But if he'd expected an avuncular smile of approval, he was mistaken. Zametkin angrily barked at Amen that these techniques were strictly for research and in no way intended for clinical use. In no uncertain terms, he told Amen, in effect, to cease and desist what he was doing.
"But why do you do these studies if you don't intend this technology to be used clinically?" Amen asked, baffled.
"I do them just to learn more; it's interesting basic science," Zametkin replied loftily.
This is an attitude foreign to Amen. "I really have no interest in science for science's sake," he admits. "I'm a clinician through and through--it's my reason for living. I get my juice from my practice, from relationships with patients, not from research."
Back home in California, the natives were also getting restless. A local pediatric neurologist, after calling three or four researchers around the country and hearing that SPECT wasn't ready for clinical prime-time, complained to hospital officials about Amen's heterodox behavior. "The neurologist told me that my reasons for ordering scans weren't empirically proven, and that I should quit doing them. He said, 'The brain is for neurologists, not psychiatrists,'" Amen recalls, even now incredulous. "I told him he was nuts." At a meeting of the hospital authorities, Amen was given permission to continue getting SPECT scans for his patients, but he was now required to have the medical director sign off on his requests.
In 1993, he was asked to help teach a brain-imaging course at the APA annual meeting, but when the program came out, a Dallas SPECT researcher wrote the APA program chairman demanding to know why such a controversial figure was included. The program committee chair sat in on the presentation and supported Amen's work, but many others were openly hostile to him, making a point of telling him he was a fraud and a mountebank and ought to be drummed out of the medical profession. It had gotten to be too much, so he decided to retreat from the public field, help his patients in the relative privacy of his clinical practice, and let other people do the research and fight the battles.
