title: Pattern recognition as a guide in diagnosing headache.
abstract: This paper presents the family physician with a comprehensive yet simple classification that is easily followed. By a system known as 'pattern recognition', the physician may determine cause in the majority of headaches in his own office. With use of ancillary investigatory procedures where necessary, he will refer only when the diagnosis warrants it.
