Fact or Myth: "Dementia is a Normal Part of Aging"

With the increase in life expectancy and the number of people over the age of 65 expected to double in the next 40 years it is important to understand the difference between normal signs of aging and signs of dementia.  Normal cognitive changes can be mistaken as early stages of dementia but as we age these changes can be expected which is why it is important to distinguish between the two. 


According to the Alzheimer’s Society of Canada, almost 40 per cent of people over the age of 65 experience some form of memory loss. When there is no underlying medical condition causing this memory loss, it is known as "age-associated memory impairment," which is considered a part of the normal aging process.
