"I’ve come to see now, by doing the research myself and spending hours looking at numbers, that the medication is absolutely doing something," Hunter says.
In an earlier study that Hunter published in 2009, she and her team used the same QEEG technique on 58 patients, who were given a placebo daily for one week before being randomized to take either placebo or an active drug.
