My dad has psp. He chokes a lot. A lot. He seems so extra ill all the time at the moment.... stuff like always being too hot, being so tired all the time, feeling dizzy and weak. I'm worried he might have some kind of infection from aspiration of food particles. What would be the symptoms of this be? He has a mouth full of rotten teeth ( he has always refused to see a dentist his whole life long ) so always has bad breath so how can we tell if he has a chest infection? I'm concerned the teeth themselves would be an infection risk? I'm unsure he even has the motor control to brush his teeth now if he were so inclined.
