Islanders are encouraged to take a quiz to learn how to prevent dementia.
The rate of people affected by the disease is the fastest-growing in over 65s.
Dementia Jersey has found simple lifestyle changes can make a difference.
CEO Claudine Snape says the quiz helps people to understand the risks.
"Take the quiz and it gives some tailored feedback on what to do.
"We know that up to 45% of cases can be avoided with simple lifestyle changes."

The new quiz takes people through three key areas:
- Love Your Heart,
- Stay Sharp
- And, Keep Connected.
Questions are asked about each topic, whether that is smoking and drinking habits, or what someone does in their spare time.
The answers to the queries indicate how well islanders are preventing dementia.
The charity is pushing the message by advertising on buses, walls around town and plant pots in Liberty Wharf.

Claudine Snape says dementia is not an inevitable part of ageing.
"We know there is something that you can do to help with your own individual risk, so we want everyone to hear about it.
"Modifiable risk factors of dementia, those things that you can change due to your lifestyle, are all part of a piece of research and they've identified a number of different things.
"We've grouped it into three areas to make it easy for people to take action.
"That's why we're saying 'look after your heat, stay sharp and stay connected.'"
