Signs and symptoms of pachygyria vary among affected people and can depend on the extent of the abnormality. They often include poor muscle tone and motor function; seizures; developmental delays; intellectual disability; failure to grow and thrive; difficulties with feeding or swallowing; swelling in the extremities; and small head size (microcephaly). Most infants appear physically normal, but some conditions associated with pachygyria cause distinctive facial or skull characteristics.
