Fort Worth — For Alaina Palmer, school has always been a struggle.The Central High tenth-grader was diagnosed with dyslexia at a young age. In fifth grade, Alaina was bullied because of her learning problems. She came up with a saying, “Imagine a scar you can’t feel, see or touch, but you know it’s there. That’s dyslexia.”On Thursday night, about 150 parents, educators and students gathered at Central High School to watch an HBO documentary, “The Big Picture: Rethinking Dyslexia,” and participate in a Q&A discussion.According to the film, one in five students and adults have dyslexia. Researchers have traced the disorder to neural pathways in one part of the brain that function less efficiently. While those with dyslexia struggle with reading and language skills, they also have many strengths. Persons with dyslexia tend to be bright, creative and good at grasping big-picture solutions.The documentary interviewed a number of high-achieving people with dyslexia, including Virgin founder Sir Richard Branson and financier Charles Schwab, and students and adults who have overcome obstacles to their education and careers.Alaina said the message reminded her that she is not alone in her struggles. As a singer and songwriter, she was encouraged that many people with dyslexia are gifted with creativity.Central freshman Mary Roggenbuck said the movie was inspiring.“It was good to see that all we have to do is work harder,” she said.Those with dyslexia often need extra time to complete tests, and they need to find their own methods to study and learn material.Parent Jessica Bryant said the documentary was very helpful, both for her and for her fourth grader who has dyslexia.“As a parent, I think it illustrates dyslexia in a way we can understand,” Bryant said. “There are a wide variety of symptoms and differences in their learning, but it gives you hope.”Her daughter benefited from the film by realizing that she may struggle with reading, but she sees the big picture and can do great things. After a boy in her class was diagnosed with dyslexia, she told him that there wasn’t anything wrong with him; his brain just worked differently, Bryant said.Bryant recently helped start a parent support group called Password.At last week’s event, dyslexia teachers from across the district were on hand to talk with parents. Fossil Ridge teacher Sue Testerman answered questions from the audience.“It’s so important for these kids to have strong parental support because school is not easy,” Testerman said.She urged parents to be honest with their children and help them begin to advocate for themselves.“They need to be able to ask for help when they need it,” she said.Central High dyslexia teacher Nancy Disterlic recently switched from teaching second grade. Disterlic was diagnosed with dyslexia in college, so she realized she was in a unique position to help others. These are brilliant kids who have so much potential.“Because my brain is like theirs, I really understand the differences, the frustrations and the flow of their thinking,” Disterlic said.
