New research on the underlying cause of dyslexia could pave the way for earlier diagnosis and intervention.
Dyslexia is a common learning difficulty that affects one in every 10 to 20 people, impacting their ability to read and spell words but not affecting their general intelligence.
The new finding expands knowledge of the brain mechanisms underlying the condition.
Humans have a type of long-term memory (called “implicit memory”) that means we respond less to stimuli as they are repeated over time, in a process called neural adaptation.
But the new research suggests that dyslexics recover faster than non-dyslexics from their responses to stimuli such as sounds and written words, leading to their perceptual and reading difficulties.
