Insights
This report establishes practice parameters for using polysomnography (PSG) and multiple sleep latency tests (MSLT) in children with non-respiratory sleep disorders. These guidelines aid in diagnosing conditions like narcolepsy and periodic limb movement disorder.
Area of Science:
- Pediatric Sleep Medicine
- Neurology
- Clinical Practice Guidelines
Background:
- No current evidence-based practice parameters exist for pediatric non-respiratory sleep disorders.
- Polysomnography (PSG) and Multiple Sleep Latency Tests (MSLT) are utilized in this age group.
- Guidelines are crucial for consistent and effective diagnosis.
Purpose of the Study:
- To present evidence-based practice parameters for PSG and MSLT in children.
- To provide guidance on the indications for these diagnostic tools.
- To address the assessment of non-respiratory sleep disorders in pediatric patients.
Main Methods:
- A task force of experts was convened by the American Academy of Sleep Medicine (AASM).
- Literature review and evidence grading were performed using the American Academy of Neurology system.
- Practice parameters were developed and approved by the AASM Board of Directors.
Main Results:
- PSG is indicated for suspected periodic limb movement disorder (PLMD) and restless legs syndrome (RLS).
- MSLT (following PSG) is indicated for suspected narcolepsy and other hypersomnias.
- PSG is recommended for children with parasomnias, epilepsy, or enuresis if sleep-disordered breathing or PLMD is suspected.
- PSG is not routinely indicated for sleep-related bruxism.
Conclusions:
- Nocturnal PSG and MSLT are valuable tools for pediatric non-respiratory sleep disorders.
- Integration with clinical evaluation is essential for accurate diagnosis.
- These parameters will standardize the use of PSG and MSLT in children.
Background:
Although a level 1 nocturnal polysomnogram (PSG) is often used to evaluate children with non-respiratory sleep disorders, there are no published evidence-based practice parameters focused on the pediatric age group. In this report, we present practice parameters for the indications of polysomnography and the multiple sleep latency test (MSLT) in the assessment of non-respiratory sleep disorders in children. These practice parameters were reviewed and approved by the Board of Directors of the American Academy of Sleep Medicine (AASM).
Methods:
A task force of content experts was appointed by the AASM to review the literature and grade the evidence according to the American Academy of Neurology grading system.
Recommendations For Psg And Mslt Use:
PSG is indicated for children suspected of having periodic limb movement disorder (PLMD) for diagnosing PLMD. (STANDARD)The MSLT, preceded by nocturnal PSG, is indicated in children as part of the evaluation for suspected narcolepsy. (STANDARD)Children with frequent NREM parasomnias, epilepsy, or nocturnal enuresis should be clinically screened for the presence of comorbid sleep disorders and polysomnography should be performed if there is a suspicion for sleep-disordered breathing or periodic limb movement disorder. (GUIDELINE)The MSLT, preceded by nocturnal PSG, is indicated in children suspected of having hypersomnia from causes other than narcolepsy to assess excessive sleepiness and to aid in differentiation from narcolepsy. (OPTION)The polysomnogram using an expanded EEG montage is indicated in children to confirm the diagnosis of an atypical or potentially injurious parasomnia or differentiate a parasomnia from sleep-related epilepsy (OPTION)Polysomnography is indicated in children suspected of having restless legs syndrome (RLS) who require supportive data for diagnosing RLS. (OPTION) RECOMMENDATIONS AGAINST PSG USE: Polysomnography is not routinely indicated for evaluation of children with sleep-related bruxism. (STANDARD) CONCLUSIONS: The nocturnal polysomnogram and MSLT are useful clinical tools for evaluating pediatric non-respiratory sleep disorders when integrated with the clinical evaluation.
