The article examines the manner in which the learning-disabled subject is created as an object within contemporary psychiatric discourse by means of a genealogical analysis of the learning-disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM). It investigates how this pathology was formed historically in the text, what metamorphoses it underwent, and their epistemic significance. First, the theoretical underpinnings of the sociological discourse on DSM are presented, giving a brief background of the DSM status in the Israeli context. Many problematic characteristics in the text are unveiled, by means of critiques from sociology, anthropology and discourse studies. Second, the changing definitions and conceptualizations of learning-disorders in the seven editions of the Manual and the accompanying case studies (1952-2013) are examined. It becomes apparent that the disorders have undergone changes that have enabled the biomedical paradigm to triumph. The implications of these transformations are addressed.
