But how do you <i>know</i> the condition is psychogenic?  You seem to have jumped to this conclusion based on your experience with other patients whose symptoms turned out to be psychogenic.  Even granting that there&#x27;s some similarity in the symptoms, I don&#x27;t see how that provides strong evidence that this condition is also psychogenic.<p>I&#x27;m not saying it&#x27;s an unreasonable hypothesis, but how can one have enough confidence in it to abandon the search for organic causes?  -- Particularly when, if there <i>were</i> an organic cause that therefore got overlooked, the cost to the patient would be very high.
