pre-psychosis to active psychosis," Heinssen says. "But active psychosis is
often present for weeks and even months before drugs are given."
Cannon, Heinssen, and colleagues also hope to move beyond symptoms to
identify biological markers that indicate a high risk for psychotic
Studies are planned or are under way examining the chemical changes within
the brain, hormonal changes, and changes in cognitive function in people with
Just as cholesterol and blood pressure are now used to assess heart disease
risk, these measures may one day help physicians determine someone's risk for
psychosis, Cannon and Heinssen tell WebMD.
