Some synonyms for polymicrogyria include microgyric encephalopathy, microgyria, and microgyric cortex. Other terms used to describe this condition include cobblestone cortex, gyral disorganization, and cortical dysplasia. Though it is a rare condition, polymicrogyria is a serious medical condition that can have a profound impact on an individual's life and development. If you suspect that you or a loved one may have polymicrogyria, it is essential to seek medical attention promptly to receive an accurate diagnosis and appropriate treatment.
