Forgetting where you put something or a failing to recall a person’s name can happen to anyone. However it becomes much more distressing when frequent memory loss begins to affect our daily lives and in some cases, can eventually cause us to lose our independence.
While impaired memory could be the result of infection, depression or anxiety or other medical conditions, it may also be due to dementia.
Impaired memory loss may be due to dementia, which impacts more than half a million Canadians and is expected to nearly double by 2030, according to the Alzheimer Society of Canada.
What is dementia?
Dementia is not a disease, but a general term used to refer to disorders that cause progressive loss of cognitive functioning, which means it affects your way of thinking, remembering and reasoning. Many people who are diagnosed with dementia can also experience changes in their mood and personality.
More than 500,000 Canadians live with dementia or Alzheimer’s disease (a form of dementia). As our population ages, experts project the number of people living with some from of dementia to be as high as 930,000 by 2030.
What causes dementia?
Dementia results from a variety of diseases and injuries that primarily or secondarily affect the brain.
Are dementia and Alzheimer’s disease the same thing?
Although they are often used interchangeably, Alzheimer’s disease is the most common form of dementia. According to the World Health Organization saying it contributes to 60-70% of dementia cases. Many people use the terms “dementia” and “Alzheimer’s” interchangeably, but in reality Alzheimers is the cause and dementia is the effect.
Stroke, head injuries and even Parkinson’s disease are also causes of dementia.
What are common symptoms of dementia?
According to experts, the most common symptom of dementia is short-term memory loss. This includes forgetting something that happened or was said within the last 10-15 minutes, repeating oneself and asking the same questions.
Dr. Andrew Frank, a cognitive neurologist at the Bruyere Memory Program at Ottawa’s Elisabeth Bruyere Hospital, lists other symptoms as deterioration in language, words and judgement.
The odd forgetfulness of a word or name that comes back to you later is normal, especially as we age or if we are stressed or sleep deprived. It’s when the memories are not coming back at all that’s a signal of a much deeper problem.
“One of the rules of thumb is that if you’re realizing your own memory problem, that’s a good sign because you’re remembering you’re forgetting,” Frank explains in an interview with Yahoo Canada. “It’s more serious if you are not realizing that you’re forgetting, meaning you’re forgetting that you’re forgetting and that can be a sign of something more serious like dementia.”
What to do if you suspect your family member is showing symptoms of dementia
If you notice a change in a family member’s ability to recall information, repeating themselves, becoming confused, struggling with their vocabulary or completing tasks that would otherwise seem easy (like shopping or driving to a familiar location), consider accompanying them to an appointment with their family doctor as soon as possible.
A doctor can perform memory tests and others to measure blood pressure and check levels of various chemicals, hormones and vitamins in the body. The family physician can refer the patient to a memory clinic as well, where more testing can be done to determine if the diagnosis is dementia.
Who is the most at risk of developing dementia?
When it comes to dementia there are some risks that we can and can’t control.
Factors that we can’t control that increase our risk of developing dementia are age (one in 20 Canadians over 65 have Alzheimer’s disease), genetics and sex; women have a greater chance of developing dementia than men.
The good news is that there are things we can control that can help minimize our risk of developing dementia. Maintaining a healthy lifestyle and diet are both recommended. Making sure you’re physically active everyday is important and Frank insists exercising your brain is equally as crucial through hobbies and puzzles.
