Concentration problems associated with fatigue severity in those with vision impairment

Key takeaways:
- More than 60% of participants had severe fatigue.
- Concentration problems were associated with fatigue severity.
Concentration problems and fatigue severity appeared to be positively associated in patients with visual impairment, according to research published in Optometry and Vision Science.
“To date, the association between concentration and fatigue in individuals with [visual impairment (VI)] remains largely unexplored,” Manon H. J. Veldman, MD, a researcher at Amsterdam UMC, and colleagues wrote. “This study aimed to expand upon previous research by conducting a quantitative investigation into the association between concentration problems and the severity of fatigue in adults with VI.”
In a cross-sectional study of 213 adults with VI (mean age, 57.2 years; 61% women), the researchers measured concentration using the Checklist of Individual Strengths subscale Concentration and fatigue using the Checklist of Individual Strengths subscale Fatigue Severity. The researchers also considered potential confounding variables including sociodemographic and vision-related characteristics.
More than 60% of participants experienced severe fatigue, with concentration problems both directly and positively associated with fatigue severity.
Severity of VI, duration of VI and work status were not significantly associated with either concentration problems or fatigue severity. However, the researchers noted that certain comorbidities, negative cognitions, sleep and depression were not included in the study and may influence concentration and fatigue.
“As fatigue has a major impact on people’s daily life and participation in society, research on cognitive overload is necessary to stimulate awareness and treatment of these symptoms in clinical practice,” Veldman and colleagues wrote.
