Lauren Miller is sharing her story about an alarming health discovery she previously faced.

The actor and comedian unexpectedly revealed at the University of California, Los Angeles s (UCLA) Neurosurgery Visionary Ball in Beverly Hills this week that she had a brain aneurysm and only found it after being inspired by the Hilarity for Charity nonprofit, which she co-founded with her husband Seth Rogen , to get a full-body MRI.

Miller, whose grandmother and mom had dementia , said during her speech at the gala that she wanted to take a deeper look at anything that could possibly be lurking inside me that would affect my longevity. She discovered just that in 2018.

They found, of course, this sort of aneurysm in my head, the 42-year-old told her audience. So, of course, this was terrifying information and made me think of my great-grandmother, whose fate I certainly didnt want to mimic. Fortunately, it was relatively small.

She added, I did what the doctors recommended that I do, which is have annual MRIs [to] track the size.

Miller explained the aneurysm was small and remained so until it didnt as doctors noticed its sudden growth in the spring of 2022. The actor eventually found solace in Dr. Geoffrey Colby at UCLA, who answered every single question she had.

Miller decided to go under the knife to have the aneurysm removed.

The Superbad actor, who married Rogen in 2011 and launched Hilarity for Charity with him, previously told People her most valuable advice for any and everyone is to know yourself, know your numbers, know your genetic risk factors.

The comedian naturally opted to pepper her sincere speech Wednesday with some humor.
