Dementia in Elderly

The term ‘dementia’ is an umbrella term that encompasses age associated cognitive impairment. Commonly incorrectly associated with ‘senility’, dementia is sometimes seen as a normal part of aging. However, dementia is a more serious form of mental deterioration that is not a normal part of aging.

In Singapore, 1 in 10 seniors above the age of 60 years old has dementia. 

Dementia can affect adults of any age, but it is more common in those aged 65 and above. In 2012, there are 28,000 people aged 60 years and above with dementia. By 2030, there will be over 150,000 persons with dementia. This makes it critical for us to learn more about dementia and how to take care of elderly with dementia.

What causes dementia?

Dementia is caused by damage to or loss of nerve cells and their connections in the brain. The location of the damage affects the symptoms exhibited by each individual.

Health and lifestyle are possible factors that will affect our chances of developing dementia.

Common causes of dementia are: 

  1. Alzheimer’s disease. This is the most common cause of dementia.
