Schizophrenia Pre-Diagnosis Results Mixed

From the NY Times:
In recent years, psychiatric researchers have been experimenting with a bold and controversial treatment strategy: they are prescribing drugs to young people at risk for schizophrenia who have not yet developed the full-blown disorder.

The hope is that while exposing some to drugs unnecessarily, preemptive treatment may help others ward off or even prevent psychosis, sparing them the agonizing flights of paranoia and confusion that torment the three million American who suffer schizophrenia.

Yet the findings from the first long-term trial of early drug treatment, appearing today in The American Journal of Psychiatry, suggest that this preventive approach is more difficult to put into effect — and more treacherous — than scientists had hoped.

Daily doses of the antipsychotic drug Zyprexa, from Eli Lilly, blunted symptoms in many patients and lowered their risk of experiencing a psychotic episode in the first year of treatment, the study found. But the drug also caused significant weight gain, and so many participants dropped out of the study that investigators could not draw firm conclusions about drug benefits, if any.
