title: Comparison of the diagnosis of melancholic and atypical features according to DSM-IV and somatic syndrome according to ICD-10 in patients suffering from major depression.
abstract: While melancholic (according to DSM) or somatic syndrome (according to ICD) has strong historical roots and substantial empirical verification, the concept of atypical features is relatively new and not sufficiently studied. The aim of the current study was to investigate the reliability of these diagnostic subcategories in patients suffering from major depression in Greece. Forty patients (eight males and 32 females) aged 19-60 years (mean 39.3, sd 12.2) suffering from major depression according to DSM-IV criteria were studied. SCAN v.2.0 was used to assess symptomatology. The presence of each criterion according to DSM-IV and ICD-10 was registered. Frequency tables were developed and factor and cluster analysis were performed. The results of the analysis suggest the existence of three syndromes which roughly reflect the melancholic and atypical but also propose a third, which can be considered as an 'undifferentiated' syndrome. The DSM demand that the existence of melancholic features be excluded first and then that diagnosis of atypical features be made was confirmed.
