Useful takeaways from this story.

Mary Trump, who is a clinical psychologist, sees similarities between Donald Trump’s current behavior and her grandfather Fred Trump’s Alzheimer’s symptoms.

She cites examples such as disorientation about time and place, rambling public remarks, and increasing impulsivity and cruelty.

Mary contrasts Fred Trump’s softening under Alzheimer’s with what she describes as Donald Trump becoming more belligerent and prone to lashing out.

The useful part

Now Trump's gay niece, Mary Trump, is adding to that speculation by noting that she sees similarities between the president and her grandfather's mental decline. In her post, she said that the news that her uncle was mentally deteriorating had been plain for anyone to see. "What is obvious to anybody with eyes is that Donald continues to demonstrate the fact that he is psychologically, emotionally, cognitively, and physically in decline," Mary Trump wrote.

How it works

  • The Dutch study mirrors a similar study showing declining support for LGBTQ+ people in the US.
  • "He's openly bragging about how he set a child predator free after 2 months?
  • I'm beginning to see that look in Donald's eyes sometimes." But Mary Trump sees something much more alarming with her uncle.
  • While she knew her grandfather as a "straight up sociopath, a cutthroat businessman, and a cold, unaffectionate father and grandfather," under Alzheimer's he seemed to get softer and more caring.
  • "I would argue that he is getting more cruel and more belligerent as he becomes more out of control.

What to take from it

She acknowledges that her grandfather's deterioration took place in his house when he was no longer making decision that had an impact on others. His impulse control is eroding at an alarming rate." And that raises the biggest concern at all. "Donald is President of the United States." "His decisions have a serious, deleterious, and terrifying impact on all of us," she writes.

Example or evidence

  • His fears, grievances, obsessions, and insecurities become public policy.
  • Marcy Kaptur's anti-trans ads Democratic groups are urging her to change course.
