No results posted yet for this study

Summary

The negative symptoms and cognitive deficits are common in patients with schizophrenia, and do not respond well to antipsychotics. The effective treatments for negative symptoms and cognitive impairment are still to be explored. rTMS is a safe and non-invasive physical treatment, some studies has been indicated that the high frequency rTMS could increase the excitability of cortex, and has potentials to improve negative symptoms and cognitive function in schizophrenia. In this study, we explore the effects of iTBS on negative symptoms and cognitive function based on identifying the brain network connection of schizophrenia symptoms.

Conditions

Interventions

DEVICE

Intermittent theta burst stimulation

Intermittent theta burst stimulation(iTBS) on the left DLPFC, the left DLPFC will be targeted utilizing the localite neuronavigation system. The stimulation intensity is set at 80% of resting motor threshold(RMT), and the other parameters are set to triplet 50Hz bursts, repeat at 5Hz, 2s seconds on and 8 seconds off, 600 pulses per session, total duration of 3 minutes and 20 seconds.

DEVICE

Sham stimulation

The same procedure will be performed in sham group including the RMT assessment and the neuronavigation system for target localization, but the sham coil will vertical to the brain surface and deliver a very slight magnetic field, which have the same appearance and sound, and provide the same tactile sensations as the active coils.
