Brief Summary:
Based on the current background and our previous studies, TUS has been proved that rTUS intervention could induce long-term potentiation like (LTP-like) plasticity and neuromodulate the brain cortex in schizophrenia patients. rTUS over the left dorsolateral prefrontal cortex (DLPFC) can alleviate the negative symptoms in schizophrenia. In this double-blind, randomized, sham-controlled study, the efficacy of different treatment options and mechanisms of low-intensity rTUS on negative symptoms will be investigated.
Detailed Description:
Negative symptoms is a core symptom of schizophrenia related to poor functional outcome which remains largely treatment refractory. Prior studies indicated that abnormalities in the prefrontal-temporal circuit and glutamate/GABA imbalances may be the root causes of negative symptoms. Transcranial ultrasound stimulation (TUS), an emerging non-invasive neuromodulation technique, can modulate neuroplasticity in the prefrontal and temporal cortex. In this double-blind, randomized, sham-controlled study, the efficacy of different treatment options and mechanisms of low-intensity rTUS on negative symptoms will be investigated. Schizophrenia inpatients with predominant negative symptoms will be recruited and randomly allocated into single-target group (left DLPFC), both-target group (both left DLPFC and right STG) or sham group in ratio of 1:1:1. This study aims to determine the efficacy of TUS and to reveal its underlying neural mechanism. MEPs, TEPs ,multi-modal MRI and rs-EEG will be detected. Neuropsychological assessments will also be conducted to develop the optimized treatment strategy. The study points to a novel and promising therapeutic neuromodulation approach that may improve the functional outcome of schizophrenia, which has been the main cause of mental disability.
