Chronic and fatal diseases do not choose favorites, as many celebrities faced health scares in 2025.
From cancer diagnoses to neurological complications, below are five celebrity health battles that stood out this year.
No. 1: Kim Kardashian, brain aneurysm
Kim Kardashian was diagnosed with a brain aneurysm after undergoing a brain scan with psychiatrist Dr. Daniel Amen of Amen Clinics.
KIM KARDASHIAN'S BRAIN ANEURYSM SCARE: DOCTORS REVEAL WARNING SIGNS TO NEVER IGNORE
The 45-year-old reality TV star revealed in a November 2025 episode of "The Kardashians" that the doctor found "holes" in her brain stemming from a potential aneurysm.

"So, what the holes mean is low activity," Amen said in the episode. "The front part of your brain is less active than it should be. With your frontal lobes as they work now, it would be harder to manage stress."
ERIC DANE VOWS TO 'FIGHT TO THE LAST BREATH' IN ONGOING ALS BATTLE
"It could be the chronic stress that you've been under, trying to think about taking the boards in a couple months and studying 10 hours a day, not to mention all the other things that go on in your life," he went on. "But we have to make it better."
At the time of filming, Kardashian was gearing up to take the California bar exam. She later revealed she did not pass.
No. 2: Dave Coulier, cancer re-diagnosis
"Full House" star Dave Coulier announced the return of cancer, just months after declaring he was cancer-free.
The comedian, 66, was diagnosed with stage 3 non-Hodgkin lymphoma in 2024. He then announced his recovery in March after six months of chemotherapy.

"To go through chemotherapy and feel that relief of ‘Whoa, it’s gone,’ and then to get a test that says, ‘Well, now you’ve got another kind of cancer’ ... it’s a shock to the system," Coulier shared on "Today."
The confirmed early-stage P16 carcinoma was "totally unrelated" to the non-Hodgkin’s lymphoma and is mostly likely linked to the presence of long-term HPV, he added.

"We found it early enough where it’s very treatable. ... It’s got a 90% curability rate."
No. 3: Eric Dane, ALS
"Grey’s Anatomy" alum Eric Dane has been battling ALS, also known as Lou Gehrig’s disease, this year.
Dane announced his diagnosis to People in April 2025, noting his gratitude for the support of his "loving family" and the ability to return to the set of HBO’s "Euphoria."

The five-time Grammy winner announced that he has normal pressure hydrocephalus, which occurs when cerebrospinal fluid builds up inside or around the brain.

"I feel fine," he said. "My balance sucks. It’s like being on a boat … It used to be called water on the brain. Now it’s called hydrocephalus — normal pressure hydrocephalus."
"I feel good," he went on. "They keep referring to what I have as a brain disorder, so it sounds a lot worse than what I’m feeling."
