It started with a routine scan. Well, "routine" if you’re a billionaire who gets full-body MRIs for fun. In late 2025, Kim Kardashian dropped a bombshell during the Season 7 premiere of The Kardashians that stopped everyone in their tracks. She told her family—and millions of viewers—that doctors found a "little aneurysm" in her brain.
Kourtney’s reaction was a simple, stunned "Whoa." Honestly? Same.
When a celebrity as famous as Kim mentions a brain aneurysm, the internet does what it does best: it panics. People immediately started searching for symptoms, causes, and whether they needed to drop thousands of dollars on the same high-tech scans she uses. But behind the dramatic music and the emotional phone calls to Kris Jenner, there is a lot of medical nuance that didn't quite make it into the 30-second teaser clips.
The Discovery: Not Your Average Doctor's Visit
Kim didn't find this because she had a splitting headache. She found it because she’s a vocal advocate for Prenuvo, a company that offers elective, $2,500 full-body MRI scans. These scans are designed to catch things before they become problems. In Kim’s case, it worked.
She later confirmed on Good Morning America that after the initial Prenuvo finding, she went to Cedars-Sinai for more intensive testing with a specialized neurovascular team.
"Health is wealth," she told Robin Roberts. It’s a catchy line, but for most people, a "routine" brain MRI isn't something their insurance covers unless there's a specific reason. Kim’s diagnosis is what doctors call an incidental finding. You’re looking for one thing, and you stumble upon another.
What exactly is a brain aneurysm?
Think of your arteries like a garden hose. Over time, or due to genetics, a specific spot on the hose wall might get thin or weak. Under the pressure of flowing water—or in this case, blood—that weak spot starts to bulge out like a tiny balloon. That’s an aneurysm.

Most of the time, they just sit there. They don’t pop. They don’t cause pain.
But if they do rupture? That’s a hemorrhagic stroke. It’s a "call 911 immediately" situation. Dr. Adam Arthur, a neurosurgeon, explained that roughly 1 in 50 people are walking around with one of these right now and have no clue.
Kim Kardashian Brain Aneurysm: Is Stress Really the Culprit?
In the show, Kim was visibly emotional. She mentioned that her doctors suggested the cause was "just stress." She pointed to the "next level" pressure of the California bar exam, her high-profile divorce from Kanye West, and the constant weight of running multiple empires while raising four kids.
"People think I have the luxury of walking away," she said. It’s a heavy sentiment. But medically speaking, can stress actually cause a hole or a bulge in your brain?
Kinda, but it's complicated.
The Nuance of the Stress Connection:

- Direct Cause: There is no scientific evidence that being stressed out magically creates an aneurysm out of thin air.
- The Blood Pressure Factor: Chronic stress releases cortisol and adrenaline. These spike your blood pressure. High blood pressure is the #1 enemy of your arteries. It pounds against those vessel walls until they weaken.
- The Trigger: While stress might not create the aneurysm, a sudden surge in blood pressure (from intense anger or physical exertion) can sometimes trigger a rupture in an existing one.
So, while Kim’s doctors might have used "stress" as a shorthand, it’s more likely that the physical toll of that stress on her cardiovascular system was the real concern.
The "Holes" in the Story (and the Brain)
Things got even weirder in later episodes. Kim visited Dr. Daniel Amen, a celebrity psychiatrist who uses SPECT scans (Single-Photon Emission Computed Tomography). He told her she had "holes" in her brain, specifically in the frontal lobe, which he linked to low activity and—you guessed it—stress.
This is where you have to be careful.
Many mainstream neuroscientists are skeptical of SPECT scans for this purpose. Sarah Hellewell, a brain health researcher, noted that these "holes" aren't physical gaps in the brain tissue. They are just areas where blood flow is lower at the moment of the scan. Calling them "holes" is a bit of a dramatic flair that makes for great TV but can be misleading for patients.
What Most People Get Wrong About This Diagnosis
The biggest misconception is that an aneurysm is a ticking time bomb that will eventually explode.
That’s just not true.

Most small, unruptured aneurysms have an annual rupture rate of less than 1%. Because of this, surgeons often choose "watchful waiting." They’ll scan you every year to see if it’s growing. If it stays small, they leave it alone. The risks of brain surgery—even minimally invasive ones like coiling or stenting—often outweigh the risk of the aneurysm actually bursting.
Kim mentioned she consulted with Dr. Keith Black, a world-renowned neurosurgeon. While she hasn't shared her specific treatment plan, her "everything works out" comment suggests she’s in the monitoring phase rather than recovering from a major operation.
Key Risk Factors: Who Is Actually at Risk?
If you're worried because of Kim's story, it helps to look at the hard data. This isn't just a "celebrity" problem, but it hits certain groups harder.
- Gender: Women are significantly more likely to develop brain aneurysms than men. Some researchers think this is linked to estrogen levels, especially after menopause when blood vessels lose some flexibility.
- Genetics: If you have two "first-degree" relatives (parents or siblings) who have had one, your risk jumps to about 11%.
- Lifestyle: Smoking and heavy alcohol use are massive risk factors. They degrade the quality of your arterial walls faster than almost anything else.
- Age: They are most commonly found in people aged 40 to 60. Kim, at 45, fits right into this demographic.
Actionable Insights: What Should You Do?
If Kim's news has you spiraling about your own brain health, take a breath. Unless you have a strong family history or are experiencing specific symptoms, you probably don't need a $2,500 scan.
When to actually worry:
If an aneurysm is large and pressing on a nerve, you might feel pain behind your eye, see double, or feel numbness on one side of your face. If it ruptures, you will know. People describe it as a "thunderclap headache"—the worst pain of their entire life, appearing in seconds. If that happens, you don't call your primary care doctor; you go to the ER.
Steps you can take now:
- Manage your "Numbers": Get your blood pressure checked. If it’s high, treat it. This is the single best thing you can do for your brain.
- Quit Smoking: It sounds cliché, but nicotine is a primary driver of vessel weakness.
- Stress Management: Even if it didn't "cause" the aneurysm, managing stress prevents the blood pressure spikes that lead to complications.
- Screening: Only seek out specialized imaging if you have the "two-relative" rule or persistent, unexplained neurological symptoms.
Kim Kardashian’s brain aneurysm revelation is a reminder that even with all the money in the world, the human body is fragile. It’s brought a rare condition into the spotlight, but the lesson isn't to live in fear. It’s to keep your blood pressure in check and listen to your body when it tells you something is genuinely wrong.
Next Steps for Your Health: Start by tracking your blood pressure at home for one week. If your resting numbers are consistently above 130/80, schedule a check-up with your doctor to discuss long-term vascular health. This simple step is more effective for aneurysm prevention than any one-off celebrity-endorsed scan.
