I have a schizophrenic man who has taken up residence in my back yard. I make sure he is fed and bathed on a regular basis.
I took him to the local hospital (in Bani) and the doctor in the emergency room made it very clear that this was not the United States and that I could not just drop him off at the hospital and expect him to be treated. (This was after one of the nurses gave me the dirtiest look and told me to go over to the other side of the room and wait for the doctor. I was reminded of the nurse in One Flew Over the Cuckoo's Nest, except that the nurse in the movie was far more compassionate than the nurse at the hospital.) I did insist that something be done so that he would calm down. He was given a sedative. We got an appointment for him to see the psychiatrist, but of course, on the appointed day, the doctor changed her schedule from morning to afternoon, and he could not be seen.
I checked on mental health institutions in the country. Padre Billini Hospital in the capital takes patients, but the reports I read said that the conditions are not good at all.
On a positive note, my "tenant" is making significant progress and is no longer ranting at thin air. The best therapy is allowing him to hug one of my dogs. And the folks in the neighborhood have started to send clean clothes, shoes, and food for him.
Next step is to contact his family and explain to them how best to help him so that he can return home to live with them. Many families do not know what to do, and from my very limited experience, the medical community is not helpful at all if one does not have financial resources.
