Brett is intense. Intense as a youth piecing together the world. Intense as an undersized point guard, middle child, and student. Intense as a professional poker player, manager, and problem solver. But most notably, intense as an unaware manic mind set free in the world. Crossover: A Look inside a Manic Mind is a personal memoir detailing the evolution of psychotic thoughts and how they influenced Brett's behavior during the three manic episodes that spanned the past decade of his life. Through basketball, poker, and work, Crossover offers a firsthand account of how the world looks and feels as a person with Bipolar I from childhood traits to adult expression. Brett's recall of these incidents is so detailed because he has a rare condition called hypermnesia, an unusually enhanced, vivid, and precise memory. His perspective sheds light on the progression of bipolar disorder and will enhance your ability to learn and empathize with those affected by the illness. Suicide among people with bipolar disorder is thirty times higher than the general population, yet the cause and prevention remain a mystery. Brett's story is educational and inspiring for anyone who suffers from or has been affected by mental illness. It is a must read for medical professionals, therapists, students, and teachers.
