About Alzheimer's & Dementia
What is the difference between Alzheimer’s disease and dementia?
“Dementia” is not a single disease. It refers to a general decline in mental abilities overall and could be caused by a number of different conditions or diseases. The term “dementia” describes a group of symptoms including loss of memory, judgment and reasoning as well as changes in mood, behaviour and communication abilities. These changes are significant enough to cause difficulty in a person’s day-to-day functioning, with at least 2 of the core symptoms present.
Alzheimer ’s disease is simply the most common type of dementia.
It accounts for over 64% of all cases of dementia. Vascular dementia is the next most common type.
Alzheimer’s disease is a physical, progressive and degenerative disease of the brain characterized by memory loss, communication difficulties, disorientation regarding time and place and changes in personality and behaviour. Each of these symptoms affects a person’s ability to function independently.
