Exploring the Feasibility of Transcranial Ultrasound Stimulation in the Treatment of Schizophrenia
Source: ClinicalTrials.gov · Last updated 2 Jun 2026
Brief summary (registry, in English)
1. The purpose of this study is to evaluate the safety and feasibility of transcranial ultrasound stimulation (TUS) treatment in patients with schizophrenia. Subjects are individuals diagnosed with schizophrenia who will receive non-invasive, low-intensity pulsed ultrasound stimulation targeting the hippocampus and its surrounding regions. Evaluations will be conducted before and after the treatment sessions, including electrocardiograms (ECG), blood biochemistry tests, psychiatric symptom assessments, depression level assessments, and cognitive function assessments. 2. The primary objective is to assess the safety of this intervention in patients with schizophrenia. The secondary objective is to explore whether the current stimulation parameters may lead to improvements in the assessed symptoms. Ultimately, this study aims to support the future application of low-intensity pulsed ultrasound as a potential intervention to alleviate symptoms of schizophrenia and improve patients' quality of daily life.

- Presence of a family history of epilepsy
- Any significant medical conditions that could affect normal brain function (including but not limited to stroke, CNS infections or tumors, or other major neurological diseases).
- Presence of a cardiac pacemaker, implanted medication pump, intracardiac lines, or acute/unstable cardiac disease, as well as intracranial implants (e.g., aneurysm clips, shunts, stimulators, cochlear implants, or electrodes) or any other metallic objects in or near the head (excluding oral metal objects)
- Current use of medications known to lower the seizure threshold or increase the risk of suicidal behavior
- Presence of severe and uncontrolled systemic diseases (e.g., heart failure, liver failure, renal failure, vitamin B12 deficiency, hypothyroidism), as determined by the investigator to be unsuitable for study participation
- Patients with uncontrolled diabetic retinopathy accompanied by active fundus hemorrhage
- Presence of contraindications to the medical devices used in this study (including pulsed ultrasound, EEG, and CT), such as unheindividuals with obvious head trauma, unhealed head surgery, or significant physical or psychiatric symptoms.
