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:
“Who knows whither the clouds have fled?
In the unscarred heaven they leave no wake,
And the eyes forget the tears they have shed,
The heart forgets its sorrow and ache;
The soul partakes the season’s youth,
And the sulphurous rifts of passion and woe
Lie deep ‘neath a silence pure and smooth,
Like burnt-out craters healed with snow.”
—James Russell Lowell (1819–1891)
“From the moment a child begins to speak, he is taught to respect the word; he is taught how to use the word and how not to use it. The word is all-powerful, because it can build a man up, but it can also tear him down. That’s how powerful it is. So a child is taught to use words tenderly and never against anyone; a child is told never to take anyone’s name or reputation in vain.”
—Henry Old Coyote (20th century)
“By deafness one gains in one respect more than one loses; one misses more nonsense than sense.”
—Horace Walpole (1717–1797)
