COLLABORATION OF A PEDIATRICIAN, SPEECH THERAPIST, AND DEFECTOLOGIST IN THE EARLY DIAGNOSIS OF SPEECH AND PSYCHOMOTOR DEVELOPMENT DELAYS IN CHILDREN

Abstract. The early identification and management of speech and psychomotor developmental delays in early childhood are critical for preventing long-term cognitive and social impairments. However, the traditional sequential diagnostic pathway often leads to significant delays in intervention. This research aims to comprehensively evaluate the clinical efficacy of a synchronous multidisciplinary team approach, specifically integrating the expertise of pediatricians, speech therapists, and defectologists in the primary diagnostic phase. Employing a prospective comparative methodology, the study monitored a cohort of preschool-aged children presenting with suspected developmental delays. The integrated literature review highlights the paradigm shift from isolated medical screening to holistic bio-psycho-pedagogical assessments, emphasizing the intense neuroplasticity of the first thousand days of life. Empirical results demonstrate that the synchronous collaborative model drastically reduces the latency period between initial suspicion and definitive diagnosis. Furthermore, the multidisciplinary approach significantly increases diagnostic accuracy, effectively differentiating between isolated speech delays, global developmental delays, and emerging autism spectrum disorders, which are frequently misclassified in isolated pediatric settings. The discussion emphasizes the unique and complementary roles of each specialist, wherein the pediatrician excludes somatic and neurological etiologies, the speech therapist assesses linguistic and phonetic constructs, and the defectologist evaluates broader cognitive and adaptive milestones. Ultimately, the study concludes that restructuring primary pediatric care to facilitate immediate interdisciplinary collaboration is an essential healthcare reform required to leverage critical windows of neurodevelopment, thereby fundamentally improving the lifelong trajectory of children with psychomotor and speech delays.摘要. 幼儿期言语与精神运动发育迟缓的早期识别与干预，对预防远期认知及社会功能损害具有关键意义。然而，传统顺序式诊断路径往往导致干预时机显著延后。本研究旨在全面评估同步多学科团队诊疗模式的临床效能，该模式在初始诊断阶段整合了儿科医师、言语治疗师及发育缺陷诊疗师（defectologist）的专业技术专长。研究采用前瞻性对照研究方法，对一组疑似发育迟缓的学龄前儿童队列开展追踪监测。综合文献综述揭示了从孤立性医学筛查向整体生物-心理-教育评估的范式转型，强调了生命最初1000天的高度神经可塑性。实证结果表明，同步协作诊疗模式可大幅缩短从初步疑似到明确诊断的时间间隔。此外，多学科诊疗路径显著提升了诊断准确率，能够有效区分孤立性言语发育迟缓、全面性发育迟缓及易在孤立儿科诊疗场景中被误分类的孤独症谱系障碍（autism spectrum disorders）。讨论环节阐述了各专科医师的独特互补作用：儿科医师排查躯体与神经源性病因，言语治疗师评估语言与语音结构发育情况，发育缺陷诊疗师则对更广泛的认知及适应能力里程碑进行评估。本研究最终得出结论：重构基层儿科医疗服务体系以实现即时跨学科协作，是充分利用神经发育关键窗口的必要医疗改革举措，可从根本上改善精神运动与言语发育迟缓儿童的终身发展轨迹。
