Red and white cubes

Had to take a mental examination for epilepsy on Monday morning. Lots of drawing, writing things down, repeating, remembering, trying to do things backwards. Little brain games. I was doing OK until the cubes. Four of them, red on some sides, white on other sides, some 50/50. I had to put them in combinations to create patterns. Right off the bat I knew I was in trouble…I had to create abstract patterns with abstract patterns. A trigger. I don’t do abstract shapes well. Within seconds I was going numb, talking slow, having trouble remembering anything. But I finished the test. All day long I was in a daze. Memory problems, out of it. Next day the same thing. On Wednesday more of the same. Finally today I am mostly back to normal. It used to be that concentrating on abstractions like that would wipe me out for a few hours. Now it lasts days. It’s not as intense as it used to get–no nausea–but it’s longer lasting. And of course, all that does is burn out more synapses and wreck more neurons. It’s like an epilepsy loop. The damage causes aka petit mal seizures which wrecks neurons which causes petit mal seizures which wrecks more neurons…..drip drip drip.

I’ve been trying to write this for days now. But I had to write this without trying to visualize the cubes and patterns, as the memory of them has the same effect as the actual experience, though the symptoms–numbness, stutter, memory loss–were even stronger. Apparently the actual experience of playing with those damn cubes involved several disparate sensory parts of the brain, but the memory involves only the parts of the brain that store the memories of the experience, and for some reason those memory centers set off more of the symptoms than the original sensory centers. If I were to think hard right now and try to remember actually doing the tests–though the memory of it is thoroughly garbled by now–I would actually get sicker than if I were actually doing the tests. I suppose I was only able to write this now as the short term memory of it has dissipated…as short term memories do after a couple days. Medium and long term memories are not as triggerable, if that is a word. If not, it is now.

The focal point of my seizures is a hole in the brain in the frontal lobe. A birth defect. Hence I can be set off by certain abstractions. I cannot do any sort of math beyond simple mathematics, I cannot read complex philosophy, I have difficulty with the modularity of things within things within things. Were I a gorilla (a common misconception, actually), this would not be as much of a problem. But Homo sapien sapiens are really big on the abstractions; our brains, in large part, grew huge because of the giant frontal lobes that developed to handle abstractions. It’s just that some of us have holes in our frontal lobes. Most of my symptoms, however, are in the temporal lobe, as so much frontal lobe activity is channeled through the temporal lobe. When the neurons that are all screwed up around the hole in my brain in my frontal lobe start firing in too rapid an order and messing things up, the extra electrical energy is released in the temporal lobe. Apparently the frontal lobe can handle such things easier. The temporal lobe, perhaps because it is much older and developed when brains were smaller and contained far less potential electrical energy (think of a neuron as a battery, and our frontal lobes are an enormous collection of interconnected batteries), perhaps never developed the protection it needs to protect it from such excess electricity. Like putting a Model T electrical system in a Porsche. The slightest thing could burn it out. And after a lifetime of epilepsy, the temporal lobe is thoroughly burned out. It has actually shrunk in size from all the electrical abuse, and a wide array of its knowledge–the various kinds of memories it stores in various places–are not even accessible anymore. The executive functions it controls–planning, etc–get thoroughly messed up. Frontal lobe functions–all that useless historical information and irritating know-it-all trivia–are unfazed. I can write. I can read. I can talk and talk and talk until everybody leaves. But stupid things like red and white cubes can mess me up for days.

One of the fun things about epilepsy is how it displays the inner workings of the brain. If you are fascinated by cognitive processes, it’s like being your own laboratory. One of the less fun things is drooling all over the carpet.
