Attitudes and Considerations for Multidomain Lifestyle Approaches to Dementia Prevention: A Qualitative Study.

Abstract

Dementia, with the most common form being Alzheimer's disease, is a global health issue and lifestyle-based strategies may reduce risk. Individuals with a family history of dementia are an important target group, but little is known about their attitudes and perceptions of dementia risk reduction. To elucidate the attitudes to and key considerations for multidomain lifestyle-based dementia prevention strategies in middle-aged Australians with a family history of dementia. Twenty participants (80% female; age range 47-65 years), undertook semi-structured phone-based interviews. Inductive thematic analysis of interview transcripts was conducted. Hierarchical coding frames and illustrative quotes were compiled and critically challenged until a final set of themes was produced. Some participants expressed a positive attitude toward lifestyle-based dementia prevention. Reasons related to wanting to future proof, believing that risk reduction is relevant at all life stages and/or that there is always room for improvement. Other participants had a negative attitude, expressing that they were already following a healthy lifestyle, did not feel it was relevant to them yet, and/or held a deterministic view that dementia is random. Important considerations congregated on the themes of being tailored/personalized, taking a holistic approach, and involving small, achievable steps. In individuals with a family history of dementia, a positive attitude to dementia prevention holds promise for intervention efforts, but in individuals expressing negative attitudes, further education and individual-level counselling may be warranted. Multidomain lifestyle-based preventive strategies also need to be tailored to the needs of key target groups to optimize appeal and effectiveness.
