Summary

In this study, investigators designed a double-blind randomized trial to prove a more reliable evidence to show how the treatment by using high-definition transcranial direct current stimulation (HD-tDCS) can relieve negative symptoms in patients with predominant negative symptoms of schizophrenia, especially on improving participants' anhedonia condition and social cognition, through stimulating the left dorsolateral prefrontal cortex (DLPFC). Participants will be divided into active and sham HD-tDCS groups equally.

DEVICE

HD-tDCS

HD-tDCS is going to be delivered at 1.5 mA intensity for 20 minutes once a day (+15 s fade-in and fade-out); sessions will be performed on 10 days 5 consecutive weekdays with sustained effects at T1 and T2. HD-tDCS will be used with the anode placed over the left DLPFC (F3) surrounded by four cathodes at F5, F1, FC3, and AF3 based on the 10/20 international EEG system.

DEVICE

Sham HD-tDCS

HD-tDCS is going to be used with the anode placed over the left DLPFC (F3) surrounded by four cathodes at F5, F1, FC3, and AF3 based on the 10/20 international EEG system; sessions will be performed on 10 days 5 consecutive weekdays with sustained effects at T1 and T2. This group will have a 20-min-sham stimulation.
