Reduce your risk of dementia

Some dementia cases can’t be avoided, but up to 45% of cases could be delayed or prevented. There are things you can do through your life to reduce your risk of dementia – and you may already be doing some of them. It’s never too early or too late to start.

Stay active and eat a balanced diet

  • Physical activity reduces dementia risk. The 24 hour movement guidelines outline how much physical activity is recommended for each age group.
  • A healthy diet targets dementia risk factors of obesity, diabetes and hypertension. Eat for Health has advice about eating a balanced diet 

Get regular hearing and vision checks

  • Hearing loss is linked to increased risk of dementia. Use noise protection and treat ear infections. 
  • Using hearing aids lowers the dementia risk. The Hearing Services Program supports access to hearing devices. 
  • Untreated vision loss is a risk factor. Many optometrists will bulk bill eye tests under Medicare.

Look after your heart health and manage diabetes

  • High blood pressure, high ‘bad’ LDL cholesterol and diabetes can each increase dementia risk. 
  • You might not be showing any symptoms, so regular health checks are important. 
  • You may be eligible for a fully subsidised health assessment or heart health check – talk to your GP.
  • Many pharmacies offer free blood pressure checks and you can check your type 2 diabetes risk at AUSDRISK.

Seek help for mental health 

Quit smoking and limit alcohol

  • Smoking is a known risk factor for dementia as well as many other chronic conditions. 
  • Give up for good to reduce your risk of dementia. 
  • Heavy alcohol consumption is also linked to dementia. Cut down to reduce your dementia risk. 

Be social and keep your brain active

  • Social isolation or infrequent social contact is a risk factor for dementia.  Connect with others through hobbies, interests or volunteering. 
  • Engage in mentally stimulating activities that challenge your brain in new ways throughout your life.
