Brief Summary

An exacerbated response to stress mediated by activation of the Hypothalamo-Pituitary-Adrenocortical (HPA) axis is thought to play an important role in the onset, worsening and relapse of schizophrenia. Subjects at risk for schizophrenia (unaffected siblings of patients) displayed an intermediate hyperreactivity to stress as compared with patients and healthy controls. Symptoms of schizophrenia can be reduced with noninvasive brain stimulation (NIBS) applied over the dorsolateral prefrontal cortex (DLPFC). Importantly, this same DLPFC NIBS protocol can modulate decision making processes and modulate biological reactivity to stress by decreasing salivary cortisol concentration in acute stress condition.

Eligibility Criteria

Age18 Years - 30 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Subject to genetic risk of schizophrenia, related first-degree schizophrenic patient
  • Man and woman
  • Age between 18 and 30 years old

You may not qualify if:

  • Contraindications to the practice of the tDCS, for safety measure, we will use the same contraindications as the practice of the Magnetic resonance imaging

Masking Details
The subject will be blind of the treatment he receives (active or placebo). \- The experimenter will also be blinded from stimulation (active or placebo) Each subject will be assigned a randomization code, corresponding to the code to enter the tDCS device. This system allows the person who administers tDCS and the subject receiving the stimulation to be blind .
Purpose
BASIC SCIENCE
Intervention Model
PARALLEL
Model Details: In a randomized controlled double blind study, 30 subjects, first-degree relatives of schizophrenic patients, were randomly assigned to 2 groups. A group of 15 participants will receive 30 minutes of active tDCS (2mA, 30 minutes with the anode at the left DLPFC and the cathode at the right DLPFC); A group of 15 participants will receive 30 minutes of placebo stimulation. During this stimulation session, all participants will undergo a standardized stress test combining psychosocial stress and physical stress
