"Autism Spectrum" describes disorders that are often called "pervasive developmental disorders". These include Asperger syndrome, autism, childhood disintegrative disorder and Rett syndrome. Symptoms for these disorders include social deficits, difficulties communicating, repetitive behaviors, stereotyped behaviors and cognitive delays. The difference in the individuals with these disorders are in the severity experienced.
In your search to read more about the symptoms of autism in adults you encountered a lot of sights sponsored and supported by the pharmaceutical industry, who, at present, is quite alarmed that they might lose the battle against autism and Alzheimer's to the alternative medical professions utilizing integrative modalities of care.
One reason people develop the symptoms of Pervasive Developmental Disorders (PDD) is because when they went to their regular doctors for checkups, and blood tests were performed, the doctors and laboratories that did the testing used normal ranges. What's wrong with using 'normal ranges'?
Doctors order blood tests all the time. What the normal range is on the blood test is based on the mean averages of the last 1000 people tested by the lab. But these people are not well and the ranges are too large. A more healthy range is a more narrow range...that is the optimum range. Had the doctors of these patients with alzheimer's, before they had Alzheimer's, told them that their blood values were less than optimal, even though they were barely within clinical ranges of normal, then they could have taken measures to correct these less than optimal blood values. A more stringent range encourages us to take healthy measures before we are stricken with an ailment as distressing as Alzheimer's.
Often people's values fall into the 'normal' range, they are told, "all is well", and yet they feel chronically fatigued, not quite right, have anxiety and depression, or are beginning to have the cognitive symptoms of adult autism and they don't know why...after all the blood test says there is nothing wrong with them. Then one day, John Doe dies of a heart attack and everyone thought he was doing fine.
Blood is a good indicator and in the work I do I use a more narrow range, a more stringent range. I make corrections BEFORE problems progress to a more serious state. With cancer now exceeding cardio-vascular as the major cause of death in the U.S. we have to react preventatively well in advance of major diseases. And with PDD on the rise in our youth and in adults we have to make blood and hair value corrections early enough to prevent changes on deeper levels - do nothing and health gets worse!
Adding a hair analysis to the equation makes good sense. It tells us about many items that are not usually tested in the blood. In the work I do I test for 52 items in the blood and 30 in the hair. The hair can show us which of 18 heavy metals have accumulated in our tissues. These heavy metals may be responsible for PDD and other ailments for which, as of yet, the regular medical profession says they do not know cures.
For those with adult symptoms of autism a urine and stool analysis should be considered as well. Constant depletion of nutrients from the body affects brain function. Heavy metals also have the ability to block chemical reactions in the body thereby depleting vitamin stores and causing the production of free radicals. Free radicals interfere with chemical pathways. The more we are unable to create all the molecules we need for normal function the more we are running on 3 cylinders!
Aluminum has been implicated in alzheimer's. A hair analysis will show aluminum in the hair. The heavy metals and the essentials elements, mostly minerals, that the hair analysis will pick up, are an indication of what the body is trying to get rid of. The body uses hair to deposit unwanted substances. When aluminum is high in the hair it indicates that the body is doing well eliminating the aluminum but it also means that the aluminum shouldn't have been there in the first place.
