Drawing on her research, knowledge, and clinical experience, internationally respected neurologist and mother of two boys Frances E. Jensen, MD, offers a revolutionary look at the adolescent brain, providing remarkable insights that translate into practical advice both for parents and teenagers. Driven by the assumption that brain growth was almost complete by the time a child reached puberty, scientists believed for many years that the adolescent brain was essentially an adult one only with fewer miles on it. Over the last decade, however, neurology and neuroscience have revealed that the teen years encompass vitally important stages of brain development. Motivated by her experience of parenting two teenagers, renowned neurologist Frances E. Jensen, MD, gathers what we've discovered about adolescent brain functioning and wiring, and in this groundbreaking, accessible book, explains how these eye-opening findings not only dispel commonly held myths about teens but also yield practical suggestions for adults and teenagers negotiating the mysterious and magical world of adolescent biology. Interweaving clear summary and analysis of research data with anecdotes drawn from her years as a clinician, researcher, and public speaker, Dr. Jensen explores adolescent brain functioning and development in the context of learning and multitasking, stress and memory, sleep, addiction, and decision making. Examining data connecting substance use to lingering memory issues and, sometimes, a lower adult IQ, The Teenage Brain explains why teenagers are not as resilient to the effects of drugs as we previously thought; reveals how multitasking impacts learning ability and concentration; and examines the consequences of stress on mental health during and beyond adolescence. Rigorous yet accessible, warm yet direct, The Teenage Brain sheds new light on the brains and behaviors of adolescents and young adults, and analyzes this knowledge to share specific ways in which parents, educators, and even the legal system can help them navigate their way more smoothly into adulthood in our ever challenging world.
