1Departamento de Neurología, Hospital de Pediatría Juan P. Garrahan, Buenos Aires, Argentina.
Insights
This study highlights a specific childhood epilepsy syndrome with occipital spikes, characterized by vomiting and partial motor seizures. It also details its atypical evolutions and differential diagnoses, including rare genetic and acquired conditions.
Area of Science:
- Neurology
- Epileptology
- Pediatric Neurology
Context:
- Current classification of idiopathic localization-related epilepsies by the International League Against Epilepsy.
- Focus on a specific idiopathic epileptic syndrome in children.
Purpose:
- To summarize idiopathic localization-related epilepsies.
- To emphasize a distinctive syndrome featuring ictal vomiting, partial motor seizures, and occipital spikes.
- To discuss atypical evolutions and differential diagnoses.
Summary:
- Idiopathic localization-related epilepsies are classified, emphasizing a childhood syndrome with occipital spikes, ictal vomiting, and partial motor seizures.
- This syndrome, benign partial epilepsy of childhood with occipital paroxysms (BPECS), can evolve into continuous spike-and-wave during sleep (CSWS).
- Differential diagnosis includes cerebral palsy, structural brain pathologies, MELAS, and posterior cerebral calcifications with epilepsy and celiac disease.
Impact:
- Clarifies the diagnostic criteria and evolutionary patterns of specific childhood epilepsy syndromes.
- Aids clinicians in differentiating BPECS from other neurological conditions in children.
- Contributes to a better understanding of idiopathic epilepsies and their management.
Abstract:
Idiopathic localization-related epilepsies are summarized according to the current classification of the International League Against Epilepsy. The recognition of a distinctive idiopathic epileptic syndrome occurring in children and featuring ictal vomiting, partial motor seizures, and occipital spikes is emphasized. Atypical evolutions of benign partial epilepsy of childhood and status of BPECS. Acquired epileptic aphasia has also been correlated to BPECS, and all these syndrome (CSWS). Childhood epilepsy with occipital paroxysms may also evolve into CSWS and into clinical and EEG status. Differential diagnosis of BPECS includes children with fortuitous associations of BPECS with cerebral palsy and the occurrence of a clinicoelectroencephalographic phenotype of BPECS in children with progressive and nonprogressive structural brain pathologies. Childhood epilepsy with occipital paroxysms should be differentiated from cerebrovascular abnormalities mitochondrial myophathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS), and the syndrome of posterior cerebral calcifications, epilepsy, and celiac disease.
