Alzheimer's preventable14th July 2014
According to research from the University of Cambridge, one in three cases of Alzheimer's disease worldwide is preventable through lifestyle changes.
The team analysed population-based data which suggested the onset of Alzheimer's can - in part - be linked to lifestyle choices, such as lack of exercise or smoking.
The research, published in the Lancet Neurology, corroborates with previous research from 2011, but disagrees to what extent lifestyle plays a part in the disease - reducing the risk from a half to a third - due to overlapping risk factors.
Alzheimer's Research UK said age was still the biggest risk factor.
Research suggested that reducing each risk factor by 10% could prevent nearly nine million cases of the disease by 2050.
Prof Carol Brayne, from the Institute of Public Health at the University of Cambridge, said: "Although there is no single way to treat dementia, we may be able to take steps to reduce our risk of developing dementia at older ages.
"Simply tackling physical inactivity, for example, will reduce levels of obesity, hypertension and diabetes, and prevent some people from developing dementia."
