Failure to reach developmental milestones by the expected age range is known as global developmental delay (GDD). According to objective standards, this describes a noticeable delay in two or more developmental domains in children five years old or relatively young. Cognition, speech and language, personal-social, and daily living activities are the developmental domains getting affected.
The studies indicate that children with GDD have significantly limited intellectual functioning (problem-solving, learning, reasoning, and learning) and adaptive behaviour (practical, social, and conceptual skills) that begin before age 18. Learning disability, as opposed to intellectual disability, is defined by the UK Department of Health’s strategy as the presence of impaired social functioning accompanied by impaired intelligence that began before adulthood and had a long-term impact on development.
What Causes Global Developmental Delay In Kids?
According to some studies, family history, which may include chromosomal disorders like Fragile X Syndrome (FXS) or genetic conditions like Down syndrome, may be a factor in overall developmental delay. Additionally, it might arise due to various environmental factors like pregnancy complications or exposure to toxins.
The researchers discovered the use of DNA testing to identify potential causes of GDD in a recent clinical paper published in late 2019. They found GDD in 55.7% of patients, which is a sizable number. GDD may also come up by life events, illnesses such as brain injuries or infections, and malnutrition.
