This observational study aims to evaluate multiple dimensions of health in patients with Obstructive Sleep Apnea Syndrome (OSAS), before and after three weeks of ventilotherapy.
Specifically, the study aims to identify pre- vs post-treatment differences in the following domains:
Thus, patients will complete the following evaluations before (T0) and after (T1) ventilotherapy:
Obstructive Sleep Apnea Syndrome is associated with cognitive difficulties, low psychosocial wellbeing and quality of life; however, the possible beneficial contribution of ventilotherapy on these dimensions is not completely clear. Ventilotherapy restores brain oxygenation and improve rest, possibly increasing cognitive performances, psychosocial health and quality of life. Multidisciplinary approaches to the treatment of OSAS are rare, although recommended. Solid proof of OSAS comorbidities may encourage clinicians to adopt a holistic perspective of care, leading to better rehabilitative outcomes. Also, evidence of the beneficial effects of ventilotherapy could increase patients' compliance to ventilotherapy, which is generally low.
The study aims to evaluate multiple dimensions of patient's health before and after three weeks of ventilotherapy, focusing on the cognitive performance, the blood expression of biomarkers related to neurodegeneration, and individual's psychosocial wellbeing.
Overall, it is expected improved cognitive performances and psychosocial wellbeing after ventilotherapy. Also, a reduction in the blood expression of biomarkers related to neurodegeneration (if found before the treatment) is hypothesized, although the limited research in this field requires cautious predictions.
Comprehensive evidence about OSAS comorbidity, beyond breath and sleep difficulties, is mandatory to design innovative multidisciplinary rehabilitative approaches in line with a holistic perspective of care. Effective multidisciplinary approaches are considered the gold standard in medical care, leading to better treatment outcomes and higher patients' satisfaction.
Beyond the clear ethical implication of providing higher quality of treatment, multidisciplinary interventions also imply a shared responsibility of treatment, preventing from clinical misjudgments and professionals' burnout.
