The Dementia: Understand Together campaign, led by the HSE in partnership with The Alzheimer Society of Ireland, Age Friendly Ireland, Age & Opportunity, Healthy Ireland and the Dementia Services Information and Development Centre, is encouraging everyone to make simple changes to help maintain brain health and reduce the risk of developing some types of dementia.
This year’s theme is Focus on the Brain, a great reminder just how amazing our brains are and how important it is to look after them.

A study by The Lancet (registration required for free access) in 2024 identified 14 modifiable risk factors that could account for up to 45% of dementia worldwide. We’re highlighting a number of these factors, creating awareness of the link with dementia and how people can reduce their risk.
Proactive steps people can take include:
•being physically active
•eating a healthy balanced diet
•quitting smoking
•managing blood pressure
•looking after your hearing and vison
•making time for social connection and interaction.
Adopting these habits in adulthood can play an important part in reducing risk, as well as developing good routines for life.
