type 1 narcolepsy

type 2 narcolepsy

idiopathic hypersomnia

In addition to the usual care, the patient will complete the following validated questionnaires :

SART (Sustained Attention to Response Task), IGT (Iowa Gambling Task), UPPS (Impulsive Behaviour Scale), TAS (Toronto Alexithymia Scale), BES (Basic Empathy Scale), FRET (Facial Emotions Recognition Task), ERF-CS, MASC (Movie for the Assessment of Social Cognition)

SART is Sustained Attention to Response Task. The Sustained Attention to Response Task (SART) is a computer-based go/no-go task that requires participants to withhold behavioral response to a single, infrequent target (often the digit 3) presented amongst a background of frequent non-targets (0-2, 4-9). There is evidence supporting the role of the SART as a measure of working memory, sustained attention, and impulse/inhibitory control.

The Iowa gambling task (IGT) is a psychological task thought to simulate real-life decision making. Participants are presented with four virtual decks of cards on a computer screen. They are told that each deck holds cards that will either reward or penalize them, using game money. The goal of the game is to win as much money as possible. Net scores are calculated as follow: [advantageous decks (C + D) minus disadvantageous decks (A + B)] for five blocks of 20 selections.

UPPS (Impulsive Behaviour Scale). The Impulsive behavior scale (S-UPPS-P) is an instrument composed of 20 items rated on a four-point Likert scale (23): (1) disagree strongly, (2) disagree some, (3) agree some, and (4) agree strongly. Scores are presented for each of five subscales, plus a total impulsivity score. In addition to the raw scores, in order to put each subscale into the same metric, the mean is calculated for the items on each subscale, from 1 to 4, where 1 indicates that the respondent did not indorse impulsive answers, and 4 indicating a high level of self-reported impulsivity.
