Sleep disorders in children with blindness
Insights
Blind children experience more sleep problems, including shorter sleep duration and increased daytime sleepiness, compared to sighted children. These sleep disturbances significantly impact their alertness and overall well-being.
Area of Science:
- Ophthalmology
- Sleep Medicine
- Pediatrics
Background:
- Sleep disorders are common in children, but less is known about their prevalence in blind children.
- Visual impairment can affect circadian rhythms and sleep patterns.
Purpose of the Study:
- To compare the frequency and types of sleep disorders in blind children versus age-matched controls.
- To investigate the impact of blindness on sleep and alertness in children.
Main Methods:
- A 42-item questionnaire was administered to 156 children (77 blind) aged 3-18 years.
- Data collected included sleep duration, sleep complaints, and daytime sleepiness.
- Results were compared between the blind children group and the control group.
Main Results:
- 17.4% of blind children slept <7 hours on weekdays vs. 2.6% of controls; blind children woke earlier.
- Blind children reported more sleep complaints and significantly higher rates of daily involuntary sleepiness (13.4% vs. 1.3%).
Conclusions:
- Blindness is associated with significant sleep disturbances in children.
- These sleep issues, including reduced sleep duration and increased sleepiness, exacerbate the challenges faced by blind children.
Abstract:
To evaluate the frequency and type of sleep disorders seen in blind children compared with matched controls, a 42-item questionnaire was used on 156 children (77 blind children) ranging from 3 to 18 years of age. A total of 17.4% of blind children reported sleeping less than 7 hours per night on weekdays compared with 2.6% of controls, with blind children awakening much earlier. Blind children had more sleep complaints, and 13.4% of blind subjects had daily episodes of involuntary sleepiness compared with 1.3% of controls. Blindness has an impact on sleep and alertness that adds to the primary disability.
