Turf Issues:

At the hospital where I work, there is an active rehabilitation unit as well as an army of speech pathologists.  
The standard of care in the hospital is that if there are cognitive issues, it is the SLPs, and not the neuropsychologist, 
who are automatically consulted.  (I assume that this is in part because they have been around for a much longer period of 
time and neuropsychology has only been there for about 2 years).  Their consultations involve not just speech issues or 
swallowing, but all things cognitive.  They are brought in for all stroke and head injury patients, whether on the 
rehabilitation unit or not.  The nurses all call them automatically.  Today, I read a report from an SLP today stating 
that the patient had deficits in complex problem solving and that his impulsiveness rendered him unable to care for himself. 
So, some questions:
1) For those of you who successfully navigate these waters, what have you found beneficial in terms of working side by side 
with speech pathologists.?
2) What recommendations do you have for demonstrating the uniqueness of neuropsychology, both to the SLPs and to the docs and 
administrators?  (Of course, the next, perhaps more theoretical, question is "are we unique"?) 
3)  Is it legal for an SLP to comment regarding a person's ability to care for him or herself?  I assumed this was the 
province of MDs,DOs, and PhDs. 
4) When you find that they are using the same tests that you use, how have you addressed that with them?
Any thoughts on this would be appreciated.
