Warning signs & symptoms Alzheimer's disease is a progressive,
degenerative disease. Symptoms include loss of memory,
difficulty with day-to-day tasks, and changes in mood and
behaviour. People may think these symptoms are part of normal
aging but they aren't. It is important to see a doctor when you
notice any of these symptoms as they may be due to other
conditions such as depression, drug interactions or an
infection. If the diagnosis is Alzheimer's disease or other
dementia, your local Alzheimer Society can help. Last Updated:
