Resumen:

Characterized as a prevalent sleep disorder, Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) is linked to cognitive deficits that impact attention, memory, learning, and executive functions. OSAHS can lead to elevated levels of carbon dioxide (CO2) in the blood, a condition known as Hypercapnia, which further contributes to cognitive impairment and results in slower EEG activity measured in polysomnography studies. In this study, we explore changes on EEG from recordings during a Stroop test realization on awake subjects to evidence effects of bad sleep hygiene. We compared OSAHS patients (with and without Hypercapnia) to healthy individuals, aiming to understand changes on EEG patterns with severity of OSAHS condition. Simultaneously, we evaluate patients identification between OSAHS patients and a Control group by using features extracted from EEG band power analysis. Assessment of identification was conducted using various algorithms; however, the support vector machine (SVM) stands out, achieving the best performance with an Area Under the ROC Curve (AUC) of 0.9031 and an accuracy (ACC) of 0.7933. Findings show that changes on EEG waves are present even on patient's vigil that could be an indicator of OSAHS impact. An opens possibility to use this features as biomarkers for OSAHS evaluation obtained during patient wakeful time and not only in polysomnography studies. © 2023 IEEE.
