Question?: Pdd Nos Symptoms

George asks…

Poll: Do you think vaccines cause or contribute to autism?

I’m curious to see what people really think.

admin answers:

No i dont believe they do whatsoever! I think parents are just being over cautious and flipping out for no reason. Vaccines have been around for ages, and now they are trying to say that it causes autisim? I dont think so. Dont you think there would have been more causes of that if it was actually linked to the vaccines. Its the same vaccine schedule, its not like the vaccines have changed much in the last 50 years.

Autism and autism spectrum disorders are complex neurodevelopmental disorders.Heritability contributes about 90% of the risk of a child developing autism, but the genetics of autism are complex and typically it is unclear which genes are responsible.Many other causes have been proposed, such as exposure of children to vaccines; these proposals are controversial and the vaccine hypotheses have no convincing scientific evidence.

Autism is a condition involving abnormalities of brain development and behavior which manifests itself before a child is three years old and has a steady course with no remission. It is characterized by impairments in social interaction and communication, as well as restricted and repetitive behavior. It is part of a larger family called the autism spectrum disorders (ASD) or pervasive developmental disorders (PDD), which include closely related syndromes such as Asperger syndrome and PDD-NOS. This article uses autism to denote the classic autistic disorder and ASD to denote the wider family.

Autism’s theory of causation is still incomplete. It has long been presumed that there is a common cause at the genetic, cognitive, and neural levels for autism’s characteristic triad of symptoms. However,here is increasing suspicion among researchers that autism does not have a single cause, but is instead a complex disorder with a set of core aspects that have distinct causes. Although these distinct causes have been hypothesized to often co-occur, it has also been suggested that the correlation between the causes has been exaggerated.The number of people known to have autism has increased dramatically since the 1980s, at least partly due to changes in diagnostic practice; it is unknown whether prevalence has increased as well. An increase in prevalence would suggest directing more attention and funding toward changing environmental factors instead of continuing to focus on genetics.

The consensus among mainstream autism researchers is that genetic factors predominate, but some are concerned, as one anonymous researcher put it, that “geneticists are running the show, and ignoring the environmental aspects.”Environmental factors that have been claimed to contribute to autism or exacerbate its symptoms, or may be important to consider in future research, include certain foods, infectious disease, heavy metals, solvents, diesel exhaust, PCBs, phthalates and phenols used in plastic products, pesticides, brominated flame retardants, alcohol, smoking, illicit drugs, and vaccines. Among these factors, vaccines have attracted much attention, as parents may first become aware of autistic symptoms in their child around the time of a routine vaccination, and parental concern about vaccines has led to a decreasing uptake of childhood immunizations and an increasing likelihood of measles outbreaks. However, as described in Mercury and MMR vaccine below, there is overwhelming scientific evidence showing no causal association between the measles-mumps-rubella vaccine and autism, and there is no scientific evidence that the vaccine preservative thiomersal helps cause autism.

In 2007 the National Institutes of Health announced an Autism Centers of Excellence (ACE) research program to find the causes of autism and identify new treatments for the disorder. Initial recipients are focusing on genetic factors, brain imaging, brain chemicals and functions including mirror neurons, effect on early parent-child behavior on autism, and learning in autistic children.

I am a mother of a 12 month old boy… Who is up to date on all his vaccines so far. And he will continue to get all his vaccinations. As so will any other children i should have. Im sorry but i wouldnt take the risk of my child actually contracting one of those disease just because some parents believe that it may be linked to autisim. Sorry, i would rather have my child vaccinated.

Question?: Rett Syndrome Causes

Jenny asks…

Is sensory processing disorder on the autism spectrum?

I have a 2-year-old who has been diagnosed with Sensory Processing Disorder. One developmental pediatrician said it is “on the spectrum.” Another one said it is not. What is the general consensus out there?

admin answers:

It is not on the spectrum, autism is one of five pervasive developmental disorders (PDD) which is a category of neurological disorders characterized by severe and pervasive impairment in several areas of development. The others included in PDD are Asperger’s Disorder, Childhood Disintegrative Disorder (CDD), Rett’s Disorder, & PDD-Not Otherwise Specified (PDD-NOS).
Sensory Processing Disorder/Sensory Integration Disorder is a neurological disorder causing difficulties with processing information from the five classic senses; the sense of movement; and/or the positional sense. Sensory Processing Disorder/Sensory Integration Disorder has its own diagnosis, but it can be linked to other neurological conditions, including autism spectrum disorders, attention deficit disorder, dyslexia, developmental dyspraxia, tourette syndrome, multiple sclerosis, speech delays, among other conditions.

Autism Characteristic – Behavior Characteristics of Autism

Autism Characteristic

According to Wikipedia, it is a brain development disorder overly impairs social interaction and communication and causes restricted and repetitive behavior, all starting before a child is three decades old. Autism Characteristic

Another definition states that it is a neurodevelopmental disability, which in normal language is a condition that affects the normal growth of the brain so that the individual has difficulty with day-to-day living. Autism is one of the five pervasive developmental disorders (PDD), which are characterized by widespread abnormalities of social interactions and communication, and severely restricted interests and highly repetitive behavior.

Asperger syndrome is another and is a milder form of autism. The main difference in autism and asperger syndrome is that asperger syndrome has no substantial delay in language development. Autism is defined by a certain set of behaviors, which may or may not be evident in infancy (15 to 24 months). Usually these behaviors will be more obvious during early childhood (24 months to 6 years). The National Institute of Child Health and Human Development (NICHD) lists some behaviors that might indicate further evaluation is recommended. Autism Characteristic

These are:

* Your child does not babble or coo by 12 months

* Does not gesture (point, wave, grasp) by 12 months

* Does not say single words by 16 months

* Does not say two-word phrases on his or her own by 24 months

* Does not want to cuddle or be cuddled Below you will find some of the Characteristic Behaviors that are more obvious in children 24 months and older.

Significant difficulties with social interactions:

* Has difficulty developing relationships with peers

* Lack of interest in playing with other children (prefers being alone)

* Has difficulty making eye contact with others

* Shows little body language or facial expressions when interacting

* Seems uninterested in sharing experiences

* Engages less in give-and-take social interaction with others

* Inability to share with others Speech, language, and communication impairments:

* Lack of conversational reciprocity

* Inability to understand or use facial expressions and body language

* Lack of speech, impaired speech or unusual speech

* Echoes words or phrases (echolalia)

Significant difficulties in the development of play:

* May use only parts of toys

* Lines up or stacks objects

* Obsessive attachment to objects

* Lacks the ability to pretend play Autism Characteristic

Unusual responses to normal environmental sensory stimulation (hypersensitivity or hyposensitivity), involving sight, hearing (auditory), taste, smell, touch (tactile), proprioception and vestibular senses are quite common and prominent in autistic children.
