ABSTRACT
INTRODUCTION:
As the human lifespan rises, older people are increasingly affected by multimorbidity, including hearing impairment (HI), frailty, and cognitive decline.OBJECTIVE:
We studied the effect of HI on the cognitive performance of older patients with mild cognitive impairment and mild dementia and how this effect is altered when HI and frailty coexist.METHODS:
The sample comprised 172 outpatients (age ≥65 years) with a Clinical Dementia Rating of 0.5-1 and a Mini-Mental State Examination score ≥20. Cognitive, neuropsychological, physical function tests, and body measurements were performed. The participants' comorbidity indices were calculated, and they were asked to report their hearing condition. Finally, the participants were divided into 4 groups based on the presence of frailty, HI, both conditions, or neither.RESULTS:
The presence of HI was significantly associated with a lower Digit Symbol Substitution Test (DSST) score (unadjusted model p = 0.003; adjusted p = 0.012). Moreover, people with both HI and frailty were more likely to have a low DSST score than those in the other groups (unadjusted model OR 3.741, 95% CI 1.374-10.183, p = 0.010; adjusted model OR 4.192, 95% CI 1.026-17.136, p = 0.046).CONCLUSIONS:
This study highlights the negative relationship between cognitive performance scored on the DSST and the presence of HI. Furthermore, the presence of both frailty and HI is associated with a worse cognitive score than HI alone.Palavras-chave
