Laura Prepon has revealed that her brother Brad died on July 15, 2026, following a sudden cardiac event that doctors never identified before it proved fatal.
The 46-year-old actress, famous for portraying Donna Pinciotti on “That ’70s Show,” shared the devastating news on Aug. 5, 2026, explaining that Brad Prepon was 48 when he succumbed to the undiagnosed cardiac condition. His family buried him during the weekend of Aug. 1.
“He passed away suddenly from an unknown heart condition — it was a devastating shock,” she wrote in a social media post that included photographs documenting decades of their sibling bond.
A Brother Defined by Intellect and Connection
Brad Prepon relocated to California in 2002, maintaining tight bonds with Laura and their three additional sisters throughout the years. His obituary highlighted a man consumed by curiosity, particularly regarding world history, with World War II holding special fascination for him.
Those who knew him recalled an analytical thinker who gravitated toward understanding mechanics and construction. Physical fitness mattered greatly to Brad, as did moments spent with loved ones during holiday celebrations and evenings out. His family noted that his singular personality left lasting impressions on everyone he encountered.
The memorial service celebrated his devotion to tennis and historical study, while emphasizing the warmth and vitality he brought to gatherings. His loved ones concluded the remembrance by noting he would live on through the irreplaceable qualities that defined him.
Public Appeal for Medical Vigilance
Laura Prepon used her announcement not only to mourn but to caution others. Because the cardiac issue that claimed her brother’s life went undetected, she implored followers to heed warning signals their bodies send and obtain prompt medical evaluation.
The actress told those reading her message to embrace their loved ones, acknowledging the emptiness Brad’s absence created for everyone who knew him and even those who never had the chance. She described him as someone she would carry forever in her heart, expressing gratitude for the impact he made during his time alive.
Career Highlights and Recent Struggles
Laura Prepon achieved stardom playing the red-haired Donna during “That ’70s Show,” which aired from 1998 to 2006, later returning to the character for “That ’90s Show.” She gained fresh recognition portraying Alex Vause, a former drug-cartel operative with dark hair, on “Orange Is the New Black.”
The performer has endured considerable personal hardship lately. The couple separated in September 2024 and Foster filed for divorce that November. In the filings Prepon accused him of “habitual drunkenness” and “cruel and inhuman treatment,” while Foster alleged conduct on her part that he said rendered further cohabitation “unsafe and improper.” The pair share two children together.
The actress has also discussed her battle with bulimia publicly. In her book “You and I, As Mothers,” she revealed that her mother instructed her in bulimic behaviors, creating childhood trauma that persisted beyond her eventual recovery. She reported that sharing her maternal relationship and eating disorder history prompted responses from numerous readers facing similar challenges with food and family dynamics, making the vulnerability meaningful if it helped even a single person.
Brad’s death represents another profound loss for Laura Prepon, who has grown more willing to discuss painful topics through her public presence. Her announcement of his passing followed that pattern, converting private heartbreak into a warning she hoped might prevent other families from experiencing the same abrupt devastation.
