Sharon Stone is opening about the “brutally unkind” way people treated her after her stroke.

On Wednesday, the actress took on her role as an advocate for Alzheimer’s at an event in West Hollywood to raise awareness for the Women’s Brain Health Initiative.

Speaking to Variety, Stone said, “This is why I do it: My mother had a stroke. My grandmother had a stroke. I had a massive stroke — and a nine-day brain bleed.”

“People treated me in a way that was brutally unkind,” Stone recalled about the women in the industry who many would think would have been supportive.  “From other women in my own business to the female judge who handled my custody case, I don’t think anyone grasps how dangerous a stroke is for women and what it takes to recover — it took me about seven years.”

During her recovery time, the “Basic Instinct” actress said that she had to deal with both personal and professional losses.  “[From] trying to keep custody of my son to just functioning — to be able to work at all,” Stone added. “I was so grateful to [LVMH head] Bernard Arnault, who rescued me by giving me a Dior contract. But I had to remortgage my house. I lost everything I had. I lost my place in the business. I was like the hottest movie star, you know?”

She continued, “It was like Miss Princess Diana and I were so famous — and she died and I had a stroke. And we were forgotten.”

Stone is now working on reminding people to know the signs of stroke. She said, “if you have a really bad headache, you need to go to the hospital. 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.”

It wasn’t until Stone read her chances of survival in a magazine that she realized how bad it was. “No one told me.”
