Risperidone increases the cortical silent period in drug-naive patients with first-episode schizophrenia: A transcranial magnetic stimulation study.

Objectives: Schizophrenia is accompanied by impaired cortical inhibition, as measured by several markers including the cortical silent period (CSP). It is thought that CSP measures gamma-aminobutyric acid receptors B (GABA) mediated inhibitory activity. But the mutual roles of schizophrenia as a disease and the drugs used for the treatment of psychosis on GABA mediated neurotransmission are not clear.

Repetitive transcranial magnetic stimulation reduces cigarette consumption in schizophrenia patients.

Introduction: High-frequency repetitive transcranial magnetic stimulation (rTMS) over the left dorsolateral prefrontal cortex (DLPFC) seemed to decrease tobacco consumption and craving in nicotine-dependent people without psychiatric disorder or otherwise healthy people. Even if the prevalence of cigarette smoking in schizophrenia patients is high and estimated to be between 45% and 88%, this technique has not been systematically studied in this indication in schizophrenia yet.

The Aim Of The Study: The aim of this study was to test the ability of high-frequency (10Hz) rTMS over the left DLPFC to decrease cigarette consumption in schizophrenia patients.

Psychometric properties of the Temperament and Character Inventory-Revised (TCI-R) in Czech adolescent sample.

The psychometric properties of the TCI-R method were investigated in a cohort of 15-year-old adolescents (n = 787). This is the lowest recommended age for using the adult version of the method. A factor analysis of the temperament and character scales was carried out on the basis of Principal Component Analysis with Varimax rotation.
