Conversion disorder - review
ln modern medicine the term “functional symptoms”
is usually used to refer to symptoms where an organic
cause cannot be found. Studies have shown that up to
half of all patients consulting their family physician and
approximately one third of all those attending neurology
outpatient clinics present with such symptoms. These
patients commonly go between doctors, repeatedly
undergo unnecessary tests, even surgery, and various
drugs are tried with limited success. These problems
tend to be prolonged and greatly reduce the quality

of life for the patients involved. Both the DSM IV and
ICD 10 classifications include a group for the so-called
medically unexplained disorders. Among these disorders
is conversion disorder where patients present with
neurological symptoms, affecting motor or sensory
function, but with no neurological explanation. Here we
provide an overview of the current ideas on the aetiology,
diagnosis, treatment and prognosis of conversion disorder.
Keywords: conversion disorder, functional symptoms, functional MRI, rehabilitation
