The Correlation between the Cognitive Function and Speech Recognition Ability in Young OSAHS Patients / 听力学及言语疾病杂志

ABSTRACT

Objective To study the relationship between the cognitive function and speech recognition ability in young patients with OSAHS.Methods We selected 60 young male patients,according to the apnea-hypopnea index(AHI)and the severity of hypoxemia.They were divided into three subgroups on the basis of their syndrome severitiesmild group (n= 19;AHI 5~15/h,85%≤minimum SaO2≤90%),moderate group (n= 20;AHI>15~30/h,80%≤minimum SaO230/h,minimum SaO2<80%).First,we used the MoCA scale for cognitive function tests and recorded the scores.Then 15 lists of sentence Mandarin Speech Test Materials(MSTMs)were utilized to test each group.A data analysis was performed using SPSS 17.0 software. Results The total MoCA scores(mild group27.32±1.16;moderate group25.85±1.23;severe group24.52± 1.69;control group28.52 ±1.16)decreased progressively as the disease severity increased,showing significant differences between the control group and the mild,moderate and severe groups of OSAHS patients (allP<0.05). When sound stimuli were presented at 22,24,and 26 dB SPL,the speech recognition rates in the patients with se-vere(35.4±22.6,56.3±23.9,75.2±16.5)lower than the other groups (mild group38.4±23.5,58.3±25.5,79.2 ±18.5;moderate group38.8±21.6,58.7±22.7,78.5±16.7;control group39.4±23.5,60.3±24.3,80.2±16.4, respectively,allP<0.05).The differences in intensity of 50% recognition rate between the severe group(4.15± 0.80)and the control(3.62±0.41),mild (3.66±0.50)and moderate groups(3.72±0.55)of OSAHS patients were statistically significant(allP<0.05).Conclusion With hypoxia and disease severity increased,speech recogni-tion abilities in OSAHS patients decreased.This may be an important factor associated with cognitive assessment scale score.
