Insights
Motor delay in children under two often indicates Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations (ESSENCE). Early assessment is crucial for timely diagnosis and intervention.
Area of Science:
- Pediatric Neurology
- Developmental Pediatrics
- Neurodevelopmental Disorders
Background:
- Early motor development abnormalities are noted in various neurodevelopmental conditions.
- Limited research exists on clinically representative cohorts presenting with motor delay before age two.
- Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations (ESSENCE) encompass a range of developmental disorders.
Purpose of the Study:
- To investigate if early motor delay is an indicator of ESSENCE in young children.
- To assess the diagnostic yield of motor delay in identifying neurodevelopmental disorders.
- To determine the prevalence of ESSENCE in children evaluated for motor delays.
Main Methods:
- A prospective clinical cohort study was conducted.
- The study included a one-year cohort of children under two years old presenting with delayed or abnormal gross motor development.
- Children were followed up to assess for ESSENCE diagnoses.
Main Results:
- 93% of the 30 children studied received diagnoses within the ESSENCE umbrella.
- Among children with identified or suspected etiology, 87% had ESSENCE disorders.
- All children without a known etiology were found to have ESSENCE disorders or symptoms.
Conclusions:
- The majority of young children with motor delay meet criteria for ESSENCE disorders.
- Motor problems in early childhood warrant comprehensive clinical assessment beyond motor function.
- Systematic follow-up is essential for children presenting with early motor delays.
Background:
Abnormalities of early motor development have been reported in autism spectrum disorder, attention-deficit/hyperactivity disorder, intellectual developmental disorder, developmental coordination disorder, and other Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations (ESSENCE). However, few studies have been conducted with a view to following up a clinically representative cohort of children coming for assessment of motor delay before age two years. We performed a prospective clinical cohort study to examine whether or not early motor delay is often an indication of ESSENCE.
Methods:
The sample comprised a one-year cohort of all children who came to a Japanese neurodevelopmental center before their second birthday because of delayed or abnormal gross motor development. The children were followed up from the ESSENCE viewpoint.
Results:
Of the 30 children, 28 (18 boys and 10 girls) (93%) were given diagnoses subsumed under the ESSENCE umbrella. Of the 15 children with an identified or strongly suspected etiology, 13 (8 boys and 5 girls) (87%) had ESSENCE disorders or symptoms. Of the 15 children without a known etiology, all had ESSENCE disorders or symptoms.
Conclusion:
This study indicated that the vast majority of children with motor delay or abnormality in the first two years of life meet criteria for a disorder within the group of ESSENCE at follow-up; this means that young children, presenting with motor problems always need a broad clinical assessment, not just related to motor function, and systematic follow-up.
