title: Preoperative clinical evaluation and noninvasive electroencephalogram in cortical dysplasia.
abstract: The preoperative evaluation of patients with suspected cortical dysplasia involves detailed neurologic and neuropsychologic evaluations, electroencephalography, and comprehensive neuroimaging and functional studies. The goal is to identify a focal region of seizure onset and to assess for motor impairments, speech and language difficulties, or developmental delay. Although the electroencephalogram abnormalities in cortical dysplasia are nonspecific, they typically include unusual high-amplitude (slowing and focal) activity. The association of cortical dysplasia with cardiovascular, dermatologic, and other systemic disorders is discussed.
