Lecanemab became the first disease-modifying treatment for Alzheimer disease (AD) to receive traditional approval by the US Food and Drug Administration in 2023. Although the monoclonal antibody can remove amyloid-β plaques, the drug has been linked to brain changes known as amyloid-related imaging abnormalities (ARIA). A new study of patients with early symptomatic AD treated at an outpatient memory clinic suggests these and other adverse events are manageable in this population.

Poetry catalyzes memory, as other poems featured in JAMA have variously demonstrated. It is used directly among patients with dementia in programs such as the Alzheimer’s Poetry Project to reproducibly beneficial effect. “Missing Father” offers another example of the connections between poetry and memory. The poem both describes actual memories while at the same time seeming to spark more of them. The paradoxical double meaning of the title both reports on and grieves for the lost voice of the storyteller father—he is both absent and an actively yearned-for presence—while the first line’s immediacy of “this morning being” ironically unleashes vivid memories, from the sound of his voice “rising/from the worn pages” of a picture book to the uncanny word-picture of the speaker and her twin sister eagerly awaiting his return from work, “pajamas hanging on us/like wilted petunias.” The poem reanimates them all together as they chant the names of the book’s characters, simultaneously recalling both the tenderness of a distant childhood and enacting poetry’s mooted origins in the passing down of community wisdom through incantatory language. Yet even as poetry facilitates such recollection, and helps sustain the more practical, trying search for “nursing homes close and affordable,” ultimately it cannot bring back the long-gone, stricken father; instead, it becomes an act of healing, remembering that brighter time of more bearable loss, “a day when the only problem/was a carrot missing from/Mister McGregor’s garden.”

Introduction
There is a need for early, non-invasive and inexpensive biomarkers for Alzheimer’s disease (AD), which could serve as a proxy measure in prevention and intervention trials that might eventually be suitable for mass screening. People with Down syndrome (DS) are the largest patient group whose condition is associated with a genetically determined increased risk of AD. The REVEAL study aims to examine changes in the structure and function of the eye in individuals with DS compared with those with mild cognitive impairment (MCI) and cognitively healthy control (HC) individuals. REVEAL will also explore whether these changes are connected to inflammatory markers previously associated with AD.

Methods and analysis
The protocol describes a cross-sectional, non-interventional, single-centre study recruiting three cohorts, including (1) participants with DS (target n=50; age range, 6–60 years), (2) participants with MCI (target n=50; age range, 50–80 years) and (3) HC participants (target n=50; age range, 50–80 years). The primary research objective is to profile retinal, choroidal and lenticular status using a variety of eye imaging modalities and retinal functional testing to determine potential associations with cognitive status. The REVEAL study will also measure and compare established blood markers for AD and proteomic and transcriptomic marker profiles between DS, MCI and HC groups. Between-group differences will be assessed with an independent sample t-test and 2 tests for normally distributed or binary measures, respectively. Multivariate regression analysis will be used to analyse parameters across all three cohorts. Data collection began in October 2023 and is expected to end in October 2025.

Ethics and dissemination
The study gained a favourable opinion from Health and Social Care Research Ethics Committee A (REC reference 22/NI/0158; approved on 2 December 2022; Amendment 22/0064 Amend 1, 5 April 2023; Amendment 22/0064 Amend 2; 23 May 2024; Amendment 22/0064 Amend 3; 25 June 2024; Amendment 22/0064 Amend 4; 16 January 2025; Amendment 22.0064 Amend 5; 9 May 2025; Amendment 22.0064 Amend 6; 9 June 2025). The study has also been reviewed and approved by the School of Biomedical Sciences Research Ethics Filter Committee within Ulster University. Findings from the REVEAL study will be presented to academic audiences at international conferences and peer-reviewed publications in targeted high-impact journals after data collection and analysis are complete. Dissemination activities will also include presentations at public events.

This Special Communication presents a framework for using a cross-species behavioral neuroscience approach to study emotional well-being and brain aging in the context of Alzheimer disease and related dementias.

This Viewpoint examines the use of blood-based biomarkers to test for Alzheimer disease and outlines why they should not be the first or only tool used in screening for cognitive impairment.

Buildup of the protein amyloid β (Aβ) in the brain can predict Alzheimer disease years before symptoms appear. Although learning about the risk may relieve some anxiety, a new study suggests that it lessens individuals’ motivation to maintain a healthy lifestyle.

Delirium affects one-third of hospitalized older adults and is associated with prolonged length of stay, institutional discharge, long-term functional and cognitive decline, Alzheimer disease and related dementias (AD/ADRD), and death. Moreover, the costs of delirium exceed $182 billion annually in the US alone. Despite these compelling data, accurate identification of delirium remains challenging, with more than half of delirium going unrecognized in routine care. While delirium prevention has advanced substantially, delirium treatment, which relies on early and accurate identification, lags. More than 40 tools are available for delirium assessment, ranging from short structured screens to in-depth reference standards. Evidence on how to implement these tools to improve delirium identification at the bedside, including which tool to use, who should administer it, how often, and how to educate and engage the care team, remains limited.

Introduction
Cognitive frailty (CF) is a clinical syndrome characterised by the concurrent occurrence of physical frailty and cognitive impairment, excluding Alzheimer’s disease and other forms of dementia. Recent studies have shown that combining aerobic exercise (AE) and meditation (ME) effectively enhances both physical and cognitive functions in individuals with CF. The study aims to determine whether the combined application of AE and ME can elicit significantly greater improvements in physical and cognitive functions among individuals with CF compared with the independent practice of either AE or ME alone.

Methods and analysis
The research design employs a four-arm, assessor-blind randomised controlled trial. A total of 140 qualified subjects will be randomly allocated among four groups: AE, ME, AE combined with ME and a health education control group, ensuring equivalent distribution across groups. The intervention phase of the study will last for 12 weeks. The primary outcomes will include the Edmonton Frailty Scale, while secondary outcomes will encompass evaluations of cognitive functions (including global cognitive function, memory, attention, executive function and visuospatial abilities), physical performance (measured by gait speed and lower extremity strength), subjective experiences (such as fatigue, quality of life, mindfulness, mood and sleep quality), as well as structural and functional MRI assessments and serum biomarkers. Outcomes will be evaluated at baseline and following the 12-week intervention.

Ethics and dissemination
The Ethics Committee of the Affiliated Rehabilitation Hospital of the Fujian University of Traditional Chinese Medicine granted ethical approval for the study (2023KY-012–02). The findings will be disseminated through publications in peer-reviewed journals and presentations at academic conferences.
