VITAMINS AND SUPPLEMENTS:

Research shows that many individuals with autism spectrum disorders have vitamin and mineral deficiencies.  One possible cause could be sensory integration dysfunction, which may cause one to self impose a limited diet which in turn effects biochemistry. Correcting this imbalance is the key to healing some of the symptoms of autism. 

Dr. Jacquelyn McCandless, a practicing DAN doctor, has written a book called Children with Starving Brains, an excellent source of information for various treatments used by DAN practitioners.
