    Apathy as a Treatment Target in Alzheimer's Disease: Implications for Clinical Trials
    (Elsevier, 2022-02) Mortby, Moyra E.; Adler , Lawrence; Agüera-Ortiz , Luis; Bateman, Daniel R.; Brodaty , Henry; Cantillon , Marc; Geda , Yonas E.; Ismail, Zahinoor; Lanctôt, Krista L.; Marshall, Gad A.; Padala, Prasad R.; Politis, Antonios; Rosenberg, Paul B.; Siarkos, Kostas; Sultzer, David L.; Theleritis, Christos; ISTAART NPS PIA; Psychiatry, School of Medicine
    Apathy is one of the most prevalent, stable and persistent neuropsychiatric symptom across the neurocognitive disorders spectrum. Recent advances in understanding of phenomenology, neurobiology and intervention trials highlight apathy as an important target for clinical intervention. We conducted a comprehensive review and critical evaluation of recent advances to determine the evidence-based suggestions for future trial designs. This review focused on 4 key areas: 1) pre-dementia states; 2) assessment; 3) mechanisms/biomarkers and 4) treatment/intervention efficacy. Considerable progress has been made in understanding apathy as a treatment target and appreciating pharmacological and non-pharmacological apathy treatment interventions. Areas requiring greater investigation include: diagnostic procedures, symptom measurement, understanding the biological mechanisms/biomarkers of apathy, and a well-formed approach to the development of treatment strategies. A better understanding of the subdomains and biological mechanisms of apathy will advance apathy as a treatment target for clinical trials.

    (Wiley, 2021) Miller, David S.; Robert, Philippe; Ereshefsky, Larry; Adler, Lawrence; Bateman, Daniel; Cummings, Jeff; DeKosky, Steven T.; Fischer, Corinne E.; Husain, Masud; Ismail, Zahinoor; Jaeger, Judith; Lerner, Alan J.; Li, Abby; Lyketsos, Constantine G.; Manera, Valeria; Mintzer, Jacobo; Moebius, Hans J.; Mortby, Moyra; Meulien, Didier; Pollentier, Stephane; Porsteinsson, Anton; Rasmussen, Jill; Rosenberg, Paul B.; Ruthirakuhan, Myuri T.; Sano, Mary; Zucchero Sarracini, Carla; Lanctôt, Krista L.; Psychiatry, School of Medicine
    Introduction: Apathy is common in neurocognitive disorders (NCD) but NCD-specific diagnostic criteria are needed. Methods: The International Society for CNS Clinical Trials Methodology Apathy Work Group convened an expert group and sought input from academia, health-care, industry, and regulatory bodies. A modified Delphi methodology was followed, and included an extensive literature review, two surveys, and two meetings at international conferences, culminating in a consensus meeting in 2019. Results: The final criteria reached consensus with more than 80% agreement on all parts and included: limited to people with NCD; symptoms persistent or frequently recurrent over at least 4 weeks, a change from the patient's usual behavior, and including one of the following: diminished initiative, diminished interest, or diminished emotional expression/responsiveness; causing significant functional impairment and not exclusively explained by other etiologies. Discussion: These criteria provide a framework for defining apathy as a unique clinical construct in NCD for diagnosis and further research.
