Causes of Congenital Hearing Loss

Too many people associate hearing loss strictly with old age. But hearing loss in children is far more common than most people suppose, affecting as much as 15% of people. Whenever a child is born with hearing loss, we refer to it is as ‘congenital.’ You might wonder: what causes congenital hearing loss? Today, we’ll break the causes down into two basic categories, and give some examples of each.

Congenital hearing loss isn’t necessarily genetic. Here’s what you need to know about hereditary and non-hereditary hearing loss in children.


When most people hear the word ‘congenital,’ they assume it means ‘hereditary.’ But this is not always the case. Frequently, children with congenital hearing loss lack the genes associated with hearing loss, but experience symptoms of it anyway. These individuals fall into our first category: non-hereditary congenital hearing loss.

Here are some of the most common causes:

  • Maternal infections, including herpes simplex and rubella
  • Various birth injuries
  • Fetal alcohol syndrome
  • Maternal drug use during pregnancy

Non-hereditary congenital hearing loss is admittedly less common than the alternative, but it does happen. It accounts for roughly 25% of instances of hearing loss in children. But what exactly is the alternative?


As you might have guessed, the other major form of congenital hearing loss is hereditary. This means that we can attribute the hearing loss to a particular genetic defect. Hearing loss has an especially strong correlation with the following disorders:

  • Usher syndrome
  • Alport syndrome
  • Waardenburg syndrome
  • Down syndrome

Hereditary congenital hearing loss does not occur due to the actions of a particular individual, such as a pregnant mother or negligent medical professional. On the contrary, a quirk in the DNA of one or more parents results in a reduction in hearing ability.
