Slowing may be intermittent or persistent, with more persistent or consistently slower activity generally indicating more severe underlying focal cerebral dysfunction. (A) Axial FLAIR image four years before diagnosis of FCDIIb was established shows no evidence of cortical dysplasia, heterotopia, mass lesion or vascular lesion. Epilepsy secondary to focal cortical dysplasia (FCD) usually begins early in life, is often refractory to antiepileptic drug (AED) therapy, and a frequent cause of focal motor status or focal epilepsy, which may be life-threatening (Desbiens et al., 1993).
