A full workup for children showing signs of neurodevelopmental issues should include checking for vitamin and nutrient deficiencies, and specifically central B12 deficiency.

“there have been a couple of Publications that have just come out that have now recognized a brand new form of autoimmune B12 deficiency and it targets a protein called cd320 which transports vitamin B12 across the bloodb brain barrier the researchers essentially identified this and PE in people who are having pretty severe neuros psychiatric symptom so symptoms of either neurological disorders or other kinds of disorders but mostly focusing on neurology because theur it's neurologists who have been doing all this work when they first identified this antibody they they took blood from these people's veins just like you would if you were going into a doctor for blood draw the B12 levels are normal everything's normal in the periphery because the person may be consuming enough B12 and it may be getting absorbed fine so they're not anemic they show no signs of B12 deficiency but when the researchers tested their cerebr gr spinal fluid they had almost no B12 in their central nervous system”
