From Newsday this past weekend, on Art Shamsky's new 1969 book (co-authored with Erik Sherman): Shamsky wrote that Seaver suffers from short-term memory loss, which Seaver told him can be traced to Lyme disease, a bacterial infection transmitted by ticks, contracted in 1991 when he lived in Greenwich, Connecticut. "Hey, man, once you've got it, you've got it forever," Seaver said to Shamsky. Bud Harrelson (when he, Jerry Koosman and Ron Swoboda joined Art on a pilgrimage to Seaver's home in 2017 -- before Buddy's diagnosis of Alzheimer's became public) told Shamsky, "He can forget things that happened just a few minutes before. And he repeats himself a lot. But when he gets his rest, he still has a lot of energy." The Newsday article never used the word dementia, but somebody with knowledge of the situation told me last year that's what was going on. I was hoping it was hyperbole.
