cochlear implant baby hearing loss

More “Yeah” for Cochlear Implants!!!

I have cheered cochlear implants for many years as everyone knows. When cochlear implants first came out I did not believe that they could possibly work. I thought “what a ridiculous idea.”  I have laughed at myself a lot about this. CI’s have changed the lives of so many people that is it difficult to believe. Clinically I have seen the benefits.

More and more research continues to confirm the benefits.


Max Planck institute for Human Cognition and Brain Sciences


The Max Planck institute is a good clinical/research center in Germany. Recent research has demonstrated that children with cochlear implants learn words faster than children with hearing. WOW!!!

A recent study the Max Planck Institute evaluated how children with cochlear implants learn compared to their hearing peers. Scientists analyzed the brain activities of children with cochlear implants using EEG. The children were fitted with caps with electrodes so brain activity could be measured while learning words.

Previous studies had shown that children with cochlear implants need longer to attain language and to distinguish their mother language from other languages. They seemed less ready to start school.


Do they benefit from their older age?


The current study demonstrated that when children get their cochlear implants they learn words at a faster rate than their hearing peers. So they build up pools of words faster. The researchers think this may be because children with cochlear implants have more general knowledge. For example, they know what a cup is for before they know the word. They know that food can be hot and that they need to be careful before they know the word hot.


The study


The neuroscientists at the Max Planck institute studying 32 children with bilateral cochlear implants. They tested then at 12, 18 and 24 months after implantation. They tested their ability to recognize words. They were shown pictures of objects which were either named correctly or incorrectly. They were able to monitor brain activity to know if the child recognized the incorrect word – meaning that they had learned the word. They report that age does not affect how fast children learn words. They seem to catch up even if learning words late.

However, feel the need to point out that these were still very young children. While this is good news, we should not extrapolate to children who are significantly older. There is no evidence that a child who is 8 or 10 or older could develop these listening skills.

  1. You should read Professor Clark book!!! Hes so clever! Others called him clown but he proved people wrong! I’m profoundly deaf since birth 1970s and dad to my 9 yrs old bilateral ci son implanted at 8 and 15 mths old. He speaks very clear speech! He goes mainstream school with no sign language and he knows sign language not large and he jumped to interpret for me without ask him at all!!! Wow!!! He refused to sign at mainstream school!
