Objective: To assess comprehension and application of the McDonald criteria. Background: Studies suggest that knowledge gaps for specific core elements of the McDonald criteria may contribute to multiple sclerosis (MS) misdiagnosis. Methods: Neurology residents (NR) and multiple sclerosis specialists (MSS) in North America completed a web-based survey. Results: A total of 160 participants were included: 72 NR and 88 MSS. Syndromes incorrectly identified as typical of MS included: complete transverse myelopathy (35% NR and 15% MSS), intractable vomiting/nausea/hiccoughs (20% NR and 5% MSS), and bilateral optic neuritis/unilateral optic neuritis with poor visual recovery (17% NR and 10% MSS). Periventricular magnetic resonance imaging (MRI) lesions were correctly identified by 39% NR and 52% MSS, and juxtacortical lesions were correctly identified by 28% NR and 53% MSS. The correct definition of “periventricular” was chosen by 38% NR and 61% MSS, and that of “juxtacortical” was chosen by 19% NR and 54% MSS. Regions incorrectly identified for MRI dissemination in space fulfillment included the optic nerve (31% NR and 26% MSS) and the subcortical white matter (11% NR and 18% MSS). The majority of participants assessed previous non-specific neurological symptoms without objective evidence of a central nervous system (CNS) lesion as sufficient for clinical dissemination in time. Conclusion: The McDonald criteria are often misunderstood and misapplied. Concerted educational efforts may prevent MS misdiagnosis.

多发性硬化症诊断的挑战:McDonald 标准的误解和误用

目的:评估麦当劳标准的理解和应用。背景:研究表明,McDonald 标准特定核心要素的知识差距可能导致多发性硬化症 (MS) 误诊。方法:北美的神经内科住院医师 (NR) 和多发性硬化症专家 (MSS) 完成了一项基于网络的调查。结果:总共包括 160 名参与者:72 名 NR 和 88 名 MSS。被错误识别为典型 MS 的综合征包括:完全横贯性脊髓病(35% NR 和 15% MSS)、顽固性呕吐/恶心/打嗝(20% NR 和 5% MSS)和双侧视神经炎/视力恢复不佳的单侧视神经炎(17% NR 和 10% MSS)。39% NR 和 52% MSS 正确识别脑室周围磁共振成像 (MRI) 病变,28% 的 NR 和 53% 的 MSS 正确识别了皮层旁病变。38% NR 和 61% MSS 选择了“脑室周围”的正确定义,19% NR 和 54% MSS 选择了“近皮质”的定义。空间实现中 MRI 传播被错误识别的区域包括视神经(31% NR 和 26% MSS)和皮层下白质(11% NR 和 18% MSS)。大多数参与者评估了先前的非特异性神经系统症状,而没有中枢神经系统 (CNS) 病变的客观证据,足以及时进行临床传播。结论:麦当劳标准经常被误解和误用。协调一致的教育工作可以防止 MS 误诊。19% NR 和 54% MSS 选择了“juxtacortical”。空间实现中 MRI 传播被错误识别的区域包括视神经(31% NR 和 26% MSS)和皮层下白质(11% NR 和 18% MSS)。大多数参与者评估了先前的非特异性神经系统症状,而没有中枢神经系统 (CNS) 病变的客观证据,足以及时进行临床传播。结论:麦当劳标准经常被误解和误用。协调一致的教育工作可以防止 MS 误诊。19% NR 和 54% MSS 选择了“juxtacortical”。空间实现中 MRI 传播被错误识别的区域包括视神经(31% NR 和 26% MSS)和皮层下白质(11% NR 和 18% MSS)。大多数参与者评估了先前的非特异性神经系统症状,而没有中枢神经系统 (CNS) 病变的客观证据,足以及时进行临床传播。结论:麦当劳标准经常被误解和误用。协调一致的教育工作可以防止 MS 误诊。大多数参与者评估了先前的非特异性神经系统症状,而没有中枢神经系统 (CNS) 病变的客观证据,足以及时进行临床传播。结论:麦当劳标准经常被误解和误用。协调一致的教育工作可以防止 MS 误诊。大多数参与者评估了先前的非特异性神经系统症状,而没有中枢神经系统 (CNS) 病变的客观证据,足以及时进行临床传播。结论:麦当劳标准经常被误解和误用。协调一致的教育工作可以防止 MS 误诊。
