Mom doesn't speak English and is illiterate in her own language. Think she is depressed and may have other mental health issues (maybe even dementia) but can't get regular neurologist or staff pysch to evaluate her because she doesn't understand English nor is she literate so they are telling me they cannot assess her. HELP please! She keeps talking about wanting to die.
This is just a guess but is there an association of people of her nationality? If so, perhaps you could contact them and ask if they know of any doctors who speak her language. If there are enough people for a group to be affiliated, then they must have some doctors, and perhaps some know of doctors who could communicate with your mother in her native language.
You write that she expresses a death wish; so I assume you understand what she's saying in her own language? Couldn't you interpret for the doctors?
Bloodwork will tell the MD how well kidneys and liver are working, not what the patient says. Please try to accept what they tell you.
