A less healthy lifestyle increases the risk of dementia

The less healthy your lifestyle, the more you are at risk of developing dementia in later life, a new systematic review has shown. Researchers analysed the results of 18 studies with over 44,000 participants.

Having two or more 'modifiable risk factors', including smoking, high blood pressure, poor diet, inactivity, obesity and excessive alcohol consumption, puts adults at greater risk of developing dementia.

The included studies followed up people without signs of cognitive decline to see who developed dementia of any cause.

A third of the studies could be combined in a meta-analysis and these showed a 20% increase in the risk of dementia for one risk factor, which rose to 65% for two risk factors. The presence of three risk factors doubled the risk of dementia. Other individual studies were compatible with this pooled estimate.

These results are consistent with our growing knowledge of the links between unhealthy lifestyles and dementia.
