[The influence of child's behaviour on the course of neurological diagnosis].

INTRODUCTION: Among the huge amount of neurological diseases that cause diagnostic difficulties, there happens, from time to time an additional difficulty--disorders of psychogenic origin, and among those- conversion disorders. Until now there still is no satisfactionary explanation for the neurobiological basis of conversion. The explanations offered by psychology are also rather general, based on the tradition of psychoanalysis. Aside from how deeply one understands its mechanisms, when suspecting a psychogenic origin of the symptoms observed, one should be especially careful. It is far too easy falling in the trap, that hysteria sets for us, suggesting to be the patient's one and only disease that should be dealt with.

AIM OF THE STUDY: To show the difficulties and dangers when making a diagnosis of functional disorders, both from the physician's and psychologist's point of view.

MATERIAL AND METHODS: Presenting cases of 6 patients, whose behaviour and symptom presentation suggested a psychogenic background of the disorders, and only few of the psychological tests' results differentiated between the organic and the psychogenic group.

RESULTS: In the presented group there were 3 children diagnosed with conversion disorder, and 3 diagnosed with neurological diseases. The psychological test results only partly differentiated between both groups, not allowing any interpretation to be based on quantitative results only.

CONCLUSIONS: 1. Even though medicine has made such a huge step forward, conversion disorders can still cause serious diagnostic difficulties. 2. Leaving our knowledge about human mind aside, we are continously eager to base our judgement on the most vivid elements, that present to us most clearly. 3. That line of thinking puts us in jeopardy of missing the obvious: that a histerical person can also suffer from another condition of a very organic origin.
