ABSTRACT

OBJECTIVES: To examine the influence of sociodemographic factors on employment changes among adult children following onset of parental Alzheimer's disease and related dementia (ADRD). METHODS: We used Health and Retirement Study (2010-2018; N = 20,110) data to examine adult child (ages 50-70) changes in employment and work hours at onset of parental ADRD and potential variation by gender, age, race, ethnicity, and education. RESULTS: Parental ADRD onset was not associated with changes in adult child employment overall, although associations differed substantially across subpopulations defined by education level. Sons with the lowest education were least likely to cease employment, while daughters with the lowest education were most likely to reduce work hours. Sons at older ages were increasingly likely to reduce work hours or end employment following parental ADRD onset. DISCUSSION: The potential impact of parental ADRD on adult child employment is complex and should be considered in the context of sociodemographic factors.

ABSTRACT

Recruitment registries are novel tools to accelerate Alzheimer disease research accrual. Optimal methods to populate such registries remain largely unstudied. We sent postcards with 3 unique taglines (Alzheimer's Prevention Research, brain health research, general research) to 100,000 local residents aged 50 years and older to assess the effectiveness of recruiting to an online recruitment registry by mail. The postcard campaign recruited 273 new registry enrollees (0.27% overall response rate). Neither the response rate nor the demographic characteristics of recruited participants differed by the postcard tagline. These results suggest that direct mail may not be the most cost-effective approach to recruit participants to online registries.

ABSTRACT

INTRODUCTION: The apolipoprotein E (APOE) gene is the strongest known genetic risk factor for sporadic Alzheimer disease (AD). APOE can be used as an enrichment strategy or inclusion criterion for AD prevention trials. Personal genomics companies market direct-to-consumer (DTC) genetic tests, including APOE. We assessed DTC APOE testing usage among enrollees of the University of California Irvine Consent-to-Contact Registry, an online recruitment registry, and attitudes toward using this information in clinical trial recruitment. METHODS: We emailed links to an electronic survey to registry enrollees age 50 years or older. We assessed participants' use of DTC services, willingness to learn APOE status, and willingness to share genetic information. Logistic regression models assessed relationships between DTC testing usage and demographic characteristics, and with willingness to share results to assist trial recruitment. RESULTS: Among 1312 responders (57% response rate), few (7%) had used DTC testing for APOE. Non-Hispanic Asian enrollees were 93% less likely to have used DTC testing, compared with non-Hispanic Whites [95% confidence interval: (0.01, 0.67)]. Willingness to share APOE information for study recruitment was >90% for both users and nonusers. CONCLUSIONS: Matching participants to trials on the basis of DTC APOE information may be an effective way to streamline AD prevention trial recruitment.

ABSTRACT

Reluctance to undergo lumbar puncture (LP) is a barrier to neurological disease biomarker research. We assessed whether an educational intervention increased willingness to consider research LP and whether message framing modified intervention effectiveness. We randomly assigned 851 recruitment registry enrollees who had previously indicated they were unwilling to be contacted about studies requiring LP to gain or loss framed video educational interventions describing the procedure and the probability of experiencing adverse events. The gain framed intervention emphasized the proportion of individuals free of adverse events; the loss frame emphasized the proportion experiencing adverse events. The primary outcome for the study was the participant's post-intervention agreement to be contacted about studies requiring LP. Participants were mean (SD) age 60.1 years (15.7), 69% female (n = 591), and mostly college educated and white. Among the 699 participants who completed the study, 43% (95% CI: 0.39, 0.47; n = 301) changed their response to agree to be contacted about studies requiring LP. We estimated that participants randomized to the gain framed intervention had 67% higher odds of changing their response compared to those randomized to the loss frame (Odds Ratio = 1.67; 95% CI: 1.24, 2.26; p < 0.001). A classification and regression tree model identified participants' pre-intervention willingness as the strongest predictor of changing response. Education, in particular education that alerts participants to the probability of not experiencing adverse events, may be an effective tool to increase participation rates in research requiring LP.

ABSTRACT

OBJECTIVE: All Alzheimer disease (AD) clinical trials, including those enrolling patients with mild cognitive impairment (MCI), require dyadic participation. The purpose of this study was to elucidate how people with MCI and their study partners decide whether to enroll in clinical trials. METHODS: This was a mixed methods interview study. We interviewed patient participants with a consensus research diagnosis of MCI and their study partners. Interviews examined how dyads decide whether to enroll in a clinical trial and whether AD biomarker testing affects willingness to enroll. RESULTS: Though most MCI patients and study partners would decide in partnership whether to enroll in a clinical trial, agreement was lower among nonspousal, compared with spousal, dyads. Deterrents to enrollment included concerns about patient safety and inconvenience, especially for study partners. Motivators to enrollment included altruism, the desire to contribute to research, hope for patient benefit, and the desire to learn more about the patient's condition. When asked open-ended questions about motivators to enroll in trials, few patients cited access to biomarker testing specifically, though most expressed a desire to undergo biomarker testing when asked directly. CONCLUSION: Spousal and nonspousal MCI dyads may approach clinical trial decisions differently. Future research should investigate how AD biomarker testing affects participants' willingness to enroll in trials.

