It would kinda make sense autism and ADD would be contributed to some sort of brain malnutrition. There are all sorts of Vitamin B which is essential for normal brain health. One of the things that depletes Vitamin B(s) is too much sugar in your diet and/or alcohol consumption. Vitamin B deficiency is also linked to poor diet, obesity, drug use, smoking, drinking heavily, even too much screen time on your smartphone and/or playing too many video games/tv time.

If you have children with autism you should be giving them Vitamin B complex (a supplement that is loaded with all the most essential Vitamin Bs for brain health). You can also 'detox' their kidneys, liver and brain with a common safe household product known as Baking Soda (aka Arm & Hammer, or otherwise known as sodium bicarbonate). Take a teaspoon of sodium bicarbonate and a 16oz glass of water, dissolve it into the water by stiring it in for a couple minutes, wait till it fully dissolves and have your kid drink it. You should do this every other day or at least three times a week. The sodium bicarbonate helps detox your organs from heavy metals, toxic chemicals often found in tap water and mass produced foods and helps reduce unhealthy acidity in the body.

The medical industrial complex has done everything they can to cover these common cheap old tricks up because if people learned the truth they wouldn't be making so much money.
