The need for personalization when sharing results of amyloid imaging for Alzheimer's disease: Insights from a randomized experimental study.

Objective: To study information needs after receiving abnormal amyloid-PET results, and how individual characteristics moderate effects of different communication strategies on information recall.

Methods: In an online video-vignette experiment, seven vignettes each depicted a consultation of a physician sharing abnormal amyloid-PET results with a patient with Mild Cognitive Impairment(MCI), using different communication strategies. Healthy individuals (N = 1017; age 64 ± 8, 808(79 %) female), instructed to imagine themselves as the video-patient, viewed a randomly-assigned vignette and completed questionnaires to assess information needs and test moderation effects of gender, age, care-partner experience, health literacy, and coping.

Amyloid PET disclosure in subjective cognitive decline: Patient experiences over time.

Introduction: We disclosed amyloid positron emission tomography (PET) results in individuals with subjective cognitive decline (SCD) and studied patient experiences and outcomes over a 6-month period.

Methods: Fifty-seven participants from the Subjective Cognitive Impairment Cohort (SCIENCe) (66 ± 8 years, 21 [37%] F, Mini-Mental State Examination 29 ± 1, 15 [26%] amyloid positive [A+]) completed questionnaires 1 week prior (T0), 1 day after (T1), and 6 months after amyloid PET disclosure (T2). Questionnaires addressed patient-reported experiences and outcomes.

Interest in genetic susceptibility testing and disclosure of AD dementia risk in cognitively normal adults: a survey study.

Background: Apolipoprotein-E (APOE) genetic testing for Alzheimer's disease is becoming more important as clinical trials are increasingly targeting individuals carrying APOE-ε4 alleles. Little is known about the interest in finding out one's genetic risk for Alzheimer's disease in the general population. Our objective was to examine this in a sample of cognitively normal (CN) adults within a population-based online research registry with the goal to implement APOE-ε4 status for trial recruitment.

Impact of sharing Alzheimer's disease biomarkers with individuals without dementia: A systematic review and meta-analysis of empirical data.

Introduction: We conducted a systematic literature review and meta-analysis of empirical evidence on expected and experienced implications of sharing Alzheimer's disease (AD) biomarker results with individuals without dementia.

Methods: PubMed, Embase, APA PsycInfo, and Web of Science Core Collection were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results from included studies were synthesized, and quantitative data on psychosocial impact were meta-analyzed using a random-effects model.

Identifying best practices for disclosure of amyloid imaging results: A randomized controlled trial.

Introduction: Empirical studies on effective communication for amyloid disclosure in mild cognitive impairment (MCI) are lacking. We aimed to study the impact of six communication strategies.

Method: We performed a randomized controlled trial with seven randomly assigned, video-vignette conditions: six emphasizing a communication strategy and one basic condition.

Considerations regarding a diagnosis of Alzheimer's disease before dementia: a systematic review.

Background: The NIA-AA research framework proposes a purely biological definition of Alzheimer's disease (AD). This implies that AD can be diagnosed based on biomarker abnormalities, irrespective of clinical manifestation. While this brings opportunities, it also raises challenges.

Dementia risk communication. A user manual for Brain Health Services-part 3 of 6.

Growing evidence suggests dementia incidence can be reduced through prevention programs targeting risk factors. To accelerate the implementation of such prevention programs, a new generation of brain health services (BHS) is envisioned, involving risk profiling, risk communication, risk reduction, and cognitive enhancement. The purpose of risk communication is to enable individuals at risk to make informed decisions and take action to protect themselves and is thus a crucial step in tailored prevention strategies of the dementia incidence.
