[The atypical developments of rolandic epilepsy are predictable complications]

Area of Science:

• Pediatric Neurology
• Epileptology
• Clinical Neurophysiology

Context:

• Rolandic epilepsy (RE) exhibits variable phenotypes, influenced by age and genetics.
• Atypical features in RE suggest a spectrum of underlying conditions.
• Understanding these atypical presentations is crucial for diagnosis and management.

Purpose:

• To investigate the electroclinical characteristics associated with atypical development in rolandic epilepsy.
• To identify specific EEG and clinical markers indicative of atypical RE phenotypes.

Summary:

• A retrospective study analyzed nine children with rolandic epilepsy exhibiting atypical features and electrical status epilepticus during sleep (ESES).
• Patients presented with early onset (average 5 years), clinical and EEG deterioration, and frontocentrotemporal EEG foci.
• Atypical benign focal epilepsy (ABFE) and continuous spike-wave during sleep (CSWS) were observed, alongside cognitive and behavioral deficits.

Impact:

• Identifies key electroclinical features for diagnosing atypical rolandic epilepsy.
• Highlights the association between ESES and atypical RE phenotypes.
• Emphasizes the need for early recognition of atypical RE to address associated learning and behavioral issues.
