The clinical picture of attention deficit hyperactivity disorder(ADHD) is inattention, hyperactivity, and impulsivity. Five databases were searched for empirical research on ADHD in Taiwan, including the National Central Library National Digit Library in Taiwan, Electronic Theses and Dissertations System in Taiwan, Chinese Electronic Periodical Services (CEPS), Medline, and PsycInfo. Moreover, some empirical research participants on ADHD were Chinese (mainly, China) in CEPS, Medline, PsychInfo, and these were also discussed for comparison.
A review of the literature showed: (1) the range of prevalence was too wide, (2) the types of comorbidities and accompanying problems were too many, (3) many genes were related to ADHD, but most were of uncertain value, (4) many rating scales were reliable and validated, but the discriminality of standardized tests for ADHD were unfair, and (5) there were too many treatments, although all treatments were effective. All of these results show ADHD as heterogeneous such that researching ADHD in Taiwan was increasingly difficult. Finally, future avenues of research is discussed as well as how the heterogeneity of ADHD can be reduced from a neurodevelopmental perspective. All contents of the research will be very different.
