Cerebral palsy in children: early diagnosis and rehabilitation

Early, accurate diagnosis is possible before 6 months; high-risk babies are followed on a schedule; early rehabilitation changes the outcome.

Cerebral palsy (CP) is a lasting disorder of movement and posture caused by damage to the developing brain. The injury does not progress, but its effect on movement changes as the child grows. According to a meta-analysis of population studies, CP occurs in about 2 of every 1,000 live births; among babies born before 28 weeks the risk is many times higher (about 112 per 1,000). The key message of the modern approach: diagnosis can be made before 6 months, even earlier, and early intervention begins during the most plastic period of the brain.

Risk factors

Premature birth (especially before 32 weeks), low birth weight, lack of oxygen at birth (hypoxic-ischemic encephalopathy), severe infection or seizures in the newborn period, brain hemorrhage, multiple pregnancy, severe jaundice. Babies in a high-risk group are followed by a neurologist even if there are no complaints.

Early signs

  • Muscles that are very stiff or very floppy; a baby who “stiffens” or “slips through” when you pick them up
  • Not holding the head up at 4 months, not rolling over at 6 months, not sitting at 9 months
  • One side of the body used less; one hand constantly in a fist (clenched fists on both sides are normal in the first months)
  • Primitive reflexes that persist after 6 months
  • A change in the quality of spontaneous movements (see below)
  • Feeding difficulty, extreme irritability or sluggishness

How early diagnosis is made

According to the current international approach (JAMA Pediatrics, 2017), three tools are used together for early, accurate diagnosis:

  1. General Movements Assessment (Prechtl GMA): observing the baby's spontaneous movements on video. The absence of “fidgety” movements at 3–5 months has high predictive value for later CP — in a systematic review, sensitivity was 97% and specificity 89%.
  2. Hammersmith Infant Neurological Examination (HINE): a standard scored exam for ages 2–24 months; it plays an important role in diagnosis and prognosis, and the scores help predict the type and severity of CP.
  3. Brain MRI: shows the location and nature of the injury.

For premature babies, among the assessments performed up to 4 months, the Prechtl general movements method has the best predictive value. If the diagnosis cannot be made with certainty, intervention begins with a note of “high risk of CP” — not waiting.

Types

Spastic (the most common; one side — hemiplegia, the legs — diplegia, the whole body — quadriplegia), dyskinetic (involuntary movements), ataxic (balance and coordination) and mixed. Motor function is classified on the international GMFCS scale from level I to V; this makes the plan and expectations concrete.

Treatment and rehabilitation

Rehabilitation starts early and favors goal-directed activities built around the child's daily life: physical therapy, occupational therapy and, when needed, speech-language therapy. For spasticity: medication and, when indicated, botulinum toxin injections; orthoses; orthopedic monitoring (watching the hip joint). Related conditions — epilepsy, feeding and swallowing difficulties, constipation, vision and hearing, pain, sleep — are part of the overall plan and affect quality of life as much as movement does.

Frequently asked questions

Can CP be identified before age 1?

Yes. In a high-risk baby, diagnosis with GMA, HINE and MRI can be made with high accuracy by 5–6 months. Earlier support means a better outcome.

Is CP a progressive condition?

The brain injury does not progress. However, muscle and joint changes can develop with growth, which is why regular monitoring and rehabilitation are needed.

Will my child walk?

It depends on the type and the GMFCS level. Most children with mild or moderate forms walk independently or with an assistive device. Realistic goals for each child are set together with the family.

Is every “increase in muscle tone” CP?

No. Temporary changes in muscle tone are common in babies and may normalize before age 1. Diagnosis rests on observation over time and standard tools, not on a single exam.
