However, some children may present with independent autonomic seizures or seizures with mixed Rolandic-autonomic manifestations including emesis as in Panayiotopoulos syndrome.Atypical forms:  Rolandic epilepsy may present with atypical manifestations such early age at onset, developmental delay or learning difficulties at inclusion, other seizure types, atypical EEG abnormalities.These children usually have normal intelligence and development. Learning can remain unimpaired while a child is afflicted with Rolandic epilepsy. Cause
Benign epilepsy with centrotemporal spikes is thought to be a genetic disorder. An autosomal dominant inheritance with age dependency and variable penetrance has been reported, although not all studies support this theory. Linkage studies have pointed to a possible susceptibility region on chromosome 15q14, in the vicinity of the alpha-7 subunit of the acetylcholine receptor. Most studies show a slight male predominance. Because of the benign course and age-specific occurrence, it is thought to represent a hereditary impairment of brain maturation.An association with ELP4 has been identified. Diagnosis
The diagnosis can be confirmed when the characteristic centrotemporal spikes are seen on electroencephalography (EEG). Typically, high-voltage spikes followed by slow waves are seen. Given the nocturnal activity, a sleep EEG can often be helpful. Technically, the label "benign" can only be confirmed if the childs development continues to be normal during follow-up. Neuroimaging, usually with an MRI scan, is only advised for cases with atypical presentation or atypical findings on clinical examination or EEG.
