Y1 - 2012 N1 - T2 - Movement Disorders, 3e AB - In 1922, Sir Henry Head wrote: “…Hysteria is sometimes said to imitate organic affections; but this is a highly misleading statement. The mimicry can only deceive an observer ignorant of the signs of hysteria or content with perfunctory examination.”1 Although in many cases of psychogenic movement disorders (PMDs) the nature of the problem is quite obvious from the first patient encounter, in the majority the diagnosis requires careful analysis of the history and the phenomenology of the abnormal movements and occasionally prolonged periods of observation and assessment. In general, abnormal movements and postures due to primary psychiatric disease are among the most difficult diagnostic problems in neurology even for the most experienced neurologist.
