Question 9 is much more about the physical issues that a claimant would have with communication, the obvious examples would be someone one who is deaf or mute, brain damage or a severe learning disability may also count.
The Descriptor does not explicitly ignore mental health issues but I think you would need to present a very convincing argument to score, especially given the definitions for Basic and Complex information.
