Mary may be exhibiting problems associated with Wernicke's area. 
People who have problems related to Broca's area also exhibit speech problems, however, when it comes to them, they can easily comprehend everything, but have a hard time trying to produce speech. On the other hand, patients with problems related to Wernicke's area don't have any problems speaking but their choice of words sounds nonsensical to everyone else but themselves.
