Washington, Oct 27 (ANI): A new study, conducted by researchers at the Institute of Psychiatry (IoP), King's College London, suggests that abnormalities in the white matter of the brain appear to influence the development of schizophrenia.
The white matter of the brain consists of nerve fibres that connect parts of the brain and help regulate behaviour.
The normal brain develops in a back to front fashion, i.e. posterior regions mature first and the frontal lobes last.
Study authors Professor Phillip McGuire and Dr Sophia Frangou discovered that if there are very severe deficits in the white matter in these posterior (specifically parietal) regions, then schizophrenia develops early in adolescence.
As people grow older their deficits "migrate" in a back to front manner and in adulthood, they impact the frontal lobes of the brain quite dramatically.
"Although we can trace the origins of schizophrenia to early brain development we still do not know what triggers the onset of the full blown symptoms. Our study suggests that at least part of the answer lies in problems affecting the "wiring" of key brain areas," McGuire said.
The team used Diffusion Tensor Imaging, a state-of-the-art neuro-imaging technique, to examine white matter connections in adolescents and adults with schizophrenia.
Abnormalities in white matter appeared first in posterior parts of the brain in the younger patients and became more prominent in the frontal lobes in adult patients.
In interpreting the results, Dr. Kyriakopoulos, the lead author, explained that the scans capture the interaction between brain development and disease mechanisms.
Dr Frangou on the value of this research: "We believe this study is unique as it approaches schizophrenia research from a new perspective. It takes a life-long view on schizophrenia and thereby bridges traditional barriers between child and adult patients."
The study adds new insight to mounting evidence that abnormalities in white matter play a critical role in what turns schizophrenia on and may provide clues to new treatments.
The study has been published in this month's edition of the British Journal of Psychiatry. (ANI)
