A lifelong approach to brain health
Understanding the modifiable risk factors for Alzheimer’s disease and dementia.
What the research says
The 2024 Lancet Commission identifies 14 potentially modifiable dementia risk factors across life, including hearing loss, high LDL cholesterol, physical inactivity, and untreated vision loss. It estimates that addressing these factors could prevent or delay approximately 45% of cases at a population level.
What it doesn’t tell us
This is a population-level estimate, not a promise that any individual can prevent dementia. Some risk factors are shaped by social conditions and access to care.
