These are great images, but should not necessarily be surprising. CP may involve some physical uncoordination, but with full mental acuity. If anything, this this makes for frustration that is hard to bear for anyone, patient or caretaker alike.
Whatever may be the physical or mental limitations of a person you may be caring for, I think the best you can do is to seek out the best your charge can do, and to cultivate that. You, and he or she, may be surprised.
