Major Areas of Research in Autism:

1) Digestion- Related

2) Food & Nutrition-Related

3) Immunity-Related

4) Environmental Toxicity-Related

1) Digestion-Related Autism Research:

I have found that intestinal dysfunction in children with ASD is associated with increased irritability, tantrums, aggressive behaviour, and sleep disturbances.  Seventy percent of children with autism have intestinal symptoms, and many have a “leaky” intestinal lining, which leads to intestinal and immune dysfunction.  Micro-organisms in the intestines can be out of balance, and in keeping with the “Bacterial Theory” of Autism, it is important to put the intestinal microbial environment back into balance, in addition to restoring proper digestion and absorption.

2) Food and Nutrition-Related Autism Research:

Specific nutrients are fundamental for proper neurodevelopment and immune function.  I often find that when the ASD child’s specific nutrient deficiencies or insufficiencies are corrected, a number of benefits can manifest quite quickly, and other therapies generate more effective responses.  Note emerging nutrition-related theories of Autism including the “Vitamin D Theory.”

3) Immunity-Related Autism Research:4) Environmental Toxicity-Related Autism Research:

The immune system plays a large role in the self-regulatory functions of the whole body, and affects and connects everything in the body, including the digestion, nervous system, and can have cognitive-behavioural and developmental impact.  Auto-immunity and inflammation can be important factors to address, and can be useful indicators to track.

4) Environmental Toxicity-Related

Increased immune reactivity and sensitivity to even residential/domestic pollutants can affect cognitive-behavioural development.  Infants and toddlers may also be neurologically sensitive to medications and their by-products, such as from acetaminophen/paracetamol. Testing and addressing chemical exposures can be useful in the care of ASD children.  Options for fever and pain management are also important.
