Irish woman Samantha Campbell, 34, was diagnosed with Jeavons Syndrome as a child, BelfastLive reports.

Later, she developed an incurable disease, which was accompanied by constant nervous twitches and tremors throughout the body.

And two years ago, the woman started having seizures, but she could not go to the doctor for a long time.

But over time, the frequency of seizures increased, and doctors diagnosed her with functional neurological disorder (FND).

"In 2022 I had mild jerking on the left side of my body, through my arm and head. It was maybe happening once or twice a week but not raising any concern. I thought it was stress-related due to a family situation. But as the months passed, it got more and more frequent. It began extending to my leg then becoming more frequent with attacks happening several times a week," said Campbell.

The therapy, which was supposed to help reduce the intensity of the symptoms, did not bring relief. As a result, the woman lost the ability to move her leg as normal, and now she has to use a cane.

Also, she started having speech problems and constant dizziness.

According to doctors, as of today, there is no effective treatment for FND.
