I think his problem is fluent aphasia. Here’s the definition from Wikipedia:
Speech is preserved, but language content is incorrect. This may vary from the insertion of a few incorrect or nonexistent words to a profuse outpouring of jargon. Grammar, syntax, rate, intonation and stress are normal. Substitutions of one word for another (paraphasias, e.g. “telephone” for “television”) are common. Comprehension and repetition are poor.
Example:
“I called my mother on the television and did not understand the door. It was too breakfast, but they came from far to near. My mother is not too old for me to be young.”
Patients who recover from Wernicke’s aphasia report that, while aphasic, they found the speech of others to be unintelligible and, despite being cognizant of the fact that they were speaking, they could neither stop themselves nor understand their own words.[citation needed]
Patients also generally have no trouble purposefully reciting anything they have memorized. The ability to utter profanity is also left unaffected, however the patient typically has no control over it, and may not even understand their own profanity.
Interesting...considering that huge scar on Obama’s head...we of course, have no medical info on this moron, past or present.
