Dementia consultant Kay Miller said developing dementia could not be stopped altogether, nor was there a cure, but setting good habits at all ages was proven to help prevent the impact of dementia.

Your Brain Matters information session, based on published research evidence, on Wednesday aims to equip Ballarat residents with key steps to live a brain-healthy life.

"One thing you can't change is your age, and age is the biggest risk factor," Ms Miller said. "Evidence tells us what you do in middle age can help in older age."

Ms Miller said awareness about dementia was spreading in Ballarat, particularly helped by the city's young champions, but ways to reduce risk were still not well-known.

One: Look after your heart. What's good for your heart is good for your brain.

Two: Do some physical activity. Physical activity increases blood flow to the brain, stimulates the growth of brain cells and the connection between them.

Three: Mentally challenge your brain. Challenging the brain with new activities helps to build new brain cells and strengthen connections between them.

Four: Follow a healthy diet. A healthy, balanced diet that includes vegetables, fruit, fish, grains, nuts, legumes (beans, peas and lentils), and lean meat may help in maintaining brain health and functionality.

Five: Enjoy social activity. Social interaction with people whose company you enjoy can help to look after the health of your brain.

There are an estimated 112,000 people living with dementia in Victoria, including more than 3,100 in Ballarat.

Your Brain Matters will be at Ballarat Community Health's Lucas hub on Wednesday, from 10.30am, with a chance to speak to dementia consultants and source more information.
