Living with Bilirubin encephalopathy

A rare brain condition that can happen when a newborn's untreated jaundice lets bilirubin build up and harm the brain.

Understanding Bilirubin encephalopathy

Bilirubin encephalopathy is a rare brain condition that can happen when a newborn has untreated jaundice and bilirubin builds up to harmful levels.

Mild jaundice is common in newborns. In some babies, bilirubin gets too high and can harm certain parts of the brain. Babies may have breathing problems, muscle spasms, or low muscle tone. Later, there may be movement delays, seizures, hearing loss, intellectual disability, and speech problems. Together these are called bilirubin-induced neurologic dysfunction (BIND).

Signs & symptoms

Symptoms vary from person to person. GARD describes these as possible signs:

  • Breathing problems in newborns
  • Muscle spasms or low muscle tone
  • Delays in movement
  • Seizures
  • Hearing loss
  • Speech problems and intellectual disability

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.

Quick facts

Symptoms usually startNewborn and as an Infant

Bilirubin, a yellow substance in the blood, builds up to harmful levels. Risk is higher in babies born early or with feeding problems, bruising, a sibling who had jaundice, or a mother with blood type O or Rh-negative blood.
