Nonmotor Symptoms in Pediatric Movement Disorders: A Comprehensive Review

Strategic Insights -

Researchers from Rothschild Foundation Hospital, Paris, France, have conducted a comprehensive review of nonmotor symptoms (NMSs) in pediatric movement disorders, highlighting significant gaps in the evaluation of these symptoms. The study, published in the journal Neurology, emphasizes the importance of considering NMSs, such as tics, dystonia, and cerebral palsy, in children with movement disorders. The review of 382 studies from 1990 to 2023 found that while most articles focused on cognitive impairment, mental health, and behavioral difficulties, other critical aspects like sleep disturbance, fatigue, and gastrointestinal issues were often overlooked.

Key Takeaways:

  • The majority of studies (64.3%) focused on cognitive impairment, mental health, and behavioral difficulties in children with movement disorders.
  • Self-esteem and communication-critical components of social functioning-were rarely evaluated (only 6.5% of studies).
  • The assessment of sleep disturbance, fatigue, and gastrointestinal and urinary symptoms was less frequently addressed (11.5% of studies).
  • Significant gaps exist in the evaluation of NMSs in pediatric movement disorders, particularly in areas such as pain, sleep, and gastrointestinal issues.
  • Standardization of NMS assessment is needed, but it is unclear whether disorder-specific tools are preferable to broader NMS-focused measures.
  • Using general scales may be a pragmatic first step, with refinement into disorder-specific tools as our understanding of symptom patterns evolves.
  • Cross-cultural validation is essential to improve the applicability of NMS scales across diverse populations.

Statistics:

  • 382 studies were included in the review, covering a 33-year period (1990-2023).
  • 64.3% of studies focused on cognitive impairment, mental health, and behavioral difficulties in children with movement disorders.
  • 6.5% of studies evaluated self-esteem and communication-critical components of social functioning.
  • 11.5% of studies assessed sleep disturbance, fatigue, and gastrointestinal and urinary symptoms.
  • The majority of studies were cross-sectional (52.3%), cohort (23.6%), or case-control (14.6%).
