Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective is to examine the potential mentalization impairments affecting a population suffering from narcolepsy type 1. Indeed, the hypothesis of this research is that mentalization could be impaired in narcoleptic patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Narcolepsy type 1 (NT1) is a rare and still poorly understood pathology which can have a significant impact on patient's daily life. Beyond the experience of their chronic illness, their feelings about the difficulties they go through during their lives seem relatively blunted, as if what could be described as restrictive could be acceptable for them. Moreover, the response generated by constraint, even if it is a refusal, rarely turns out to be impulsive or aggressive.

Rapid Eye Movement (REM) sleep is known to play a role in emotional regulation and also in narcolepsy. These processes both take place in hypothalamus, so, a link between them seems conceivable. Surprisingly, the studies about depression, impulsivity, addictions, facial emotional recognition in narcoleptic patients show results that differs from the expectations of the investigators, and can even be at the opposite. It appears difficult to have a clear idea of the mental state of narcoleptic patients.

Mentalization is a concept with a strong empirical base. It corresponds to ability to understand the mental state, of oneself or others, that underlies overt behaviour. The idea of this research is that this process is modified in narcoleptic patients.

The main objective is to examine the potential mentalization impairments affecting a population suffering from narcolepsy type 1. To realise this study a group of patients with NT1 and a control group will complete several questionnaires which are validated about mentalization and other ones. This combination of questionnaire is designed to evaluate the comparability of the groups and search for potential confounding factors.
