Physical activity together for couples living with mild cognitive impairment (PAT-MCI): A feasibility study.

Mild cognitive impairment is a prodromal phase of Alzheimer's disease and related dementias. Cognitive and/or neuropsychiatric symptoms that could worsen over time cause challenges for patients and romantic partners, who often assume the role of informal caregivers. Although physical activity is beneficial, older adults with mild cognitive impairment and their romantic care partners are generally physically inactive. Our 16-week study was performed to see whether physical activity together is feasible to increase physical activity among four dyads (individuals with mild cognitive impairment and their spouses). Our dyadic intervention was feasible given more than 70 % of participants self-reported adherence to physical activity based on the guidelines for adults in the United States. In exit interviews, togetherness was highlighted as one of the biggest strengths of this study. Future studies with more representative samples are needed, as well as adopting a more tailored approach that accounts for individuals' levels of physical fitness.

The Effects of Multi-Domain Interventions on Cognition: A Systematic Review.

This review aimed to evaluate the effects of multi-domain interventions on cognition among individuals without dementia. Multi-domain interventions refer to those combining any single preventive measure such as physical activity, cognitive training, and/or nutrition to prevent dementia. Seventeen studies were included (n = 10,056 total participants; mean age = 73 years), eight of which were rated as strong in quality while the other nine showed moderate quality. The standardized mean difference (SMD; d) was used to calculate the effect size for each included study. Multi-domain interventions consisting of physical activity, cognitive training, cardioprotective nutrition, and/or cardiovascular health education exerted beneficial effects on global cognition, episodic memory, and/or executive function with very small to moderate effect sizes (0.16-0.77). Nurses may consider combining these components to potentially stave off dementia. Future research is warranted to identify the optimal multi-domain intervention components that can induce clinically significant beneficial effects on cognition.

Brief report: patient cognitive status and the identification and management of depression by primary care physicians.

OBJECTIVES: No known study has examined the role of patients' cognitive impairment in the identification and management of depression by primary care physicians. DESIGN: A cross-sectional survey conducted between 2001 and 2003. PARTICIPANTS: A sample of 330 adults aged 65 and older from Maryland primary care practices with complete information on cognitive and psychological status, and physician assessments. MEASUREMENTS: Primary care physicians were asked to rate cognition and depression on a Likert scale, as well as report management of depression within 6 months of the index visit. Patient interviews included standardized measures of psychological and cognitive status. RESULTS: Older adults identified as depressed by their physician were more likely to be identified as cognitively impaired (unadjusted odds ratio [OR] = 3.71, [95% confidence interval] [CI] [1.93, 7.16]). Older adults identified as cognitively impaired had a tendency to be managed for depression (unadjusted OR = 2.62, 95% CI [0.96, 7.19]). In adjusted multivariate models, these associations remained unchanged. CONCLUSIONS: When physicians identified a patient as cognitively impaired, they were more likely to identify the patient as depressed and to report treatment of the depression. An understanding of how physicians think about depression in the context of cognitive impairment is important for designing depression interventions for older adults.

Respecting end-of-life treatment preferences.

Most patients eventually must face the process of planning for their future medical care. However, few Americans have a living will or a durable power of attorney for health care. Although advance directives provide a legal basis for physicians to carry out treatment using a health care proxy or a living will, they also should reflect the patient's values and preferences. Family physicians are in a position to integrate medical knowledge, individual values, and cultural influences into end-of-life care. Family physicians can best respect the autonomy of patients by allowing the patient and family to prospectively identify relevant health care preferences, by sustaining an ongoing discussion about end-of-life preferences, and by abiding by the decisions their patients have made.
