My answer to Can you suddenly develop brain disorders or are you only born with them?
Answer by Connie b. Dellobuono:
It takes time for the bug in the gut/intestine to wreak havoc in our brains.
The fetus aborts itself when not complete or lacking in chromosomes. Some mothers who have taken medications/drugs/alcohol or older alcoholic father have children with behavioral health issues.
Nutrition can feed the brain, exercise can stimulate it, and toxic food can inflame it.
