After the 7-year-old suffered a grand mal seizure at the end of January, doctors at Children's of Alabama in Birmingham uncovered multiple cerebral malformations in her brain that need "immediate attention." The surgeries are to help prevent Liza from having any further seizures as well as possible brain bleeds, hemorrhages or strokes, according to her fundraising page.
For the past month, Liza has spent part of her days selling her homemade lemonade for 25 cents a cup. Already, the stand has raised anywhere from $15,000-$20,000 [to help pay for her surgery], her mom said.
