Jenna Jameson 'wasn't able to walk' before being hospitalized and diagnosed with a rare neurological disorder, her partner says

• Jenna Jameson said on Instagram that she had been diagnosed with Guillain-Barré syndrome.
• The syndrome, per the NIH, causes the body's immune system to attack part of its nervous system.

Jenna Jameson said in an Instagram video post that doctors suspected that she has Guillain-Barré syndrome, a day after her partner posted a video on her account saying that she had lost the ability to walk and had been admitted to the hospital.

The former adult film star, who is 47 years old, shared her diagnosis on Instagram in a Monday post that's been viewed over 100,000 times.

"I'm dealing with a little syndrome called Guillain-Barré syndrome," Jameson said in the video, which she said was posted from a hospital in Hawaii.

"I just had an infusion and we're just working towards getting better," Jameson said later in the video.

Jameson's partner, Lior Bitton, had previously posted a video on Jameson's account on Sunday confirming that she had been hospitalized.

Bitton said in the video that Jameson had been "throwing up for a couple weeks" and underwent a CT scan. Two days later, he said that Jameson's legs were unable to hold her weight.

According to the National Institutes of Health, Guillain-Barré syndrome is a rare neurological disorder in which a person's immune system attacks parts of their peripheral nervous system, which is located in the brain and spinal cord.

Its exact causes are unknown, and the severity of illness can range from "brief weakness to nearly devastating paralysis," per the NIH. According to the NIH and the United Kingdom's National Health Service, there is some evidence that Guillain-Barré syndrome can occur following an infection. Experts believe it may be the immune system activating to fight the infection, but later targeting nerve cells.

In her post, Jameson, who Jezebel reported has made anti-vaccine comments in the past, said that the syndrome was "NOT a reaction to the jab" or "any jab." In July, the Food and Drug Administration issued a warning about reports of Guillain-Barré and Johnson & Johnson's coronavirus vaccine, Insider previously reported. The FDA said that the evidence was not sufficient to establish a causal relationship between the two. There are also reports of patients developing Guillain-Barré syndrome as a complication of COVID-19.

In her post, Jameson said that she was beginning IVIg (intravenous immunoglobulin) treatment, which is commonly used to treat Guillain-Barré, according to the NIH.

"I am in the hospital and will likely remain here until treatment is complete," Jameson said. "Thank you for your concern."
