An interesting article on a faculty member who suddenly discovered he had epilepsy while beginning his faculty career. The "Working Life" column has a number of articles about disability and chronic illness, including many on mental health in academia.
Even if these numbers don't reflect the leaky pipeline (n=1! etc.), the lack of faculty representation at that social was disheartening.
(1) Either you don't think you have disabled students
(2) You don't care about supporting them
or (3) There aren't many/any disabled faculty
We (hopefully) celebrate inclusion of racial/ethnic minorities, women, queer folks, first generation folks, but rarely folks with disabilities.
