研究目的:

1.主要目的:本项目拟以紊乱症状显著的TRS患者为研究对象,明确TIS前后E/I平衡,γ振荡及网络功能的影响;阐明TIS靶向调控DMN改善TRS紊乱症状的神经机制。 2.次要目的: ①研究TIS靶向调控DMN治疗TRS紊乱症状的临床疗效与安全性; ②阐明TIS的治疗效应及其特异性,为TRS的个体化精准治疗提供科学依据; ③推动TIS的临床转化。  

Objectives of Study:

1. Primary Objective: This project aims to investigate patients with TRS exhibiting prominent disorganized symptoms, to determine the effects of TIS on E/I balance, gamma oscillations, and network function, and to elucidate the neural mechanisms by which TIS targeting the DMN improves disorganized symptoms in TRS. 2. Secondary Objectives: (1)To investigate the clinical efficacy and safety of TIS targeting the DMN for the treatment of disorganized symptoms in TRS; (2)To elucidate the therapeutic effects and specificity of TIS, providing a scientific basis for personalized precision treatment of TRS; (3)To promote the clinical translation of TIS.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.符合DSM-5精神分裂症诊断标准; 2.年龄18-55岁,右利手,受教育水平初中或以上(>=9年); 3.根据主治医生的判断,结合既往病史、就诊记录详细追踪患者抗精神病药物治疗情况,满足美国精神病治疗应答和抵抗工作组(TRRIP)制定治疗抵抗的标准:接受>=2种 不同的非氯氮平抗精神病药、足量(>=600 mg/天氯丙嗪等效剂量)、足疗程(>=6周持续治疗剂量)且依从性良好(>= 80%服药)治疗后,临床总体印象-疾病严重程度量表(CGI-S)评分>=4分(功能损害为中度以上)、阳性与阴性症状量表(PANSS)阳性症状条目中2项或以上>=4分(精神症状严重度为中度以上)、症状未缓解; 4.伴中等及以上程度的紊乱症状,PANSS量表紊乱症状评分>=21分; 5.主治医生与患者及家属共同决策在原有的药物治疗基础上接受TIS治疗,允许正在使用氯氮平的患者入组,但需稳定剂量(>=4周)且无严重副作用。

Inclusion criteria

1. Meets the DSM-5 diagnostic criteria for schizophrenia; 2. Aged 18-55, right-handed, with an education level of junior high school or higher (>=9 years); 3. According to the attending physician's judgment, and based on past medical history and detailed follow-up of the patient's antipsychotic treatment records, meets the treatment-resistant criteria established by the American Psychiatric Association Treatment Response and Resistance in Psychosis (TRRIP) working group: after receiving >=2 different non-clozapine antipsychotic drugs at adequate doses (>=600 mg/day chlorpromazine equivalent), for an adequate duration (>=6 weeks at continuous therapeutic doses), and with good adherence (>=80% medication intake), the Clinical Global Impression - Severity scale (CGI-S) score is >=4 (indicating moderate or greater functional impairment), and >=2 items on the positive subscale of the Positive and Negative Syndrome Scale (PANSS) score >=4 (indicating moderate or greater severity of symptoms), with no symptom remission; 4. Exhibits moderate or greater disorganized symptoms, with a PANSS disorganized symptom score >=21; 5. The attending physician, together with the patient and family, decide to receive TIS treatment on the basis of existing medication. Patients currently using clozapine are allowed to enroll, provided the dose is stable (>=4 weeks) and there are no serious side effects.

排除标准:

1.存在任何磁共振扫描禁忌症; 2.存在ECT治疗史(ECT通过脑部电流诱发癫痫,对脑功能和结构有显著且可能持久的影响); 3.过去6个月内接受过任何神经调控治疗(包括rTMS、tDCS、tACS); 4.共病其他类的精神疾病(如精神发育迟滞、强迫症、人格障碍等); 5.共病存在酒精或药物滥用或精神活性物质依赖史; 6.合并有脑器质性疾病或其他不稳定或严重躯体疾病者; 7.准备怀孕、正在怀孕或哺乳的患者; 8.极度兴奋激越、木僵、消极自杀等不合作或存在显著风险的患者。

Exclusion criteria:

1. Presence of any contraindications for MRI scans; 2. History of ECT treatment (ECT induces seizures through electrical currents in the brain, which can have significant and potentially lasting effects on brain function and structure); 3. Received any neurostimulation treatments in the past 6 months (including rTMS, tDCS, tACS); 4. Comorbid other types of mental disorders (such as intellectual disability, obsessive-compulsive disorder, personality disorders, etc.); 5. Comorbid history of alcohol or drug abuse or dependence on psychoactive substances; 6. Presence of organic brain diseases or other unstable or severe physical illnesses; 7.
