What are the risk factors for ADHD in preterm infants?

ByMy Patient Advice

The ADHD risk preterm infants face is notably higher than that of full-term babies. Premature birth can interfere with vital stages of brain development, particularly those that shape attention, impulse control, and emotional regulation. 

The likelihood of ADHD increases the earlier a baby is born, especially among preemies delivered 32 weeks before. This is due to a combination of biological immaturity and external challenges, such as extended stays at hospital or medical interventions. Understanding the ADHD risk preterm infants experience helps families and clinicians focus on risk factors that may influence behaviour and cognitive development as the child grows. 

Multiple studies now show that ADHD likelihood is elevated in children born prematurely, often due to overlapping influences rather than a single cause.

Key Risk Factors to Monitor in Preterm Infants 

Being aware of certain patterns and experiences early on can help support early intervention. Below are common risk factors linked to ADHD in preemies:

Low birth weight and gestational age

The more premature the infant, the greater the risk. Extremely low birth weight babies are particularly vulnerable to developmental delays. 

Medical complications

Conditions like brain bleeds, respiratory problems, or infections shortly after birth can disrupt brain function. 

Stressful early environments

Lengthy hospital stays, limited physical contact, or sensory overstimulation can influence emotional development and increase ADHD likelihood. 

Understanding and tracking these influences can lead to more informed care decisions.
