Sharon Stone revealed she was treated in a way that was "brutally unkind" after she had a "massive stroke and four day brain bleed".
She told Variety at a Women's Brain Health Initiative event that she had to re-mortgage her house, despite being one of the world's "hottest movie stars" as she struggled to recover.
Now, she wants to share her story with others in a bid to help people to spot the signs of a stroke early.
"If you have a really bad headache, you need to go to the hospital." She said.
"I didn't get to the hospital until day three or four of my stroke. Most people die. I had a 1% chance of living by the time I got surgery – and they wouldn't know for a month if I would live."
The NHS advice is aligned with Sharon Stone's, telling people to act F.A.S.T, which stands for face, arms, speech and time.
The main symptoms of a stroke are a dropped face on one side, the inability to lift both arms and slurred or garbled speech. If you suffer from any of these symptoms, acting quickly is imperative.
Other symptoms might include dizziness, confusion and a severe headache.
Game of Thrones star, Emilia Clarke, suffered from a life-threatening type of stroke known as subarachnoid haemorrhage (SAH) in 2011 with further surgery needed in 2013.
She said the producers of Game of Thrones ensured she had all of the professional support she needed throughout her recovery, a different experience to the one Sharon Stone had.
Stone said she was very thankful for Bernard Arnault who "rescued" her by giving her a contract with Dior.
"I lost everything I had. I lost my place in the business. I was like the hottest movie star, you know? It was like Princess Diana and I were so famous – and she died and I had a stroke. And we were forgotten."
If you think you or somebody else is having a stroke, phone 999 immediately and ask for an ambulance.
