研究目的:

(1)本研究首次将经颅交流电刺激治疗(tACS)应用于持续性姿势-感知性头晕(PPPD)患者,试图为PPPD的非药物治疗开拓新的方法。 (2)进一步探讨经颅交流电刺激治疗对PPPD患者作用的可能的机制:采用先进的静息态功能磁共振(rs-fMRI)技术,构建PPPD患者的全脑功能网络,计算网络相关参数,对PPPD的病理生理机制进一步探索,分析PPPD患者在经颅交流电刺激治疗前后脑网络功能连接的变化,试图研究经颅交流电刺激作用于PPPD的可能的机制:①改变PPPD患者楔叶和楔前叶的自发活动及其与其他区域的功能连接,改善视觉和前庭信息的异常整合改变,减轻视觉及姿势诱发的头晕及不稳;②改变前庭和焦虑相关脑区的活动,改善焦虑状态,进而改善头晕症状。  

Objectives of Study:

(1) This study is the first to apply transcranial alternating current stimulation therapy to patients with persistent postural perception dizziness (PPPD), trying to open up a new method for non-drug treatment of PPPD. (2) To further explore the possible mechanism of the effect of transcranial alternating current stimulation on PPPD patients: advanced resting-state functional magnetic resonance imaging (rs-fMRI) technology was used to construct the whole brain functional network of PPPD patients, calculate the network related parameters, and further explore the pathophysiological mechanism of PPPD. To analyze the changes of brain network functional connectivity in patients with PPPD before and after transcranial alternating current stimulation, and to study the possible mechanism of transcranial alternating current stimulation in PPPD: (1) to change the spontaneous activity of cuneus and precuneus and their functional connectivity with other areas in patients with PPPD, and to improve the abnormal integration of visual and vestibular information. Reduce the dizziness and instability induced by vision and posture; (2). Change the activity of vestibular and anxiety-related brain areas, improve anxiety state, and then improve dizziness symptoms.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1)PPPD临床诊断必须满足所有5项诊断标准(参照2017年Barany学会诊断标准): ①在多数时间中存在头晕、不稳、非旋转性眩晕中的一个或多个症状,持续时间≥3 个月。 A.症状持续时间长,常持续数小时,但症状严重程度可起伏; B.症状不需要一整天持续存在。 ②持续性前庭症状的产生无明确的诱因,但以下 3 种因素可导致症状加重。 A.直立姿势; B.主动或被动运动,但与运动方向或位置无关; C.暴露于移动视觉刺激或复杂视觉环境。 ③通常由引起头晕/眩晕、平衡障碍的疾病所触发,包括急性/发作性/慢性 前庭综合征,其他神经科、内科疾病以及精神心理疾病。 A.当触发事件为急性/发作性疾病时,触发事件缓解后,患者的临床症状 表现为诊断标准①所示的模式。最初患者的症状可呈间歇性发作,此后逐渐演变 为持续存在。 B.当触发事件为慢性综合征时,患者的临床症状呈现缓慢起病、渐进性加 重的特点。 ④症状给患者带来严重的痛苦或功能障碍。 ⑤症状不能由其他疾病更好地解释。 2)年龄18-80岁; 3)患者同意参与并签署知情同意书; 4)可以配合定期进行随访和完成研究;

Inclusion criteria

1: The clinical diagnosis of PPPD must meet all five diagnostic criteria: (1). One or more symptoms of dizziness, instability and non-rotational vertigo existed in most of the time, and the duration was >= 3 months; 1). Symptoms last for A long time, often lasting for several hours, but the severity of symptoms can fluctuate; 2). Symptoms do not need to persist throughout the day. (2). There was no clear inducement for the occurrence of persistent vestibular symptoms, but the following three factors could aggravate the symptoms. 1). Upright posture; 2). Active or passive motion, but independent of direction or position of motion; 3). Exposure to moving visual stimuli or complex visual environments; (3). It is usually triggered by diseases causing dizziness/vertigo and balance disorders, including acute/paroxysmal/chronic vestibular syndrome, other neurological and medical diseases and mental and psychological diseases. 1). When the triggering event is acute/episodic disease, the patient's clinical signs and symptoms after the triggering event has resolved shows the pattern shown in the diagnostic criteria; 2). At first, the patient's symptoms may be intermittent, and then gradually evolve into persistent. B. When the trigger event is a chronic syndrome, the patient's clinical signs and symptoms is characterized by a slow onset and progressive exacerbation. (4) Symptoms bring severe pain or dysfunction to patients;(5). Symptoms could not be better explained by other diseases. 2: 18-80 years old; 3: The patient agrees to participate and signs the informed consent; 4: Can cooperate with regular follow-up and complete the study.
