Abstract

Although there is near-universal early-onset epileptic encephalopathy in cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD), it has been observed clinically that EEGs are initially only mildly abnormal and worsen in the first 2 years of life. This study aimed to identify specific EEG patterns, ictal and interictal, in individuals with CDD during the first 2 years of life and to explore their relationship with clinical and developmental outcomes.
