Pure Word Deafness
Auditory verbal agnosia, also known as Pure Word Deafness, is caused by bilateral damage to the posterior superior temporal lobes or disruption of connections between these areas. It exhibits itself as inability to comprehend the meaning of speech, but (in most cases) still being able to hear, speak, read, and write. Individuals that exhibit pure word deafness are usually also able to comprehend non-verbal sounds. Sometimes this agnosia is preceded by complete cortical deafness of varying duration, however this is not always the case. Researchers have documented that in most patients exhibiting auditory verbal agnosia the differentiation of consonants suffers more than that of vowels, but as with most neurological disorders there is variation among patients.

Famous quotes containing the words pure, word and/or deafness:
“We are born with luck
which is to say with gold in our mouth.
As new and smooth as a grape,
as pure as a pond in Alaska,
as good as the stem of a green bean
we are born and that ought to be enough....”
—Anne Sexton (1928–1974)
“Reason sits firm and holds the reins, and she will not let the feelings burst away and hurry her to wild chasms. The passions may rage furiously, like true heathens, as they are; and the desires may imagine all sorts of vain things: but judgement shall still have the last word in every argument, and the casting vote in every decision.”
—Charlotte Brontë (1816–1855)
“By deafness one gains in one respect more than one loses; one misses more nonsense than sense.”
—Horace Walpole (1717–1797)
