Development and assessment of a brief screening tool for psychosis in dementia.

INTRODUCTION: Hallucinations and delusions (H+D) are common in dementia, but screening for these symptoms-especially in busy clinical practices-is challenging. METHODS: Six subject matter experts developed the DRP3™ screen, a novel valid tool to detect H+D in dementia, assessed its content validity through alignment with DRP reference assessments (Scale for the Assessment of Positive Symptoms-Hallucinations + Delusions, Neuropsychiatric Inventory-Questionnaire, International Psychogeriatric Association Criteria), and retrospectively investigated its ability to detect H+D in HARMONY trial (NCT03325556) enrollees. RESULTS: All items from three reference assessments demonstrated significant agreement with the DRP3 screen among raters (P < .0001). Retrospectively applying the DRP3 screen to HARMONY identified all (N = 392) trial enrollees. DISCUSSION: The DRP3 screen, comprising three yes/no questions, is a content-valid tool for detecting H+D in dementia that aligned with current reference assessments and successfully identified trial participants when retrospectively applied to a completed trial. Within busy practice constraints, the DRP3 screen provides a brief tool for sensitive detection of H+D in patients with dementia.

Current and Emerging Solutions to Challenges in the Management of Alzheimer's Disease.

​​​​Effective multifactorial management of Alzheimer's disease (AD) requires a triadic alliance of the clinician, the patient, and the patient's family and/or care partner(s). During the evaluation process and when the diagnosis of AD is delivered, these parties must work together to set goals and develop care plans. Care plans should be designed to help the patient maintain safety and autonomy as long as he or she can and, once autonomy is no longer possible, to allow the patient and care partner(s) to experience as much comfort and the best possible quality of life for as long as possible. In this Academic Highlights, faculty members from neurology, psychiatry, neuropsychology, and primary care share their recommendations, supported by current evidence and guidelines, for handling the complexities of providing care for patients with AD.

Tip of the Iceberg: Assessing the Global Socioeconomic Costs of Alzheimer's Disease and Related Dementias and Strategic Implications for Stakeholders.

While it is generally understood that Alzheimer's disease (AD) and related dementias (ADRD) is one of the costliest diseases to society, there is widespread concern that researchers and policymakers are not comprehensively capturing and describing the full scope and magnitude of the socioeconomic burden of ADRD. This review aimed to 1) catalogue the different types of AD-related socioeconomic costs described in the literature; 2) assess the challenges and gaps of existing approaches to measuring these costs; and 3) analyze and discuss the implications for stakeholders including policymakers, healthcare systems, associations, advocacy groups, clinicians, and researchers looking to improve the ability to generate reliable data that can guide evidence-based decision making. A centrally emergent theme from this review is that it is challenging to gauge the true value of policies, programs, or interventions in the ADRD arena given the long-term, progressive nature of the disease, its insidious socioeconomic impact beyond the patient and the formal healthcare system, and the complexities and current deficiencies (in measures and real-world data) in accurately calculating the full costs to society. There is therefore an urgent need for all stakeholders to establish a common understanding of the challenges in evaluating the full cost of ADRD and define approaches that allow us to measure these costs more accurately, with a view to prioritizing evidence-based solutions to mitigate this looming public health crisis.

Cognitive Assessment of Alzheimer's Disease and Dementias in Clinical Practice: Pragmatics of Brief Instruments and Neuropsychological Evaluation.

Detection of cognitive impairment and dementia (CID) through the use of brief cognitive assessment tools (BCATs) is the first step to establishing an accurate diagnosis and care plan for individuals seen in primary practices. While the cognitive-behavioral syndrome and underlying etiology may not be readily apparent through brief assessment, clinicians can refer patients for a more comprehensive neuropsychological evaluation. A timely diagnosis maximizes the potential for patients to be involved in decision-making and planning for their future, and allows for expedited intervention and harm reduction. This activity provides a practical review of validated and standardized BCATs that can aid in the detection of CID; reviews cognitive and neuropsychological domains and their clinical relevance; and delineates circumstances for referral to neuropsychology and the utility of neuropsychological evaluation to practicing clinicians.
