Sponsor's own description

Among risk factors of neurodevelopmental disorder is congenital hearing loss. However, congenital deafness is neither necessary nor sufficient for the occurrence of warning signs of neurodevelopmental disorder. The investigative team hypothesizes that the co-occurrence of these two clinical entities results from a common origin, within a syndromic diagnosis including other medical issues. These situations would therefore be very different from those of babies suffering from isolated sensorineural deafness. This study aims to identify which factors are statistically correlated with the association of congenital deafness and early symptoms of neurodevelopmental disorder, thanks to a partnership between a regional center for psychiatry of deaf children (Therapeutic Childhood and Deafness Unit of St Maurice Hospitals, UTES) and a pediatric audiophonology department (ENT department of the Necker-Enfants Malades hospital). This work is based on a cohort of 26 children under ten months of age diagnosed with severe to profound congenital sensorineural hearing loss. As part of their pre-implantation cochlear assessment, a consultation was filmed to precisely analyze the interactional and sensorimotor skills of these children (clinical observations, administration of a specific evaluation grid called Olliac Grid), after reviewing the films. The investigative team will then be able to grade the neurodevelopmental risk. In order to clarify what factors are linked with a neurodevelopmental risk, medical data concerning the child's family context, birth, and audiological profile will also be collected, and put in perspective with the assessed neurodevelopmental risk gradation.
