The social processes depend on complex cognitive mechanisms, which involve mainly the frontal and temporal lobe regions. Patients with early onset frontal and temporal lobe lesions might later develop important deficits in social integration. Accordingly, children with early onset temporal lobe epilepsy (TLE) demonstrate altered emotion recognition.
Study design: Multicentre, Case-control study. Emotion recognition is a first step for the development of the capacity to judge the thoughts, intentions, and desires of others. In infants, the capacity to identify, distinguish, and interpret emotions is limited, but these processes are developing rapidly and innately during the first years of life, on the same neural bases as those described in adulthood. Children with BECTS show altered social behavior. In fact, deficit in social cognition could derive from brain dysfunction in the frontotemporal regions primarily affected in BECTS, since these regions are also viewed as playing an important role in social cognition and development of social skills. The investigators hypothesized that children with BECTS might have altered social cognitive skills and underlying neural networks.
Study Type
OBSERVATIONAL
Enrollment
200
Five pictures (including nonfacial features; i.e., hairs) were used for each emotion, giving a total of 25 trials.Stimuli consist of pictures of facial affect taken from the Ekman and Friesen series.
IRCCS Neuromed
Pozzilli, Isernia, Italy
RECRUITINGNumber (total amount) of errors in facial emotion recognition
A neuropsychologist will sign the number of errors in recognizing each facial emotion expression
Time frame: an average of 1 year
Rating of the intensity of facial expressions
A neuropsychologist will ask the subjects to rate (on a scale from 0 = not at all to 5 = very much) each stimulus with respect to the prototypical expression of that emotion
Time frame: an average of 1 year
Rating of the arousal of facial expressions
A neuropsychologist will ask the subjects to evaluate arousal in terms of feeling of high-low energy/wakefulness/alertness by rating each stimulus on a 9-point scale.
Time frame: an average of 1 year
Rating of the valence of facial expressions
A neuropsychologist will ask the subjects to evaluate valence in terms of feeling of high-low pleasantness-unpleasantness by rating each stimulus on a 9-point scale.
Time frame: an average of 1 year
EEG abnormality lateralization and facial emotion recognition
The investigators will include in statistical analysis the side (dominant hemisphere vs. non-dominant) of EEGraphic abnormalities on awake/sleep recordings
Time frame: an average of 1 year
