As with other areas of medicine, there is no substitute for a careful diagnostic evaluation using externally validated diagnostic criteria. Whenever possible, the diagnostic evaluation should draw on a comprehensive database that includes family members, previous or concurrent providers, and other sources of information, and the evaluation should focus more on longitudinal data than just acute presentation.
