Dementia is an umbrella term that encompasses a range of symptoms related to the loss of brain function and control. Memory loss; difficulty making yourself understood or being understood by others; disorientation; changes in mood and behavior; loss of motor coordination, etc. You are more at risk of suffering from it if you are over 65, or if you have suffered one or more concussions during your life.
We all experience minor memory lapses, especially as we age. This is normal.
If you’ve lost your keys, that happens to us — but if you can’t remember what your keys do, you may have dementia. If you sometimes forget your coat in the winter, you’re like the rest of us — but if you walk in the snow in the middle of winter in your underwear, that’s dementia.
According to Hope for Dementia, a non-profit organization, there are 700,000 Canadians currently suffering from dementia, and it’s estimated that number will reach one million by 2030. This represents a significant burden on society, particularly for the sons and daughters of those affected, who must take the time to care for them.
Dementia worsens over time if nothing is done. And yet, there are ways to prevent it, slow it down, or even reverse it, according to researchers. Here are 12 risk factors and how to avoid them, according to Hope for Dementia.
1. Physical inactivity
Exercise contributes to the prevention of dementia as it improves heart health, blood circulation and other risk factors such as obesity. Set aside 30 minutes each day for physical activity.
2. Excessive Alcohol Consumption
Heavy alcohol consumption is associated with several mental and physical disorders. Reducing alcohol consumption can protect your brain.
3. Smoking
Smoking increases the risk of vascular problems, including smoking and smaller bleeds in the brain.
4. Social Isolation
The quality, satisfaction, support and exchange of an active social life can reduce your risk of developing dementia. Stay connected regularly with family, friends and social groups.
5. Intellectual Stimulation
Education maintains a brain’s cognitive reserve – your resistance to brain damage. Challenge yourself by learning new things and engaging in new activities.
6. Obesity
Obesity is associated with dementia. Eat a balanced diet and get plenty of exercise.
7. Air Pollution
A growing amount of research links air pollution and dementia. Avoid busy streets at rush hour when traveling by car. Avoid wood fires. Consider installing an air filter.
8. Head Injury
Traumatic brain injury can lead to dementia many years after the injury. Wear a helmet when there is any risk of brain injury, including when cycling, skiing and playing a contact sport.
9. High Blood Pressure
There is a strong link between heart health and brain health. Maintaining a healthy cardiovascular system in important in preventing dementia. If you have hypertension, take your prescribed medication.
10. Diabetes
People with Type 2 Diabetes are at risk of dementia. Following prescribed medication and diet to control diabetes also helps control dementia.
11. Depression
If you constantly feel sad and discouraged, see your doctor. Ask for help through a combination of self-care, support groups and therapy.
12. Hearing Impairment
Wear hearing aids to balance any hearing loss and protection such as earmuffs or ear plugs when you can’t avoid excessive noise.
