Recent research from Harvard Medical School indicates that brain scans of fetuses could potentially identify the likelihood of a future Autism Spectrum Disorder (ASD) diagnosis. In a preliminary study, the team examined MRI brain scans of 39 fetuses at 25 weeks of gestation, identifying that nine of these children were later diagnosed with ASD. Notably, those diagnosed exhibited distinct differences in the temporal lobe compared to their peers.
The MRI scans revealed that the insular lobe, which is crucial for motor control, sensory processing, and social behavior, was larger in children who were later diagnosed with ASD. ASD is a complex condition characterized by difficulties in social interaction and communication, alongside repetitive behaviors and interests, as defined by the Association for Science in Autism Treatment. Additionally, the ASD group showed statistically significant enlargement of the amygdala, hippocampal commissure, and insula compared to non-ASD counterparts. The amygdala, located deep within the temporal lobe, plays a significant role in emotional regulation, particularly in response to fear.
Dr. Lily Montgomery, a postdoctoral fellow at the Martinos Center for Biomedical Imaging, highlighted that recognizing early brain anomalies in fetuses could be pivotal, as many genetic and environmental influences on ASD development begin during pregnancy. This study contributes to a growing body of evidence suggesting that ASD originates in early development, countering the discredited belief that vaccines or other environmental factors cause the disorder. “These findings underscore the importance of investigating these regions further to establish potential biomarkers,” Dr. Montgomery stated.
As of late 2021, approximately 1 in 44 children in the U.S. receives a formal ASD diagnosis each year. For more insights, you can check out this related post on home insemination kits here. For authoritative information on pregnancy, visit CDC’s pregnancy resources.
