Background: Identifying strategies to engage with potential participants is critical for efficient enrollment in Alzheimer's Disease (AD) trials. Previous studies link faster speed of first contact with successful phone interview completion for Major Depressive Disorder (MDD) participants. This has not been examined in AD participants.

The Alzheimer's Disease Cooperative Study Activities of Daily Living (ADCS-ADL) scale is frequently used to assess changes in both basic and instrumental activities of daily living, but there is no clear consensus on what magnitude of change on this scale may be considered clinically meaningful. To address this question, we conducted anchor-based analyses (as recommended by the FDA) to explore meaningful within-patient/participant change thresholds on the ADCS-ADL.

Background: Elevation of cerebrospinal fluid (CSF) tau is a feature of Alzheimer's disease (AD) and is being explored as a biomarker of AD and other tauopathies. The aim of this study was to elucidate the in vivo effects of DA-7503, a potent and selective tau aggregation inhibitor, and its pharmacodynamics on CSF tau in transgenic mouse models of Alzheimer's disease and primary tauopathies.
Method: TauP301L-BiFC mice expressing full-length human tau with the P301L mutation were orally administrated with DA-7503 for 1 month.
Background: Lecanemab is a humanized IgG1 monoclonal antibody binding with high affinity to protofibrils of amyloid-beta (Aβ) protein. In clinical studies, lecanemab has been shown to reduce markers of amyloid in early symptomatic Alzheimer's disease (AD) and slow decline on clinical endpoints of cognition and function. Herein, a modeling approach was used to correlate amyloid reduction with change in rate of AD progression.

Alzheimers Dement

Background: Within the dementia space, many caregivers lack understanding of hospice care and may not be well prepared for transition to hospice. Nonetheless, few studies have explored hospice transition specifically from the perspective of caregivers for persons with dementia and how it impacts their mental health. In this study, we aimed to examine caregivers' mental health indicators and their correlation structure based on the timing of hospice transition.
