ClinConnect Summary

This clinical trial is studying how cochlear implants, which help children with severe to profound hearing loss, affect their ability to perceive sounds and think over time. The researchers want to understand how the brain develops these skills in young children with cochlear implants, compared to children who can hear normally. They will use a special tool called functional Near Infrared Spectroscopy (fNIRS) to measure brain activity while children complete tasks that challenge their thinking and listening abilities over 18 months.

To participate in this study, children must be between 10 months to 7 years old and have parental consent. There are two groups: one for children aged 10-24 months who are about to receive a cochlear implant, and another for children aged 3-7 years who already have one. Participants need to have a specific type of hearing loss or be normally hearing, confirmed by a simple hearing test. Throughout the study, children will engage in activities while their brain responses are recorded, helping researchers learn more about how cochlear implants can improve hearing and cognitive functions in young children.
