Dementia is not part of normal aging, although the elderly are more prone. It describes a group of symptoms such as memory loss, impaired judgment, confusion and behavioural changes, which are severe enough to affect daily function.
Losing one's memory is a terrible experience – one which a person with dementia has to live with.
To reduce your risk of getting dementia, Clinical Assistant Professor Vanessa Mok, Senior Consultant for Psychological Medicine, and Anuradha Kaliappan, a Senior Medical Social Worker, both from Changi General Hospital (CGH), a member of the SingHealth group, share some simple steps you can take.
What is dementia?
Dementia describes a group of symptoms such as memory loss, impaired judgment, confusion and behavioural changes, which are severe enough to cause loss of function.
Dementia is not part of normal aging, though the elderly are more prone. Dementia occurs when the brain function gradually fails, affecting day-to-day activities.
Alzheimer’s disease is the most common type of dementia, followed by vascular dementia. It affects mainly elderly people.
In Singapore, the prevalence rate of dementia in people above 65 years is 6.2%. It is an illness that causes significant distress to both the patient and his caregivers.
Symptoms of dementia
All types of dementia involve decline in mental abilities involving thinking and memory, but the specific symptoms vary depending on the type of dementia. Persons suffering from dementia may have difficulties with:
Tips to prevent dementia
However, there are simple things you can do that may help lower your risk of getting dementia:
1. Eat a healthy, balanced dietA Mediterranean diet, consisting of plenty of fish like salmon and mackerel, vegetables, grains and nuts, in combination with a low salt diet is beneficial for the brain and heart.
Another simple way to remember a well-balanced diet is to follow the My Healthy Plate - filling half of your plate with fruit and vegetables, a quarter with wholegrains and a quarter with protein-rich food such as meat, fish, and tofu.
In addition to keeping your brain healthy, reducing salt and sugar intake also helps keep chronic illnesses at bay such as high blood pressure (hypertension) and diabetes (Type 2 Diabetes Mellitus).
2. Be physically active and exercise regularlyThirty minutes of moderate intensity exercise daily, five times a week, is the recommended minimum. The activity has to be intense enough to raise your heart rate and get you a bit out of breath. You could walk, cycle, swim or join an exercise or dance group. Regular exercise makes your heart and blood circulatory system more efficient, helping to lower cholesterol and blood pressure. Exercise is also good for your mental well-being.
3. Maintain a healthy weightGo for regular health checks to monitor blood pressure, blood sugar and cholesterol levels. Follow your doctor's advice on exercise and diet. Maintaining a healthy weight also helps to reduce your risk of heart disease, stroke and diabetes.
4. Don’t smokeSmoking and vaping harms your lungs, heart and blood circulation. If you smoke, try to stop. Stopping smoking at any age can improve your health and lower your risk of heart attack, stroke, and lung disease. Check out this article for tips on how to quit smoking.

5. Drink alcohol in moderationSome studies have shown that alcohol consumption is linked to dementia. To lower the risk of alcohol-related harm over a lifetime, men should drink no more than two standard drinks per day, and women no more than one standard drink per day. If you must drink alcohol, moderation is key.
6. Give your brain a daily workoutSome studies have shown that keeping mentally active and maintaining strong social connections may lower the risk of cognitive decline.
Activities could include reading, solving puzzles, playing number or word games, playing cards or learning something new. Social engagement can be achieved by visiting family or friends or have them visit you, joining a club or volunteering for a cause you believe in.
It is not possible to reverse our age, change our genes and there is no sure way to prevent dementia. The key to lowering the risk for dementia is to lead a healthy lifestyle, and engage in regular physical and mental activity. It is never too early to develop good habits, and it may be easier to adopt a healthier lifestyle if it is incorporated into your daily routine.
Some studies show that reduced sleep worsens the clearance of proteins that may be harmful to the brain. This may possibly lead to the accumulation of these toxic proteins, leading to dementia.
Try to get seven to nine hours of sleep each night. Consult your doctor if you are not getting enough sleep, sleeping poorly or think you may have a sleep disorder such as obstructive sleep apnea (OSA).
Ensure regular visits to the doctor and keep medical conditions like diabetes, high blood pressure (hypertension) and high blood cholesterol (hypercholesterolaemia) in check.
These diseases increase the risk of blockage of blood vessels, which predisposes one to develop vascular dementia.
A strong and healthy heart ensures adequate blood flow to the brain, keeping it well-nourished and healthy.
If you are taking medications for chronic conditions, do it dutifully and seek early treatment to avoid any complications that may result from these conditions.
