The Center for Disease Control and Prevention (CDC) has developed the Autism and Developmental Disabilities Monitoring Network (ADDM), which is an effort to find the number of people in the United States that have autism spectrum disorders.
There is a significant segment of the autism community that argues that vaccinations are still a possible cause of autism despite the 2009 vaccine court ruling and the discredited 1998 Lancet study, and demand more research into the matter.
Early diagnosis and intervention can make a substantial difference in the future development and abilities of children with autism, so knowing the signs can be the best first step towards helping a child reach his or her greatest potential.
About 33 to 50 percent of all tuberous sclerosis patients have problems such as learning disabilities, severe mental retardation, attention deficit disorder, obsessive-compulsive disorder, autism, aggression, rage, or self-harming behavior.
Some theories about the causes of autism look to environmental factors while others focus on genetics as the source of the developmental disorders, and others see a possible combination of genetic predisposition and environmental triggers.
Those affected by autism can have great difficulty in maintaining eye contact with others, seem indifferent to attempts at interaction from family members and friends, and may resist attempts at physical contact, like hugging or cuddling.
Offering a respite for parents and siblings is a great way to help, caring for the child with autism for an afternoon or weekend to allow some uninterrupted parenting time for other children or much needed adult time for stressed spouses.
Disorders falling under the title of autism spectrum disorder include classic autism, Retts syndrome, Asperger syndrome, childhood disintegrative disorder, and PDD-NOS, which means pervasive developmental disorder not otherwise specified.
Many cite a correlation between the increase in autism cases and the gradual increase in thimerosal exposure as the number of mandatory childhood vaccinations have increased from ten during the 1980s to the thirty that are required today.
While many among this group cite different theories of why this happens, the point of agreement among them is that some or all of the vaccines routinely given during childhood are the cause of much of today's ever increasing autism cases.
