Emotions in Multiple Sclerosis
Emotions in Multiple Sclerosis
Through this study, a group composed of multiple sclerosis patients will be compared to a
 healthy volunteers group to determine if the positive emotions recognitions is preserved in
 the first group.
Different studies have highlighted the specific deficiency concerning emotions recognition in
 multiple sclerosis. Patients with multiple sclerosis are reported to have more difficulty
 recognising negative emotions, especially anger and fear.

 In this context, RECODE study has a twofold objective:

 -  To determine whether the positive emotions recognition remains preserved by combining
 behavioural and neurophysiological measures (electrodermal activity).

 -  To study this disorder's etiology through a comparison between a multiple sclerosis
 patient group and a control group (matched in sex, age, and education's level).
