What is it about?
Large household provides more biological, psychological and social health protection for preventing the residents from dying of dementia. These protecting effects are independent of the common major dementia associated factors, such as ageing, economic affluence and urban advantages.

Why is it important?
Dementia produces an increasing societal burden resulting in a total economic cost of US$ 818 billion (1.1% of the world’s gross domestic product). However, the aetiology of dementia remains vague, let alone the treatment. Large household has shown its consistent and significant protection against dementia deaths. This may be an alternative for preventing and treating dementia.
Perspectives
As part of dementia prevention, healthcare practitioners should encourage people to increase their positive interactions with persons from their neighbourhood or other fields where large household/family size is hard to achieve.
