Global Developmental Delay refers to a child's delayed progress in reaching developmental milestones compared to other children their age. It is not a specific diagnosis, but rather a description of a pattern of delays across multiple areas of development such as cognitive, motor, social, and emotional skills. The cause of Global Developmental Delay can vary widely and may include genetic or metabolic disorders, brain injuries, exposure to certain medications or environmental factors, or other underlying conditions that affect a child's overall growth and development. Early intervention and support services such as physical therapy, occupational therapy, speech therapy, and special education can help children with Global Developmental Delay reach their full potential.
