Brief Summary

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

Excessive diurnal sleepiness is characterized by an incapacity to stay awake, in favour of sleep occurrence. This sleepiness might be secondary to a sleep disorder; when it is not the case, it is primary hypersomnia (including narcolepsy and idiopathic hypersomnia).

To date, objective measures of sleepiness can only be achieved in laboratory. Subjective techniques as scales and questionnaires are highly sensitive to inter-individual differences and cannot constitute a reliable diagnosis tool of sleepiness.

Recent studies suggested that some salivary biomarkers are sensitive to sleep characteristics and thus, may allow the objective and easy evaluation of sleepiness.

The objective of the study is to explore the usability of salivary biomarkers (a-amylase and oxalate) as a new non-invasive technique to evaluate sleepiness and to diagnose primary hypersomnia in children.

The hypothesis of this study is that there will be a modification of salivary biomarkers concentrations with the variations of diurnal sleepiness.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Children with primary hypersomnia

Children with primary hypersomnia, i.e. narcolepsy or idiopathic hypersomnia

saliva samples

Intervention Type BIOLOGICAL

Collection of salivary a-amylase during the day (5 times a day: at 8:00 am, 9:00 am,1:00pm, 4:00pm and 8:00pm) with Salivette.

Stanford sleepiness scale

Intervention Type BEHAVIORAL

The Stanford Sleepiness Scale evaluates sleepiness at the time of the evaluation. The subjects have to choose the statement best representing their level of sleepiness on a scale ranging from 1 to 7: the higher the score, the higher the sleepiness.

This scale will be submitted to the children before each salivary sampling (5 times a day: at 8:00 am, 9:00 am,1:00pm, 4:00pm and 8:00pm)

Karolinska Sleepiness Scale

Intervention Type BEHAVIORAL

The Karolinska Sleepiness Scale assesses the perceived level of sleepiness at the time of the evaluation on a 9-points scale. The higher the score, the higher the sleepiness.

This scale will be submitted to the children before each salivary sampling (5 times a day: at 8:00 am, 9:00 am,1:00pm, 4:00pm and 8:00pm)

Epworth Sleepiness Scale

Intervention Type BEHAVIORAL

The Adapted Epworth Sleepiness Scale for children in which the item "falling asleep while in a car stopped in traffic" was replaced by "falling asleep at school" assesses the risk of falling asleep in 8 daily-life situations estimated on a 4-point Likert scale. The total score is the sum of the scores for the 8 items: a higher score represents greater sleepiness and the pathological threshold is higher than 10.

This scale will be submitted to the children one time, at the onset of the hospitalization.

BLAST test

Intervention Type BEHAVIORAL

The BLAST (Bron/Lyon Attention Stability Test) is a computerized attention test evaluating brief lapses of attention with 4 measures: reaction times, errors and two composite measures (Stability and Intensity). The subjects have to detect the presence or the absence of a specific stimulus during approximatively 60 trials for 3 minutes. Normative data are available for both children and adults.

This test is part of the neuropsychological evaluation, conducted the afternoon of the first day of hospitalization. The test is realized at 4:00pm.

Children with secondary hypersomnia

Children with a secondary hypersomnia, i.e. caused by sleep deprivation, a psychiatric disorder, sleep fragmentation, circadian delay.

saliva samples
