- any medical condition which requires treatment with a medication with psychotropic effects.
- significant risk of suicidal or homicidal behavior;
- cognitive or language limitations, or any other factor that would preclude subjects providing informed consent.
- medical contraindications to treatment with risperidone (e.g. neuroleptic malignant syndrome with prior risperidone exposure).
- lack of response to a prior adequate trial of risperidone.
- requires treatment with an antidepressant or mood stabilizing medication.
- presence of an electrically, magnetically or mechanically activated implant (including cardiac pacemaker), an intracerebral vascular clip, or any other electrically sensitive support system.

Active Comparator
Sham Comparator
Active comparator: tDCS & Risperidone
Sham comparator: tDCS & Risperidone
In the active arm, active tDCS will be applied using a Soterix Medical 1x1 line tDCS Model 1300 low-intensity stimulator at a current of 2 milliampere (mA) for 20 minutes, twice a day for five consecutive days, for a total of 10 sessions.
In the sham arm, active tDCS will be applied using a Soterix Medical 1x1 line tDCS Model 1300 low-intensity stimulator at a current of 2mA for 1 minute, twice a day for five consecutive days, for a total of 10 sessions.
