Multimodal imaging of parietal brain networks in adults and children with developmental dyscalculia

据估计，3-6%的儿童和成人患有发展性计算障碍（DD）。数学能力受损会给个人带来相当大的损失。例如，最近的政府科学展望办公室项目精神资本和福祉（2008年）估计，患有发展性计算障碍的人一生的收入减少了114,000英镑，获得5个或更多普通中等教育证书（A*-C）的可能性降低了7 ？20%。社会也有成本，因为患有计算障碍的人失业的可能性是未受影响的人的两倍，并且潜在的心理健康成本，因为据估计，患有计算障碍的人患抑郁症的风险增加了3倍（Butterworth, 2008）。更好地了解计算障碍的潜在原因将提高我们在生命早期发现有风险的人的能力，并改善我们可以提供的补救措施。我们的项目应该提供(1)比目前可用的DD更详细的理论理解，(2)DD识别方法的明确建议，(3)开发DD补救的潜在途径。

It is estimated that 3-6% of children and adults have Developmental Dyscalculia (DD). Impaired mathematical skills have a considerable cost to the individual. For example, the recent Government Office for Science Foresight project Mental Capital and Wellbeing (2008) estimated that having developmental dyscalculia reduced lifetime earnings by #114,000 and reduced the probability of achieving 5 or more GCSEs (A*-C) by 7 ? 20 percentage points. There is also a cost to society, as those with dyscalculia are twice as likely to be unemployed as non-affected individuals, and a potential mental health cost, as it has been estimated that having dyscalculia raises the risk of depression 3-fold (Butterworth, 2008). Having a better understanding of the underlying causes of dyscalculia would improve our ability to detect early in life who is at risk, and also improve the remediation that we can offer. Our project should provide (1) a much more elaborate theoretical understanding of DD than currently available, (2) clear recommendations for identification methods for DD, (3) potential avenues for developing remediation for DD.
