Ear-EEG detects ictal and interictal abnormalities in focal and generalized epilepsy -A comparison with scalp EEG monitoring

The incidence of temporal lobe epilepsy (TLE) has been estimated to 10.4/100.000 (Landino et al., 2014). It is the most common type of epilepsy among patients with refractory epilepsy referred to tertiary centers (Semah et al., 1998) and TLE represents the majority of cases considered for epilepsy surgery (Téllez-Zenteno and Hernández-Ronquillo, 2011). The delay from first seizure to referral to epilepsy surgery is generally more than a decade (Benbadis et al., 2003). It has been estimated that 5-23% of patients with TLE are misdiagnosed (van Donselaar et al., 2006), which may contribute to the delay.
