Treatment preferences reflect individuals' choice of therapy and influence their adherence to treatment and achievement of outcomes. The two-stage partially randomized clinical or preference trial (two-stage PRCT) is an appropriate design for examining the contribution of treatment preferences. It involves a two-stage process for assigning participants to treatments, which is useful to dismantle the effects of the treatments from those of treatment preferences. In this paper, we explain the role of treatment preferences in intervention evaluation research, describe the protocol for implementing the two-stage PRCT, and discuss issues in its application. The issues are encountered in the selection of treatments, assignment of participants and assessment of treatment preferences. Lastly, we propose ways to address the issues.

Preclinical Alzheimer's prevention trials require a multi-year commitment from diverse, cognitively unimpaired individuals willing to receive biomarker results of confirmed Alzheimer's pathology and possible ApoE4 status. Participants learn new terms such as ARIA, edema and microhemorrhage and undergo numerous MRI scans for safety monitoring. They take quarterly composite Alzheimer's assessments that are anxiety-provoking and highlight weaknesses which may have been unrecognized in daily life.

Background: The first disease-modifying treatments (DMTs) for Alzheimer's disease (AD) have been approved in the USA, marking profound changes in AD-diagnosis and treatment. This will bring new challenges in terms of clinician-patient communication. We aimed to collect the perspectives of memory clinic professionals regarding the most important topics to address and what (tools) would support professionals and their patients and care partners to engage in a meaningful conversation on whether (or not) to initiate treatment.

Previous work suggests that extracellular heat shock protein 90a (Hsp90a) mediates irisin-receptor interaction in bone and fat. Despite this, it remains unclear if Hsp90a is necessary for irisin signaling in the brain.

Background: Amid recent approvals, early Alzheimer's disease (AD) remains an active area of treatment development, but research on the utility of recruitment incentives in early AD trials remains limited. We examined how trial design features impact enrollment decisions among Mild Cognitive Impairment (MCI) patients and their family members.
Method: We performed a conjoint analysis experiment to compare early AD patients' preferences for trial features.

University College London, London, United Kingdom.
Background: The progressive nature of dementia and the complex needs means that people living with dementia require tailored approaches to address their changing care needs over time. These include physical multimorbidity, psychological, behavioural, and cognitive symptoms and possible risks arising from these and helping family caregivers. However, provision of these interventions is highly variable between and within countries, partly due to uncertainty about their efficacy and scarce resources.
