Home Videos Show Autism Starts Later in Some
http://my.webmd.com/content/Article/109/109292.htm?z=1728_00000_1000_tn_04"Home videos of children's birthday parties may validate what many parents of autistic children have suspected in retrospect: Children who seemed normal in their first year of life may regress and develop symptoms of autism by their second birthday.
A new study analyzed home videos of first- and second-year birthday parties and showed that some autistic children began displaying symptoms of the disorder by their first birthday, such as less frequent use of words or babbling.
Meanwhile, other autistic children who behaved normally at age 1 appeared to regress and showed typical symptoms of autism by age 2.
Researchers say it's the first objective evidence of autistic regression, a form of autism that accounts for about 25% of all autism cases in the U.S.
..."Very interesting. Any chance we can discuss this without going down the road of possible etiologies? I do have to note that I worked with children and teens with autism whose parents reported similar developments in regard to the onset of autism, starting 15 years ago, which means they were born in the 70s and very early 80s.
