This crossmodal activation is interpreted as the reallocation of more attentional resources to the visual domain as well as deficient sensory inhibition. There is evidence that the visual cortex shows more activation during a focused auditory task in adults with ADHD than in healthy controls. It has further been shown that deficiencies not only exist on an intramodal, but also on a multimodal level. For example, during the processing of auditory stimuli comparable low sensory thresholds account for symptoms like higher distractibility and auditory hypersensitivity in patients with ADHD. In order to understand the basis for this multifaceted disorder, the investigation of sensory processing aberrancies recently reaches more interest. 4Center of Brain, Behavior and Metabolism (CBBM), University of Lübeck, Lübeck, Germanyīackground: Attention deficit and hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by core symptoms of inattention, and/or impulsivity and hyperactivity.3Department of Psychology, University of Lübeck, Lübeck, Germany. 2Department of Neurology, University of Lübeck, Lübeck, Germany.1Department of Psychiatry and Psychotherapy, University of Bonn, Bonn, Germany.Mia Schramm 1 * Tatiana Goregliad Fjaellingsdal 2,3,4 Behrem Aslan 1 Paul Jung 1 Silke Lux 1 Marcel Schulze 1 † Alexandra Philipsen 1 †
