One's experience with dementia may affect their perceptions about dementia preventability, which in turn could influence preventive health behaviors. We aimed to examine how having a family history of dementia and caregiving experience are associated with perceptions about and self-efficacy for dementia preventability. Cross-sectional, self-administered survey. Participants reported whether they have had a family member with dementia and, among those who reported having a family member with dementia, whether they served as a caregiver. Outcomes were perceptions about the likelihood of dementia preventability, self-efficacy for dementia prevention, and benefits of specific dementia prevention strategies. Associations were assessed via partial proportional odds model for ordinal outcome variables and logistic regression for binary outcome variables. Of 1,575 respondents, 71% had a family member with dementia, of which 42% served as a caregiver. People with a family member with dementia were less likely to believe that dementia is preventable (aOR = 0.75, 95% CI: 0.58, 0.96) and had lower self-efficacy for dementia prevention (aOR = 0.71, 95% CI: 0.56, 0.90). The subgroup analysis among those with caregiving experience was consistent with the primary findings, showing less belief in the likelihood of dementia preventability (aOR = 0.69, 95% CI: 0.46, 1.03) and self-efficacy (aOR = 0.75, 95% CI: 0.56, 1.00). Having a family member with dementia is associated with unfavorable perceptions about dementia preventability. Incorporating family history of dementia into communication efforts about dementia risk reduction may help address potential barriers to preventive health behaviors. [ABSTRACT FROM AUTHOR]

While data are accumulating on the association between neuropsychological performance and real-world endpoints, less is known about the association with medical self-management skills. The self-management of type 1 diabetes (T1D) is often complex, and mismanagement can result in hypoglycaemia and hyperglycaemia and associated morbidity and mortality. The T1D Exchange conducted a case-control study evaluating factors associated with severe hypoglycaemia in older adults (≥ 60 years old) with longstanding T1D (≥ 20 years). A battery of neuropsychological and functional assessments was administered, including measures of diabetes-specific self-management skill (diabetes numeracy) and instrumental activities of daily living (IADL). After adjusting for confounding variables, diabetes numeracy was related to memory and complex speeded attention; while IADL were associated with simple processing speed, executive functioning, complex speeded attention and dominant hand dexterity. The severity of overall cognitive deficit was uniquely associated with both diabetes numeracy and IADL, when controlling for age, education, frailty and depression. This study demonstrates that the cognitive deficits in older adults with T1D have functional implications for both diabetes management and IADL. Further research is needed to determine specific interventions to maximise diabetes self-management in older adults with declining cognition. [ABSTRACT FROM PUBLISHER]
