Insights
Sleep disturbance significantly impacts children with persistent post-concussion symptoms (PPCS), worsening mental health and tripling recovery time. Addressing sleep issues is crucial for better concussion outcomes in adolescents.
Area of Science:
- Pediatric neurology
- Sleep medicine
- Clinical psychology
Background:
- Persistent post-concussion symptoms (PPCS) affect a significant portion of children and adolescents.
- Sleep disturbances are common in pediatric concussion patients.
Purpose of the Study:
- To characterize sleep patterns in children and adolescents experiencing PPCS.
- To investigate the impact of sleep disturbance on clinical concussion outcomes, including symptom burden, cognition, and recovery time.
Main Methods:
- A prospective longitudinal study involving 20 participants (aged 11-18) with PPCS.
- Utilized wrist actigraphy for objective sleep assessment and the Insomnia Severity Index (ISI) to identify post-concussion clinical insomnia (PCCI).
- Conducted comprehensive concussion assessments at baseline and 4-week follow-up.
Main Results:
- 45% of participants with PPCS also presented with PCCI.
- Objective sleep parameters included total sleep time (452.1 ± 53.8 min), sleep latency (32.2 ± 16.3 min), wake after sleep onset (76.9 ± 21.4 min), and sleep efficiency (85.9 ± 3.7%).
- Mood disturbance predicted sleep disturbance; PCCI tripled recovery time compared to those without PCCI.
Conclusions:
- Sleep disturbance is strongly linked to poorer mental health in pediatric concussion patients.
- Clinical insomnia and sleep disturbances significantly prolong recovery duration in children and adolescents with PPCS.
- Targeting sleep issues may be a critical component in managing pediatric concussion recovery.
Background:
Persistent post-concussion symptoms (PPCS) affect 35% of children and adolescents with concussion. This study aimed to characterise sleep patterns in children and adolescents with PPCS and explore the effect of sleep disturbance on clinical concussion outcomes.
Methods:
A prospective longitudinal study was conducted in participants with PPCS (n = 20, aged 11-18 years) presenting to a tertiary referral clinic. Participants completed a battery of concussion assessments at their initial consultation and at 4 weeks follow-up to assess and monitor symptom burden, cognition, balance, mental health, and exercise tolerance. The Insomnia Severity Index (ISI) was used to identify participants with post-concussion clinical insomnia (PCCI). Wrist actigraphy was used to objectively characterise sleep patterns, including total sleep time, sleep latency, wake after sleep onset and sleep efficiency, over a 14-day period. Participants were followed until they were recovered from concussion.
Results:
Forty-five percent of participants with PPCS also had PCCI. Objective mean ± SD sleep parameters of participants were: total sleep time 452.1 ± 53.8 min, sleep latency 32.2 ± 16.3 min, wake after sleep onset 76.9 ± 21.4 min, and sleep efficiency 85.9 ± 3.7%. Mood disturbance was a significant predictor of sleep disturbance at the 4-week follow-up (P = 0.01). Recovery time was three times greater for participants with PCCI than those with no PCCI (median (interquartile range): 150 (91-247) vs 47 (30-58) days, P = 0.04).
Conclusions:
Sleep disturbance is significantly associated with poorer mental health and prolonged recovery time in children and adolescents with PPCS.
