Despite a high rate of concurrent mathematical difficulties among children with dyslexia, we still have limited information regarding the prevalence and severity deficits in this population. To address gap, developed comprehensive battery cognitive tests, known as UCSF Mathematical Cognition Battery (MCB), aim identifying four distinct domains: number processing, arithmetical procedures, arithmetic facts retrieval, geometrical abilities. The abilities cohort 75 referred to Dyslexia Center diagnosis along 18 typically developing controls aged 7 16, were initially evaluated using behavioral neurology approach. A team professional clinicians classified dyslexia into five groups, based on parents' teachers' reported symptoms clinical history. These groups included no or Subsequently, underwent evaluation MCB determine concordance clinicians' impressions. Additionally, neuropsychological standardized tests administered. Our study reveals that within 66% exhibit deficits, those there is heterogeneity nature these deficits. If findings are confirmed larger samples, they can potentially pave way for new diagnostic approaches, consistent subtype classification, and, ultimately personalized interventions.
