MediumNeurologyDifferentiating seizure from syncopeau-amc
A 26-year-old woman presents after a witnessed collapse. A friend describes stiffening followed by rhythmic jerking of all limbs for 2 minutes, tongue biting and urinary incontinence. She was confused for 20 minutes afterwards. She has no prior history of seizures. CT brain is normal and routine blood tests are normal. Which feature most strongly supports an epileptic generalised tonic-clonic seizure rather than syncope?
