Kernicterus Symptoms

Kernicterus is a form of brain damage that results when bilirubin enters the brain tissue. This occurs in newborns because the blood-brain barrier is not yet completely formed.

Jaundice

Slight jaundice is normal in newborns but severe jaundice can indicate that bilirubin is building to dangerous levels.

Extreme Lethargy

Babies normally spend a good deal of time sleeping but a lethargic baby will have difficulty waking up or staying awake. Lethargic babies may not respond to touching or have poor startle reflexes.

Crying

Babies with kernicterus may have an unusual cry that has a very high pitch.

Muscle Tone

A baby with kernicterus may have floppy or weak limbs. They may also arch their backs or heads in an abnormal manner.

Brain Damage

Permanent brain damage due to kernicterus may also cause learning problems or other developmental delays. Other symptoms of brain damage include uncoordinated movements, hearing loss and difficulty moving the eyes.
