The National Institute of Mental Health (NIMH) will no longer use the Diagnostic and Statistical Manual of Mental Disorders to guide its research. Instead, NIMH is working on a long-term plan to develop new diagnostic criteria and treatments based on genetic, physiologic, and cognitive data rather than symptoms alone. Frank Farley, a psychologist at Temple, isn't convinced that the whole process doesn't need to start from scratch, however. "What it suggests is that we need to go back to the drawing board,” he said.
