Cognitive decline slowed with healthy lifestyle.

A new study, published in the Lancet journal, has revealed that in older people at risk of dementia can be mitigated with healthy eating guidance, exercise, brain training, and management of metabolic and vascular .

The study led by the Karolinska Institutet in Stockholm, Sweden, and Welfare in Helsinki, and University of Eastern Finland examined the impact of a comprehensive intervention program on 1260 people from across Finland, aged 60-77 years. All of the were deemed to be at risk for age-related dementia. Half of the participants were randomly allocated to the intervention group and the other half were randomly allocated to a , who only received regular advice.

The intervention program consisted of regular meetings over two years with physicians, nurses, and other professionals, with participants given comprehensive advice on maintaining a , exercise programs including both muscle and cardiovascular training, brain training exercises, and management of metabolic and vascular through regular blood tests, and other means. The ’ mental function was scored using the Neuropsychological Test Battery where a higher score corresponds to better mental functioning.

Test scores in the intervention group were 25% higher than in the . Other parts of the test revealed a striking difference between groups. For executive functioning (the brain’s ability to organize and regulate thought processes) scores were 83% higher in the intervention group, and processing speed was 150% higher.
