Costello’s book has three focal points that complement and illuminate each other. The first is the story of the author’s son who was diagnosed with schizophrenia in his teens. The second is the mother’s search of her family tree for clues as to where the illness came from, how mental illness may have affected her ancestors, and ultimately, how it affects her present family. Lastly, the author discusses past, present, and possible future descriptions of the course and treatment of this disorder. …In short, A Lethal Inheritance tells how far we have come in understanding schizophrenia and yet how far away we are from fully comprehending and effectively treating it. By focusing on individuals with mental illness, their families, and large populations, Costello gives a good overview of where we are now in the journey to uncover the causes and treatments for mental illness.