ABSTRACT

BACKGROUND: The experiences of biomarker-ineligible cognitively normal persons can inform trial conduct and the translation of preclinical Alzheimer's disease (AD) into clinical practice. METHODS: We interviewed 33 persons whose "not elevated" brain amyloid imaging biomarker result made them ineligible for a preclinical AD trial. RESULTS: Most participants (n = 17) reported being informed that they did not demonstrate adequately elevated amyloid to qualify, whereas some (n = 14) reported being told they had no amyloid or plaques. Relief (n = 17) and disappointment related to not being able to participate (n = 12) were the most common reactions to results. Nearly all participants would have made healthy lifestyle changes if they had received an "elevated" result, would have another scan, and would participate in another AD prevention trial. CONCLUSIONS: Although some participants may misconstrue results, disclosure of a "not elevated" amyloid result in the research setting causes little behavior change; willingness to participate in AD research remains.

ABSTRACT

Potential participant registries are tools to address the challenge of slow recruitment to clinical research. In particular, registries may aid recruitment to secondary prevention clinical trials for Alzheimer's disease (AD), which enroll cognitively normal older individuals meeting specific genetic or biomarker criteria. Evidence of registry effectiveness is sparse, as is guidance on optimal designs or methods of conduct. We report our experiences of developing a novel local potential participant registry that implemented online enrollment and data collection. In the first year of operation, 957 individuals submitted email addresses to the registry, of whom 592 self-reported demographic, family history, and medical data. In addition, registrants provided information related to their interest and willingness to be contacted about studies. Local earned media and community education were the most effective methods of recruitment into the registry. Seventy-six (26%) of 298 registrants contacted about studies in the first year enrolled in those studies. One hundred twenty-nine registrants were invited to enroll in a preclinical AD trial, of whom 25 (18%) screened and 6 were randomized. These results indicate that registries can aid recruitment and provide needed guidance for investigators initiating new local registries.

ABSTRACT

BACKGROUND: Mild cognitive impairment (MCI) has an uncertain etiology and prognosis and may be challenging for clinicians to discuss with patients and families. Amyloid imaging may aid specialists in determining MCI etiology and prognosis, but creates novel challenges related to disease labeling. METHODS: We convened a workgroup to formulate recommendations for clinicians providing care to MCI patients. RESULTS: Clinicians should use the MCI diagnosis to validate patient and family concerns and educate them that the patient's cognitive impairment is not normal for his or her age and education level. The MCI diagnosis should not be used to avoid delivering a diagnosis of dementia. For patients who meet Appropriate Use Criteria after standard-of-care clinical workup, amyloid imaging may position specialists to offer more information about etiology and prognosis. Clinicians must set appropriate expectations, including ensuring that patients and families understand the limitations of amyloid imaging. Communication of negative results should include that patients remain at elevated risk for dementia and that negative scans do not indicate a specific diagnosis or signify brain health. Positive amyloid imaging results should elicit further monitoring and conversations about appropriate advance planning. Clinicians should offer written summaries, including referral to appropriate social services. CONCLUSIONS: In patients with MCI, there is a need to devote considerable time and attention to patient education and shared decision-making. Amyloid imaging may be a tool to aid clinicians. Careful management of patient expectations and communication of scan results will be critical to the appropriate use of amyloid imaging information.

ABSTRACT

INTRODUCTION: Amyloid imaging is a tool that has recently become available to dementia specialists evaluating patients with possible Alzheimer's disease. Studies have assessed the impact of amyloid imaging on diagnostic and treatment decisions, but patient and family perspectives have received less attention. METHODS: To examine how amyloid imaging affects the diagnostic experience of patients and families, we interviewed members of 26 patient-caregiver dyads with whom a neurologist discussed the option of amyloid positron emission tomography. RESULTS: Most participants who chose to undergo amyloid imaging would choose to do so again. Regardless of the scan outcome, patients and caregivers commonly expressed relief on learning the scan results. Some participants expressed expectations that were beyond scan capabilities. DISCUSSION: Amyloid imaging may provide information that patients and their families find useful. Clinicians must set correct expectations and ensure that families understand the limitations of amyloid imaging.
