This is a significantly different implication by far, to the point that the two statements do not even say (or imply the same thing). The symptoms of anxiety and depression are indeed mental health issues, but changing it to the broader category changes the message enough to be a False/unproven statement.

@dang, could we enlist your help in title-smithing for accuracy? Something along the lines of "ADHD traits a more reliable indicator of depression/anxiety vs ASD" or the like.
