Eilish, who was diagnosed at the age of 11 with the neurological disorder, which can cause uncontrollable and unwanted vocalization and/or repetitive movements, said people sometimes misunderstand what is happening.
“The most common way that people react is they laugh because they think I’m trying to be funny,” she said. “And I’m always left incredibly offended by that.”
The 20-year-old Grammy winner said other artists have shared with her that they also have Tourette’s, but said she was “not gonna out them because they don’t wanna talk about it.”
She said that while some of her tics have subsided, she still has some subtle ones.
“These are things you would never notice if you’re just having a conversation with me,” Eilish said. “But for me they’re very exhausting.”
Eilish said she’s happy to talk about it as it’s all “interesting” to her. She also said she doesn’t experience tics while she’s performing.
“When I’m moving around I’m not even ticking at all,” she said.
