A multi-"salt" magnesium plus some glutathione antioxidant could temporarily calm some of the noise. Look into trans-cranial ultrasound (low power for 30-90 second sessions once or twice a day separated by at least 4 hours) (but this isn't even beyond trials yet), and Earthing which is stepping out barefoot onto the ground). Then vitamin C to recycle the glutathione, protecting it from its breakdown through its job.<p>All of these therapies would be calming inflammation and oxidative stress (both related to each other and to stray/excess electrical charges in the wrong places or out of control).<p>The magnesium I would use is "Magnesium Breakthrough" by "BIOptimizers" since it contains a large variety of salts. The bio-availability and especially the preferential uptake into specific organs...of Mg seems to be dependent on form, or salt.<p>And MIT students, a few years back, invented Magnesium-Threonate is also of therapeutic use as one possible tool, since it increases synapse density and neuroplasticity. Giving the chance of a brain to basically re-wire itself can be helpful when it is not functioning properly.<p>Lastly, fish oil, not snake oil, is going to help the body make the best membrane-encapsulated neuron bodies so that the brain is shuttling its neurotransmitters (which are basically signaling molecules) in a smooth and balanced functional pattern.<p>Other areas for YOU to RESEARCH before purchasing anything are these two things: Probiotics (like Seed DS-01), and Light. Look for a red and infrared light for winter and even summer use. It modifies the power of mitochondria.

And your kid does need to eat food too, as a base. It might just be that doctors have an inborn instinct to protect their valuable secret knowledge from falling into three wrong hands like a Google algorithm unless you have the right keywords, then you'll be rewarded with the right knowledge. I'd like a conversation of such insights as you might have about this and autism, given the fact that also when I was a child, I felt like I was pretty much just watching the life around me and taking notes, or not developing attention and communicating with kids my age in school or making friends.<p>If you want your kid to talk more but they have autism, maybe introduce from an interest of their's to a conversational style designed to be technical and teach the vocabulary of the thing that they like learning about.
