BACKGROUND Reduced plasma tryptophan occurs in depression and somatization. Induction of indoleamine 2,3-dioxygenase (IDO) with consequent synthesis of tryptophan catabolites (TRYCATs) and lowered tryptophan are associated with the onset of depression in the puerperium and during interferon-alpha treatment. Depression is accompanied by lowered kynurenic acid, a neuroprotectant, or increased kyn...

PURPOSE Somatization is a common symptom among the elderly, and even though personality disorders have been found to be associated with somatization, personality traits have not yet been explored with regard to this symptom. The aim of this study is to investigate the relationship between personality traits and somatization, and social inhibition. PATIENTS AND METHODS As part of a cross-secti...

Somatization is a significant problem for clinical medicine. Unlike somatization disorder, which is relatively rare, abridged somatization, a less severe form of somatization, is prevalent in primary care clinics. The authors examined the clinical status and functioning of patients diagnosed with a depression or anxiety disorder comorbid with abridged somatization and compared them with patient...

BACKGROUND Psychological factors are associated with functional gastrointestinal (GI) disorders. Literature suggests that somatization is associated with functional dyspepsia (FD). However, the relationship between organic dyspepsia (OD), FD, and FD subtypes and somatization is poorly described. We aimed to examine this issue in a cross-sectional study of secondary care patients. METHODS Demo...

Somatization mechanisms are poorly understood. The authors tested whether somatization might involve altered central nervous system information processing. They measured somatization using the Somatization Sensation Inventory (SSI) and information processing style using the Hyperarousal Scale, scores of which correlate with electroencephalogram(EEG) measures of cortical electrical responsivenes...

BACKGROUND The association between anxiety and depression, and eczema is well known in the literature, but factors underlying this association remain unclear. Low levels of omega-3 fatty acids and female gender have been found to be associated with both depression and eczema. Somatization and health anxiety are known to be associated with anxiety and depression, further, somatization symptoms a...

Countless cross-sectional surveys of primary and secondary care have demonstrated the ubiquitous nature of medically unexplained symptoms. If grouping diverse symptoms under one heading is appropriate, they account for over half of all new presentations in secondary medical care (Nimnuan et al. 2001a) and a sizeable proportion of ‘frequent attenders ’ in secondary care have predominantly medica...

INTRODUCTION Defining somatization in pediatric populations presents a unique challenge, because DSM-IV somatization criteria may be inadequate for identifying a child with somatization. Two approaches exist. Child somatization has frequently been rooted in a questionnaire model, focusing on child or parent responses to assess how well a child conforms to a specific mental health profile. Other...
