With point of departure in a phenomenological analysis of the body as it is described and conceptualized in the diagnosis of Attention-Deficit/Hyperactivity Disorder, this paper argues that the diagnosed behavior associated with bodily movement exposes an often-neglected expressive aspect of the body. Beyond the pre-reflective dimension of the experiential body, it is argued that the expressive dimension of the body is associated with movement as a utopian or an incorporeal aspect immanent to the body. In this perspective, the phenomenological notion of the body is critically connected to a fundamental question of the materiality of sensation, which calls for a rethinking of the Attention-Deficit/Hyperactivity Disorder-diagnosed body that gives privilege to the aesthetic and expressive aspects of sensation.
