% of patients with combination therapy suffered cognitive decline since the introduction of dual therapy, but the drugs were not withdrawn. Conclusion: The prevalence of drug prescription for AD in the HMS studied is similar to the published prevalence data. From the start of the combination therapy prescription until the last medical consultation, a relevant percentage of patients suffer cognitive impairment, but the drugs are not withdrawn, so it is necessary to review the deprescription guidelines.

          Alzheimer disease in the United States (2010-2050) estimated using the 2010 census.

          To provide updated estimates of Alzheimer disease (AD) dementia prevalence in the United States from 2010 through 2050. Probabilities of AD dementia incidence were calculated from a longitudinal, population-based study including substantial numbers of both black and white participants. Incidence probabilities for single year of age, race, and level of education were calculated using weighted logistic regression and AD dementia diagnosis from 2,577 detailed clinical evaluations of 1,913 people obtained from stratified random samples of previously disease-free individuals in a population of 10,800. These were combined with US mortality, education, and new US Census Bureau estimates of current and future population to estimate current and future numbers of people with AD dementia in the United States. We estimated that in 2010, there were 4.7 million individuals aged 65 years or older with AD dementia (95% confidence interval [CI] = 4.0-5.5). Of these, 0.7 million (95% CI = 0.4-0.9) were between 65 and 74 years, 2.3 million were between 75 and 84 years (95% CI = 1.7-2.9), and 1.8 million were 85 years or older (95% CI = 1.4-2.2). The total number of people with AD dementia in 2050 is projected to be 13.8 million, with 7.0 million aged 85 years or older. The number of people in the United States with AD dementia will increase dramatically in the next 40 years unless preventive measures are developed.

              Trends in the incidence and prevalence of Alzheimer's disease, dementia, and cognitive impairment in the United States.

              Declines in heart disease and stroke mortality rates are conventionally attributed to reductions in cigarette smoking, recognition and treatment of hypertension and diabetes, effective medications to improve serum lipid levels and to reduce clot formation, and general lifestyle improvements. Recent evidence implicates these and other cerebrovascular factors in the development of a substantial proportion of dementia cases. Analyses were undertaken to determine whether corresponding declines in age-specific prevalence and incidence rates for dementia and cognitive impairment have occurred in recent years. Data spanning 1 or 2 decades were examined from community-based epidemiological studies in Minnesota, Illinois, and Indiana, and from the Health and Retirement Study, which is a national survey. Although some decline was observed in the Minnesota cohort, no statistically significant trends were apparent in the community studies. A significant reduction in cognitive impairment measured by neuropsychological testing was identified in the national survey. Cautious optimism appears justified.
