Dizziness, vertigo and presyncope may be confused with syncope but these conditions do not cause loss of consciousness.

Syncope may resemble epileptic seizures but certain features in a history would favour syncope:

  • precipitants such as pain, micturition, defaecation and emotion
  • associated symptoms such as sweating and nausea
  • rapid recovery without signigicant confusion

Jerking movements suggest seizure but they may occur in syncope.

Syncope falls within the broader subject area of attacks of loss of consciousness.
