Brain abnormalities in patients with schizophrenia identified

Posted on July 9, 2015

Scientists at more than a dozen locations across the United States and Europe analyzed brain MRI scans from 2,028 schizophrenia patients and 2,540 healthy controls, assessed with standardized methods at 15 centers worldwide. The findings, published in Molecular Psychiatry, help further the understanding of the mental disorder.

The team found individuals with schizophrenia have smaller volume in the hippocampus, amygdala, thalamus, nucleus accumbens and intracranial space than controls, and larger pallidum and ventricle volumes. The study validates collaborative data analyses can be used across brain phenotypes and disorders, and encourages analysis and data-sharing efforts to further understanding of severe mental illness.

The next step in this research is to compare the effects across disorders, to identify which brain region is the most affected in which disorder, and to determine the effects of age, medication, environment and symptom profiles across these disorders. "There's the increased possibility, not just because of the massive datasets, but also because of the collaborative brain power being applied here from around the world, that we will find something real and reliable that will change how we think about these disorders and what we can do about them," Turner said.
