Leader writes of Western Culture's current failures to define and treat madness. Western nations currently aim to treat the symptoms of psychosis and to bring the patient's behaviors into line with social norms without understanding or treating the roots of the disease.
Many "symptoms" of psychosis, Leader argues, are actually not symptoms of the underlying disease but adaptations the patient makes to try to adjust their understanding of the world to how the world actually works. The disorders listed in the DSM and the symptoms that define each disorder seem to be defined by the pharmaceutical companies that have a drug to treat each symptom.
Leader distinguishes between going mad and being mad, remarking that some psychoses have no symptoms until something triggers them. The symptoms can go into remission once the triggering event has passed, but that does not mean the psychosis has disappeared. It just continues to exist in a form that doesn't alarm the neighbors.
Leader examines three famous cases of psychosis, or potential psychosis, including Lacan's Aimee, Freud's Wolf Man, and the British serial killer physician, Harold Shipman, who murdered 250 of his patients. The case of Aimee is especially interesting and makes me want to read Lacan's original writing on the subject. I found the entire Wolf Man chapter annoying because I find Freud annoying. How can such an astute observer as Freud insist on bending all interpretations to his pet theories? The final case, Shipman, is simply baffling. He seemed to want to take his secrets to the grave.
The final chapter, Working with Psychosis, is fascinating for its description of what it's actually like to work with psychotic patients. The author reiterates that one of the most important aspects of treating psychosis is to understand what symbols, events and ideas actually mean to psychotics, and to help them build meaning that they often can't seem to build for themselves. This is a task that requires years, if not decades of work. It's not profitable to the drug companies or to insurers or hospital chains, so it's not a type of treatment we pursue.
The afterword is also interesting for its summary of recent Western attitudes toward mental illness. In the US, in the early twentieth century, many states prohibited the mentally ill from ever marrying. Some wanted to forcibly sterilize the mentally ill. There was even a movement in the US to exterminate the insane, in the name of eugenics, to improve the human gene pool. That plan didn't quite take off in the US, but the Nazis picked it up, just as they picked up toxic rhetoric and discriminatory laws against American Blacks and applied them to European Jews.
I sometimes think we live in a unique age of social and political insanity, but Leader's afterword these strains of nastiness have run through Western civilization for quite some time.
