Abstract

Attention Deficit Hyperactivity Disorder is a widely spread diagnosis.The dominant paradigm of ADHD is biomedical where ADHD isdefined as a brain disorder. At the same time, the legitimacy of thediagnosis is being questioned since it is unclear whether or not ADHDcan be deemed a medical disorder in itself. The aim of this article is tocritically assess the merits of understanding the diagnosis of ADHD as amedical condition defined as a brain disorder. This is being done usingthe seventeenth century philosopher Benedict Spinoza’s notions of adequate and inadequate knowledge and his counterintuitivetheory of mental health. Doing so it becomes clear that ADHD, howeveradequate it may seem, is founded on inadequate knowledge and thatthe legitimacy of the individual diagnosis should therefore be questionedon the grounds that on a long term scale it is passivizing andstigmatizing rather that liberating.
