description | The prevalence of dementia varies substantially worldwide. This is partially attributed to the lack of methodological uniformity among studies, including diagnostic criteria and different mean population ages. However, even after considering these potential sources of bias, differences in age-adjusted dementia prevalence still exist among regions of the world. In Latin America, the prevalence of dementia is higher than expected for its level of population aging. This phenomenon occurs due to the combination of low average educational attainment and high vascular risk profile. Among developed countries, Japan seems to have the lowest prevalence of dementia. Studies that evaluated the immigration effect of the Japanese and blacks to USA evidenced that acculturation increases the relative proportion of AD cases compared to VaD. In the Middle East and Africa, the number of dementia cases will be expressive by 2040. In general, low educational background and other socioeconomic factors have been associated with high risk of obesity, sedentarism, diabetes, hypertension, dyslipidemia, and metabolic syndrome, all of which also raise the risk of VaD and AD. Regulating these factors is critical to generate the commitment to make dementia a public health priority. |
