Disorganized Cortical Patches Suggest Prenatal Origin of Autism
NIH Press Release NIH-funded Study Shows Disrupted Cell Layering Process in the Developing Brain The architecture of the autistic brain is speckled with patches of abnormal neurons, according to research partially funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health. Published in the New England Journal of Medicine on March 27, 2014, this study suggests that brain irregularities in children with autism can be traced back to prenatal development. “While autism is generally considered a developmental brain disorder, research has not identified a consistent or causative lesion,” said Thomas R. Insel, M.D., director of NIMH. “If this new report of disorganized architecture in the brains of some children with autism is replicated, we can presume this reflects a process occurring long before birth. This reinforces the importance of early identification and intervention.”
