Functional (psychogenic) XXXX - Clinical presentations.

@entity308 @entity2045 @entity148 @entity400 @entity426 @entity717 @entity3519 @entity130
UNASSIGNED: Functional or psychogenic @entity717 are common and disabling, and sometime difficult to diagnose. The history and physical exam can give positive features that will support the diagnosis, which should not be based solely on exclusion. Some clues in the history are sudden onset, intermittent time course, variability of manifestation over time, childhood @entity130 , history of other somatic symptom and secondary gain. @entity148 and @entity308 are common, but not necessarily more than the general population. On examination, distraction and suggestibility may be present. There are specific signs that should be looked for with different types of movements. For example, with @entity400 , change in frequency over time and entrainment are common features. With @entity2045 , the movements might be complex in type with long latencies to stimulus induced jerks. @entity426 show good balance despite claims to the contrary. Functional @entity3519 still remains a challenging diagnosis in many circumstances, although fixed @entity3519 is one sign more likely to be functional.
