BOOMING TUNES OF GLOOM

Depression again figures strongly in this issue, with not all tunes in a minor key. When I look at scientific papers of the late 19th and early 20th centuries it is amazing how little there was published on what we now know is a most common and crippling condition (Reference Üstün, Ayuso-Mateos and ChatterjiÜstün et al, 2004). Even when Adolf Meyer substituted the term ‘depression’ in place of ‘melancholia’ in 1904, as the latter ‘implied knowledge we did not possess’ (Reference ShorterShorter, 2005), we still persisted in grouping all depression under Kraepelinian manic-depressive illness or the even less satisfactory ‘involutional melancholia’. We are certainly making up for this neglect now - all but three of the papers in this issue are concerned with depression, but not focusing primarily on mood. First, readers may not all have noticed that the generic word ‘psychosis’ is creeping back into general parlance, and this includes depression in psychotic forms in the same breath as schizophrenia. Thus, all four papers on psychosis in this issue (Aleman et al, pp. , Clarke et al, pp. ; Dean et al, pp. ; Wade et al, pp. ) include depression in psychotic form as a (relatively small) group within the population. This, as Dean et al have noted, sometimes makes it difficult to compare current studies with past ones but it is surprising how few are the differences found between schizophrenia and other psychoses, with the only study showing differences limited to insight (Aleman et al, Table 2, p. ). It seems that, almost unheralded, people have taken on board the message of one of our earlier editorials (Reference Craddock and OwenCraddock & Owen, 2005) and abandoned the Kraepelinian dichotomy for Griesinger's Einheitspsychose.

But this does not mean other forms of depression should necessarily be absorbed into the grand symphony of psychosis. The funeral march association of depression with suicide is well known, with greater risk with more severe depression (Reference Grunebaum, Galfalvy and OquendoGrunebaum et al, 2004); what is less well remembered is that depression can be associated with early mortality and this is shown in the paper by Mogga et al (pp. ) from Ethiopia, in which clear evidence of suicide does not seem to have been found - but was it hidden? Suicide itself is also know to be related to ease of availability of noxious substances, and the editorial by Bertolote et al (pp. ) is a wake-up call to the rest of us dozing unaware that pesticides account for one in three suicides world-wide. Eddleston et al (pp. ) show that the risk of death from yellow oleander poisoning is three times greater in the elderly than in the young, and that this may have been an underrated cause of greater suicide rates in the elderly. So with so much depression around it is good to report that we may have a new effective treatment, vagus nerve stimulation (Corcoran et al, pp. ), which will need much more work to set it into context, but is certainly exciting. The other highly topical subject in depression research is the extent of neurocognitive deficits in those with bipolar disorder. This is now well established in classical bipolar disorder (Reference Thompson, Gallagher and HughesThompson et al, 2005) (to date, our most cited article from 2005) and the paper by Torrent et al (pp. ) takes this a further step forward by showing impairments in bipolar II disorder that are intermediate between those of bipolar I and control participants. Yet another ‘variation on a theme by Griesinger’.

RESEARCH ASSESSMENT EXERCISE AND THE JOURNAL

Last month we discussed impact factors with a climbing metaphor. The Research Assessment Exercise is aptly named as it involves academics in England and Wales desperately straining to complete their climbs before 31 December 2007, because it is only papers that are published by this date that will be considered for the assessment of excellence that will determine university department funding for the subsequent 5 years. I hope that potential authors in other parts of the world will show sympathy for all the climbers - the tough Munro competitors climbing journal steeps over 3000 ft, the less ambitious Emslie mountaineers attempting ascents of up to 2000 ft - and even have a thought for those staggering up the Marilyns (hills with a drop of 150 m all round) as they struggle with their heavy manuscripts. This month the preparations for the last climb begin and, because of the common strategy to maximise performance (Reference Goldberg and MannGoldberg & Mann, 2006), we expect an increase in manuscript submissions in the next year. So please note that we may be even more competitive than usual but, in acknowledgement of the pain and suffering involved, and with an apology to our international contributors for being mildly partial, we will ensure that all papers from England and Wales accepted by 1 June next year will be published by the end of 2007, even if we have to produce bumper issues to do so.
