In the evaluation of simple syncope and a normal neurologic examination don’t obtain brain imaging studies (CT or MRI).

Website maintenance is planned from 8:00 a.m. CDT Saturday, July 27, through 9:00 p.m. CDT Sunday, July 28. Brief disruptions may occur during this time.

Rationale and Comments

In patients with witnessed syncope, but with no suggestion of seizure and no report of other neurologic symptoms or signs, the likelihood of a central nervous system cause of the event is extremely low and patient outcomes are not improved with brain imaging studies.
