A developmental disorder is a long-term condition that affects how a child grows, learns, communicates, or behaves. These challenges usually appear early in childhood, often before age and influence areas such as speech, motor skills, attention, emotional regulation, and social interaction.
Unlike temporary delays, developmental disorders continue throughout childhood, although early support and therapy can significantly improve daily functioning and long-term outcomes.
In simple terms:
A developmental disorder is a condition that interferes with typical developmental milestones during childhood.
These conditions are often referred to as neurodevelopmental disorders, because they impact how the brain develops.
Common Examples of Developmental Disorders
- Autism Spectrum Disorder (ASD)
- ADHD
- Developmental Language Disorder (DLD)
- Learning Disabilities
- Developmental Coordination Disorder (Dyspraxia)
