Categorized into three groups:
Group | Characteristics | Conditions |
---|---|---|
Group I | Malformations resulting from abnormal proliferation of neuronal and glial cells | Microcephaly, macrocephaly, FCDs without and with balloon cells (Taylor dysplasia types IIa and IIb), hemimegalencephaly, tuberous sclerosis, dysembryoplastic neuroepithelial tumors (DNETs), gangliogliomas, gangliocytomas |
Group II | Malformations resulting from abnormal neuronal migration | Lissencephaly, heterotopias |
Group III | Malformations resulting from abnormal cortical organization | Polymicrogyria, schizencephaly, type I FCDs, mild MCDs |
