Objective:
Motor vehicle accidents direct legislators to ensure pubic safety. We attempted to characterize and quantify driving risk in patients with seizures (PWS).
Methods:
We delivered 12-question surveys to 287 consecutive PWS at an epilepsy clinic in Florida. Illegal and disobedient driving practices were analyzed.
Results:
Eighty-three of 236 (35.2%) PWS were eligible to drive and 62.3% were ineligible with a seizure in <6 months (P<0.001, 95% CI: 0.57-0.70). Among the ineligible responders, 23.8% (35/147) of ineligible responders were illegally driving (14.83% of cohort); 11.86% (28/236) of PWS were disobedient refusing to obey the law, and 8.9% (21/236) of PWS were defiant and knew the law. Sadness (75/236, 31.8%) was the most common reaction to restriction, but disobedient PWS were angry (10/28, 35.7%).
Conclusion:
Overall, a small number of PWS are disobedient and illegally driving. A targeted approach to high-risk drivers with repeated verbal and supplemental driving information may help avoid unnecessary universal physician reporting for PWS.

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
