Non-pharmacological strategies to delay cognitive decline

Non-pharmacological preventive strategies to delay cognitive decline have become the focus of recent research. This review aims to discuss evidence supporting the use of physical and cognitive activity to reduce the risk of cognitive decline and dementia in later life. Both strategies are associated with better cognitive health in older adults. This positive effect seems stronger for middle-aged and older adults with normal cognition and less clear when cognitive impairment is present. Physical and cognitive activities have been linked to indirect and direct biological factors affecting brain health. Future research will need to explore details about type, intensity, duration and combination of interventions. An important aim is standardization between studies, as well as evidence of improved clinical outcomes and cost-effectiveness. Identifying strategies that succeed at sustaining improved lifestyle is necessary, and the use of modern technology could play a crucial role in this regard. In the meantime advice on physical and cognitive activities should be included when health advice is given to middle-aged and older adults.
