Seizure Assessment and Diagnosis

Pre-Seizure Evaluation

  • The European Society of Cardiology recommends asking about warning signs or auras before the seizure, such as rising sensations in the abdomen, unusual smells, visual changes, or other repetitive sensations 1
  • The American College of Emergency Physicians suggests inquiring about potential triggers including sleep deprivation, alcohol use, medication non-compliance, or emotional stress 3, 4
  • The American College of Emergency Physicians advises questioning about prescribed medications that might lower seizure threshold or illicit substance use 3

Seizure Characteristics and Diagnosis

  • The European Society of Cardiology recommends questioning witnesses about specific movements during the event, including synchronous jerking movements of arms/legs or rigid extension 1
  • The European Society of Cardiology suggests asking if consciousness was lost completely or altered, and whether the patient fell 1
  • The European Society of Cardiology advises inquiring about urinary incontinence or tongue biting, though urinary incontinence alone is not diagnostic 1

Post-Seizure Evaluation and Management

  • The European Society of Cardiology recommends asking how the patient felt upon regaining consciousness, as confusion or sleepiness lasting more than a few minutes suggests epilepsy 1
  • The American College of Emergency Physicians suggests questioning about muscle pains lasting hours or days after the event 1
  • The American College of Emergency Physicians advises asking if this is a first-time seizure or part of a known seizure disorder 6

Medical History and Risk Factors

  • The American College of Emergency Physicians recommends inquiring about history of head trauma, stroke, CNS infections, or other neurological conditions 6
  • The American College of Emergency Physicians suggests asking about recent alcohol use or potential alcohol withdrawal 2
  • The American College of Emergency Physicians advises questioning about metabolic disorders, including diabetes, and current medications, particularly antiepileptic drugs and recent compliance 2, 3, 5

Diagnostic Considerations and Pitfalls

  • The European Society of Cardiology warns against relying solely on urinary incontinence to distinguish epileptic seizures from syncope, as this can occur in both conditions 1
  • The European Society of Cardiology advises remembering that movements can occur during syncope and are often misinterpreted as epileptic seizures 1
  • The European Society of Cardiology suggests being aware that transient ischemic attacks rarely cause true loss of consciousness, and if consciousness is lost without other neurological features, TIA is unlikely 1
  • The American College of Emergency Physicians recommends avoiding diagnosing alcohol withdrawal seizures without excluding other causes, especially in first-time seizures 2, 5
