5 Celebrities Who Made Alarming Health Diagnoses Public in 2025

Chronic and deadly diseases do not pick favorites as many celebrities faced health problems in 2025.

From cancer diagnoses to neurological complications, here 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.

The 45-year-old reality TV star revealed on a November 2025 episode of “The Kardashians” that the doctor found “holes” in her brain stemming from a possible aneurysm.

“So what the holes mean is low activity,” Amen said in the episode. “The front part of the brain is less active than it should be. With the current functioning of the frontal lobes, it would be more difficult to control stress.”

“It could be the chronic stress you’ve been under, trying to think about taking boards in a couple of months and studying 10 hours a day, not to mention all the other things going on in your life,” he continued. “But we have to improve it.”

At the time of filming, Kardashian was preparing to take the California bar exam. He later revealed that he did not pass.

No. 2: Dave Coulier, cancer rediagnosis

“Three by Three” 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.

But in October, Coulier reported a second diagnosis of HPV-related oropharyngeal tongue cancer, apparently without warning signs.

“Going through chemotherapy and feeling that relief of, ‘Wow, it’s gone,’ and then getting a test that says, ‘Well, now you have another type of cancer’… it’s a shock to the system,” Coulier shared on “Today.”

The confirmed early-stage P16 carcinoma was “unrelated” to non-Hodgkin lymphoma and is likely related to the long-term presence of HPV, he added.

“They said it could come from having had an HPV virus up to 30 years ago,” he said. “Many people carry the HPV virus, but they said mine activated and turned into a carcinoma.”

“We found it early enough and it’s very treatable… It has 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 “dear family” and the chance to return to the set of HBO’s “Euphoria.”

The actor spoke about his developing condition on “Good Morning America,” telling host Diane Sawyer that he only has function in one arm.

He also shared that he is “very hopeful” and willing to do everything he can to combat the neurodegenerative disease.

“I don’t think this is the end of my story,” he said in the same interview. “And whether it is or not, I will carry that idea with me.”

Dane was later hospitalized during the night of the Emmy Awards in September, after an ALS-related fall led to “stitches in my head,” he told The Washington Post.

Dane’s ex-wife and caregiver, actress Rebecca Gayheart, wrote an essay that was recently published in The Cut, revealing that Dane has “24/7 nurses” and receives round-the-clock care.

No. 4: Billy Joel, normal pressure hydrocephalus

Billy Joel, 76, was diagnosed with a rare brain disease in May 2025, resulting in the cancellation of his scheduled concerts.

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

“This condition has been exacerbated by recent concerts, resulting in hearing, vision and balance problems,” reads an announcement on Joel’s website.

“Under his doctor’s instructions, Billy is receiving specific physical therapy and has been advised to refrain from performing during this recovery period.”

In July, Joel joined Bill Maher’s podcast “Club Random with Bill Maher,” during which he reported that he is “working on his health.”

“I feel good,” 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 continued. “They keep referring to what I have as a brain disorder, so it sounds a lot worse than what I feel.”

No. 5: Gordon Ramsay, skin cancer removal

In August, celebrity chef Gordan Ramsay revealed that he had basal cell carcinoma, a type of skin cancer, removed from his face.

Ramsay, 58, shared two photos on Instagram after the procedure, one showing a large bandage placed under her ear and the other showing a row of stitches.

“Please don’t forget your sunscreen this weekend,” he warned in the post. “I promise it’s not a wash! I would need a refund…”
