Autism has been defined basically as a neurological (not mental) condition that  affects children, and is associated with deficits in the areas of socialization, communication, lack of imaginary play (pretend play), and also other factors like sensory issues, and also a high level of anxiety.  Autism can best viewed as a spectrum condition, ranging from profound deficits in some of those areas, to mild manifestations.  Children with severe deficits are usually identified much earlier and receive prompter attention and needed services.  Children with mild manifestation of this condition are usually identified much later, or are usually given a variety of initial diagnosis, the most common of which is usually Attention Deficit Hyperactivity Disorder (ADHD).  This condition is also misdiagnosed when the child presents with a high level of anxiety , as they avoid contact with other children and have very poor eye contact.  For this reason, family history and observation in all settings is a must.  High anxiety, however, is almost present in most children with autism.  This anxiety usually derives from a need to preserve  "sameness" that could be the result of inability to predict people, or could also stem from a variety of sensory "overloads."  

There seems to be a general consensus that autism is the result of dynamic interaction between genes (genome), environment (air, water, food, pesticides, heavy metals,etc) or exposome, and immune system status.  There seems to be many types of autism (phenotypes), and it can not be attributed to a single cause.  It could be explained a result of a "perfect storm" of variables.  There are many factors associated with it, like the pesticide  glyphosate ("round up"), medications (Tylenol), lack of oxygen at birth, maternal stress, cigarette smoking, exposure to emissions from vehicles and chemical factories, use of antibiotics,  C-sections, and lack of breastfeeding , among others.  

Autism has also been defined by some researchers as basically inflammation of the brain.  What could be the sources of such? many substances seem to be involved in this process, like glyphosate ( "Round Up") which is a pesticide widely used in USA and prohibited in Europe.  The involvement of heavy metals including thimerosal (man-made mercury), aluminum, and polysorbate 80, among others.  For more information on this, you could access PUBMed, which is a national collection of scientific information available to all.

Autism and research  

El Autismo ha sido definido por varios investigadores básicamente como una inflamación del cerebro.  Cuales pueden ser las fuentes de ello?  Muchas substancias han sido relacionadas con ese proceso como el glifosato, el cual es un pesticida virtualmente usado ya en todo el mundo, pero prohibido en varios lugares de Europa.  El mercurio, aluminio y otros metales pesados también han sido involucrados.  Para mas información acuda a fuentes científicas como PUDMED, el cual es una colección de escritos de alcance gratuito.    

Treatment of Autism involves a multifaceted intervention involving not only behavioral interventions, but also a full assessment of systems.  What to do first depends on the individualized   assessment of the child.  Recovery is possible, or at least significant improvement in the areas that comprise autism.  Accessing a functional  practitioner is the best way to proceed.  Most medical doctors will treat autistic children symptomatically (will only address symptoms) without accessing the source of the many problems affecting the child.
