A 6-year-old girl from Aledo, Texas, is set to have half of her brain removed to combat a life-threatening disorder, according to a report from The Dallas Morning News.

Jessie Hall suffers from Rasmussen's encephalitis, a rare illness that has plagued her for the past year, according to the report.

Though she walks, runs and plays T-ball, Jessie has suffered multiple seizures, lost the use of her left arm and may lose her vision, her father Cris Hall said.

"We've had a crash course in neurology," her father told The Dallas Morning News. "It's a progressive disease that basically keeps eating away at the right side of the brain."

Jessie is expected to undergo a hemispherectomy — a procedure in which one cerebral hemisphere (half of the brain) is removed or disabled — later this year at Johns Hopkins Hospital in Baltimore.

If all goes well, Jessie will awake from surgery with the left side of her body paralyzed for about five days, he said. She will have months of challenging rehabilitation following surgery.

Before having the surgery, however, the family will enjoy a vacation at Disney World in Orlando, courtesy of the Make-a-Wish Foundation.

Lets all make a prayer for her.
