Scientists Identify Overgrowth of Key Brain Structure in Babies Who Later Develop Autism

Autism is a neurodevelopmental disorder that affects communication, social interaction, and behavior. It is estimated that one in every 54 children in the United States is diagnosed with autism spectrum disorder (ASD). While the exact causes of autism are still unknown, researchers have been studying the brain structure of children with autism to better understand the disorder. In a recent study, scientists have identified an overgrowth of a key brain structure in babies who later develop autism.

What is Autism Spectrum Disorder?

Autism Spectrum Disorder (ASD) is a developmental disorder that affects communication, social interaction, and behavior. The symptoms of autism can range from mild to severe and can include difficulty with social interaction, repetitive behaviors, and difficulty with communication. Autism is typically diagnosed in early childhood, and the symptoms can persist into adulthood.

The Study

In a recent study published in the journal Nature Communications, researchers from the University of California, San Diego, and the University of North Carolina at Chapel Hill examined the brain structure of infants who were at high risk of developing autism. The researchers used magnetic resonance imaging (MRI) to scan the brains of 106 infants at six, 12, and 24 months of age.

The Findings

The researchers found that the infants who later developed autism had an overgrowth of the amygdala, a key brain structure that is involved in emotion processing and social behavior. The overgrowth was evident as early as six months of age and persisted through 24 months of age. The researchers also found that the overgrowth was more pronounced in boys than in girls.

Implications

The findings of this study have important implications for the early detection and treatment of autism. Early detection of autism is crucial for effective treatment, and the overgrowth of the amygdala could serve as a biomarker for early detection. The researchers also suggest that the overgrowth of the amygdala could be a target for early intervention and treatment.

Conclusion

Autism is a complex disorder that affects communication, social interaction, and behavior. While the exact causes of autism are still unknown, researchers have been studying the brain structure of children with autism to better understand the disorder. In a recent study, scientists have identified an overgrowth of a key brain structure in babies who later develop autism. The overgrowth of the amygdala could serve as a biomarker for early detection and a target for early intervention and treatment.
