Treatment of Night Terrors (Sleep Terrors)
Reassurance and watchful waiting is the primary approach for night terrors in children, as they are benign and self-limited in the vast majority of cases, with most children outgrowing them by late adolescence without any intervention. 1
Critical Distinction: Night Terrors vs. Nightmares
Before proceeding, it's essential to clarify that night terrors (sleep terrors) are fundamentally different from nightmares, and the treatment approaches differ significantly:
- Night terrors occur during NREM stage 3-4 sleep (deep sleep), typically in the first third of the night, with no dream recall, autonomic hyperactivity, and amnesia for the event 1, 2
- Nightmares occur during REM sleep, are remembered, and have specific evidence-based treatments outlined in AASM guidelines [3-3]
The provided guidelines [3-3] address nightmare disorder, not night terrors, so their recommendations (image rehearsal therapy, prazosin) are not applicable to true sleep terrors.
Management Algorithm for Night Terrors
First-Line: Non-Pharmacological Management
1. Parental Education and Reassurance
- Explain the benign, self-limited nature (occurs in 1-6.5% of children ages 1-12, peaks at 5-7 years) 1
- Emphasize that 83.9% resolve spontaneously without intervention 1
- Inform parents NOT to attempt awakening or consoling during episodes, as this is ineffective and may prolong the event 1
2. Optimize Sleep Hygiene
- Ensure adequate sleep duration, as sleep deprivation is a major precipitating factor 1
- Maintain consistent sleep-wake schedules
- Create appropriate sleeping environment
- Identify and eliminate triggers (fever, stress, sleep fragmentation) 2
3. Scheduled Awakening (For Frequent Episodes)
- Wake the child approximately 30 minutes before the typical time of sleep terror occurrence 1
- This technique is often effective for frequently recurring episodes
- Continue for several weeks until pattern breaks
Second-Line: Pharmacological Intervention
Medications should be reserved for severe, frequent episodes causing functional impairment (fatigue, daytime sleepiness, distress, safety concerns).
Medication Options (in order of evidence strength):
Clonazepam (short-term use at bedtime)
L-5-Hydroxytryptophan (L-5-HTP)
Midazolam (15 mg oral)
- Eliminated night terrors in all but one patient in a controlled study 5
- Well-tolerated with no side effects
- Modified sleep architecture favorably
- Consider for refractory cases
Other agents with limited evidence:
Common Pitfalls to Avoid
- Do not confuse night terrors with nightmares – they require completely different management approaches
- Do not use image rehearsal therapy or prazosin – these are for nightmare disorder, not sleep terrors
- Avoid clonazepam and venlafaxine for nightmare disorder [3-3], but clonazepam may be appropriate for true sleep terrors 1, 2
- Do not attempt to wake or console during episodes – this is ineffective and may worsen the event 1
- Do not overlook underlying conditions – treat fever, obstructive sleep apnea, or other sleep fragmenting conditions 1
When to Consider Medical Workup
- Episodes persisting beyond adolescence
- New onset in adults (consider neurological evaluation)
- Associated with injury risk requiring safety interventions
- Presence of EEG abnormalities or motor automatisms (may require video-polysomnography) 5, 8
