What is the treatment for Non-Rapid Eye Movement (NREM) parasomnia?

Treatment of NREM Parasomnia

The treatment of NREM parasomnia should begin with safety measures and behavioral interventions, followed by pharmacotherapy with clonazepam (0.5-1mg at bedtime) for persistent cases with risk of injury. 1

Understanding NREM Parasomnias

• NREM parasomnias are undesirable non-deliberate physical or emotional events that occur during sleep, most commonly during entry into sleep or during arousals 1
• Common manifestations include sleepwalking, night terrors, confusional arousals, and sleep-related eating disorder 1
• NREM parasomnias are more common in children, while REM sleep behavior disorder (RBD) is more prevalent in older adults 1

Treatment Approach

First-Line: Safety Measures and Behavioral Interventions

1. Environmental safety modifications:

   • Secure the bedroom environment to reduce injury risk 1
   • Remove potentially dangerous objects from the bedroom 1
   • Consider padding hard and sharp surfaces around the bed 1
   • Lower bed mattress or place mattress on floor if necessary 1

2. Behavioral and psychological interventions:

   • Implement proper sleep hygiene measures (consistent sleep schedule, relaxing bedtime routine) 2, 3
   • Address and manage priming factors:
     • Reduce stress through cognitive behavioral therapy or mindfulness-based stress reduction 2, 3
     • Treat any concurrent sleep disorders (e.g., sleep apnea) 2
     • Ensure adequate sleep duration and quality 3, 4
   • Consider specialized behavioral techniques:
     • Scheduled awakenings (waking the patient 15-30 minutes before typical episode time) 3
     • Hypnosis has shown efficacy in multiple case reports 3, 4
     • Relaxation techniques to reduce arousal and stress 3

Second-Line: Pharmacotherapy

When behavioral interventions are insufficient and episodes pose risk of injury:

1. Benzodiazepines:

   • Clonazepam (0.5-1mg at bedtime) is the most commonly prescribed medication 1, 2
   • Effective in approximately 90% of cases 1
   • May be taken 1-2 hours before bedtime if sleep onset insomnia or morning drowsiness occurs 1
   • Caution in older adults as it appears on the American Geriatrics Society Beers Criteria list of potentially inappropriate medications 1

2. Alternative medications:

   • Melatonin (3-15mg) has shown efficacy in some cases 2, 5
   • Antidepressants may be beneficial in certain patients 2
   • For sleep-related eating disorder specifically, topiramate, pramipexole, or sertraline may be effective 5

Special Considerations

• Medication review: Evaluate and discontinue medications that may exacerbate parasomnias, particularly sedative-hypnotics 5
• Underlying conditions: Identify and treat comorbid sleep disorders or neurological conditions that may trigger episodes 2, 5
• Monitoring: Regular follow-up to assess treatment efficacy and adjust interventions as needed 3

Treatment Efficacy

• In a large retrospective study of 512 patients with NREM parasomnia, 97.2% reported adequate symptom control with treatment 2
• Approximately 60% required pharmacotherapy, while 32% achieved control with non-pharmacological interventions alone 2
• Benzodiazepines were the most commonly prescribed effective medications (47.1%) 2

Pitfalls to Avoid

• Failing to address underlying sleep disorders that may trigger parasomnias 2
• Overlooking safety measures, which should be implemented regardless of pharmacotherapy 1
• Not considering the potential for medication-induced parasomnias, particularly with sedative-hypnotics 5
• Treating without proper diagnosis - polysomnography may be needed to differentiate from other sleep disorders 1
