This review of literature published in the last twelve months set out to chart progress made in understanding anatomical and functional features in autism spectrum disorder (ASD). The authors searched databases for research findings in the neuroimaging of autism using a variety of Medline search terms
They found that techniques such as functional magnetic resonance imaging (MRI) which uses magnetic fields and radio waves to produce two- or three-dimensional images of brain structures DTI (Diffusion tensor imaging an MRI-based neuroimaging technique that allows visualisation of the brain’s white matter tracts have continued to improve upon early histological and structural imaging studies. Newer techniques, including computer-based learning methods have allowed the study of ASD as a disorder of connectivity, regional cerebral function and neural circuitry.
The findings of these studies have repeatedly shown brain regions and neural circuits implicated in symptoms of ASD to be abnormal in individuals with a diagnosis of ASD.
The authors conclude that these findings provide a clear background for clinicians in the field of neuroimaging of ASD which have generated insights into the neurobiology of ASD.
