The importance of brain health
Promoting brain health is important because our brain is the control centre of our body and plays a critical role in our overall well-being. The brain controls everything from our thoughts, emotions, and behaviour to our movement, senses, and bodily functions. Maintaining good brain health can help prevent or delay the onset of cognitive decline and brain diseases such as Alzheimer’s disease.
Recent research has shown that there are several actions you can take to promote brain health and delay or prevent cognitive impairment.
It is never too early or too late to reduce your risk of dementia.

What is dementia?
Dementia is a progressive brain disease that affects our cognition.
Cognition is our ability to interact with the world around us. It includes many important functions, such as:
- learning and memory - our ability to remember conversations and events or learn new information;
- language - reading, writing, speaking and understanding;
- visual and spatial function – how we navigate around our environment;
- executive function - how we make decisions, solve problems and organize our life; and
- social function - how we interact appropriately with our family, friends, and colleagues.
What are cognitive changes associated with aging?
As we age, some of our cognitive abilities gradually decline. We can’t remember quite as much when learning new information; we don’t process things quite as fast, and learning more complicated tasks becomes more difficult. We do, however, continue to make lifelong memories, and even our vocabularies and wisdom may continue to improve into later life.
The changes associated with aging are subtle. For instance, somebody forgetting what they ate for breakfast by lunchtime would never be associated with normal aging. Some degree of cognitive decline is normal and expected as we age; but, importantly, the changes associated with normal aging don’t impact an individual’s ability to function independently.
How is dementia diagnosed?
There is no one test to determine if someone has dementia. Health care professionals diagnose the different types of dementia based on:
- a careful medical history,
- a physical examination,
- laboratory tests,
- pen and paper tests that evaluate cognitive function,
- the characteristic changes in thinking, day-to-day function and behaviour associated with each different type of dementia.
