What is the likelyhood I will have another seizure?

Okay, so back in May I took some Benedryl to help me sleep as I had not been sleeping well for several days. Shortly after I took the Benedryl I had a grand mal/tonic clonic/generalized (?) seizure and was unconscious for several days. While I was out they took an MRI or CAT scan or whatever it is of my brain to rule out brain tumors (which I knew it wasn't).

In 2007 I was diagnosed with Asperger's Syndrome, and in 2009 I was haphazardly diagnosed with myoclonus, but I stopped seeing the neurologist because I got the impression he didn't think my case was very interesting. That and he kept pushing meds.

Since May I am not 100% positive that I haven't had any seizures. I say 100% because I had a very strange dream back in September that I was having a seizure at the doctors office (the doctor said it was an absence seizure) and when I woke up I was very tired, confused, and slightly dizzy.

The more I read about seizures the more I wonder if I have had seizures before May. Anyway, what do you think is the possibility that I will have one or more seizures? I know people with Autism are more likely to have seizures...

So you think I have a 50/50 chance of having another seizure?

Hello,

Before I start, I must inform you that I am a private researcher and NOT a licensed doctor, do not construe anything I tell you as medical advice.

Benadryl, or Diphenhydramine, is an antihistamine drug  which is an H1 receptor antagonist. In people who are epileptic or otherwise prone to seizures, this drug usually causes a seizure because its mechanism of action reduces the seizure threshold.

Alot of people just have one seizure and never have another, in your case it appears to have been provoked by the drug. I would consult a neurologist.
