Abstract

Introduction: Communication is an essential human ability that facilitates relationships, enhances understanding, and promotes development across all areas of life. Hence, developmental stuttering interferes with the fluency of speech, which may impair children's reading abilities.
Objective: Our study aimed to ascertain the prevalence of dyslexia in children with developmental stuttering and the relationship between the two conditions.
Methods: Our study was conducted on two hundred children, divided into two groups: one hundred children with developmental stuttering and one hundred with typical fluent speech. Demographic data were collected with a focus on stuttering symptoms. Speech samples, Stuttering Severity Index, and the Arabic Reading Test were administered to all children.
Results: Highly statistically significant differences were observed between the two groups in nearly all subtests of the Arabic Reading Test, including phonological awareness, auditory perception, short-term memory, comprehension, spelling subtests, and the total ART score p<0.001). Additionally, a substantial negative correlation between the severity of stuttering and ART scores was observed.
Conclusion: Dyslexia occurs at a significantly higher rate in children who experience developmental stuttering. This speech disorder is linked to deficits in phonological awareness, short-term memory, and phonological processing, which elevate the likelihood of dyslexia in these children.
