The appropriate specialists to identify an aphasia are the psychologists, psychiatrists and logopedas, these last ones very trained for the diagnosis. The diagnosis is based in two big aspects: The data that he/she offers the clinical history. and The results in the application of the test neuropsicológico of Luria value the expressive language (external), codifier that measures the following spheres: spontaneous, automatic language, repetitive language, nominative language, narrative language, as well as the language decoder that is explored with the discrimination of phonemes, 

stability of the nominative functions, the-structure of the meanings 

(generalizations), the understanding of the grammatical structure and the predicative aspect of the language. The presage of the rehabilitation of the aphasic patients depends on those  endogenous factors of the lesion (type, size, localization, etiology) and those of the one  patient (age, sex, cultural, social, family level, occupation) and of those  exogenous that depend of the treatment like such, the assumed method and the 

cooperation of the patient and family.

Dear Carmen,

Thank you very much for your valuable response.

You are welcome!!!!

What do you mean with the afacia of Boston Orion?

I have only one example of a patient on whom I was doing a mental status exam (standard one) who had come with a diagnosis of catatonia.  Using the MSE, she was clearly _not_ catatonic because she was activity engaged in the interview and showed lots of affect, neither of which a catatonic person does.  She was able to understand questions and tried hard to respond to them.  She simply was unable to verbally express herself.  It turned out on further work up (which took longer than it should have) that she'd had a stroke which had caused expressive aphasia.  On the MSE she was intact except for lacking the ability to express herself verbally.  I agree that aphasia is not cognitive. This patient acted like she knew what she wanted to say, she simply couldn't say it, which is a motor deficit.

There is no CT scan or MRI?  Asked to see the neurologist and suggested for the same.    If you have any neuro-psychological profile related with aphasia, please provide me the same. 

Hello again. Sailaja looks, the aphasias are considered of several types. Aphasia motorboat, sensorial aphasia and global aphasia. The first one (motorboat, in the area of Drill) it is observed in the patients that understand that that your you tell them but they cannot be expressed well and the second (sensorial, area of Wernicke) it is the opposite, they can be expressed better but they don't understand you well, he/she takes them a lot of time. In all the cases it is product of a cerebral lesion due to a cerebrovascular accident or a traumatism craneoencefálico where the expression, the understanding, the reading and the writing are affected. In these case it would not be of more to explore the other cognitive processes but you will not necessarily find related affectations, rather they can be damaged previously or product of another event that has damaged other parts of the brain. I wait to have been able to help you.

Did the person have a head injury, stroke or history of heavy drinking, cocaine or other drug use?

I am a student, so I don't have a lot of experience, but I used the Halstead-Reitan Aphasia Screening Test, which was super quick to administer and easy. 

It really depends on the clinical environment you work in. I'm working in a Neuropsychiatric rehabilitation facility and we have a set of exams, but they might differ from the ones performed in, for example, Neurology departments. I suggest you check with the facility you are working in, and what their usual evaluation tests are. In our facility we usually have a Neuropsychiatrist evaluate them first and then our team works with them.
