Clinical Characteristics of Developmentally Delayed Children based on Interdisciplinary Evaluation

Area of Science:

• Pediatric Neurology
• Developmental Pediatrics
• Clinical Psychology

Background:

• Neurodevelopmental disorders (NDDs) present complex diagnostic challenges in children.
• Early identification and accurate diagnosis are vital for effective intervention and improved outcomes.
• Understanding clinical characteristics aids in distinguishing between various NDDs.

Purpose of the Study:

• To investigate the clinical features of children with suspected neurodevelopmental disorders.
• To identify diagnostic clues for clinical assessment of NDDs.
• To analyze risk factors associated with specific NDDs.

Main Methods:

• Retrospective review of medical records from an interdisciplinary clinic for developmental problems.
• Inclusion of 1,877 children evaluated between May 2001 and December 2014.
• Classification into major diagnostic groups: global developmental delay (GDD), autism spectrum disorder (ASD), developmental language disorder (DLD), and motor delay (MD).

Main Results:

• Global developmental delay (GDD) was the most common diagnosis (43.9%).
• Boys were significantly more prevalent than girls across all diagnostic groups.
• Specific risk factors were associated with different diagnoses: GDD probability increased with later walking age and neonatal history; ASD probability increased with male gender and decreased with maternal history.

Conclusions:

• The study highlights distinct clinical features aiding in the diagnosis of various neurodevelopmental disorders.
• Findings can assist clinicians in more effectively identifying children with potential NDDs during assessment.
• Understanding these characteristics supports earlier and more accurate diagnostic flagging.
