A combination of healthy eating, exercise, and brain-training program would result in slower mental decline among older people.

Two years later, the study participants’ mental function was scored using the Neuropsychological Test Battery (NTB), where a higher score corresponds to better mental functioning. It was seen that the overall test score in the intervention group was 25% higher than in the control group. For some parts of the test, the difference between the two groups was even more striking. Executive functioning was 83% higher and processing speed was 150% higher in the intervention group.
Prof Miia Kivipelto, author of the study, said "Our study is the first large randomized controlled trial to show that an intensive program aimed at addressing these risk factors might be able to prevent cognitive decline in elderly people who are at risk of dementia."
The study has been published in The Lancet.
