Epilepsy And Memory
Memory, then & now
Or a new dessert - from that same night.For the first time, scientists have recorded traces in the brain of that kind of contextual memory, the ever-shifting kaleidoscope of thoughts and emotions that surrounds every piece of newly learned information. The recordings, taken from the brains of people awaiting surgery for epilepsy, suggest that new memories of even abstract facts - an Italian verb, for example - are encoded in a brain-cell firing sequence that also contains information about what else was happening during and just before the memory was formed, whether a tropical daydream or frustration with the Mets.
Video of things past
The new study suggests that memory is like a streaming video that is bookmarked, both consciously and subconsciously, by facts, scenes, characters and thoughts. Experts cautioned that the new report falls well short of revealing how contextual memory and different cues interact; some words might throw the mind into a vivid reverie, while others do not. But the report does provide a glimpse into how the brain places memories in space and time.
"It's a demonstration of this very cool idea that you have remnants of previous thoughts still rattling around in your head, and you bind the representation of what's happening now to the fading embers of those old thoughts," said Ken Norman, a neuroscientist at Princeton who did not participate in the study. "I think they have very good evidence that this process is crucial to time-stamping your memories."
In the new study, in the current issue of the journal PNAS (Proceedings of the National Academy of Sciences), doctors from the University of Pennsylvania and Vanderbilt University took recordings from tiny electrodes implanted in the brains of 69 people with severe epilepsy. The implants are standard procedure in such cases, allowing doctors to pinpoint the location of the flash floods of brain activity that cause epileptic seizures.
The patients performed a simple memory task. They watched a series of nouns appear on a computer screen, one after another, and after a brief distraction recalled as many of the words as they could, in any order. Repeated trials, with different lists of words, showed a predictable effect: The participants tended to remember the words in clusters, beginning with one and recalling those that were just before or after.
This pattern, which scientists call the contiguity effect, is similar to what often happens in the card game concentration, in which players try to identify pairs in a grid of cards lying face-down. Pairs overturned close in time are often remembered together.

Memory Loss - after sezuire | epilepsy.com
Hello,
I am only new to this site, I have had epilepsy for over a year I am 19 years old, the sezuires started as grand mal sezuires and this continued for most of the year, they became more and more frequent before I started my medication I was having at least 2 or 3 a week. I started medication and have been on it for just over 6 months, every thing was going pretty well, I had one sezuire a few months after starting and then up until 2 weeks ago I have been fine. My concern is to do with the last sezuire I had. Basically, it wasnt really a 'normal' sezuire. I dont remember clearly anything that happended in the day. I have been told that I didnt blackout or have a sezuire as I would normally have, but I just forgot who I was, where I was and everyone and everything. This lasted for over 3 hours. I didnt know who my boyfriend of three years was and I fought him off me when he tried to help, I didnt even remember my mums name until 2 hours after it started. I am really worried and scared that it might happen again. I just want to know if anyone else has experience this or knows any thing about it. Thanks so much.
