My Grandfather was diagnosed with LBD, I live with my grandparents. All started about 3 years ago, he would wake up during the night almost every hour accusing my grandmother of doing stuff to him, so she started sleeping alone. Now, she has a device to make his bed shake and give him shocks to his feet, I guess he really feels this things due to his illness but he is very persistent with this story, he is very agitated, yells and his eyes are wide open when he has his episodes, he wants her to stop with this but no matter what I do, he is 100% convinced. Since he doesn't have anything against me, I try to be a mediator but it's slowly getting to me and my grandmother loses her calm by being accused of that and other things, such as doing drugs.
This is getting to be a daily issue, it wasn't so frequent in the beginning. Is this constant aggressive behaviour common in LBD patients? Are they usually this persistent with this confabulations? Any advice on how to deal with him?
