Attention‐deficit/hyperactivity disorder (ADHD) frequently co‐occurs with other psychiatric disorders. Twin studies have established that these co‐occurrences are in part due to shared genetic risks. However, the strength of these genetic overlaps and the potential heterogeneity accounted for by type of psychiatric symptoms, age, and methods of assessment remain unclear. We conducted a systematic review to fill this gap.

研究综述：多动症和其他精神症状之间遗传重叠的强度——系统综述和荟萃分析

注意缺陷/多动障碍 (ADHD) 经常与其他精神疾病同时发生。双胞胎研究已经确定，这些共同发生的部分原因是共同的遗传风险。然而，这些遗传重叠的强度和由精神症状类型、年龄和评估方法引起的潜在异质性仍不清楚。我们进行了系统评价以填补这一空白。
