2007年,美国肯尼迪·克里格研究所(Kennedy Krieger Institute )的儿科神经学家Andrew W. Zimmerman向导的研究组,跟踪了30名2-18岁的自闭症个体在发烧期间(38度)、发烧消退期和无发烧7天后的举动,发现高达83%的受试自闭症儿童在对视、专注力和语言本领等方面都得到改善 [6]。研究中的数据网络是让家长填写举动异常量表(ABC量表),对个体的举动举行评估。只管作者强调,研究中并没有告知家长该研究的目标是试图证明发烧能够改善自闭症人士的举动,但是Zimmerman本身后来也承认,家长在陈诉数据时,肯定会受到广为流传的发烧能改善自闭症人士举动的说法影响,因而数据的客观性有短缺,83%的结论应该是有水分的 [7,8]。
当然,样本量比较小也是上述研究的重要缺陷。为此,加州大学洛杉矶分校(UCLA)传授 Catherine Lord 向导的研究小组,分析了西蒙斯基金会数据库(Simons Simplex Collection,SSC)2152名自闭症儿童的信息,发现此中17%的儿童家长确认,他们的孩子在发烧期间举动得到了提高。进一步分析这些数据发现,发烧期间举动得到改善的孩子,大部门都是自闭症程度比较严峻的孩子,例如语言本领不敷、较低的非语言智商、自闭症特质严峻,存在严峻的重复刻板举动、不符合的语言、多动和感情易变等环境。因而,文章据此推测,可能有某个亚型的自闭症儿童,特殊是程度严峻、语言交流本领不够的儿童,在发烧的时间举动得到改善。遗憾的是,比较他们的基因信息,并没有发现这些儿童有特定的相同基因变异,因而也无法确定任何的自闭症亚型 [9,10]。
2014年,Andrew W. Zimmerman(这篇论文的通讯地点为麻省大学医学院儿童神经科和哈佛医学院麻省儿童总医院儿科自闭症中央)和约翰·霍普金斯大学的 Paul Talalay 传授合作,由Talay传授儿子的公司提供了富含萝卜硫素的西兰花籽芽提取物制成的胶囊,举行了一个小型(40名13-27岁的男性)的临床双盲对照实验,效果发现,到场受试的自闭症人士,他们的举动都得到了差别程度的改善 [13]。
