Overview

• Brazil records about 100,000 new Alzheimer’s cases each year as population aging drives rising diagnoses.
• The disease accounts for an estimated 60%–70% of dementia cases worldwide, and roughly 1.8 million Brazilians aged 60+ live with some form of dementia.
• In Piauí, state data show 118 dementia diagnoses from 2020 to 2025, with free care starting at UBS units and referrals to specialized clinics in Teresina.
• Experts emphasize modifiable risks such as hypertension, diabetes, inactivity, social isolation and poor sleep, with one study suggesting about 48% of cases are linked to preventable conditions.
• There is no cure, but multidisciplinary care and newer options like anti-amyloid therapies can slow decline, while caregivers rely on calm communication, meaningful memories and structured routines.
