Evangeline Lilly, 46, has revealed she has brain damage following a concussion she suffered in May. The Canadian actor, famous for roles in Lost and Marvel films, fainted and hit her head on a boulder. She shared a video on Instagram explaining that a recent brain scan showed "almost every area in my brain is functioning at a decreased capacity." Lilly said, "So I do have brain damage from the TBI and possibly other factors going on." She added that her next step is to work with doctors to understand and fix the damage, although she does not look forward to the hard work. Lilly said, "My cognitive decline since I smashed my face open has helped me to slow down and helped me to have a more restful finish to my 2025." In the caption, she wrote it was "comforting to know my cognitive decline isn’t just perimenopause, discomforting to know what an uphill battle it will be to try to reverse the deficiencies." Her Marvel costar Michelle Pfeiffer encouraged her by writing, "You are a warrior. Nothing – not even this will defeat you my friend." After the accident, Lilly shared photos of her injured face and described the fainting spell on Substack. She wrote, "My partner says that when I black out, I look like I die. He gets very afraid." She has had fainting spells since childhood but believes now her body reaches a limit and "she ‘leaves the building,’ so to speak." Despite the injury, she feels grateful, saying, "I feel so grateful that I blacked out. I needed the reset." Lilly has paused acting for three years. Her last role was the Wasp in the 2023 Marvel film Ant-Man and the Wasp: Quantamania. In June, she told Variety she is "not actively pursuing any work in the industry" and is focusing on humanitarian work and writing.
