Autism is a complex developmental disability that results in problems with social interaction. These symptoms normally appear before the age of three. Early intervention is critical to the child’s future well being.
What We Know
Autism is a developmental disability that is a brain-based, neurological condition. It is part of the family called Autism Spectrum Disorders, or Pervasive Development Disorders (PDDs). Autism is usually diagnosed before the age of three, and is diagnosed four times as often in boys than in girls. Statistics show that 1 in 166 children are diagnosed with an autism spectrum disorder. This number has grown significantly over the last three decades. It is the fastest growing developmental disability with an annual growth of 10-17%.
What We Don’t Know
Each case of autism proves to have a different pattern. Autism is biologically based, but its exact cause is still a mystery. Autistic children have a genetic make-up that leaves them predisposed to autism, making them susceptible to a wide variety of triggers. It is here that the mystery lies. Researchers cannot pinpoint an exact trigger. There is also debate on whether there is one cause for autism. Some scientists feel that there is only one cause, while others feel that autism has multiple causes.
Despite all of the questions and uncertainty, because of the dramatic rise in autism cases it will continue to be on the forefront of research. This is leading advocates to push for increased funding for research into autism and other neurological conditions. New techniques for studying the brain may lead researchers to answers that could help improve treatments and interventions.
