Neurological Follow-Up for Premature Babies

A baby born before the 37th week of pregnancy is considered premature (preterm). Because the fastest period of brain development falls in the last weeks of pregnancy, the nervous system of these babies needs special attention. Most grow up healthy, but the risk is higher than in the general population: cerebral palsy occurs in about 112 per 1,000 babies born before 28 weeks and about 59 per 1,000 of those born weighing 1,000–1,499 g (compared with 2 per 1,000 in the general population). That is exactly what early, scheduled follow-up is for: to spot a problem in time and not delay support.

Corrected age

Development is assessed by corrected age, not calendar age: subtract the number of weeks your baby was born before week 40. A 6-month-old born at 32 weeks has a corrected age of 4 months and is expected to have the skills of a 4-month-old. This adjustment is usually applied until age 2.

Neurological risks

Brain hemorrhage (intraventricular hemorrhage) and injury to the white matter (periventricular leukomalacia)
Cerebral palsy, motor delay, coordination problems
Vision (retinopathy of prematurity) and hearing disorders — both are checked on a schedule
Speech and cognitive delay, learning and attention difficulties at school age
Feeding and swallowing difficulties, reflux

The risk rises as gestational age at birth decreases and as time spent in intensive care grows longer. Severe infection in the newborn period, long ventilation and some medications also affect the outcome — these are reviewed in the epicrisis.

Follow-up schedule

Corrected age	What is assessed
First visit (2–4 weeks after discharge)	Muscle tone, reflexes, head circumference, fontanelle, feeding, sleep; review of the epicrisis
3–4 months	General Movements Assessment (fidgety period), HINE, head control, hand function
6 months	Rolling over, early sitting, reaching for objects, sounds, social smile
9 months	Sitting, passing objects from hand to hand, turning to name, babbling
12 months	Standing, first words, pointing, fine movements
18 and 24 months	Walking, speech, play; autism screening at 18–24 months; corrected age applied until 24 months
Ages 3–6	Speech, attention, behavior, school readiness

According to systematic reviews, among assessments done in the first 4 months, the general movements method (Prechtl GMA) best predicts later motor outcome; at 8–12 months, standard motor scales are more informative. When indicated, a brain ultrasound (until the fontanelle closes) or an MRI is ordered.

What parents can do at home

Tummy time (when awake, under supervision), talking and reading to your baby, face-to-face interaction, placing your baby on their back to sleep, keeping to the vaccination schedule (for premature babies the schedule follows chronological age), and watching feeding. Record any movement or episode that worries you on video and show it at the exam.

Frequently asked questions

My baby is normal for corrected age but behind peers

This is expected, and the gap usually closes by age 2. If there is a delay even by corrected age, the assessment is taken further.

Which babies should a neurologist follow, by gestational age?

Every baby born before 34 weeks, weighing under 1,500 g, or who spent time in intensive care should be followed on a schedule. For babies born at 34–37 weeks, at least one neurological exam is advised, followed by monitoring if concerns arise.

When can the risk of cerebral palsy be assessed?

At 3–4 months (corrected), the risk can be assessed with high accuracy using GMA and HINE and, when needed, MRI; support begins before the diagnosis is confirmed. Cerebral palsy in children
