I was just diagnosed with temporal lobe epilepsy. In retrospect, I had dozens of simple partial seizures in the months (couple of years) before I was diagnosed and treated. I didn’t get a chance to ask about this when I last saw my neurologist. In general (I’m not asking for specific medical advice, see), is there a risk to someone’s cognition from repeated seizures? Even if they’re “just” simple partial ones?
Too variable to say, if I have my information correct. I hasten to add I Am Not A Doctor, but from what I’ve heard over the years epilepsy can “impact cognition” but does not necessarily do so. The better controlled seizures are the less likely they are do cause that kind of damage, but you really can’t say because there are people with relatively frequent seizures and apparently normal cognition, and some with severely impaired cognition and mild seizures. It really is something that varies widely with the individual.
Of course, if a neurologist shows up and says differently go with that - always trust a real MD over a random layperson on the internet. 
Here’s a nice review article on epilepsy and cognition.
In short, yes it can, and often does. But it depends.
I’d like to add that directly after a seizure there is a phase most go through. The postictal state is the altered state of consciousness that a person enters after experiencing an epileptic seizure, such as those occurring with frontal lobe epilepsy. It usually lasts between 5 and 30 minutes, but sometimes longer in the case of larger or more severe seizures and is characterized by drowsiness, confusion, nausea, hypertension, headache or migraine and other disorienting symptoms. Additionally, emergence from this period is often accompanied by amnesia or other memory defects. It is during this period that the brain recovers from the trauma of the seizure.
:(. That’s… very upsetting. I like my cognition.
Quoted from that article:
The article claims some studies find cognitive improvement after being diagnosed with epilepsy, which could possibly be caused by the treatment. That would indicate epilepsy can affect cognition in a statistically significant number of people. Not all studies examined in the article found this result, though.
Also, keep in mind that “epilepsy” isn’t a real diagnosis. It’s a term that covers a huge variety of conditions, and some of those conditions also involve cognitive impairment. This means that studies which examine cognitive deficiency in people with epilepsy might find a correlation between the two, but that doesn’t mean the epilepsy CAUSES the cognitive decline. The two are just symptoms of the same disorder.
Hang in there! In my layman’s opinion, I think you’ll continue to be the same jerk you always were 
(kidding in case that wasn’t clear)
I do want to point out that cognition problems do not necessarily mean you’ll become stupid. And it does not necessarily include personality changes.
True enough. What worries me is that they show higher risk of cognitive decline in cortical dysplasia, and my grey-matter heterotopy is an example of that.
On the other hand, your proper use of several polysyllabic words in that post make me think your cognition is functioning rather well.
I get that sometimes I fall on the floor and then think that I’m dying it goes away thats a good thing to know.
