Summary

Story summary

A study using 7 Tesla magnetic resonance spectroscopy found significantly higher glutamine (Gln) levels in the thalamus and right temporoparietal junction of adults with Autism Spectrum Disorder.
In ASD group, elevated Gln levels correlated negatively with sensory sensitivity and sensation avoiding scores.
The Gln/Glu ratio was higher in the ASD group, indicating potential dysregulation in excitatory neurotransmission.
The study notes a cross-sectional design and limitations in using gold-standard diagnostic tools.
