In a heartfelt revelation that has shocked fans worldwide, “Lost” and Marvel actress Evangeline Lilly has opened up about suffering brain damage and cognitive impairment after a traumatic accident in Hawaii last year.
The 46-year-old star shared the news in an emotional Instagram video posted earlier this year, detailing how a fainting spell led to a severe fall on a beach.
While enjoying time in Hawaii in May 2025, Lilly suddenly fainted and fell face-first onto a large boulder, sustaining a traumatic brain injury (TBI) that required stitches for her facial wounds.
Initial hospital tests after the incident came back normal, but lingering symptoms such as cognitive fog and memory issues prompted further medical evaluations months later.
Lilly has a history of unexplained fainting and blackout spells dating back to her childhood, which doctors have yet to fully diagnose and which may have contributed to the fall.
Recent brain scans revealed the devastating impact: almost every area of her brain is now functioning at a decreased capacity, confirming lasting damage from the TBI.
The actress described experiencing significant cognitive decline, including memory lapses, mental fatigue, and difficulties processing information that have affected her daily life.
“Verdict’s in… I do have brain damage from my TBI.
Comforting to know my cognitive decline isn’t just peri-menopause, discomforting to know what an uphill battle it will be to try to reverse the deficiencies,” Lilly wrote in her Instagram post.
Fans and fellow celebrities have flooded social media with messages of support, praising her transparency and resilience amid the challenges of recovery.
Known for her role as Kate Austen on the hit series “Lost” and as the Wasp in the “Ant-Man” films, Lilly’s revelation has highlighted the often-hidden effects of head injuries in everyday life.
Despite the uphill battle, the actress remains optimistic about treatment and is focusing on rest and recovery as she navigates this new chapter in her life and career.
