Abstract:

Objective To study the influence of age-related functional hearing loss on memory ability.
Methods From January to October, 2018, 30 patients aged 52 to 76 years visiting otolaryngology were screened hearing using a computer aided platform, and then were divided into two groups according to the results. Those with good speech recognition in noise (SIN < -2.63 dB) were in L group ( n = 15) and those with poor speech recognition in noise (SIN > -2.63 db) were in H group ( n = 15). They were assessed with Paired Associates Learning (PAL) and Spatial Working Memory (SWM) of Cambridge Neuropsychological Test Automated Battery in loading of four, six and eight models.
Results The amount of errors of both PAL and SWM increased with the loading in both groups (χ2> 28.182,P < 0.001). The amount of errors of PAL was less in L group than in H group under any loading ( U < 53.5, P < 0.05), while the amount of errors of SWM only less under loading of six models ( U = 55.0, P < 0.05). There was no significant interaction between hearing and loading ( F < 1.680, P > 0.05).
Conclusion Age-related functional hearing loss tend to impair episodic memory rather than working memory, whatever the impacts of memory load.

Key words: functional hearing loss, age, working memory, episodic memory, memory load
