Screening and diagnosis
Alzheimer's disease and other dementia are progressive, degenerative diseases. Individuals or their family members may consult a family physician when they begin to notice symptoms such as loss of memory, judgment and reasoning, difficulty with day-to-day tasks and changes in communication abilities, mood and behaviour.
Cognitive impairment and dementia are present in about 20 per cent of the elderly population and are consistently rated among the top three concerns of older adults.1 Early detection of dementia provides an opportunity for the individual to adjust to the diagnosis and to participate actively in planning for the future.

Early diagnosis is important. Symptoms of irreversible dementia can be similar to those of other conditions such as depression, thyroid or heart disease, infections, drug interactions or alcohol abuse.
Finding out the cause of the symptoms can help people understand the source of the symptoms, get the proper care, treatment and support and plan for the future.
