About this study

This study is an before-after study in the same patient, which enrolled 36 psychiatric patients with refractory auditory hallucinations. The target of patient intervention relies on the results of magnetoencephalography localization. The medication and dosage remain unchanged during the intervention period. The investigators assume that the intervention targets for each auditory hallucination patient are individualized.

Read the detailed description

This study is divided into two parts:

  1. Target determination. Firstly, MEG data of the patient's resting and task states are collected, and a precise localization model using magnetoencephalography is applied to locate the precise location of the patient's abnormal signals in the brain, which is then used as the intervention target. Based on the patient's tolerance for single day intervention, the appropriate number of targets is generally 2-4. The upper limit of targets is 4.
  2. RTMS individualized intervention. Application of rTMS for 1Hz low-frequency intervention, with intervention parameters of 1400 sessions, 100% exercise threshold, and a total of 23 minutes per session. After each target intervention, rest for half an hour to one hour. The pseudo stimulation intervention lasted for 10 days in the first and second weeks, and the scale was evaluated after the end of the pseudo stimulation. After resting for 2 weeks, enter the 3-4 weeks of real stimulation, with 5 days of intervention per week for a total of 10 days. 2-4 targets per day, 23 minutes per target, with 30-60 minutes between interventions for each target. After the fourth week, evaluate the scale. Follow up evaluations will be conducted on the 7th, 14th, 30th, 60th, and 90th day after intervention. By analyzing and evaluating data, explore individualized treatment plans for auditory hallucinations in clinical practice.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Reduction rate of the AHRS scale

    AHRS (Auditory Hallucinations Rating Scale) is a scale used to assess patients' auditory hallucinations within the past 24 hours. The minimum score of the AHRS scale is 0, indicating the absence of auditory hallucination symptoms, while the maximum score represents the most severe level of symptoms. The specific numerical values need to refer to the version of the scale being used.

    Measured: From enrolment to the end of the 2-week pseudostimulation treatment. From 2 weeks rest after the end of pseudostimulation treatment to the end of 2 weeks of true stimulation treatment.

Secondary outcomes (2)
  1. Reduction rate of the PSYRATS scale

    PSYRATS(Psychotic Symptom Rating Scales) is a scale used to assess patients' auditory hallucinations within the past week. The PSYRATS scale is a semi-structured interview scale designed for assessing the multidimensional symptoms of auditory hallucinations and delusions, consisting of 17 items. The scale is scored on a 0-4 rating scale, with detailed explanations for each rating level, and is administered by trained staff to evaluate patients. Theoretically, the minimum score of the PSYRATS scale is 0 (when all items are scored 0), while the maximum score is 68 (when all items are scored 4). A higher score indicates more severe symptoms.

    Measured: From enrolment to the end of the 2-week pseudostimulation treatment. From 2 weeks rest after the end of pseudostimulation treatment to the end of 2 weeks of true stimulation treatment.

  2. Reduction rate of the PNASS scale

    PNASS (Positive and Negative Syndrome Scale) is a scale for evaluating Psychiatric disorders. Each item is scored on a scale from 1 to 7, with 1 being the lowest score and 7 being the highest. Therefore, the minimum possible score on the PANSS is 30, and the maximum is 210. A higher score indicates more severe symptoms.

    Measured: From enrolment to the end of the 2-week pseudostimulation treatment. From 2 weeks rest after the end of pseudostimulation treatment to the end of 2 weeks of true stimulation treatment.
