Brain Stimulation for Schizophrenia
N/A
Recruiting
Research Sponsored by University of California, Davis
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Be between 18 and 65 years old
Timeline
Screening 3 weeks
Treatment Varies
Follow Up assessment will begin immediately following stimulation and last for about 1.5 hours.
Summary
This trial is studying how well transcranial direct current stimulation (tDCS) works in improving higher-order cognition in people with and without schizophrenia.
Who is the study for?
This trial is for adults with schizophrenia, schizophreniform or schizoaffective disorder who have stable mental health, no recent medication changes, and a normal IQ. They must not be on clozapine, pregnant, have uncorrected vision issues that affect testing or skin conditions at electrode sites. Participants should not have substance abuse history in the last month or metal implants.
What is being tested?
The study tests how brain function related to higher-order cognition (like language comprehension and memory) is affected by transcranial direct current stimulation (tDCS). It compares the effects of tDCS on different brain regions using behavioral tasks and EEG monitoring in both healthy individuals and those with schizophrenia.
What are the potential side effects?
Potential side effects from tDCS may include discomfort at the electrode site, itching, tingling during application, headache after treatment sessions, fatigue or nausea. Serious risks are rare but can include seizures or skin burns.
