Preschool Children with Minimal and Mild Hearing Loss
What is it about?
This study aimed to investigate the current status of cognitive development and central auditory processing development of preschool children with minimal and mild hearing loss (MMHL) in Nanjing, China. We recruited 34 children with MMHL and 45 children with normal hearing (NH). They completed a series of tests, including cognitive tests, behavioral auditory tests, and objective electro-physiological audiometry. In addition, teacher evaluations and demographic information and questionnaires completed by parents were collected.
Why is it important?
Children with minimal and mild hearing loss are already at increased developmental risk as early as preschool. They are more likely to have problems with attention and verbal comprehension than children with normal hearing. This condition is not compensated with increasing age during the preschool years. The results suggest a possible relationship between the risk of cognitive deficit and divergence of auditory processing.
