Dementia is an illness which affects the brain, causing the brain cells to die at a faster rate than normal. It is NOT normal ageing. As a result, the mental abilities of the person with dementia declines. This leads to failing memory, deterioration of intellectual function and personality changes.
Who is Affected?
It affects mainly elderly people. In Singapore, the prevalence rate of people with dementia aged 65 years and above is about 6.2%. See how Singaporeans are affected by dementia here.
Types of Dementia
Dementia is an umbrella term that describes a wide range of symptoms including memory loss and mental decline. In Singapore alone, some 82,000* people are affected by one form of dementia or another.
There are two common types of dementia: Alzheimer’s Disease and Vascular Dementia. In Alzheimer’s disease, the onset of symptoms and the progression of the illness is gradual. Although the cause is still unknown, present research suggests that there is a familial tendency and certain chemicals in the brain are lacking. As yet, there is no known medical cure for the disease. Vascular dementia results from a series of strokes in the brain and it is also known as post-stroke dementia.

Generally, there are three stages which mark the onset and progression of the disease.
