Barbara Arrowsmith-Young was born with severe learning disabilities that caused teachers to label her slow, stubborn—or worse. As a child, she read and wrote everything backward, struggled to process concepts in language, continually got lost, and was physically uncoordinated. She could make no sense of an analogue clock. But by relying on her formidable memory and iron will, she made her way to graduate school, where she chanced upon research that inspired her to invent cognitive exercises to “fix” her own brain. With great inventiveness, she expanded and refined these exercises to the benefit of thousands of individuals since. The Woman Who Changed Her Brain interweaves her personal tale with riveting case histories from her more than thirty years of working with both children and adults. The idea that self-improvement can happen in the brain has now caught fire.
