在北京市自然科学基金的支持下，韩云毅与中国科学院自动化所科研人员合作，深入揭示了一种新 型磁刺激——个体化加速间歇性θ波刺激改善阴性症状的神经机制，同时开展了随机对照双盲的临床研 究。研究共纳入80名以阴性症状为主的精神分裂症患者，研究人员将其随机分为真刺激组和伪刺激组。 真刺激组接受为期10天的个体化加速间歇性θ波刺激治疗，每天刺激4次，每次1800个脉冲。伪刺激组与 真刺激组做相同的治疗流程，但刺激器不产生任何磁刺激。 对比结果显示，真刺激组在治疗后的第4周，阴性症状显著减轻，其效果明显优于伪刺激组。两组 的响应率（即阴性症状缓解50%以上的人群）分别为77.5%和17.5%。真刺激组的阴性症状评分比伪刺激 组平均值降低了4.10分，效应量达到0.83，属于中等至高度的治疗效果，且疗效在3个月的随访期间仍然 显著。此外，研究还发现，真刺激组患者在接受治疗后，左侧颞中回神经活动降幅显著，且中脑与颞中 回之间的功能连接也相对减弱。这些神经活动的变化与阴性症状的改善密切相关。 从实验结果来看，该治疗方案有效改善了精神分裂症阴性症状，为精神分裂症患者提供了新的治疗 选择。 下一步，韩云毅还将计划开展更大样本量的多 ...

Core Insights - The theme for World Mental Health Day 2025 is "Everyone enjoys mental health services," highlighting the increasing challenges in China's mental health sector [1] - The World Health Organization (WHO) reports approximately 24 million schizophrenia patients globally, with over 8 million in China, indicating a significant public health issue [1] - Schizophrenia is increasingly recognized as a chronic brain disease rather than a functional disorder, necessitating long-term treatment strategies [1][2] Treatment Challenges - Approximately 80% of schizophrenia patients experience onset between the ages of 16 and 35, a critical period for social integration [2] - Poor medication adherence is a major challenge in treating schizophrenia, with a treatment interruption rate of 75% in China, leading to high relapse rates of 77% within one year and 90% within two years [3] - Each relapse can increase direct medical costs by four times, emphasizing the need for improved adherence strategies [3] Long-Acting Injectable Medications - The recently updated "Chinese Schizophrenia Prevention and Treatment Guidelines (2025 Edition)" emphasizes the clinical value of long-acting injectable antipsychotics, recommending their early use while respecting patient preferences [4] - Long-acting injectables can significantly reduce medication frequency and improve adherence compared to oral medications [4] - Current clinical usage of long-acting injectables in China is less than 5%, compared to 25%-30% in Europe and the U.S., indicating a substantial gap [5] Government and Healthcare Initiatives - Efforts are underway to increase the clinical use of long-acting injectables in China, including enhanced education for healthcare providers and patients, as well as the inclusion of these medications in health insurance coverage [5] - Government subsidy programs in cities like Shanghai are providing free medication support to patients, aiming to improve treatment access and adherence [5]
