This article explores the complicated relationship between feminism and women’s mental health. I discuss the differences and convergences between neurodiversity and mental health and how feminist theory has approached these topics. While contrasting the pathologisation that mental health disciplines can apply to women, feminism has often reduced mental health conditions to mere manifestations of patriarchy. Using autism as a prism, I propose that the neurodiversity paradigm can be a means to discuss diverse brain and mind experiences without reinforcing pathologisation. The choice of autism has two motivations: while autism is a neurological difference and not a mental illness, the complex experiences of autistic women exemplify their otherness and exclusion, highlighting the marginalisation of women with atypical brains not just in society but also in feminist theories and practicesDrawing on documentary sources and discussing theoretical approaches from the UK, the USA, and, to a lesser extent, other English-speaking countries, this article aims to advance the feminist discourse on mental health. I illustrate the necessity to enrich feminist perspectives on mental health and suggest ways to make feminist theories and practices more inclusive of neurodivergent and mad women.
