"Responses to questions, phrased to elicit identical answers from the same individuals over time, are compared. The questions were used in a South African longitudinal study on the family-building process. Although consistency for certain questions was high, consistency was particularly low for questions on family-planning methods used and desired number of children at the time of marriage.... The need to evaluate the quality of data obtained in survey research, especially where heavy reliance is placed on memory recall, is stressed." (summary in AFR)

The lack of an in-vivo pathology marker for synuclein pathology has been a long standing challenge for dementia for Lewy bodies (DLB) research. This issue is critically important for phase II trials, which are often small, requiring the precise measurement of the biological effects, whether disease modifying or symptomatic. Recent advances have enabled the determination of alpha-synuclein pathology status with CSF measurements, using aggregation assays [RT-QUIC].

Background: Although novel treatments for Alzheimer's disease (AD) have begun to show modest therapeutic effects, agents that target hallmark AD pathology and offer neuroprotection are desired. Erythropoietin (EPO) is a glycoprotein hormone with neuroprotective effects but is faced with challenges including limited brain uptake and increased hematopoietic side effects with long-term dosing. Therefore, EPO has been modified and bound to a chimeric transferrin receptor monoclonal antibody (cTfRMAb); the latter shuttles EPO past the blood-brain barrier (BBB) into brain parenchyma and reduces its plasma exposure and potential for side effects.

Background: Novel anti-amyloid therapies (AAT) for Alzheimer's Disease (AD) have recently been approved in the United States, Japan and China, and are under regulatory review in Europe. Questions remain regarding the long-term effectiveness and value of these drugs when used in routine clinical practice. Data from follow-up studies will be important to inform their optimal use, including criteria for treatment initiation, monitoring strategies, stopping rules, pricing and reimbursement considerations.

Washington University School of Medicine, St. Louis, MO, USA.
Background: The well-accepted statistical efficacy inference approach for Alzheimer's disease (AD) clinical trials compares the absolute difference in change from baseline at the last study visit using MMRM (henceforth referred to as MMRM-Last-Visit). Recent AD clinical trials have shown that treatment effects may be manifested prior to 18 months. The objective is to evaluate models estimating an overall treatment effect across all post-baseline visits that may characterize disease modifying effects in contemporary early AD clinical trials.

Dementia patients often received one clinical diagnosis, yet most of these cases present multiple underlying pathologies. Bringing the transition from clinical-based to biological-based diagnosis holds promise with the diagnostic criteria proposed by the Alzheimer's Association (AA) Revised Criteria for Diagnosis and Staging of Alzheimer's Disease and the Neuronal Synuclein Disease Integrated Staging System (NSD-ISS). This session aims to explore the practical implications of the AA revised criteria for diagnosing and designing clinical trials in Lewy body disease (LBD).
