背景:多动症的触觉敏感性和感觉超负荷在临床上有很好的记录,self-,和家长报告,但是经验证据很少且含糊不清,主要集中在儿童身上。这里,我们比较了成人ADHD患者和神经典型对照组的经验和自我报告的触觉敏感性和ADHD症状学.我们评估了触觉敏感性和整合在ADHD中是否更普遍,以及是否与ADHD症状严重程度有关。
方法:在四种情况下(休息,抚摸自己的手臂,研究人员抚摸手臂,和物体的抚摸)。参与者还填写了有关触觉敏感性和ADHD症状的问卷,并进行了Qb测试,以客观衡量ADHD症状的严重程度。
结果:患有ADHD的参与者自我报告的触觉敏感性和ADHD症状严重程度高于对照组,并且在Qb测试中获得了更高的分数。这些值彼此相关。ADHD参与者表现出较低的可容忍阈值,在与ADHD症状相关的其他触觉刺激期间,皮质SEP振幅降低更大。
结论:我们发现ADHD症状学和触摸敏感性有直接联系,使用自我报告和实验措施。我们还发现了多动症中触觉感觉超负荷的证据,这表明这与注意力不集中有关。触觉敏感性和感觉超负荷影响许多多动症患者的功能和生活质量,临床医生在治疗患者时应该考虑这一点。
BACKGROUND: Tactile sensitivity and sensory overload in ADHD are well-documented in clinical-, self-, and parent- reports, but empirical evidence is scarce and ambiguous and focuses primarily on children. Here, we compare both empirical and self-report tactile sensitivity and ADHD symptomatology in adults with ADHD and neurotypical controls. We evaluate whether tactile sensitivity and integration is more prevalent in ADHD and whether it is related to ADHD symptom severity.
METHODS: Somatosensory evoked potential (SEP) amplitudes were measured in 27 adults with ADHD and 24 controls during four conditions (rest, stroking of the own arm, stroking of the arm by a researcher, and stroking of an object). Participants also filled out questionnaires on tactile sensitivity and ADHD symptoms and performed a Qb-test as an objective measure of ADHD symptom severity.
RESULTS: Participants with ADHD self-reported greater tactile sensitivity and ADHD symptom severity than controls and received higher scores on the Qb-test. These values correlated with one another. ADHD participants showed lower tolerable threshold for electrical radial nerve stimulus, and greater reduction in cortical SEP amplitudes during additional tactile stimuli which was correlated with ADHD symptoms.
CONCLUSIONS: We find that ADHD symptomatology and touch sensitivity are directly linked, using both self-reports and experimental measures. We also find evidence of tactile sensory overload in ADHD, and an indication that this is linked to inattention specifically. Tactile sensitivity and sensory overload impact the functioning and life quality of many people with ADHD, and clinicians should consider this when treating their patients.
