: My brother who fell down from a running train and suffered a TBI
and was on coma for one Month. Currently he has recovered
from coma but could not hear. He says there is a continuous
loud noise in both the ears. He could talk but pronounciation
is not up to the mark though it is improving after speech therapy.
Latest MRI scan shows the presence of a concussion.
Initially the MRI done in the first week
after the accident showed two concussions in which one has vanished.
Last few days he says that the noise in the right ear
has reduced significantly but still he is not able to hear
properly.
He could hear sounds of high frequency - like sound from a telephone bell.
Doctors suspect Agnosia/pure word deafness.
Dear Dr. V.K., Auditory Agnosia's can occour in several forms-inability to recognize sounds, musical notes and words-and can occour seperately or in combination. Word deafness (Auditory Verbal Agnosia) is the essential element in Wernicke's(Expresive) aphasia. It can occour seperately, without the other features of Wernicke's aphasia. In essence the left temporal lobe fails in its function of decoding the acoustic signals of speech and converting them into recognizable expressions. As a general rule, aphasias may take one or more years to completely resolve (if they do) because of the complexity of the mechanism involved. This rule may also apply to agnosia's. You may wish to discuss this issue further with your brother's neurologist and speech therapist about based on the TBI he suffered and their clinical experience with similar patients, what do thet expect long term. With the exception of speech therapy, no other therapies/treatments are known except the tincture of time. "This information is provided

Audiometry shows normal hearing in both ears - normal waveforms-
Latency in left ear (LE) prolonged compared to right ear (RE).
IpL prolonged between wave III and V in LE when compared to
RE.
It is three months since he met with the accident.
Please advice on any treatement known for this disorder
and also on chances of recovery.
