Quoting an unnamed senior investigator, Die Welt said that Lubitz appears to have suffered from severe depression and "strong subjective burnout syndrome," receiving treatment from "several neurologists and psychiatrists" before this week's deadly crash.
The new report follows similar stories from The New York Times and The Wall Street Journal. Also citing unnamed officials, those papers reported that Lubitz was being treated for depression with prescription drugs (a condition he concealed from his employer) and sought treatment for a potentially psychosomatic vision problem.
On Sunday, The Washington Post reported that handwritten documents found in Lubitz' apartment revealed the pilot was experiencing "deep stress" over his eye issues, believing they threatened his future in his dream career.
