Dreaming experience as a useful diagnostic clue for syncopal episodes

European Journal of Neurology, 04/28/2011

Chiesa V et al. - Dreaming experience seems to be an additional useful diagnostic clue for syncopal episodes, helping the clinician to differentiate them from seizures.


  • 100 patients were asked with GTCS and diagnosis of idiopathic generalized epilepsy (Group 1) and 100 patients with a certain diagnosis of syncope (Group 2) whether they have never felt the impression of coming out of a dream after the loss of consciousness (GTCS or syncope, respectively).
  • This was to verify the occurrence of dreaming experience after syncope and after generalized tonic-clonic seizures (GTCS) and its diagnostic value in differential diagnosis.


  • In Group 1, nobody referred the dreaming experience, whereas in the syncope group, 19% of patients referred this subjective symptom.
