Here's a guy whose personality was radically altered by a stroke. It turned him into an appearance-obsessed QUEER.

The counter-argument that some of you people have used over and over against the suggestion that Steele's personality may have been altered from the mini-strokes accompanying his cardiac trauma and surgery is that
he still speaks clearly and seems lucid and you can't believe that a stroke could alter Steele's personality without also causing obvious cognitive impairment.
I heard Chris Birch in an interview on BBC Radio 4. He doesn't seem to have any more cognitive impairment than Steele.
Here's a video.
