Abstract: Cognitive dysfunction disorders have emerged as a major public health challenge in aging societies, early precise diagnosis and management are even more challenging. Using the ATN biomarker diagnostic framework for Alzheimer's disease(AD) as a paradigm, promoting biomarker-based precision diagnosis has become an important concept in the field of cognitive dysfunction disorders diagnosis and treatment. However, the diagnostic efficacy of the ATN framework has certain limitations.Therefore, the new diagnostic pathway advocates the starting from the clinical cognitive dysfunction characteristics of patients to form preliminary diagnostic hypotheses, which then serve as the entry point for selecting biomarkers. To improve the assessment system, develop reasonable accessory examination pathways, and prioritize biomarkers with the highest informational value, the "Expert consensus on the selection of accessory examinations for cognitive dysfunction disorders based on the biomarker diagnostic framework" has been compiled. This consensus integrates a systematic summary of current domestic and international evidence, aiming to assist clinicians in the rational and effective use of diagnostic biomarkers.By promoting standardized diagnostic and management practices, this consensus seeks to enhance the efficiency of clinical decision-making, enabling accurate diagnosis and differential diagnosis of cognitive dysfunction disorders with minimal yet informative testing.

摘要: 认知功能障碍疾病是老龄化社会面临的重大公共卫生挑战,早期精准诊断与管理尤为困难。以阿尔茨海默病ATN生物学标志物诊断框架(以下简称ATN诊断框架)为范式,推动基于生物学标志物的精准诊断成为该领域的核心理念。但ATN诊断框架的诊断效能有限,故新的诊断路径倡导以临床认知功能障碍特征为起点,形成初步诊断假设,以此作为选择生物学标志物的切入点。为完善评估体系、制定合理的辅助检查路径,并优先选择信息量最高的生物学标志物,撰写《基于生物学标志物诊断框架的认知功能障碍疾病辅助检查选择专家共识》。系统总结国内外证据,旨在指导临床医师合理、有效地应用诊断性生物学标志物,推动认知功能障碍疾病诊断管理的同质化,力求以最少的检查获取最多的诊断信息,最终促使我国医务人员在临床实践中有效实现认知功能障碍疾病的诊断与鉴别诊断。
