My Brother is Autistic

Overall this is really great for its target audience of siblings (or other children who have relations to) an autistic kiddo.

I didn't love the second half of this sentence: “Autism can't be cured, and that's why everybody in the family has to learn to share the problem.”
First, yay for saying that autism can't be cured, thank you. Second, the word ‘problem' is, well, problematic; I think ‘challenge' would have been less problematic. The word problem calls to mind the phrase ‘problem child' and the concept that problems (eg math problem) have solutions, but the first half of the sentence states that autism doesn't have a cure so then what's the solution?
