My 83 year old mother has been suffering from “Trump derangement syndrome”. She gets extremely agitated and hostile whenever any Trump related news comes on. She’s also forgetful and grasps for words, much like Brandon. There is a history of Alzheimer’s in both sides of my family. Compounded by diabetes. I can tell that her mind is worse, when she doesn’t manage her blood sugar well.
Hallucinations can also be a sign of Parkinson’s. Does your mom have tremors?
She must be perpetually agitated then as the media brings Trump into almost all stories.
