The mechanisms of ventricular enlargement in schizophrenia is unknown. We identified that progressive ventricular enlargement is associated with deceleration of motile ci...

In conclusion, by investigating memory processes on longer delays than standardized memory tasks, we identified deficits in long-term memory consolidation leading to ALF in 22q11.2DS. Nevertheless, we showed that a subgroup of patients had larger memory consolidation deficit associated with lower intellectual functioning, higher rates of positive psychotic symptoms and hippocampal alterations.

Preclinical and clinical data reveal substantial ...

FINDINGSAn international study led by researchers from the Jane and Terry Semel Institute for Neuroscience and Human Behavior at UCLA has found that people who are born with a genetic disease that greatly increases the risk of developing schizophrenia  have distinctive defects and deficiencies in the white matter of their brains. Researchers compared the brains of people with the genetic disorder, 22q11.2 deletion syndrome, to the brains of healthy people and to the brains of people with the disease who do not have schizophrenia.The brain ’s white matter connects different regions of the brain and...

AbstractBackgroundThe 1.6 Mb 3q29 deletion is associated with neurodevelopmental and psychiatric phenotypes, including increased risk for autism spectrum disorder (ASD) and a 20 to 40-fold increased risk for schizophrenia. However, the phenotypic spectrum of the deletion, particularly with respect to ASD, remains poorly described.MethodsWe ascertained individuals with 3q29 deletion syndrome (3q29Del, “cases,”n = 93, 58.1% male) and typically developing controls (n = 64, 51.6% male) through the 3q29 registry (https://3q29deletion.patientcrossroads.org). Self-report of neuropsychiatric...
