These practical guidelines for the biological treatment of unipolar depressive disorders in primary care settings were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). They embody the results of a systematic review of all available clinical and scientific evidence pertaining to the treatment of unipolar depressive disorders and offer practical recommendations for general practitioners encountering patients with these conditions. The guidelines cover disease definition, classification, epidemiology and course of unipolar depressive disorders, and the principles of management in the acute, continuation and maintenance phase. They deal primarily with biological treatment (including antidepressants, other psychopharmacological and hormonal medications, electroconvulsive therapy, light therapy).

This largest study on time sense in manic patients confirmed results of a divergent alteration of time experience in depressive and in manic patients but revealed an uniform time overestimation by both patient groups in time judgment tasks.

This study provides detailed descriptive data regarding the frequency (cross-sectional) and characteristics of hallucinations in a large sample of patients with BPD, major depression or schizophrenia. Our results suggest a link of lower education and the presence of hallucinations in major affective disorders. The significance of this finding, as well as the role of anxiety in hallucinating patients, requires further study.

In most patients with a significant cross correlation between sleep and/or bedrest and mood, the mood change occurred on the day following the change in sleep and/or bedrest. Sleep changes from a previous pattern, especially those of more than 3 h, may indicate that a large mood change is imminent.
