Polymicrogyria (PMG) is a developmental malformation of the human brain characterized by an excessive number of small convolutions (gyri) on the surface of the brain. Either the whole surface or parts of the surface can be affected.
Polymicrogyria may in fact be just one piece of a syndrome of developmental abnormalities, because children born with it may suffer from a wide spectrum of other problems, including: global developmental disabilities, mild to severe mental retardation, motor dysfunctions including speech and swallowing problems, respiratory problems, and seizures. Each child is unique in their presentation of the disorder, thus it is difficult to make a predictable prognosis for children with the diagnosis of PMG.
