Why dementia is not a normal part of aging and what you can do

Dementia is a broad term to describe the symptoms that affect brain function. It’s a condition characterized by:

• Loss of memory, judgement and reasoning
• Changes in behaviour and mood
• Physical changes like loss of coordination, balance and mobility

These changes often result in a progressive decline in a person’s ability to function at work and in social relationships, or to perform regular daily activities.

It’s important to know that dementia is not a normal part of aging. Dementia is diagnosed by health-care professionals.

Alzheimer’s disease is the most common form of dementia. It’s estimated to contribute to 60–70 per cent of dementia cases. There’s no cure for Alzheimer’s and it’s not reversible, though some medicines might slow it down for a while and make the disease easier to live with.

What is Alzheimer's disease? (Alzheimer Society of Canada)

The risk of getting dementia or Alzheimer’s is influenced by factors that include your lifestyle, environment and genetics.

Some factors you can control; others you cannot. Like most diseases, risk factors represent an increased chance that dementia will develop—but is not a certainty. Conversely, having little to no risk factor exposure doesn’t mean you’re protected from getting dementia.

You can reduce the risk of getting dementia by paying attention to the following risk factors. It’s estimated 40 per cent of dementia cases may be the result of these modifiable factors:

• High blood pressure
• Smoking
• Diabetes
• Lack of physical activity
• Obesity
• Diet
• Alcohol consumption
• Low levels of cognitive engagement
• Depression
• Traumatic brain injury
• Hearing loss
• Social isolation
• Air pollution

An important step anyone can take is to think about, write down and talk about your wishes and instructions for personal and health care needs.

Advance care planning can begin at any stage of your life. We make our best decisions when we are calm and before we are in a stressful situation or medical crisis. Even if you’re feeling well and healthy now, it’s a good idea to be prepared in case you become suddenly unwell and not able to make decisions for yourself.
