BACKGROUND: According to one of the diagnostic criteria of the dsm iv for @entity13299 there has to be a temporal relationship between psychological factors and the onset, or the worsening, of the symptoms. This criterion has been omitted in the @entity4987 . Another criterion, namely that the symptoms are not produced intentionally, has also been abandoned. A new recommendation is that therapists should look for neurological symptoms that support the diagnosis.<br/> AIM: To investigate whether studies support the changes in the criteria.<br/> METHOD: We searched literature using PubMed.<br/> RESULTS: When the symptoms first appear, @entity130 or stress in 37% of @entity1 is of a physical rather than a psychological nature. Different forms of stress were found in equal proportions (20%) in @entity1 with or without @entity13299 . There are no specific stressors, except possibly in @entity1 with @entity7364 . The percentages of childhood abuse vary widely, namely from 0 to 85%. The characteristic phenomenon of 'la belle indifference' occurs in only 3% of @entity1 with @entity13299 versus only 2% of controls. Most of the 'positive' clinical tests for partial @entity912 and sensory and gait disorders are highly specific. There are no reliable tests for distinguishing @entity13299 from simulation.<br/> CONCLUSION: The changes of the criteria are supported by recent studies.
