The Alzheimer Society of Canada predicts a significant increase in the number of people living with dementia in the country by 2050. However, there is hope as the first-ever disease-modifying drugs are being tested in major clinical prevention trials. This article provides answers to frequently asked questions about Alzheimer's disease.
The Alzheimer Society of Canada predicts there will be more than 1.7 million people in Canada living with dementia in 2050, nearly three times the estimated 650,000 today.
What’s the difference between Alzheimer’s and dementia? Alzheimer’s is the most common form of dementia, which is an umbrella term for more than 50 brain diseases and conditions that affect memory and thinking. The terms are not interchangeable. Though fewer than five per cent of Alzheimer’s cases are caused by deterministic genes that run in families – referred to as familial or inherited Alzheimer’s – people who have a parent with Alzheimer’s are at an elevated risk of developing the disease.
Today, amyloid plaques and tau tangles can be confirmed using a PET scan or by testing cerebrospinal fluid obtained through a lumbar puncture. Canadian doctors, however, don’t routinely use PET scans or spinal taps for diagnosis because there’s little point in confirming the presence of amyloid when there aren’t any authorized anti-amyloid medications yet available here.
