Yep, and the combinations they can exist in, too: how physical disabilities affect frequency and treatment of mental health conditions (and vice versa: when I still had a job, it took me to an interesting seminar on diagnosing visual impairments in people with learning disabilities, which combination had never occurred to me; also via my ASD husband I've learned it's difficult to diagnose autism in blind people because some of the autistic presentation overlaps so much with blind people's difficulties and even coping strategies). The intersection of more than one kind of disability is really underappreciated, considering how common it is for a person to have/develop more than one facet of disability.
