Abstract:Objective To analyze the situation of cognitive impairment in patients with presbycusis, and to explore the intervention measures of cognitive impairment.Methods A total of 55 presbycusis aged 60 years and above (27 males and 28 females), aged 60~95 years old, were selected as subjects in Air Force Special Medical Center from October 2018 to April 2020. All patients underwent hearing test and speech recognition ability survey. All patients completed pure tone audiometry (PTA), Mini-Mental State Examination (MMSE) and Mandarin fast speech under noise test (M-Quick SIN). It was analyzed for MMSE scores of presbycusis with different age, hearing loss and SNR (signal-to-noise ratio, SNR) loss.Results ①The MMSE score of 60~69 years old group 27.89±1.82 was higher than that of 70~79 years old group 26.35±2.03 and ≥ 80 years old 25.19±2.07 (P<0.05); there was no significant difference in MMSE scores between 70~79 years old group and ≥ 80 years old group (P>0.05). ②There was no significant difference in MMSE score among different hearing loss groups (P>0.05). ③The MMSE score of mild SNR loss group 27.13±1.80 was higher than that of severe SNR Loss group 24.20±1.64 (P<0.05); there was no significant difference in MMSE score between mild SNR loss group and moderate SNR loss group, moderate SNR loss group and severe SNR loss group (P>0.05).Conclusion The main feature of cognitive impairment in patients with presbycusis is SNR loss. It is the best time to intervene in the early stage of hearing loss.
