Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The principal aim of this study is to evaluate the cortical developement of perceptual skills and executive functions over time, in children with cochlear implants aged 10-24 months and 3-7 years compared with normally hearing subjects (NHS). To do this, the investigator will use functional Near InfraRed Spectroscopy (fNIRS) during 4 tasks that engage the childs perceptual and cognitive skills over a period of 18 months. The performance scores obtained by each participants as well as the cortical activity will be analysed and decrypted.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

When confronted with a severe to profound congenital bilateral hearing loss, cochlear implantation is considered to be the preferential treatment method as it restaures auditory function and enables language acquisition for communication purposes. When cochlear implantation is done before 2 and a half years old, better results are obtained in terms of language, communication and social developement, as well as reading skills. However when a cochlear implantation occurs between 2 and 5 years of age, speech and language skills do develop but communication and reading skills are altered. Therefore, when a cochlear implant is placed before the age of 2 and a half we find ourselves within the maximal cerebral plasticity window for speech, language and communication developement.

This study is divided into two cohorts, the first aged 10-24 months and the second 3-7 years. All children will be seen for 5 sessions, spread out at regular intervals, over a period of 18 months and will participate in two perceptual tasks and two cognitive tasks. The children will also have a speech and language assessment at T-0 and T+12. The cochlear implanted patients will continue to be seen by the ENT service and the sessions will be organised to coincide with their natural follow up. As it is a non-interventional study, no follow-up would be needed. After the study patients will continue to receive the same quality of care.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Severe/profoundly deaf children 10-24 months old

The cohort 1 includes patients aged 10-24 months old about to be implanted

Group Type EXPERIMENTAL

Near InfraRed Spectroscopy (fNIRS)

Intervention Type DEVICE

Functional neuroimaging examination by fNIRS at each follow-up visit for all children of both cohorts: this non-invasive imaging technique involves the installation of a cap carrying electrodes to collect brain activity on the surface of the scalp , during stimulation. It is very insensitive to movement and therefore represents a method particularly suitable for its use in children. In addition, this technique is compatible with the cochlear implant. It will be used during 6 tasks adapted to each cohort

Passive perceptual stimulation

Intervention Type BEHAVIORAL

Passive perceptual stimulation: For this passive task the child is on his parents' lap in front of a screen. He will see images, hear everyday noises and watch small videos. Duration 8-10 minutes.

Task A not B

Intervention Type BEHAVIORAL

Task A not B: the child will play with an adult who will hide an object under a cloth several times. The child will have to find the hidden object. Duration 10 minutes maximum

VSWMT task

Intervention Type BEHAVIORAL

VSWMT task: the child will be on the parents' lap in front of a screen and will watch a monkey hiding bananas in the trees several times. Duration of 10 minutes maximum.

The sensory room

Intervention Type BEHAVIORAL

The sensory room: the child will sit in the middle of a carpet and play with the adult. He will hear everyday noises and see light effects. Duration 8-10 minutes

Severe/profoundly deaf children 3-7 years old

The cohort 2 includes 3-7 years old cochlear implanted patients (implanted before 24 months of age)

Intervention Type BEHAVIORAL

Perceptual Go-No-Go: This perceptual task consists in the discrimination of images (faces) and sounds (words) through 3 conditions (auditory, visual and visuo-auditory) presented independently of each other and lasts 15 to 20 minutes in total. It is presented by means of a computer

Verbal memory task

Intervention Type BEHAVIORAL

Verbal memory task :the child will be presented with 5 lists of 5 words which he will have to restore after a predefined delay of a few seconds. Its duration does not exceed 10 minutes.
