A healthy diet, physical activity and brain exercises can help slow mental decline in older people at risk fordementia, a new study suggests.
On the other hand, a high body-mass index (BMI) and poor heart health are significant risk factors for age-related dementia, the researchers said. BMI is an estimate of body fat based on height and weight.
The study included 1,260 people in Finland, aged 60 to 77, who were considered to be at high risk for dementia. They were randomly selected to receive either regular health advice (the control group) or to be part of an intervention group.
