you typically are unaware you are having a seizure (loss of consciousness or sensory hallucinations, etc); not sure if that's the case with panic attacks. I'm guessing panic attacks can involve racing thoughts? With common forms of seizures, you're not really having thoughts at all. feelings of anxiety and panic and racing thoughts can trigger seizures in epileptic tho. If you're not epileptic and you don't have a head injury, you're not likely to randomly have a seizure from anxiety. I'm not a doctor tho, just have epilepsy in the family
