Dementia is a syndrome consisting of a number of symptoms that include loss of memory, judgment and reasoning, and changes in mood and behaviour. These symptoms may affect a person's ability to function at work, in social relationships or in day-to-day activities. Sometimes dementia-like symptoms can be caused by conditions that may be treatable, such as depression, thyroid disease, infections or drug interactions. If the symptoms are not treatable and progress over time, they may be due to damage to the nerve cells in the brain. A person should seek a thorough medical assessment if any of these symptoms are present.
Alzheimer's disease, the most common form of dementia, accounts for 64 per cent of all dementias in Canada. The features of Alzheimer's disease include a gradual onset and continuing decline of memory, as well as changes in judgment or reasoning, and the inability to perform familiar tasks. Sometimes a person may experience symptoms early on, such as sudden onset of memory loss, behaviour changes, or difficulties with speech and movement. These symptoms may suggest a dementia other than Alzheimer's disease.
Regardless of the type of dementia, individuals can obtain information and support from the Alzheimer Society of Calgary.
