Sleep disturbances, including insomnia and circadian rhythm issues, are common in Cornelia de Lange Syndrome (CdLS). This study screened 31 CdLS patients, finding significant sleep problems in both children and adults.
Area of Science:
- Genetics and Rare Diseases
- Sleep Medicine
- Pediatric Neurology
Background:
- Cornelia de Lange Syndrome (CdLS) is a rare genetic disorder associated with significant health challenges.
- Sleep disturbances affect up to 55% of individuals with CdLS.
- Previous research suggests a link between sleep issues and intellectual disability or self-injurious behavior in non-CdLS populations.
Purpose of the Study:
- To investigate the prevalence and characteristics of sleep disturbances in individuals with CdLS.
- To screen for symptoms indicative of insomnia and circadian rhythm disorders in a cohort of CdLS patients.
- To explore potential differences in sleep patterns between pediatric and adult CdLS populations.
Main Methods:
- A sleep history questionnaire was administered to caregivers of 31 patients (19 children, 12 adults) with CdLS.
- The questionnaire focused on sleep patterns and evening sleep behaviors.
- Data was collected to screen for signs and symptoms of insomnia and circadian rhythm disorders.
Main Results:
- Major difficulties in falling asleep (75% pediatric, 33% adult) and staying asleep (52% pediatric, 33% adult) were reported.
- Average time to sleep onset was 27 minutes, increasing to 37.8 minutes for those with stated difficulty.
- Pediatric patients experienced more nighttime awakenings (1.5) compared to adults (0.7), and took longer to fall back asleep (61.8 min vs. 14.9 min).
Conclusions:
- Symptoms suggestive of insomnia or circadian rhythm disorders are prevalent in individuals with CdLS.
- Adults with CdLS may experience less severe sleep disturbances than children, though further research is needed.
- Characterizing sleep disturbances in CdLS is crucial for improving patient care and quality of life.
