The Brain frame of the Pope?

Charlotte Therese: "My thought is developed mainly through writing; so for me it was really a burden, a school of patience, not to be able to write for six weeks.”'"

According to Cahrlotte Therese the Pope has uttered the above. It seems they have him on a "brain frame" where he can only think when he writes. I guess it is because they want to get all his thoughts on paper?
