NCT01778504
Background: \- Many psychiatric, behavioral, and developmental disorders are genetic. This means that they tend to run in families. Some begin in childhood, while others do not appear until adulthood. Researchers want to look at people of all ages who have these disorders that started in childhood. They will also look at relatives of people with these disorders. This information will allow doctors to learn more about childhood behavioral problems and how they are inherited. It may also help doctors treat those disorders. Objectives: \- To study the onset and treatment of childhood behavioral, psychiatric, and developmental disorders. Eligibility: * Individuals of any age who have a psychiatric, autism spectrum, or developmental disorder, or other behavioral problems. * Family members of individuals with the above disorders. This group may include parents, grandparents, siblings, aunts/uncles, cousins, and children. Design: \- Participants will be screened with a medical history and physical exam. They may have a psychiatric history with tests of thinking, judgment, and behavior. Brain imaging scans may be performed to look at brain function....
NCT07453108
Our studies on MRI (Magnetic resonance imaging) biomarkers in neuropsychiatric disorders rely on reference data from control subjects which are dependent from our scanner. Due to the upcoming replacement of our MR scanner, the investigators need to 'recalibrate' our current database by acquiring the same data on both the old and the new device from a small group of controls (n = 36 to 40). This will be combined with measures of cortical excitability using robotized TMS (transcranial magnetic stimulation) that will be combined to MRI biomarkers in forthcoming studies. Therefore, the primary objective of this biomedical trial is to collect MRI and physiological measurements in normal subjects whose characteristics match to our study populations.
NCT02523742
Recently, we have shown functional resonance imaging (fMRI) that variations in signal induced by a language task were significantly lower in a semantic region of the left hemisphere (comprised of that part pars triangularis of the inferior frontal gyrus and the temporal gyri medium and angular) in schizophrenic patients compared with controls matched for age, sex, level of education and handedness. Investigators wish to test the hypothesis that functional modification of the hemispherical specialization is specific language and also specific for schizophrenia.
