- “Unexplained parental illnesses may predispose children to similar fate,” WebMD Health News, 1999 Dec 17. “One of the biggest problems I have with this study is that the determination of whether patients’ symptoms were explained or not was made by a team of psychiatrists and was based on the questionnaires, not a physical examination. I’m not sure the symptoms would have been unexplained if such an exam were done.”
