Autism and autism spectrum disorders are far FAR more complicated than just a two year olds simple fascination with wheels - 2 year olds are supposed to be fascinated with things that seem boring and typical to us because THEY are just experiencing and understanding them for the first time. Just like it is normal for a two year old to open and close a drawer or kitchen cabinet a thousand times as he learns how and why it works, it is normal for a young child to be deeply fascinated with the most common of objects because that is how we build our knowledge about how and why the world, and things in it, work the way they do. If your child had autism, his fascination with wheels would not even register on your list of abnormal behaviors.
I have worked with children and adults with autism for 8 years, and it is generally well agreed upon between the professionals that work with them (occupational therapists, physical therapists, speech therapists, teachers, music and art therapists) that vaccinations are not THE cause of autism. There are hundreds and thousands of other factors that have to be factored in when diagnosing and treating the disease, but parents will grab at straws in their search to find someone or someTHING to blame for their child's debilitating condition that can literally tear families, friendships, and communities apart. It is no coincedence that, in a family that already as a child with autism, PDD, or is on the autistic spectrum, the chance of those people having subsequent children with developmental disabilities is much higher than in those families with no history of autism or like disorders. There is a very clear genetic link, but many parents find comfort in denying that reality and focusing on a more "real", changeable cause like autism being caused by vaccinations.
I could go on forever about this, but I would like to give you a REAL, working list of symptoms of autism in infants and young children that are required in order for a diagnosis:
Signs of autism may appear during infancy and the disorder is usually diagnosed by the age of 3. Sometimes the child's development appears normal until about 2 years old and then regresses rapidly. Symptoms of autism occur in various combinations, from mild to severe.
Infants with the disorder often display abnormal reactions to sensory stimuli (i.e., senses may be over- or underactive). Touches may be experienced as painful, smells may be overwhelmingly unpleasant, and ordinary daily noises may be painful. Loud noises (e.g., motorcycle going by, vacuum cleaner) and bright lights may cause inconsolable crying.
Other signs of the disorder in infants include the following:
Appears indifferent to surroundings
Appears content to be alone, happier to play alone
Displays lack of interest in toys
Displays lack of response to others
Does not point out objects of interest to others (called protodeclarative pointing)
Marked reduction or increase in activity level
Resists cuddling
Young children with autism usually have impaired language development. They often have difficulty expressing needs (i.e., use gestures instead of words) and may laugh, cry, or show distress for unknown reasons. Some autistic patients develop rudimentary language skills that do not serve as an effective form of communication. They may develop abnormal patterns of speech that lack intonation and expression and may repeat words or phrases repetitively (called echolalia). Some children with autism learn to read.Autistic children do not express interest in other people and often prefer to be alone. They may resist changes in their routine, repeat actions (e.g., turn in circles, flap their arms) over and over, and engage in self-injurious behavior (e.g., bite or scratch themselves, bang their head).
Other symptoms in young children include the following:
Avoids cuddling or touching
Frequent behavioral outbursts, tantrums
Inappropriate attachments to objects
Maintains little or no eye contact
Over- or undersensitivity to pain, no fear of danger
Sustained abnormal play
Uneven motor skills
Unresponsiveness to normal teaching methods and verbal clues (may appear to be deaf despite normal hearing)
Symptoms of autism may increase in severity when the child enters adolescence and often decrease in severity during adulthood.
