In her video, the Ant-Man star shared, "I’m entering into this new year, the Year of the Horse, with some bad news about my concussion. A lot of you asked how I’m doing. A lot of you have inquired about the brain scans that you heard I got. And the results came back from the scans.”The 46-year-old actress added, "So I do have brain damage from the TBI and possibly other factors going on. But now my job is to get to the bottom of that with doctors and then embark on the hard work of fixing it, which I don’t look forward to because I feel like hard work is all I do. But that’s okay. 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."

Now that she has some answers, the actress stated that she feels “extraordinarily grateful” and “blessed.” Michelle Pfeiffer, who co-stars as her mother in the Marvel films, added a red heart emoji and posted, "You are a warrior. Nothing-not even this will defeat you my friend."
