My grandmother has become very hostile and I'm afraid to even try to bring her to a doctor, is there anything I can do?

We have been living with my grandmother for several years now. She had moved to Florida and down there her health began to deteriorate. We brought her home for care and she began to get better, however there are some key things wrong with her. #1 Loss of memory (squirrels money away and forgets where. She also gives it away randomly and forgets then tries to do so again. She also forgets where things come from, who paid/pays for them, mixes up houses where things have been done. Frequently forgets to take medication.) #2 Delusions (Believes my family is trying to steal her house, that we are "against" her.) #3 Severe aggression ( Has put super glue in doors, said vile horrible things, cut random cables to electricity and T.V. / internet, continuously demanding we leave.) I would take her to a doctor myself, but she is very hostile and I have no idea what to do. Is there anything I can do? At this point we are on the verge of abandoning her to the situation. She is also destroying things in the house in an attempt to get us to leave.
