Sizemore was hospitalized on Feb. 18 after suffering a brain aneurysm that occurred as a result of a stroke, Lago previously confirmed to Fox News Digital. He was placed in critical condition and was receiving intensive care at the hospital. 

"His family is aware of the situation and are hoping for the best," Lago said at the time. "It is too early to know about [a] recovery situation as he is in critical condition and under observation."

On Feb. 27, things took a turn for the worse, with Lago confirming, "Doctors informed his family that there is no further hope and have recommended end-of-life decision."

"The family is now deciding end-of-life matters."

Per Mayo Clinic, a brain aneurysm is described as the "bulge or ballooning in a blood vessel in the brain" that "can leak or rupture, causing bleeding into the brain (hemorrhagic stroke)."

TOM SIZEMORE’S DOCTORS 'HAVE RECOMMENDED END OF LIFE DECISION' AFTER BRAIN ANEURYSM

Sizemore enjoyed a successful run in Hollywood in the late 1990s to early 2000s starring in blockbuster films including "Black Hawk Down" and "Heat." His career then took a hit following issues with substance abuse and arrests for DUI, domestic abuse, and possession of a controlled substance. 

In 2013, he released a memoir detailing his "wild ride through Hollywood," titled, "By Some Miracle I Made It Out of There."

A synopsis of the book said Sizemore’s days had been "filled with overdoses, suicide attempts, and homelessness." 

The memoir was "a harrowing journey into the heart of his addiction, told in riveting and often shocking detail. By turns gritty and heartbreaking, it is also one man’s look at a particular moment in entertainment history—a window into the drug-fueled spotlight that sent Robert Downey, Jr., to jail and killed River Phoenix, Heath Ledger, Chris Farley, and many others far before their time."

In an interview with Fox News Digital in 2021, Sizemore shared his commitment to getting sober, saying "I’ve been trying to get sober since 1991 ... It became really big news much later than that, but I was trying to stop. I’ve had a problem for a long time. I had periods, long periods, of sobriety and I would end up relapsing."

"I still go to meetings and work my steps, but I had reached a place in my life where I knew I had to stop," he explained. "I couldn’t be arrogant anymore. If I wanted to reach a nice and pleasant old age, I had to stop. And if I wanted to watch my kids grow up, I needed to reach a place where I knew it was over."

"So far, it has remained over," he noted. "I still have to do my daily inventory and show up."
