  • what is conversion disorder?

  • Satyam,
    It was formerly called hysteria.
    It is not intentional as many people think, think misconception should be erased.

    As per ICD and DSM:

    Conversion disorder is a condition where patients present with neurological symptoms such as numbness, paralysis, or fits, but where no neurological explanation can be found. It is thought that these problems arise in response to difficulties in the patient’s life, and conversion is considered a psychiatric disorder in the International Statistical Classification of Diseases and Related Health Problems (ICD-10) and Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV)
