I'm going to agree here, please change the slashdot headline and summary to reference Bipolar Disorder instead of Manic Depression and Depression.
I'm not going to go on a holy war about calling it Manic Depression, that's at least acceptable, but please DO NOT refer to it as it is in the summary, purely as Depression. When people say Depression (without the manic qualifier), they usually mean Major Depressive Disorder or Dysthymia, totally separate illnesses from Bipolar Disorder. It is mainly for this reason that the old Manic Depression term was dropped, because it made people perceive them as two separate parts of the same entity.
There has NOT been found in this article a link between Major Depressive Disorder and Schizophrenia, but between Bipolar Disorder and Schizophrenia. If someone could, please change this to suit.
Also, for more proof this is the right way to go, note that the first article linked does not, surveyed via Ctrl+f, reference Depression once.
