Our purpose was to compare the prevalence and characteristics of six basic emotions (disgust, happiness, fear, anger, surprise, sadness) during temporal lobe seizures (TLS). Three independent observers reviewed presurgical video-EEG recordings of 140 seizures, in 45 patients with drug-resistant temporal lobe epilepsy. We analyzed the ictal modifications of the facial expression suggesting emotions (FEE) - the pattern of facial activation underwent FACS (Facial Action Coding System) analysis-, the presence of a related coherent emotional motor or acoustic behavior, of a subjective feeling and of concomitant automatisms. Emotional facial expressions were present in 93 seizure (66%) and in 37 patients (82%). Negative emotions, particularly disgust and fear, were most represented. Right-sided ictal discharge was observed more frequently. Association of FEE with emotional motor/acoustic behaviors occurred in 21% of seizures and in 13% an emotional experience was referred. In conclusion, in temporal lobe epilepsy we observed a high incidence of emotional facial expressions. All the six fundamental emotions were represented, with prevalence of disgust and fear. Most part emotions were observed in right temporal seizures. The association of ictal display of emotions and complex eupraxic behavior support the hypothesis of the involvement of a wide physiological network including pre-frontal, fronto-mesial and temporal limbic structures. Gender dimorphism in referring some negative emotions, especially fear and rage, could reflect either inborn or socio-behavioral differences.
