Of these rare neurological dysfunctions, Autism is the most common of these passive developmental disorders. Autism is a disability caused by a brain development disorder of unknown cause, yet some suspect the cause is some sort of neurological dysfunction- possibly with a genetic predisposition.
Usually, symptoms of the disease present themselves before the toddler reaches the age of three. Before Autism was more understood, others inaccurately labeled autistics as childhood schizophrenia or as having a psychosis or mental retardation.
Out of over two dozen diagnostic criteria utilized for these disorders, eight must be present to be considered autistic, according to the DSM. As with all passive developmental disorders, the person expresses language, social, and behavioral difficulties.
Treatment includes what are called psychotropic medications that delay the progression of the disorder, as well as relieve some of the symptoms of one who is autistic. Behavioral therapy is common as a treatment regimen as well. Boys get Autism much more than girls.
Then there is the controversy between many who claim that thimerosal- a preservative containing mercury, which is a neurotoxin that was used in vaccines until 2001, was the catalyst for autism in children.
Over 5000 lawsuits have been filed because of this belief, and some have been successful for the plaintiff. Yet most agree the correlation between thimersal and autism is void of scientific merit. Furthermore, the cases of autism have not decreased since the preservative was discontinued in 2001.
Aside from Autism, the other four passive developmental disorders are known as autism spectrum disorders.
Asperger’s Syndrome is more common than autism, and the symptoms are milder, as there is minimal delay in language abilities, if at all. What is expressed with Asperger’s syndrome is mild autistic symptoms. In time, the patient may express atypical personality disorders, though.
While intelligence is within normal limits with the Asperger’s patient, social interactions and abilities preset difficulty for such a patient. As with Autism, medications and behavioral therapy are treatment regimens with one with this syndrome
Rett’s Syndrome or disorder presents with not only atypical behavior, but also suffers from restricted physical growth and movement.
There is cognitive and social impairment as well. The disorder affects mostly girls, and the cause is due to a gene mutation.
Childhood Disintegrative disorder is rare, and is 10 times less common than autism. The disorder has a late onset with mild autistic symptoms. The disorder affects mostly boys, and regression is sudden and possible with this disorder.
Skills lost with this disorder may be language, social, self-care, as well as play or motor skills. Decreased function or impairment with this disorder may include social skills and behavioral flaws. Central Nervous System pathology is a suspected cause of this disorder.
Finally, there are passive development disorders that are not otherwise specified. This may include atypical autism, for example. Yet as with the rest of types of these disorders, the symptoms vary in their frequency and intensity, as well as the range of abilities of these developmental disorders vary widely as well.
Medicinal treatment along with cognitive and behavioral therapy prove to be most beneficial for all the different types of Passive Development Disorders that unfortunately exist for unknown reasons, yet further research should be done to discover both the etiologies as well as more effective treatment for the Autism Spectrum.
