This chapter critically looks at this relation between mental health and disability which is very intricate and sometimes controversial. It makes mental health conditions, also known as psychosocial disabilities, squarely within the area of disability studies beyond traditional and medically dominant approaches. The chapter starts with the discussion of theoretical change of the medical model to the social and biopsychosocial models and the criticism that is transformative as provided by the Mad Studies movement. It examines the lived experience of psychosocial disability and deals with the problem of identity, stigma, and the politics of labeling. Much attention is devoted to intersectionality, the high co-occurrence of mental distress among the physically, sensory, and intellectually challenged, and neurodiversity paradigm. This chapter is an organized account of the systemic obstacles such as stigma, poverty, and coercive legal practices that manifest the disability multiplied. It in turn promotes inclusive, rights-based solutions including person-centered care, peer support, trauma-informed practices, and complete adherence to the UN Convention on the Rights of Persons with Disabilities (CRPD). Lastly, the chapter gives future directions, which include the participation of research, the integration of ethical technologies, and the decolonization of mental health practices. The general thesis is that an inclusive disability studies has to make mental health central to the latter, and not peripheral, but rather at its heart.
