epileptic vs. non-epileptic seizure: what are the signs?

WHAT ARE THE SIGNS?
--review by Avbersek & Sisodiya in J Neurol Neurosurg Psychiatry (link below)
--looked at 34 studies
--tried to tease out what signs distinguish epileptic vs. non-epileptic seizure


WHAT DID THEY FIND?

--signs that favor psychogenic non-epileptic seizures (specificity)
  • fluctuating course (96%)
  • asynchronous movements (93-96%)
  • pelvic thrusting (96-100%)
  • side-to-side head/body movement (96-100%)
  • closed eyes (74-100%)
  • ictal crying (100%)
  • memory recall (96%)

--signs that favor epileptic seizures (specificity)
  • occurance from sleep (100%)
  • post-ictal confusion (88%)
  • stertorous (snoring) breathing (100%)
FYI:
--the sensitivities for all of these signs were horrible, so can't use them to rule anything out
--sometimes excluded frontal lobe partial seizures
--insufficient evidence: gradual onset, flailing/thrasing, opisthotonus, tongue biting, urinary incontinence

  1. My son is diagnosed with epilepsy at the age of 8 years old. During this time, he has only a few hours of sleep over a three-day period. Doctor prescribe him generic lamictal, usually fine for the most part.

    Hi,

    I hope all is well with you. Healthline just published an infographic detailing the effects of epilepsy on the body. This is an interactive chart allowing the reader to pick the side effect they want to learn more about.

    You can see the overview of the report here: http://www.healthline.com/health/epilepsy/effects-on-body

    Our users have found our guide very useful and I thought it would be a great resource for your page: http://add-ed.blogspot.com/2012/05/epileptic-vs-non-epileptic-seizure-what.html

    I would appreciate it if you could review our request and consider adding this visual representation of the effects of epilepsy to your site or sharing it on your social media feeds.

    Please let me know if you have any questions.

    All the best,
