At what age can ADHD be diagnosed in preterm infants? 

ADHD diagnosis age in preterm infants is an important question for parents and healthcare professionals, as early identification can lead to timely interventions. ADHD symptoms can appear early in life, but the right diagnosis timing for preterm infants can be more challenging as compared to full-term children. 

Although ADHD is typically diagnosed in school-aged children, signs can begin to emerge in infancy, especially in preterm infants who may experience developmental delays. These infants may show early ADHD signs, such as hyperactivity, difficulty focusing, or trouble regulating emotions, but formal diagnosis often requires time and careful observation. 

When ADHD Symptoms Appear in Preterm Infants 

While formal ADHD diagnosis age in preterm babies may take time, early signs can appear well before school age. Here’s what to watch for: 

Early onset of symptoms

In preterm infants, signs of ADHD can become noticeable by 6-12 months, particularly in areas like attention span and activity levels. These symptoms may include excessive fidgeting, trouble staying calm, or unusual difficulty focusing. 

Delayed diagnosis

Although ADHD diagnosis age preterm infants typically happens later, by the time children reach preschool or early school years, healthcare providers may be able to assess whether the early signs they exhibited have evolved into a more recognisable pattern of ADHD. 

Importance of early monitoring

Recognising and tracking these early signs in preterm infants can help guide professionals towards a diagnosis and intervention plan as early as possible. 

Early diagnosis and intervention are crucial to ensuring children get the right support as soon as possible.
