San Francisco, California, January 7, 2011 - Twenty-Three-year-old Savanna Kelley (lying in bed) spends time with her parents Marisa Martin (left) and Bryan Kelley at the University of California San Francisco Medical Center where she is undergoing a brain surgery to separate the Corpus callosum, a broad band of nerve fiber joining the left and right side of the brain. When Ms. Kelley was three she developed leukemia. With her father serving time in Iraq during the first Gulf War, her mother made the decision to try an experimental chemotherapy. Ms. Martin says this treatment stunted Ms. Kelley's mental growth. A few years later Ms. Kelley began to have seizures. These seizures have intensified more recently causing her to black out and collapse, causing further head trauma when she is standing. Her doctor, Edward Chang, believes separating the Corpus callosum will minimize the seizures. .
