And we decided to take on depression, and the reason we took on depression is because it's so prevalent, and as you know, there are many treatments for depression, with medication and psychotherapy, even electroconvulsive therapy, but there are millions of people, and there are still 10 or 20 percent of patients with depression that do not respond, and it is these patients that we want to help.
我们决定治疗抑郁症， 我们之所以选择它是因为它很普遍， 而且你们也知道，治疗抑郁症的方法有多种， 有药物治疗和心理治疗， 甚至有电休克疗法， 但在数百万人中， 仍然有百分之十到二十的患者 无法治愈，就是这些患者需要我们的帮助。
