LAST approaches autism from a neurodiversity perspective. Neurodiversity is simply the natural variation of human brains and minds. The neurodiversity paradigm is a way of thinking that sees different minds as a natural and valuable aspect of human diversity.
This way of thinking emphasizes the social power structures that exist around neurological differences, and the ways in which social barriers and inequalities put people with disabilities at a disadvantage. This perspective does not deny that aspects of various neurological differences can be unpleasant, and can include specific impairments. However, the neurodiversity paradigm looks at how society is organized in ways that make some things less accessible for certian people.
Many of the barriers we face related to disability can be removed with appropriate accommodation, and universal design.
