It's certainly interesting. I'm particularly curious about the effects of the multiple confusions:

US had three concussions as an adult, caused by car accidents and from falling on ice. The most recent and severe incident occurred in January 2018, resulting in classic symptoms of light sensitivity and concentration difficulty. US feels she is a “different person,” with increased anger and anxiety. She requires additional time to process information in some problem-solving situations, although she has always seen herself as a poor test taker.

Some of the conclusions seemed a stretch for a single sample. I'm much more curious about more extensive studies with many more subjects.

Gotta say as someone who experienced traumatic brain injury I also feel like I'm a different person, and not as bright as I used to be. The doctors estimate I lost somewhere on the order of 15-20% of whatever that was.

Exactly, there's a lot of different factors that can affect cognition.
