Being laid back and sociable reduces risk of dementia

Published 19 January 2009

People who are easily stressed and less outgoing may have an increased risk of dementia, particularly if they are also socially isolated, according to new research.

(Published in Neurology on January 20.)

506 older people without dementia were followed for six years to see which personality types developed dementia. 144 of the participants developed dementia.

Alzheimer's Society comment:

'Doctors have always believed that personality traits are linked to risk of dementia. This compelling new evidence suggests people who are easily stressed or not very outgoing should make every effort to be socially active.

However, it's a chicken and egg scenario; do these personality traits increase risk of dementia in older people or are they an early sign of the disease? 1 in 3 people over 65 will die with dementia. It is vital to keep mentally and physically active throughout your life to reduce risk of this devastating condition'
