The estimated dementia prevalence is lower than that in previous Brazilian epidemiological studies, but is in line with other Latin American studies. Only 1.2% of the ELSI-Brazil participants reported having a previous diagnosis of dementia, revealing that underdiagnosis is rampant and a common reality. Based on our results and national statistics projections, we estimate that in 2019 there were 1,757,480 million people aged 60 years and older living with dementia in Brazil and, at least, another 2,271,314 million having to deal with some form of cognitive impairment.
