Added diagnostic value of magnetoencephalography (MEG) in patients suspected for epilepsy, where previous, extensive EEG workup was unrevealing

Although epilepsy can be diagnosed solely on clinical data, additional investigations are often needed after the first seizure to assess the probability of recurring seizures (Fisher et al. 2014). EEG is one of the most important investigations, which besides supporting diagnosis of epilepsy, also contributes to its classification (Berg et al. 2010). It is well established that in about 10-20% of patients with epilepsy, multiple EEG studies including sleep deprived EEG, fail to show abnormalities (Alving and Beniczky.
