Are there any early warning signs of epilepsy?

For seizures. Some are at risk for epilepsy- major head trauma, stroke, brain infection, strong family history are risks. Some get warnings of seizure: funny smells, tastes, abnormal feelings in stomach, shaking of an arm or leg. These may be beginnings of seizures.
See below. Great question. The epilepsy foundation has a good link on that: http://www.Epilepsy.Com/get-help/managing-your-epilepsy/understanding-seizures-and-emergencies/warning-signs-seizures. If you are having seizures, it is recommended you get them evaluated by a neurologist. Driving can be restricted based on the state you reside it, if you have seizures. Hope that answers your question!
