Patients suspected of OSA who were scheduled for PSG were recruited. Cognition was assessed using the Montreal Cognitive Assessment (MoCA) and Color Trails Test (CTT). The Memory Index Score (MIS) was calculated from the MoCA. Subjective cognitive complaint presence was assessed through direct questioning of patients and by employing the Cognitive Change Index rated by self or informants (CCI\u2010I). Patients with severe dementia were excluded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 258 patients (mean age 61.46\u00a0\u00b1\u00a07.05\u00a0years, 51.2% female), the mean MoCA score was 23.89\u00a0\u00b1\u00a03.89. Based on PSG results, patients were categorized into groups as follows: those without OSA or with mild OSA (combined total of 20.1%), moderate OSA (28.3%), or severe OSA (51.6%). Cognitive Change Index rated by self and CCI\u2010I scores correlated significantly (\n                      <jats:italic>r<\/jats:italic>\n                      \u00a0=\u00a00.238,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.019) but not with the MoCA score or CTT time. Objective cognitive scores were associated with PSG parameters: total sleep time (TST), sleep onset latency, wake after sleep onset, sleep stages, mean O2 saturation, and time spent with SaO2 below 90% (all\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.05). Subjective cognitive scores were not associated with PSG parameters, except CCI\u2010I with TST. Participants with objective cognitive impairment had lower education, higher body mass index, more comorbidities, and lower SCC percentage (all\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.05). Patients with moderate to severe OSA had a higher proportion of objective cognitive impairment (64.1%) but a lower incidence of SCC (38.3%) than patients with no OSA or mild OSA. Thirty patients with severe OSA and cognitive impairment received continuous positive airway pressure (CPAP) treatment for a mean of 12.2\u00a0months. These patients showed MoCA and MIS improvement, but no significant changes were observed in their CTT and Cognitive Change Index scores.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Most patients with OSA had objective cognitive impairment, but SCC was less frequent in patients with more severe OSA.
