Multidomain Interventions for Cognitive Decline Prevention
Summary
Multidomain interventions aim to prevent or delay cognitive decline by simultaneously addressing a range of modifiable risk factors through combined lifestyle, behavioural and clinical strategies. Late-life dementia arises from complex interactions of vascular and neurodegenerative processes, suggesting that isolated approaches may fall short. Landmark trials have demonstrated that integrating tailored dietary advice, structured physical exercise, cognitive training, vascular risk monitoring and psychosocial support can preserve cognitive function in at-risk older adults. These interventions seek to enhance neuroplasticity and build cognitive reserve, thereby increasing resilience to neuropathology. The original Finnish FINGER study provided proof of concept, and subsequent efforts have focused on adapting and scaling the model across diverse populations. Key challenges include accurate risk stratification to identify individuals most likely to benefit, effective communication of risk, sustained adherence to multifaceted programmes and integration of digital tools to extend reach. Emerging clinical pathways propose dedicated services offering systematic risk profiling, personalised prevention plans and ongoing support. Collectively, this body of work underscores the global potential of multidomain prevention to mitigate the societal burden of dementia through practical, evidence-based strategies.

Technical terms
Multidomain intervention: An approach that combines two or more lifestyle, behavioural or medical strategies to address multiple risk factors for cognitive decline simultaneously.
Cognitive reserve: The brain’s capacity to withstand pathological damage, enhanced by factors such as education, mentally stimulating activities and social engagement.
Risk stratification: The process of categorising individuals by their likelihood of future cognitive decline based on genetic, clinical and lifestyle profiles.
Precision prevention: Tailored intervention strategies designed to match the specific characteristics and risk profiles of individuals or subgroups most likely to benefit.
Brain Health Service: A dedicated clinical pathway offering systematic risk profiling, risk communication, personalised multidomain prevention plans and cognitive enhancement support to cognitively unimpaired individuals.
