In this retrospective case series, the longitudinal trajectories of receptive language, expressive language, and vocabulary acquisition during auditory processing training (APT) were described for seven individuals with different neurodevelopmental characteristics. The study aims to highlight intra-case developmental patterns rather than to assess the intervention's effectiveness.

Discussion
Signed responses from readers of the wire.
No actionable change; this retrospective case series provides preliminary, low-confidence evidence only — audiologists should not alter auditory processing training protocols on the basis of this study alone.
Evidence for long-term language benefits of auditory processing training in neurodevelopmental populations is sparse, and even preliminary data from case series can inform the design of more rigorous future trials.
- 01Retrospective case series design — among the lowest levels of clinical evidence.
- 02Participants had neurodevelopmental disorders (e.g., autism, ADHD, or similar conditions).
- 03Training targeted auditory processing skills (how the brain interprets sounds).
- 04Outcomes measured included receptive language (understanding words) and expressive language (producing words).
- 05Longitudinal data collected, but lack of control group limits causal interpretation.
Long-term auditory processing training improves receptive and expressive language outcomes in individuals with neurodevelopmental disorders.
