I'm a 1st year medical student, and I just learned today about doing a mini-mental status exam...on a human, anyway. It brought to mind a story a friend of mine told me: his family dog, whom they'd had for a couple of years at least, ate a battery and they took it to the vet. The vet took them aside and told them that the dog was mentally ******ed, which came as a complete surprise to the family. Unfortunately, I don't have much details. So I don't know if the vet was basing it on the fact that the dog decided to eat a battery...or if vets routinely do some kind of mental exam? I guess it would be easy to see severe mental ******ation in an animal, but how do you test a dog, or whatever, that convinced the family it was normal? And - would you tell someone that their beloved pet is mentally ******ed, if they've been contently living with their pet for years with no problems?
