Early brain development and plasticity in dyslexia

Early brain development and plasticity in dyslexia.

PI’s Teija Kujala, Paula Virtala

Time frame 2014-2022

Description The project aims to study the auditory and language development of individuals with a genetic risk for dyslexia from birth until school-age with neural, behavioural, and genetic measures. Additionally, the project tests the effects of early music-based interventions on preventing and/or ameliorating problems related to language, reading and writing abilities in children at-risk for dyslexia. This longitudinal project will illuminate normal language development, influence of dyslexia risk on this development, and effects of early intervention on language and reading skills. If proven effective, the intervention program may help to improve the developmental path in language and reading-skill acquisition of children world-wide in the future.

Methods Event-related potentials (ERP), the mismatch negativity (MMN), electroencephalography (EEG), neuropsychological/perceptual/cognitive/behavioral tests, gene analysis

Keywords dyslexia, language development, music intervention, auditory development, speech processing
