Dementia is a condition that causes progressive intellectual decline leading to increasing difficulties in coping with everyday activities. It is not a part of normal aging.
Who is Affected?
It affects mainly elderly people. Locally, according to the Well-being of the Singapore Elderly (WiSE) study led by the Institute of Mental Health in 2015, one in 10 people aged 60 and above may have dementia. This translates to almost 82,000 people in 2018 and the number is expected to exceed 100,000 in a few years’ time. Read more here.
Types of Dementia
Dementia is an umbrella term that describes a wide range of symptoms including memory loss and mental decline.
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.
Symptoms of Dementia
Generally, there are three stages which mark the onset and progression of the disease.
The individual appears forgetful or occasionally repeats himself. Sometimes they behave oddly and become withdrawn, lethargic or agitated. Planning of day-to-day activities becomes difficult.
In this stage, the changes become more noticeable. The memory lapses are more obvious. Behaviour becomes problematic and may interfere with normal day-to-day activities. Some examples of behaviour which may be symptomatic of moderate dementia are:
- Wandering and getting lost
- Repeating words
- Neglecting personal hygiene
- Losing track of time and events
- Forgetting the names of common objects and familiar people
- Irritability and agitation
The individual is unable to recognise family members and will need help in personal care such as bathing, going to the bathroom, dressing and eating. Their speech may be difficult to understand and they may not comprehend what is being said to them.
Below is a checklist of symptoms of dementia:
- Problems with recent memory

- Changes in mood, behaviour & personality
- Withdrawal from hobbies & activities
- Misplacing things
- Confused with places and time
- Difficulties in planning and thinking
