Desarrollo lingüístico de un caso de sordera prelocutiva más trastorno por déficit atencional (TDAH)

This article retrospectively describes language development in a prelocutive deaf girl who was enrolled in a long-term longitudinal study. The main aim was to study the effect of the simultaneous use of an early cochlear implant (CI) and cued speech (CS). From 15 months to 6 years old the child underwent rehabilitation in the complemented oral model [COM, Modelo Oral Complementado (MOC) in Spanish]. During this period, 159 sessions of 30-minutes each were videotaped, forming the MOC-CORPUS, available in the CHILDES database. Prelinguistic acquisitions (canonical babbling, phonetic inventory, and first words), and linguistic development (phonology, lexicon, grammar and pragmatics) were explored. As the child's linguistic development did not follow the expected course for a case of deafness with CI+CS, other hypotheses were investigated. After 4 years of CI use, attention-deficit hyperactivity disorder (ADHD) was confirmed and was treated with methylphenidate. The data were reanalyzed from the perspective of deafness plus ADHD, assuming that both disorders were present from the beginning. The differential features in linguistic development in cases of typical deafness versus deafness plus ADHD are contrasted.
