Functional symptom

Functional symptom

A functional symptom refers to a medical symptom without an apparent cause (etiology) even after the completion of extensive diagnostic assessments. By default, a functional symptom often is judged to have causes that are neither physical nor physiological, but rather psychological or psychiatric.cite journal |author=Mayou R, Farmer A |title=ABC of psychological medicine: Functional somatic symptoms and syndromes |journal=BMJ |volume=325 |issue=7358 |pages=265–8 |year=2002 |pmid=12153926 |doi= |url=http://bmj.com/cgi/pmidlookup?view=long&pmid=12153926]
