Brief Summary

The purpose of the present research is to test a potential new treatment for auditory verbal hallucinations in schizophrenia that uses transcranial Direct Current Stimulation (tDCS), a neurostimulation technique that passes an extremely weak electric current through the brain. During the treatment, two electrodes are positioned on the scalp above regions of the brain implicated in abnormal cortical activity associated with auditory verbal hallucinations in schizophrenia. Due to the directional flow of current, one electrode, termed "cathodal",inhibits cortical activity, and the other, termed "anodal", increases cortical activity. These electrodes will be placed such that cathodal stimulation is applied to an area associated with hyperactivity and anodal stimulation to an area associated with hypoactivity. One preliminary study has revealed that this form of neurostimulation can alleviate auditory verbal hallucination symptoms both immediately following five days of treatment and up to three months after the final treatment. The goal of this study is to replicate these effects and explore the mechanisms that may underpin them.

Outcome Measures

Primary Outcomes (1)

  • Severity of Refractory Auditory Hallucinations

    Total score: Auditory hallucinations as determined by Auditory Hallucinations Rating Scale (AHRS). This is a seven item scale rating auditory hallucinations. Total score ranges from 1 to 41, with higher scores more severe.

    Auditory Hallucination Rating Scale score after one month

Eligibility Criteria

Age18 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Structured Clinical Interview for DSM Disorders (SCID) primary diagnosis of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders-Version IV) schizophrenia or schizoaffective disorder
  • Persistent auditory verbal hallucinations
  • Right handed
  • Stable antipsychotic medication for \> 4 weeks
  • Normal hearing
  • If female and not infertile, must agree to use one of the following forms of contraception for the duration of study participation: systemic hormonal treatment, an interuterine device (IUD) which was implanted at least 2 months prior to screening, or "double-barrier" contraception
  • Willing/capacity to provide informed consent

You may not qualify if:

  • Substance dependence or abuse (excluding nicotine) in the past 90 days
  • Current significant laboratory abnormality
  • History of seizure, epilepsy in self or fist degree relatives, stroke, brain surgery, head injury with loss of consciousness \> 1 hour or clear cognitive sequelae, intracranial metal implants, known structural brain lesion, devices that may be affected by transcranial Direct Current Stimulation (tDCS) (pacemaker, medication pump, cochlear implant, implanted brain stimulator)
  • Frequent and persistent migraines
  • History of adverse reaction to neurostimulation or open skin wounds that would preclude safe placement of tDCS electrodes
  • Participation in study of investigational medication/device within 4 weeks
  • Current use of medications known to lower seizure threshold (lithium, serotonergic or tricyclic antidepressants)
  • If female, pregnant or breast feeding at the time of screening
  • For MRI study only: Claustrophobia or metal implants or paramagnetic objects contained within the body which may interfere with the MRI scan, as determined according to the guidelines set forth in the following reference book: "Guide to MR procedures and metallic objects" Shellock, PhD, Lippincott-Raven press, NY 1998
