Syncope is common and has been defined as transient loss of consciousness, associated with inability to maintain postural tone and with immediate, spontaneous and complete recovery. Patients presenting with transient loss of consciousness due to neurological causes (such as seizures and stroke) are infrequent and must be differentiated from true syncope. While neurological disorders can occasionally result in transient loss of consciousness, the utility of neuro-imaging studies are of limited benefit in the absence of signs or symptoms concerning for neurological pathologies.
