I want to note that I’m going to be asking about physical/learning/developmental disabilities and conditions, as well as autism, and I hope I’ve been as respectful as possible but if I’m getting anything wrong please let me know. I’m here to learn, after all. The character in question is an eleven-year-old boy. For the sake of his character and the plot as a whole, he needs to be unable to communicate via spoken, signed, or written language. I know that there are some conditions which affect both ability to speak and fine motor function, but I can’t find enough information on any of them. I want to possibly write him as autistic, which is something I do have a decent knowledge of, but I don’t know if it’s possible or likely that this would affect his ability to sign/write. As another note, I do still want him to be able to walk, with or without assistive devices. As another note, simple answers are fine and very much appreciated, and I’ll use them as a jumping off point, but if you could expand at all that would be wonderful. How would this particular condition affect his life outside of communication? The protagonist becomes his main aide, what would she need to assist him with?
