发展性计算障碍（DC）在学校人口中的患病率为3- 6%，与发展性阅读障碍和ADHD的频率相似。这些研究符合充分流行率研究的标准，即，以人口为基础，使用标准化的措施来评估算术功能。虽然患病率的变化是在一个狭窄的范围内，差异可能是由于计算障碍的定义被使用，诊断的年龄和仪器选择测试DC。DC女孩的相对优势可能反映了更大的脆弱性，环境的影响单独或除了生物易感性。DC不仅是一种特殊的学习障碍，而且在各种神经系统疾病中也会遇到，这些疾病的例子包括ADHD、发育性语言障碍、癫痫、治疗性苯丙酮尿症和脆性X综合征。虽然DC的长期预后尚不清楚，但目前的数据表明，DC是一种稳定的学习障碍，至少在短期内持续存在于约一半的受影响儿童中。DC的长期后果及其对教育，就业和心理健康的影响尚未确定。
The prevalence of developmental dyscalculia (DC) in the school population ranges from 3–6%, a frequency similar to that of developmental dyslexia and ADHD. These studies fulfilled the criteria for an adequate prevalence study, i.e., were population based, using standardized measures to evaluate arithmetic function. Although the variation in prevalence is within a narrow range, the differences are probably due to which definition of dyscalculia was used, the age the diagnosis was made and the instrument chosen to test for DC. The relative predominance of girls with DC may reflect a greater vulnerability to environmental influences alone or in addition to a biological predisposition. DC is not only encountered as a specific learning disability but also in diverse neurological disorders, examples of which include ADHD, developmental language disorder, epilepsy, treated phenylketonuria and Fragile X syndrome. Although the long-term prognosis of DC is as yet unknown, current data indicate that DC is a stable learning disability persisting, at least for the short term, in about half of affected children. The long-term consequences of DC and its impact on education, employment and psychological well-being have yet to be determined.
