Sorry but only they can tell you anything about how and why they are diagnosing you the way they are..

if you feel they are not on the same page as you are, you will need to talk to them about it and let them know you do not understand. they will communicate with you in other corms of communication that you will be able to understand...its ADA laws. if they dont they can lose their job and their credentials.

can your lack of understanding be because of TBI (traumatic brain injury) ? anything is possible, but Im guessing you would know by now if your problem was because of TBI...heres why...

the part of the brain that is responsible for understanding what others tell you, is also the part of the brain that is responsible for things like talking walking, logic, reasoning, hearing, vision, writing, reading and comprehending what one is reading, doing math and other academics, along with things like taste, emotions, balance, co ordination and other uses of the muscles....

also what I posted before works for TBI too.... just tell your treatment providers you dont understand them and they have to by law supply the information in written, and other forms of communication.

if you feel your treatment providers are speaking too fast for you to understand you will need to be the one to tell them to slow down and that you dont understand. they will by law have to supply you the information in other forms of communication.
