Which seizure type is most characteristic of Rolandic epilepsy?

• A. Focal seizures with unilateral face and speech involvement, often nocturnal; centrotemporal EEG spikes
• B. Generalized seizures
• C. Absence seizures
• D. Atonic seizures

Answer: (A)

Rolandic epilepsy is classically a focal seizure syndrome that starts in the face and oropharyngeal muscles and often affects speech. These events typically occur at night and reflect activity in the centrotemporal region of the brain. The EEG pattern that goes with this clinical picture is centrotemporal spikes, maximal over the Rolandic area. This combination—focal seizures with facial involvement plus nocturnal onset and centrotemporal spikes on EEG—is what makes this description characteristic of benign rolandic epilepsy.

In contrast, generalized seizures involve the whole brain from onset and don’t show this focal facial semiology with centrotemporal EEG spikes. Absence seizures produce brief episodes of impaired awareness with typical 3 Hz spike-and-wave EEG activity and lack focal facial motor features. Atonic seizures present as sudden loss of muscle tone rather than focal facial activity.
