These appear as risk markers before formal reading begins.","answer_md":"*A child's reading brain is built from many threads — genetic, linguistic, and environmental — woven together long before the first word is decoded.*\n\n## In short\nDyslexia (ICD-11 6A03.0) is a neurodevelopmental difference in accurate, fluent word reading and spelling, not a deficit of intelligence or effort. Its aetiology is multifactorial: a strong heritable component interacting with phonological-processing differences and environmental literacy exposure. In early childhood these contributors are observable as risk markers well before formal reading begins.\n\n## The contributing factors\n**Genetic and familial** — Heritability is substantial; a first-degree relative with reading difficulty markedly raises risk. Multiple susceptibility loci affect neuronal migration and cortical organisation of left-hemisphere reading networks.\n\n**Neurobiological** — Atypical activation in the left temporoparietal and occipitotemporal regions, with weaker phonological–orthographic integration. These differences predate instruction rather than result from it.\n\n**Cognitive-linguistic precursors** — Weak phonological awareness, slow rapid automatised naming (RAN), reduced verbal short-term memory, and delayed letter-knowledge acquisition are the most robust early predictors.\n\n**Speech and language** — Early expressive/receptive language delay and persistent speech-sound difficulties co-travel with later reading impairment.\n\n**Environmental modifiers** — Limited print and shared-reading exposure, low-quality early instruction, and multilingual demands without structured support can amplify expression of underlying risk (though they do not cause dyslexia).\n\n**Perinatal** — Prematurity and very low birth weight add modest additional risk.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online form.

identifying and supporting learning difficulties; ASHA resources on the language basis of reading.\n\n**Next step —** Refer a child with family history or weak phonological awareness for a structured
