ASD or autism spectrum disorder is quite commonly found in preschoolers these days. We can observe the abnormal connections formed between brain’s neural networks seen through special MRI technique. It has been stated by several journals, surveys and studies that finding treatment for ASD are crucial especially in initial ages of preschoolers. ASD is basically a developmental disorders group featuring difficulties like communication problems, limited activities or interests, and repetitive behaviors. While aging between 1 and 5 many children get to diagnose with ASD initially this is why early intervention and diagnosis are crucial. By this, the younger patient tends to get benefitted by several services and treatments, in order to improve their functional ability and symptoms.
It has been observed that there is an abnormal connectivity in younger children’s brain due to ASD and why such situation occurs is still a question and a matter of investigation. Many scientists are still trying to find that under what kind of developments brain imaging is enabling abnormal connectivity networks. Brain networks are known to be connected through white matter tract liable to interact for performing various functions. Many researchers used MRI techniques for analyzing why such differences are occurring in the brain due to ASD and after deep studies, they named it DTI stands for diffusion tensor imaging. This technique provides all crucial information concerned with the state of brain’s white matter.
After that, the researchers from some of the leading organizations like Centria Healthcare compared the result of DTI to twenty-one girls and boys who were preschoolers and had ASD. Among those 21 similarly aged children were with typical brain development. Then they applied the graph theory on DTI results so that they can clearly understand the connectivity level between the brain networks precisely. After applying graphing analysis on the DTI results, researchers had measured relationships among all the complex and highly connected data like connections’ networks accountable for forming human brain. On being compared to a consistently developed group, children with the ASD were demonstrated with the significant differences between basal ganglia network’s components. It is a brain system known to be playing an imperative role in human behavior. Apart from that, there were differences in the paralimbic-limbic network also which is another system diagnosed to deal with regulating the behavior.
Some specialists state that the altered connectivity in the brain can be a salient pathophysiological feature of ASD. That altered connectivity is liable to be visualized in humans’ findings providing additional steps in analyzing ASD. Several results have suggested that all these altered patterns will be underlying in the development of abnormal brain among preschool children who are having ASD. This can contribute to nervous system along with the brain mechanisms that are liable to be involved in the disorder. Furthermore, the labeling of altered structural connectivity among these networks can lead towards the potential biomarkers of imaging for the ASD having preschoolers. Finding the imaging of the pointed targets can become a clue for the further diagnosis. And not only that, it can also be a therapeutic intervention for preschoolers. For ASD therapies in children, repetitive TMS (transcranial magnetic stimulation) can be beneficial because it involves magnet usage to stimulate and target brain’s affected areas.
