Outcome Measures

Primary Outcomes (1)

  • Comparison of mentalization abilities, in a population of patients with NT1 versus a control group.

    Scores obtained for the two sub-dimensions of the Reflective functioning questionnaire (RFQ) scale: RFQc and RFQu

    During the inclusion visit

Secondary Outcomes (4)

  • Comparison and description of mentalization abilities in a population of patients versus controls.

    During the inclusion visit

  • Better characterization of the clinical impression of an altered subjective experience of the difficulties the patients are going through.

    During the inclusion visit

  • Determination of the existence of a correlation between the time of appearance of the first symptoms and the initiation of treatment and the level of mentalization in NT1 patients, or not.

    During the inclusion visit

  • Determination of the existence of a correlation between the age at the first symptoms of NT1 patients and mentalization abilities, or not.

    During the inclusion visit

  • Adult patient having been diagnosed with type 1 narcolepsy according to ICSD 3 criteria and the completion of a 48-hour polysomnography at the Sleep Laboratory
  • Patient affiliated to or beneficiary of a social security system
  • For the control group:
  • Patient over 18 years old
  • Patient followed at Toulouse University Hospital and treated for Obstructive sleep apnea (OSA) with a residual AHI \<5/h, demonstrating the absence of residual OSA under treatment
  • Patient affiliated to or beneficiary of a social security system

You may not qualify if:

  • Patient with a history of autism spectrum disorder, chronic psychotic disorder, or bipolar disorder.
