Not every disability can be seen from the outside. This topic introduces conditions that affect cognition, emotion and how people process the world, including autism spectrum disorder, learning disabilities like dyslexia, and mental health conditions such as depression, anxiety and bipolar disorder. Learners understand that people with invisible disabilities often face skepticism or lack of support simply because their condition is not visible. The key message is that true inclusion cannot stop at physical infrastructure like ramps and railings, it has to include understanding of what cannot be seen too.
