NCT03464370

Brief Summary

Recently, a possible subtype of temporal lobe epilepsy (TLE) has been proposed: this subtype presents ipsilateral amygdala enlargement (AE) without any other lesion. However, little is known about its clinical and psychiatric phenotype. The amygdala seems to play a major role in stress related disorders (including perception of stress). The hypothesis in this study is that patients with TLE-AE more frequently report emotional distress as a seizure-precipitating factor than any other epileptic patient.

Outcome Measures

Primary Outcomes (1)

  • Score on the scale of emotional seizure precipitant the outbreak

    It is a hetero-questionnaire, subjectively measuring the sensitivity of an epileptic patient to the stressors of daily life that may trigger or promote the onset of their seizures.

    30 minutes

Secondary Outcomes (9)

  • Score of The Emotional Stroop tasks

    30 minutes

  • Score of The congruency index

    30 minutes

  • Score of the Scale measures during the movie tasks

    30 minutes

  • Score of The Perceived Stress Scale 10

    30 minutes

  • Score of The Tyrer's brief Scale for Anxiety (BAS)

    30 minutes

  • +4 more secondary outcomes

Study Arms (4)

TLE-AE Group

EXPERIMENTAL

30 subjects Age between 18 and 65 case-control with 2 witnesses per sex and age matched cases (within 5 years) for the evaluation of the primary endpoint. For the secondary endpoints, 3 controls will be matched for each case on gender and age (within 5 years) Measure of emotional stressors then evaluate the traumatic events and to date them with respect to the beginning of epilepsy in different populations of epileptics.

Other: Measure of emotional stressors

Non AE epileptic Group

ACTIVE COMPARATOR

30 subjects Age between 18 and 65 case-control with 2 witnesses per sex and age matched cases (within 5 years) for the evaluation of the primary endpoint. For the secondary endpoints, 3 controls will be matched for each case on gender and age (within 5 years) Measure of emotional stressors then evaluate the traumatic events and to date them with respect to the beginning of epilepsy in different populations of epileptics.

Other: Measure of emotional stressors

Extra-temporal epilepsy Group

ACTIVE COMPARATOR

30 subjects Age between 18 and 65 case-control with 2 witnesses per sex and age matched cases (within 5 years) for the evaluation of the primary endpoint. For the secondary endpoints, 3 controls will be matched for each case on gender and age (within 5 years) Measure of emotional stressors and then evaluate the traumatic events and to date them with respect to the beginning of epilepsy in different populations of epileptics.

Other: Measure of emotional stressors

Interventions

For the Epileptic Group * Rapid interrogation, completing the clinical data * A scale of impact of the precipitating factors of crises * An emotional Stroop * A task of detecting emotional targets against threatening information * A measure of the perception of emotions using film clips * A scale of measurement of perceived stress * The transfer of psychiatric scales For the healthy volunteers group : * A rapid interrogation, gathering the possible medical history, the level of studies, the manual laterality * An emotional Stroop * A task of detecting emotional targets against threatening information * A scale of measurement of perceived stress * A measure of the perception of emotions using film clips * A rapid neuropsychological assessment
