43/100

✓ Peer-reviewed alzhub usefulness score 43 out of 100. Risk factors

Topic: Risk, prevention and care in population studies

Fifteen experts, with a mean professional experience of 25 ± 10 years, reached a consensus in the fourth round. Experts agreed with a mean all-cause dementia prevalence of 8.5% among Brazilians aged ≥ 60 years, which comprised 2.46 million people in 2019 in this age. They reported higher dementia rates in women (9.1%) than men (7.7%); the highest total prevalence was in those over 80 where it exceeds 20%. Regional variations were also noted, with lower prevalence in the South (7.3%) and higher in the North (8.9%) and Northeast (10.1%). Projections estimate that considering Brazil's rapidly aging population, dementia cases will rise to 8.89 million by 2060. This Delphi study estimated that dementia already affects roughly 1 in 12 older Brazilians aged 60 and above, with slightly higher prevalence in women and significant geographical variations. These results underscore the urgency for targeted public health strategies in Brazil and offer a framework for similar challenges in other LMICs, especially given that dementia cases are projected to increase by approximately 3.6 times in 4 decades.

Key findings

Fifteen experts, with a mean professional experience of 25 ± 10 years, reached a consensus in the fourth round.
Experts agreed with a mean all-cause dementia prevalence of 8.5% among Brazilians aged ≥ 60 years, which comprised 2.46 million people in 2019 in this age.
They reported higher dementia rates in women (9.1%) than men (7.7%); the highest total prevalence was in those over 80 where it exceeds 20%.
Regional variations were also noted, with lower prevalence in the South (7.3%) and higher in the North (8.9%) and Northeast (10.1%).
Projections estimate that considering Brazil's rapidly aging population, dementia cases will rise to 8.89 million by 2060.

Why it matters

A panel of experts estimated that dementia affects about 1 in 12 Brazilians aged 60 and over, with higher rates in women and regional variation, and projected cases would rise to 8.89 million by 2060. These are consensus estimates meant to guide public health planning, not findings about treatment or prevention.
