Schizophrenia is one of the most devastating and mysterious mental illnesses. People with schizophrenia have the unique sensation that their brain is being taken over by external entities and that their heads are filled with voices that are not their own. Although it is increasingly recognized as a biological illness of the brain, it also has profound psychological implications for how we perceive reality. The Madness Within Us: Schizophrenia as a Neuronal Process is an illuminating discussion of these two aspects of the illness. Dr. Robert Freedman, who is both a neuroscientist and a practicing clinical psychiatrist, outlines the emerging understanding of shizophrenia as a neurobiological illness and shows how these new insights can be used as a bridge to the psychological understanding of the delusions and hallucinations. He combines the findings of modern brain science with insights from the clinical practitioner's empathic listening to patients as they describe their problems.
