A patient cannot understand anything said to him, though he can hear that speech is occurring and other sounds normally, but reads and writes without any difficulty at all. Before revealing the answer: is this agnostic alexia?
No, this is more consistent with pure word deafness than agnostic alexia. The disturbance here affects spoken language comprehension specifically, with reading and writing preserved, which is the reverse of agnostic alexia's pattern of affecting written rather than spoken language.
