To evaluate four dimensions of fatigue, including subjective fatigue severity, concentration problems, reduced motivation, and activity in patients with single-sided deafness.

Following audiological assessment, the Checklist Individual Strength scale and Montreal Cognitive Assessment were performed on 41 adults with single-sided deafness and 41 sex-matched adults with normal bilateral hearing in the study group and control group, respectively. Subjective fatigue severity, concentration, motivation, activity level and cognitive performance were analysed between and within groups.

Individuals with single-sided deafness exhibited reduced concentration and motivation; however, their activity level was average. Subjective fatigue symptoms were more prevalent in individuals with single-sided deafness than in control participants. The concentration problem was related to decreased cognitive performance.

This study revealed negative somatic consequences of single-sided deafness. Self-perceived fatigue is likely underestimated in this population due to the limited studies reported in the literature. Further studies should focus on counselling, follow up and hearing rehabilitation concerning ameliorating fatigue.
