Olympic snowboarder Chloe Kim has spoken out about a personal health matter, saying she was found to have ADHD after years of struggling without answers. She described the diagnosis as something that changed everything for her.

Kim holds three Olympic medals and competed at the highest level of her sport during a period when her condition was still going unrecognized. She did not specify when exactly she received the diagnosis.

Kim is dating NFL player Myles Garrett. Many fans were caught off guard by the announcement, since elite athletes are generally assumed to have strong mental focus. Her decision to speak publicly has drawn a strong response from supporters.
