Pediatric occipital lobe epilepsy: A modern review of etiological classification, management, and outcomes

Table 5 Differential diagnosis of occipital lobe epilepsy

Condition	Distinguishing features
Structural focal epilepsy	Requires brain MRI to exclude lesions (e.g., cortical dysplasia, tumors)
Migraine with aura	Visual phenomena are slower to develop, last longer (minutes vs seconds), and differ qualitatively (linear/zigzag vs circular colors)
Epilepsy with eyelid myoclonia (Jeavons syndrome)	Distinguished from POLE by prominent eyelid myoclonia and absence of visual hallucinations or head version
Celiac disease and calcification	Distinguished by occipital lobe calcifications visible on CT
Lafora disease	Presents with visual seizures but involves progressive cognitive impairment, myoclonus, and ataxia
Mitochondrial disease (e.g., MELAS)	Must be considered; often presents with other systemic or neurological signs

MELAS: Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes; POLE: Photosensitive occipital lobe epilepsy; CT: Computed tomography; MRI: Magnetic resonance imaging.
