Babies with this condition need to be preserved immediately to bring down their bilirubin ranks and avert further brain injury.

The body harvests bilirubin when old red blood cells are not working. Once free in the circulation, bilirubin is taken up by the liver, made water-soluble, then defecated into bile salts. Bilirubin is then worn-out by duodenal bacteria. It then either shrubberies the body in the feces or is related to the kidneys and aloof from the body in urine. In neonates, the body parts may not be settled enough to route bilirubin, particularly in the initial few hours and days of life. This can outcome in jaundice.

Dubin-Johnson syndrome: An erratic, genetic disorder that averts the body from efficiently removing bilirubin. This situation does not cause kernicterus.

Crigler-Najjar syndrome: An inborn disorder that makes it stiffer for the body to break bilirubin.

Rotor syndrome: An inherited disorder that causes bilirubin levels to debris in the blood. This disorder does not root kernicterus.

Gilbert’s syndrome: An illness in which the liver can’t appropriately progress bilirubin.

Causes of Kernicterus:

Kernicterus transpires when bilirubin levels in the blood become so high that it crosses the blood-brain barricade and indemnities the brain tissue. The situation is almost always connected to plain jaundice.

  • Damaged liver, underdeveloped or diseased
  • Untimely birth, typically before 37 weeks of gestation or pregnancy
  • The Devastation of red blood cells, often when the mother’s blood type does not match her baby’s

Blood transfusion:

This is done if a baby isn’t retorting to other cures and it’s essential to rapidly inferior their bilirubin level. It’s only done if a baby is presenting signs of brain injury from too much bilirubin.


Kernicterus is effortlessly curable when identified and pickled early enough, or while tranquil in its trivial forms. Once kernicterus has transpired, however, the subsequent glitches are usually enduring, though some may diminish or get away with treatment, medication, or in maturity.
