目的　探索研究 ADHD的发病机理及各种治疗方法的效果。方法　采用心理学的内省法观察记录成人 ADHD者心灵的运行状态及各种疗法对心灵运行状态的影响。结果　引发 ADHD一系列临床表现的直接原因是由于意识活动困难(这是一种意识活动无法连续运行 ,意识活动频繁停顿的现象 )。结论　意识活动困难是否得到根本改善是衡量一种治疗方法是否有效的最重要尺度 ,应该重新认识和评价各种治疗方法和药物。把注意力分散、多动、冲动的改善与否作为治疗是否有效的最重要尺度的观点是错误的 Objective To explore the pathogenesis of ADHD and the effects of various treatment methods. Methods The introspective method of psychology was used to observe and record the mental status of adults with ADHD and the effects of various therapies on the psychic status. Results The direct cause of a series of clinical manifestations of ADHD was due to difficulty in awareness activities (a phenomenon in which conscious activities can not run continuously and consciousness activities are frequently stopped). Conclusions Whether the difficulty of awareness activity can be fundamentally improved is the most important measure of whether a treatment method is effective or not, and it is necessary to re-understand and evaluate various treatment methods and drugs. The view that distractions, hyperactivity, impulse improvements are the most important measures of the effectiveness of treatment is erroneous
