Brain Stimulation, Clinical Symptoms and Cognition
Transcranial Direct Current Stimulation (tDCS) Studies of Auditory Hallucinations, Negative Symptoms and Cognition in Schizophrenia
Source: ClinicalTrials.gov · Last updated 17 May 2024
Brief summary (registry, in English)
The purpose of this study is to test the impact of non-invasive brain stimulation, transcranial direct current stimulation (tDCS), on auditory hallucinations, negative symptoms and cognition in schizophrenia. Clinical measures will be used to assess clinical symptoms and cognitive performance to test the hypothesis that a course of tDCS can reduce auditory hallucinations and negative symptoms in schizophrenia.

Prior treatment
- Metallic implants
Other illness
- Skin damage or skin conditions such as eczema at the sites where electrodes will be placed

- Implanted electrical (brain and spinal) stimulators
- Implanted defibrillator
- Hair styles hindering the placement of electrodes
- Cranial pathologies
- Head trauma
- Mental retardation
- Uncorrected vision problems that would hinder cognitive testing (this also pertains to subjects with color blindness in tasks where discriminating colored objects/items is necessary for successful performance)

- Substance dependence in the past six months
- Substance abuse in the past month
Who the study is looking for
- Participants must be able to sufficiently speak and understand English so as to be able to understand and complete cognitive tasks.
- All subjects must have the ability to give valid informed consent.
- No children under the age of 18 will be recruited.
- Diagnosis of schizophrenia, schizophreniform, or schizoaffective disorder
- Stable outpatient or partial hospital status
- Normal IQ (\>70; IQ will be measured by administering the Wechsler Abbreviated Scale of Intelligence (WASI) test)
Age in the registry: 18 years to 65 years · Sex: All · Accepts healthy volunteers
