Alzheimer's disease

Alzheimer's disease is the most common form of dementia. It accounts for 64 per cent of all dementias in Canada. Alzheimer's disease causes a gradual (slow) onset of memory loss that affects the person's ability to function on a day-to-day basis, and a continuing decline. There are also changes in judgment and reasoning, and performing familiar, everyday tasks becomes harder.

Sometimes a person may have symptoms such as sudden onset of memory loss, early behaviour changes, or difficulties with speech and movement. These symptoms may suggest that the problem is not Alzheimer’s disease, but another type of dementia.
