Original available at: http://www.revistaccuba.cu/index.php/acc/article/view/126 Dementia is a syndrome that has great repercussions for quality of life of patients and their families, as well as a high social cost. A [2009] systematic review of research evidence and consensus of expert opinions showed that 36 million people live with dementia worldwide, with 4.6 million new cases every year (similar to the global incidence of nonfatal stroke). The prevalence of dementia in older Cubans is high, with rates ranging from 6.4% to 10.2%, or about 130,000 persons (1.1% of the total population). This number is expected to rise to 260,000 by 2030. The age-standardized annual incidence of dementia is also high: 21 per 1000 population, with 28,750 new cases annually. Dementia is the leading cause of disability among older adults and is the main cause of dependency, financial burden and caregiver stress. In this review, we highlight the importance of epidemiological research to obtain greater knowledge of the disease, improve health services, promote actions for prevention and early diagnosis, and implement a national strategy to address dementia in the Cuban population, itself now immersed in two processes: accelerated demographic aging and epidemiologic transition.
