Early vocabulary size is genetically linked to ADHD, literacy, and cognition

The article stresses early language's key role in shaping children's linguistic, reading, and learning skills, linking language issues to ADHD and ASD. Researchers studied genetic influences on infant and toddler vocabulary, revealing their impact on word comprehension, literacy, cognition, and ADHD symptoms.

The study differentiates between "learning to speak" and "speaking to learn" phases, showing how early vocabulary reflects cognitive processes and predicts future outcomes. It suggests a dynamic link between genetics and language development, with implications for understanding both typical and atypical language acquisition.

In summary, the research highlights the intricate interplay of genetics, early language, and later cognitive and behavioral development, urging early intervention for neurodevelopmental challenges in children.
