Ariana Grande went on Instagram to share photos of her brain scanner, which she says shows post-traumatic stress disorder.
"Hilarious and terrifying", she subtitled, adding that it is "not a joke".
PTSD is an anxiety disorder that can occur in some people after witnessing or experiencing traumatic events. Charles B. Nemeroff, M.D., Ph.D., professor of psychiatry at the University of Texas at Austin, said that several studies have shown changes in the brains of patients with PTSD.
"There is no doubt that PTSD changes the way the brain reacts to emotional stimuli related to trauma and the like, but there is no brain imaging test to diagnose PTSD." he told CNN.
This is not the first time the singer has been open about her struggles since the suicide bombing that killed 22 people during her concert in Manchester, UK, in May 2017.
Grande said that she never thought she knew how to talk about the attack "without crying" in an interview with British Vogue in July 2018.
"I know these families and my fans, and everyone there has also experienced a lot," said Grande about the symptoms of PTSD. "I feel I should not even talk about my own experience – as if I do not even have to say anything."
The supporters of Grande have expressed concern over the 25 years on social media. Many urge him to move away from the spotlight to heal himself.
"I just hope that she will not overwork herself and no longer exhaust herself mentally / physically," one person wrote on Twitter.
"Honestly, she needs a break, a very long one, just to heal completely and assimilate everything that has happened to her," wrote another.
After seeing the answers to her brain scan message, the singer told a story on Instagram in which she said she was doing her best, even though her brain "looks like the world map ".
"I did not want to surprise anyone with my brain," she wrote on Instagram. "I love science and seeing the physical reality of what's going on there was incredible for me, and one day when I'm better healed, we can talk more about it."
