In a video announcement, Pat Summitt made the shocking disclosure that she's been diagnosed with dementia at a mere 59 years old. The Hall of Fame Coach said she started to notice strange behaviors last season like behaving "erratically" and second-guessing her decisions on the basketball court. It is rare that someone under 60 be diagnosed with early-onset dementia, and even rarer that people of that age display symptoms. Currently, Summitt is taking medications and working on puzzles to keep her brain sharp, and the basketball legend will return and coach another season for the Lady Vols with the help of her assistants.
