Say someone experiences a traumatic brain injury from a fall and goes into a coma. I'm wondering what doctors in a modern hospital would be able to detect while the patient is in a coma and what they could not detect until the patient came out of the coma.
While the patient is in a coma, could doctors determine if the patient...
has had a stroke?
will suffer communication problems?
has paralysis in the extremities?
has deafness in one of the ears?
has partial blindness or loss of vision acuity?
I have found information about the effects of traumatic brain injury but not at what point the effects can be detected.
