Evaluation of Stress Sensitivity and Hyperemotivity in Epilepsy Compared to and a Group of Healthy Volunteers (STELLA)
Evaluation of Stress Sensitivity and Hyperemotivity in Temporal Lobe Epilepsy With Enlarged Amygdala Compared to Epilepsy Without Enlarged Amygdala (Temporal and Extra-temporal) and a Group of Healthy Volunteers: Pilot Study.
Study Overview
Detailed Description
TLE-AE could concern 16 to 64 % of the TLE with "negative" MRI (Beh et al., 2016).
TLE-AE patients may suffer from anxiety and depression (Lv et al, 2014). In clinical practice, it has been also identified an emotional vulnerability in these patients, as they report more frequently a high sensitivity to emotional distress than other epileptic patients. They also report a change in their affect intensity or a hyperemotivity, which appeared at the onset of their epilepsy. Lanteaume et al. have linked some TLE with an increased emotional vulnerability (Emo-TLE): these TLE patients reported stress factors precipitating their seizures. They found that the Emo-TLE group was characterized by an attentional bias toward threatening stimuli versus neutral stimuli, and that this bias was noticed neither in the TLE group without emotional vulnerability nor in healthy volunteers. But they did not study amygdala structure in each group.In the large database of the Toulouse University Hospital, screening was done to retrospectively collect TLE patients with AE identified on MRI. This large database has served to establish a reading grid in order to help the visual identification of an AE.The investigators propose to these patients them a series of validated scales to test:
- The impact of emotional stress factors for precipitating seizures
- The perception of stress (PSS-10).
- Psychiatric comorbidities (anxiety, depression, post-traumatic stress disorder, emotional lability…).
The study also propose cognitive tasks to search for an attentional bias towards threatening stimuli (Emotional Stroop and modified probe test). After this, the study will assess their emotional subjective responses (valence, arousal, avoidance) through a task during which they are presented with short movies that elicit six different emotions. At the same time, the measure of the variations of their neurovegetative system in terms of blood pressure, heart rate variability and electrodermal skin conductance variability will be done.
For each TLE-AE patient, additional healthy controls will be matched (2 for testing the primary outcome, 3 for the secondary outcomes).

Score of The Clinical-administered PTSD Scale (CAPS)
Time Frame: 30 minutes
|
The clinical post-traumatic stress disorder scale (CAPS: Clinical-administered PTSD Scale) is the gold standard for diagnosing Post-Traumatic Stress Disorder (PTSD).
To pass the entire questionnaire, it takes about sixty minutes.
For the scoring list of milestones, it takes about 5 minutes.
The CAPS is the only questionnaire that provides information on both the frequency and intensity of symptoms, with specific behavioral anchor points.

The Post-Traumatic Checklist Scale (PCLS) is a simple self-questionnaire of about 10 minutes measuring the three main sub-syndromes of post-traumatic stress disorder: repetition (items 1 to 5), avoidance ( items 6 to 12) and neurovegetative hyperactivity (items 13 to 17).
The scale is composed of 17 items, rated from 1 to 5.
There is a cut-off at ≥ 45 to diagnose post-traumatic stress disorder.
The validity of the French translation has been verified.
