  • Tonic-Clonic Seizure

    During a police chase on foot, a previously well police officer was hit mistakenly by a taser shot meant for the suspect. The taser gun had been fired once, sending 2 barbed darts into his upper back and occiput. Within seconds, the officer collapsed and experienced a generalized tonic-clonic seizure with loss of[…][ncbi.nlm.nih.gov]

Half of the patients have these abnormalities only in sleep. Caution.[medlink.com]
