Global cerebral hypoperfusion resulting in syncope, and asynchronous discharge of cerebral
neurons leading to seizure, are two major mechanisms of transient loss of consciousness. They
both have a lot in common in clinical and historical settings, although with a high prevalence of
incorrect diagnosis, even by well-trained staff. The aim of this review was to try to combine data
from both a cardiologist’s and a neurologist’s perspective (history taking, special questionnaires,
serum prolactin, EEG, CT/MRI, tilt-testing, loop recorders). (Cardiol J 2010; 17, 4: 420-427
