Study objectives: There is a well-established association between headache disorders and sleep disturbances in children, but it is unknown if sleep disturbance plays a role in pediatric intracranial hypertension. The objective of this study was to examine sleep issues related to pediatric intracranial hypertension.
Methods: Patients with intracranial hypertension who were followed in the Pediatric Intracranial Hypertension Clinic were recruited between July 2017 and September 2018. Demographic data was collected from the electronic medical record in addition to patient and parent completed questionnaires. Information on sleep behaviors was gathered using the Children's Sleep Habits Questionnaire, and control data was obtained from patient siblings. Statistical analyses were performed using paired t-tests or two-sample t-tests, as appropriate.
Results: Sixty-two pairs of patients and matched sibling controls were compared. There was a statistically significant difference in total sleep disturbance score (control mean 44.3; patient mean 48.1; n=33 pairs, t=-2.2, p=0.035) as well as subscale scores of sleep onset delay (control mean 1.4; patient mean 1.7; n=52 pairs, t=-2.53, p=0.014), parasomnias (control mean 8.5; patient mean 9.5; n=42 pairs, t=-2.59, p=0.013), and sleep disordered breathing (control mean 3.1; patient mean 3.4; n=44 pairs, t=-2.61, p=0.013). There was no difference found in bedtime resistance, sleep duration, sleep anxiety, night wakings, and daytime sleepiness subscales. Furthermore, there was no difference in total sleep disturbance score between patient subsets including: primary versus secondary intracranial hypertension, body mass index, pubertal status, presence of headaches, or intracranial hypertension treatment.
Conclusions: This observational study suggests that pediatric intracranial hypertension is associated with a modest increase in sleep disturbances.
