What is Alzheimer's Disease Alzheimer's disease is a progressive, neurodegenerative disorder that breaks down and destroys nerve cells in the brain.  As the disease progresses it affects one's ability to think, remember, and reason.  In addition to these losses, Alzheimer's disease creates changes in personality, mood, and behaviour. Alzheimer's is the most common form of dementia, or what we used to call senility.  Dementia is not a disease in itself, but rather a group of symptoms that result in a loss of intellectual functions. The specific cause of Alzheimer's disease remains unknown, however, certain risk factors such as age and family history have been associated with the disease.  Most people diagnosed with Alzheimer's disease are over 65, but the disease can occur earlier in life. There is no known cause or cure for this devastating disease but researchers around the world are working to find the answers. For now, medication can help treat some of the symptoms. Support services and education can enhance quality of life for people with the disease and their caregivers. Who has Alzheimer's? More than a quarter million people in Canada have Alzheimer's disease. 1 in 11 over the age of 65 has the disease and 1 in 2 over the age of 85 has the disease. As the post-Second World War "baby boom" generation ages, the incidence of Alzheimers disease is expected to skyrocket. Is it Alzheimer's Disease?
