Behavior Symptoms Checklist For Kids With Autism

Behavior Symptoms Checklist For Kids With Autism

Julie: A worried mom can do better research than the FBI. Or at least, that’s what they say. This mom shares some of her research and I have found it a great starting point for helping my kids through health challenges even though they don’t have autism. You might notice a commonly reoccurring theme – vitamin deficiency. This is for educational purpose and not intended to treat or diagnose.

Symptom Check

I have listed some of the common symptoms/behaviors that autistic children experience below, and some of the reasons that these symptoms may be occurring.  This list is not comprehensive nor conclusive.  The information provided is for educational purposes only.
