Succinic semialdehyde dehydrogenase deficiency (SSADHD) is a rare inherited metabolic disorder caused by a defect of γ‐aminobutyrate (GABA) catabolism. Despite the resultant hyper‐GABAergic environment facilitated by the metabolic defect, individuals with this disorder have a paradoxically high prevalence of epilepsy. We aimed to study the characteristics of epilepsy in SSADHD and its concordance with GABA‐related metabolites and neurophysiologic markers of cortical excitation.
