Structural Brain Abnormalities Linked to Schizophrenia

That is the title of the article I am writing about. "A collaborative international study has discovered that individuals diagnosed with schizophrenia often have smaller brain regions than people without mental illness. The finding provides a clue into how the condition may develop and respond to treatment. In the study, 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.
The findings, which experts believe will help to advance improved understanding of the mental disorder, appear in the journal Molecular Psychiatry. The work was the product of the Enhancing Neuroimaging Genetics through Meta-Analysis project (ENIGMA), from the Schizophrenia Working Group. The Group is co-chaired by Dr. Jessica Turner, associate professor of psychology and neuroscience at Georgia State University, and Dr. Theo van Erp, assistant research professor in psychiatry at the University of California, Irvine." This is very interesting because it can find out why I lose some of the knowledge I had before this disease.  Maybe they can find out and stop it from happening this could really help.
The article goes on to say: "'This is the largest structural brain meta-analysis to date in schizophrenia, and specifically, it is not a meta-analysis pulled only from the literature,' said Turner.  'Investigators dug into their desk drawers, including unpublished data to participate in these analyses.  Everyone performed the same analyses using the same statistical models, and we combined the results. We then identified brain regions that differentiated patients from controls and ranked them according to their effect sizes.'  The team found individuals with schizophrenia have smaller volume in the hippocampus, amygdala, thalamus, nucleus, accumbens, and intracranial space controls, and larger pallidum and ventricle volumes.  The study demonstrates that collaborative data analyses can be used across brain phenotypes and disorders.  This approach encourages analysis and data-sharing efforts to further understanding of severe mental illness." Does it have anything to do with negative symptoms.  What does it cause and what medicines can come about because of this?
The article ends with: "The ENIGMA collaborations include working groups for others disorders such as bipolar disorder, attention deficit, major depression, autism and addictions, who are all doing these same analyses.  Researchers say the next step is to compare the effects across disorders, to identify which brain region is the most effected 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 data sets, 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." I really hope there is something that comes of this. I have questions such as do they find people who are about to be diagnosed with schizophrenia to see if the medications is causing this shrinking of the areas?  Can they stop it from happening.  What does it have to do with people taking medications and still having problems with this disease?

  3. Wow, Excellent post. This article is really very interesting and effective. thank you for share such kind of article. I think its must be helpful for us. Just watch it; Andrew awce Myland recently purchased the area at 39-47 Union St in Auckland. The site is large enough to accommodate up to three towers of apartments but that isn’t what is going to happen. Myland wants to do something more than just build a group of apartment buildings and shove everyone right next to each other. Instead, Fawcet and Myland want to build much higher standard of living with a lower density of residents.
