Abstract:
:This paper reports a replication study of a four-group cluster-analytic typology of depressed patients. Several hierarchial agglomerative clustering procedures were applied on the original patient sample using a slightly reduced variable pool. The best replication obtained used Ward's error sum of squares method and was stable on iterative relocation. Three groups, psychotic depressives, anxious depressives, and young depressives with personality disorders replicated well, while hostile depressives failed to separate clearly from the young depressives.

杂志文章abstract:BACKGROUND/AIMS:Neurotrophins such as brain-derived neurotrophic factor (BDNF) are vital for neuronal survival and adaptive plasticity. With high BDNF gene expression in the prefrontal cortex, BDNF is a potential regulatory factor for building and maintaining cognitive reserves. Recent studies suggest that individual d...
