Re: Eyes open alpha

[Guest guest]

Mark,

Yes, but be aware that there may be some traumatic (for him) experiences covered up with all that alpha. Also some head injuries, as they grow older, shift from delta to unblocked alpha (perhaps back of the head fall).

See if there were any major losses or disruptions earlier in his young life, any falls or head injuries the parent(s) can recall, etc.

Training down EO alpha in the back of the head isn't easy, but it's do-able.

I have an interesting 6 y.o. whose global peak eyes open amplitude is in the 8-10 Hz range at Pz ... about 32 uV. EC at Pz was 38 uV, but at Oz it was 76 uV. This "alpha" may not be slow for his age, but there's plenty of it! His diagnosis is ADHD ... concentration, distractibility, non-compliance are all issues. Is attacking it directly the best way to go?

I'm speechless, thank you very much! Now I need to work on my F7-T3 to see if I may repair my speech again Re: Eyes open alpha

You're not wrong, just not complete. There are two type of damage that can result from head injuries: damage to gray matter (the neuron cell bodies) or matter to white matter (the neuron connective filaments).

Gray matter damage results in loss of neurons, no matter what speed they were firing, in an area. Comparing one site with its mirror site (say, C3 compared with C4) you might see a significant difference in the amplitudes at most or all frequencies, with the low side being the damaged side. It is my understanding that over time many brains can repopulate these areas, so gray-matter injuries can resolve with time.

White matter damage doesn't kill the neurons; it just cuts them off from the rest of the world--like a whole class of high school students all losing their cellphones. With no incoming or outgoing communications, the cell tends to drop to the lowest frequency of the brain--the incommunicado frequency we see in deepest sleep--Delta (and often very low theta. Of course the amplitudes of these frequencies would be HIGHER on the side where the damage occurred. And white matter damage does not heal. I can't find the source now (I'm pretty sure it was Jay Gunkelman), but I learned several years ago that these neurons over time can tend to shift up into the low alpha frequency, resulting in high amplitudes of 8-10 Hz instead of Delta.

please correct me if I'm wrong, to consider a head injury in most cases the Delta and Theta could be higher than normal, especially with EO comparing to EC, is this true? I'm asking because you mentioned that greater alpha in the back of the head, specially in this case (6 y.o.) could be related to a TBI, I don't understand that.
