I appreciate your reply, and I understand your point.  A misdiagnosis in either direction along the organic&#x2F;psychogenic axis will have unfortunate consequences for the patient.  Fair enough.<p>I don&#x27;t know if I agree with this, though:<p>&gt; [T]hese people are suffering terribly, in dire need of help, and when we expend our resources chasing new diagnoses (in the absence of good reason to believe there&#x27;s a new illness), we&#x27;re &quot;validating&quot; them at the expense of actually helping them.<p>Was trying out nasal implants on ENS patients &quot;validating them at the expense of actually helping them&quot;?  Because the implants apparently turned out to help in many cases.<p>And: what constitutes good reason to believe there&#x27;s a new illness?  That&#x27;s a hard question, which I&#x27;m sure can and will be debated forever.  But I think that the condition turning out to respond to a novel treatment -- like nasal implants, in this case -- has to be considered <i>some</i> degree of evidence that there&#x27;s a novel illness.
