PMID 40059097WHAT IT FOUND
At age 9, children who received cochlear implants earlier showed stronger verbal short-term memory, which linked to better language and quality of life.
Hearing aid fitting age had little effect. This supports fast-tracking cochlear implant referrals for children who need them.
Key findings
01Verbal short-term memory acts as a mediator: better memory is associated with earlier cochlear implant activation, and in turn with better speech perception, language, and quality of life.
02For children using hearing aids, the age at first fitting had little effect on outcomes at 9 years, likely because most children with severe loss had already received cochlear implants.
03Children with additional disabilities showed weaker quality of life and language outcomes, mediated through their impact on cognitive abilities and speech perception.

What it does not show
The study is observational, so it cannot prove causation. Findings cannot be generalized to children who use sign language or other non-spoken communication modes. Data were missing for some participants, with conclusions based on 70–85% of the cohort across different measures. The age at hearing aid fitting effect may be masked because most children with severe hearing loss had already received cochlear implants.
Declared interests
The study was supported by the National Health and Medical Research Council of Australia. The authors declared no conflicts of interest.
The easy way to misread this
Do not assume that delaying hearing aid fitting is harmless. The lack of effect on outcomes at age 9 may be because children with severe hearing loss had already received cochlear implants, masking the benefit of early amplification for that specific group.
