Pitfalls in the diagnosis of new-onset frontal lobe seizures()

We reported the case of a young woman who received an antiepileptic drug after a first possible generalized tonic-clonic seizure with no clear inter-ictal epileptic paroxysms in the routine electroencephalogram. Her stereotypical movements decreased but did not disappear with treatment. Then a diagnosis of PNES was considered by neurologist after witnessing a stereotypical motor episode. While AED treatment was decreased and stopped, epileptic seizure frequency and severity increased with secondary generalized tonic-clonic seizures. Then she presented postictal psychotic features that combined with video-EEG findings led to the final diagnosis of new onset pre-frontal lobe epilepsy.
