I have begun training a seizure patient at T3 T4 bipolar, rewarding 12-15Hz, inhib 2-13 and 22-38, but since the neurologist did not state where the epileptiform activity was – just said excessive slow wave activity was spotted, I didn’t know whether to move into the SMC or not. The most amplitude in slow wave activity on her TLC Assessment is frontally. Should I move in that direction, or stay away? Since her seizures are infrequent, I may not get any real efficacy information until much later.

Excessive slow wave activity is sort of the bed from which seizures spring, but the seizures themselves are usually very fast activity that " kindles " out from a central point and locks up an area of the brain with highly coherent fast activity. One description I've always liked is that the brain is always sliding back and forth in a fairly narrow band between coma (excessive slow activity) and seizure (excessive fast). Most brains perform this balancing act without much trouble, but when a brain has areas of instability, where it is less able to stay on the high-wire, when if feels itself starting to tumble toward coma, the brain tries to go in the opposite direction and may tumble into seizure. Although many trainers prefer training for seizures in the sensory-motor cortex, that's not necessarily where the seizure focus is. It can be anywhere--often in the temporal lobes. What IS in the sensory-motor cortex is sensorimotor rhythm (SMR). Training SMR, since the early work done by Sterman in the 60's, has been one of the most effective ways of improving seizure activity and making a brain proof against them. However there are other trainings popular as well, including T3/T4 bipolar. Some people, if they know where the focus of the seizures is, prefer to train to activate that area, to make it more stable on the high-wire, and to train up SMR as well.

Guest guest Posted April 19, 2007 Report Share Posted April 19, 2007 Either of the " standard " protools, increasing SMR in the SMC or training across the temporals, are probably pretty good and safe bets.
