Reading Disability (RD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are the two most prevalent disorders of childhood, and these two disorders frequently co-occur. The overall goal of the proposed research is to refine our understanding of the diagnostic validity, etiology and neuropsychology of ADHD in order to understand how ADHD contributes to RD. To accomplish these objectives, an extensive psychometric test battery will be administered to a sample of 50 pairs of identical twins and 50 pairs of fraternal twins in which at least one member of each pair is reading disabled, to an independent sample of 50 pairs of identical twins and 50 pairs of fraternal twins in which at least one member of each pair has ADHD, to a comparison sample of 50 pairs of identical twins and 50 pairs of fraternal twins with no school history of reading deficits or ADHD, and to the siblings of all twin pairs. The test battery includes multiple measures of executive functions, orbital frontal cortex functioning, and processing speed. A well-validated diagnostic interview and a battery of rating scales will also be administered to parents and teachers of each twin and their siblings to assess ADHD and comorbid internalizing and externalizing symptoms. DNA will be collected from each twin and sibling and all biological parents, and these phenotypic and genotypic data will be used to conduct univariate and bivariate twin, linkage, and candidate gene analyses to identify quantitative trait loci that influence ADHD and its comorbidity with RD.

阅读障碍（RD）和注意力缺陷/多动症（ADHD）是两个最普遍的 童年的疾病，这两种疾病经常同时发生。拟议的总体目标 研究是为了完善我们对ADHD的诊断有效性，病因和神经心理学的理解 为了了解多动症如何为RD贡献。为了实现这些目标， 心理测试电池将用于50对相同双胞胎和50对的样本 兄弟双胞胎，其中至少有一个成员正在禁用读书， 50对相同的双胞胎和50对兄弟双胞胎，其中至少一个成员具有 多动症，进行50对相同双胞胎和50对兄弟双胞胎的比较样本，没有学校 阅读缺陷或多动症的历史，以及所有双子对的兄弟姐妹。测试电池包括多个 执行功能，轨道额叶皮层功能和处理速度的度量。验证的 诊断面试和一系列评级量表也将向每个人的父母和老师进行管理 双胞胎及其兄弟姐妹评估多动症和合并症的内在化和外在化症状。 DNA会 从每个双胞胎和兄弟姐妹以及所有亲生父母中收集，这些表型和基因型数据将 用于进行单变量和双变量双胞胎，连锁和候选基因分析以识别 影响多动症的定量性状基因座及其与RD的合并症。
