Neurological health concerns are increasing in Brazil, specifically regarding cognitive decline, dementia, and multiple sclerosis. Experts have warned of a rising epidemic of mental health issues and premature cognitive decline, with projections suggesting that by 2050, half of all elderly individuals may suffer from Alzheimer’s.

Data from the Ministry of Health indicates that approximately 1.85 million people in Brazil currently live with dementia, a figure expected to more than triple by 2050. Studies estimate that 8.5% of Brazilians aged 60 or older suffer from some form of dementia, with higher prevalence in the Northeast region.

Medical professionals have noted a phenomenon called ‘psychologization,’ where symptoms of neurodegenerative diseases—such as irritability and mood changes—are misattributed to mental health issues like anxiety or burnout, potentially delaying treatment. Additionally, researchers are investigating the progression of multiple sclerosis in Brazil, which affects roughly 40,000 people, through studies on the HTLV-1 retrovirus.
