Lauren Miller Rogen Reveals She Had Brain Aneurysm Removed: ‘I'm Truly Grateful’

Rogen said she decided to get a full body MRI five years ago “to take a deeper look at anything that... would affect my longevity"

Lauren Miller Rogen underwent treatment for a health scare last year.

The actress, comedian and wife of Seth Rogen, 42, revealed during her speech at the UCLA Department of Neurosurgery Visionary Ball in Beverly Hills on Wednesday night that like her grandmother and mother — who both suffered from dementia — she too has had her own challenges when it comes to her brain health.

Lauren, who was inspired to form the nonprofit Hilarity for Charity to raise money for dementia care, research, and education due to her family history, said she decided to get a full body MRI five years ago.

She noted that she made the decision “to take a deeper look at anything that could possibly be lurking inside me that would affect my longevity,” and the doctors were able to flag down a potential problem.

"They found, of course, this sort of aneurysm in my head,” Lauren shared. “So of course, this was terrifying information, and made me think of my great-grandmother, whose fate I certainly didn't want to mimic.”

“Fortunately, it was relatively small, and I did what the doctors recommended that I do, which is have annual MRIs [to] track the size,” she continued. “It remained small, until it didn't."

She said that doctors noticed the aneurysm started growing in her brain in the spring of 2022 — four years after they found it. Lauren revealed she immediately connected with UCLA neurosurgeon Dr. Dr. Geoffrey Colby, who had “answered every single question” that she had, and made her feel “comfortable” about the procedure ahead to remove the aneurysm.

She eventually underwent the procedure, and she's had several follow-up appointments since then to make sure her brain remains healthy.

“I'm truly endlessly grateful to Dr. Colby, his entire team, and the entire staff at UCLA who guided us through this scary experience that I'm truly grateful to have overcome,” Lauren said. She teasingly added, “I'm truly thankful that I won't be dying at this dinner table or any others anytime soon.”

In February, Lauren and Seth told PEOPLE that humor is "absolutely part of how we cope with things" after caring for Lauren's mother Adele, who was diagnosed with genetic early-onset Alzheimer's disease at age 55.

"I'm lucky I live with a very funny person," Lauren continued. "And as mom said back then, I'm funny sometimes too. For us, comedy is just sort of around and is absolutely part of how we cope with things naturally, whether we're aware of it or not."

She and Seth, 41, who tied the knot in Oct. 2011, launched HFC with a group of friends the next year. Lauren told PEOPLE at the time that her biggest piece of advice for others with a similar genetic disposition is "know yourself, know your numbers, know your genetic risk factors."

"Don't be afraid to deep dive into that," she said. "Because there are things that you can do to modify your genetics and to make lifestyle changes and live a brain-healthy life and potentially either delay or even maybe even prevent dementia or Alzheimer's.

"The one thing that I urge people is to talk to their doctors about their genetics and understand what it is that is inside of them that is going to affect their brains as they age, and not be afraid of that information …” Lauren added. “We should be talking about caring for our brains, and it shouldn't be scary.”
