Group/Cohort | Intervention/treatment |
---|---|
Healthy
40 healthy subjects, during quiet breathing and under an inspiratory load (inspiratory threshold loading)
|
Other: Neuropsychological tests
A battery of tests to evaluate the overall cognitive performance of the subjects (memory, executive, attentional or instrumental functions) |
Ondine syndrome
12 patients presenting with central hypoventilation syndrome or Ondine's curse syndrome, during spontaneous breathing and with Non Invasive Ventilation
|
Other: Neuropsychological tests
A battery of tests to evaluate the overall cognitive performance of the subjects (memory, executive, attentional or instrumental functions) |
Amyotrophic Lateral Sclerosis
30 patients presenting with Amyotrophic Lateral Sclerosis during spontaneous breathing and with Non Invasive Ventilation
|
Other: Neuropsychological tests
A battery of tests to evaluate the overall cognitive performance of the subjects (memory, executive, attentional or instrumental functions) |
- Score at PASAT (Paced Auditory Serial Addition Test) [ Time Frame: 3 hours ]Performances will be assessed by counting the number of good and wrong answers, and comparing it in two conditions : spontaneous breathing (SB) versus inspiratory resistive loading for healthy subjects, and SB versus non invasive ventilation for patients.
- Oxygen saturation changes [ Time Frame: 3 hours ]Modifications of oxygen saturation measured using a saturometer placed on the subject's finger.
