Agyria-pachygyria type 1


Agyria-pachygyria type 1 is an abnormal brain development where the brain fails to develop normally during the fetal stage.


  • Small brain
  • Mental retardation
  • Smooth brain
  • Spasticity
  • Seizure
  • Broad shallow brain gyre


Different imaging modalities are commonly used for diagnosis:

  • Computed tomography (CT) is a lower-resolution imaging modality available, however, cerebral cortex malformations are more easily visualized in vivo
  • classified using high-resolution magnetic resonance imaging (MRI) equipment


Because pachygyria is a structural defect no treatments are currently available other than symptomatic treatments, especially for associated seizures. Another common treatment is a gastrostomy (insertion of a feeding tube) to reduce possible poor nutrition and repeated aspiration pneumonia.
