Hello, my grandmother (80) has always been manipulative and capricious, when something doesn't go her way, she would make a big scene, stop talking to us, stay in her bed for days... but lately it is getting worse. She seems to be filled with resentment and anger towards everything and everyone. We think that her character is probably worsened by some sort of dementia. She has become abusive, especially with my granfather (88), but also to her kids (60, 58, 57, 56). She went to see a psychiatrist but told him a beautiful story about everything being perfect in life just being a bit down. She does not allow anyone to go with her and she refuses to get any other sort of help. She is tearing our family apart and nobody knows what to do. We don't know how to respond to her attacks (obviously not respond in the same way, but should we try to make her see or just ignore?), what do we do when she is being abusive to my grandfather (stop her? confront her? ignore it?)... we really are lost and would love to have some advice.
