Overview

Dementia currently affects more than 47 million people worldwide, its prevalence is forecasted to triple by 2050, and it has been reported to be one of the most costly disorders in Belgium. There is good scientific evidence that the cognitive impairments associated with the development of dementia can be lessened or even reversed thanks to the plasticity of the brain (rewiring). Recent research has shown that physical activity combined with performing cognitively challenging tasks is a very potent way to induce this rewiring of the brain, which can enable people to improve their cognitive functions. Yet, so far, these studies are mainly limited to controlled laboratory conditions. The investigators developed a real-life cognitively enriched walking program, with input from experts and end-users. In this study, the investigators will examine the added value of enriching physical activity (walking) with cognitive exercises in improving cognition of older adults by conducting a six-month community-based randomized controlled trial. The investigators will also examine the longer term effectiveness in a follow-up measurement visit six months after the program. The investigators will focus on the following outcomes: cognitive functioning (i.e., objective, subjective and cognitive activity), psychosocial wellbeing (i.e., loneliness, social support, depressive symptomatology, positive wellbeing and expectations regarding aging), physical activity (i.e. both objective and subjective) and general health.
