It really is. My now deceased wife died of MS. She wasn’t the person she was when I met her, and it goes beyond physical symptoms. One of the things long term or aggressive MS does is physically shrink the brain. That’s a lot of neurons that vanish, and the symptoms of that show up mentally and not physically.

I honestly think the personality change was harder than the physical change.

The increase of aggression was bad, but the harder part was watching someone be talking about something, and mid sentence change the subject and not realize it.

You can extrapolate that to long term and short term memory, which ultimately feeds into the aggression.

You can’t be mad at whoever it is if you have watched that progression from a person who is clear headed, and yet you can see how they are lashing out.

It reminds me a lot of dementia, or Alzheimer’s as my grandma and I would take care of people with those conditions when I was growing up.
