Pathological Demand Avoidance (PDA) is a term used to describe a profile of Autism Spectrum Disorder (ASD), characterized by extreme resistance to everyday demands and requests. Although it is commonly understood as a subtype of ASD, we are still in the early stages of our understanding of PDA and research is still in its infancy.

Neurodiversity, coined by sociologist Judy Singer, refers to the “limitless variability of human nervous systems on the planet”. Much like biodiversity in nature, which understands the multitude of varying species and organisms in our world, neurodiversity recognizes that people have different brains.
