Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
SHAM_COMPARATOR: rTMS targeting the right DLPFC
60 patients will be randomly allocated into this group,half of them will receive iTBS on the right DLPFC,while the other half will receive sham stimulation.
|
high frequency(20Hz) repetitive transcranial magnetic stimulation on dorsolateral prefrontal cortex(DLPFC) .Duration:10 days.
|
SHAM_COMPARATOR: rTMS targeting the left LPC
60 patients will be randomly allocated into this group,half of them will receive iTBS on left LPC,while the other half will receive sham stimulation.
|
high frequency(20Hz) repetitive transcranial magnetic stimulation on left parietal cortex(LPC).Duration:10 days
|
NO_INTERVENTION: Observation group
To investigate the abnormalities of hippocampal neurogenesis in patients with early schizophrenia(n=30) compared to healthy controls(n=30)
