Living with Acute bilirubin encephalopathy

A brain condition in newborns caused by too much bilirubin building up, leading to sleepiness, poor feeding, and other signs.

Understanding Acute bilirubin encephalopathy

Acute bilirubin encephalopathy is a rare brain condition in newborns caused by bilirubin building up in certain parts of the brain.

It results from severe newborn jaundice (a high level of bilirubin in the blood). Symptoms usually start within the first three to five days of life. Other features can include fever, pauses in breathing (apnea), seizures, and coma.

Signs & symptoms

Symptoms vary from baby to baby. GARD lists these among the most common:

  • Trouble feeding
  • Seizures
  • Stiff muscles (hypertonia)
  • Cerebral palsy
  • Hearing loss (sensorineural hearing impairment)
  • Long-lasting yellowing of the skin in a newborn

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
