    Symptoms of a conversion disorder include the loss of one or more bodily functions, such as:

    • Blindness
    • Inability to speak
    • Numbness
    • Paralysis

    Diagnostic testing does not find any physical cause for the symptoms.

    Signs and tests

    Common signs of conversion disorder include:

    • A debilitating symptom that begins suddenly
    • A history of a psychological problem that gets better after the symptom appears
    • A lack of concern that usually occurs with a severe symptom

    Your doctor will do a physical examination, and possibly diagnostic tests, to rule out physical causes for the symptom.
