My family member had a mental attack and had to be rushed into psychiatric hospital. After 2 weeks she was released from hospital and now takes haloperidol, olanzapine and other medicine.

She suddenly became slow, passive, nonemotical, sleepy, tired, she gained a lot of weight (she used to be slim), but the problem is that she keeps opening her mouth. When she talks/eats/yawns, she closes her mouth for a second but then immediately opens it again. She looks really stupid with that mouth & it makes me sad.

Otorhinolaryngology doctor didn't help, she said we should deal with that & that it is permanent, psychiatrist doesn't solve it either.

I wanna ask if you have any experience with that...is there a way of treatment? Does the medicine do it or her brain got damaged because of the illness?

Sorry for english
