Introduction: Frontal lobe seizures are the most commonly type of epileptic seizures misdiagnosed as non-epileptic events, namely those of psychiatric origin. Often epileptic and non-epileptic seizures co-exist in one patient. Case report: A teenager girl was admitted for the evaluation of episodes that started with paresthesia that was followed by sustained postures of her left limbs, sometimes with some jerky movements. She had previously been studied at a Psychiatric Hospital, where she had also shown some behavioural disturbances. Interictal EEG recording was normal, but a seizure originating from the frontal central area was documented. Brain MRI was normal. She had an excellent response to carbamazepine, with no further seizures since then. Conclusion: Frontal lobe epilepsy is often difficult to diagnose due to some bizarre ictal manifestation. Interictal EEG is often normal; even the ictal surface EEG can be of little value, because of the many artefacts that usually occur. Besides this, video-EEG is the best value exam for the diagnosis.
