Lyme disease is causing a lot of these problems in kids. ADD/ADHD and autism. I was bit as a kid and lyme stays in your body and you pass it to you baby when your pregnant. What "Under Our Skin" on YouTube it's an hour 44mins but it explains all of it. Lyme is a spiral bacteria so it can go everywhere through out your body.
Lyme disease is an epidemic right now that the cdc needs to address. 300,000 people are getting it a year. Through blood transfusions, mothers having it and passing it to their kids, and getting a tick bite. I new nothing about it till this year. I went four years up diagnosed and then tested my kids and they also have it. The thing is once you start treating it symptoms and problems go away.
