What is Autism

Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. They include autistic disorder, Rett syndrome, childhood disintegrative disorder, pervasive developmental disorder-not otherwise specified (PDD-NOS) and Asperger syndrome. ASD can be associated with intellectual disability, difficulties in motor coordination and attention and physical health issues such as sleep and gastrointestinal disturbances. Some persons with ASD excel in visual skills, music, math and art.

Autism appears to have its roots in very early brain development. However, the most obvious signs of autism and symptoms of autism tend to emerge between 2 and 3 years of age.  If your child is diagnosed with autism, early intervention is critical to gain maximum benefit from existing therapies. Although parents may have concerns about labeling a toddler as “autistic,” the earlier the diagnosis is made, the earlier interventions can begin. As soon as autism is diagnosed, early-intervention instruction should begin. Effective programs focus on developing communication, social, and cognitive skills.
Autism was first identified in 1943 by Dr. Leo Kanner of Johns Hopkins Hospital. At the same time, a German scientist, Dr. Hans Asperger, described a milder form of the disorder that is now known as Asperger Syndrome. These two disorders are listed in the DSM IV (Diagnostic and Statistical Manual of Mental Disorders) as two of the five developmental disorders that fall under the autism spectrum disorders. The others are Rett Syndrome, PDD NOS (Pervasive Developmental Disorder), and Childhood Disintegrative Disorder. All of these disorders are characterized by varying degrees of impairment in communication skills and social abilities, and also by repetitive behaviors.
How Common is Autism?
Autism statistics from the U.S. Centers for Disease Control and Prevention (CDC) identify around 1 in 88 children is diagnosed with autism – a ten-fold increase in prevalence in 40 years. Studies also show that autism is three to four times more common among boys than girls. Current estimates are that in the United States alone, 1 out of 54 boys and 1 in 252 girls are diagnosed with autism.  There is no established explanation for this continuing increase, although improved diagnosis and environmental influences are two reasons often considered.
ASD affects over 2 million individuals in the U.S. and tens of millions worldwide. Moreover, government autism statistics suggest that prevalence rates have increased 10 to 17 percent annually in recent years.  By way of comparison, this is more children than are affected by diabetes, AIDS, cancer, cerebral palsy, cystic fibrosis, muscular dystrophy or Down syndrome, combined.

    Attended Fan the Flame at NWEFC in Burnaby last night. Wow. Wonderful. And I learned some things about autism too. My diagnosis of suffering is (chronic) schizophrenia. I read two books about intellectual disabilities this year. One old from (entitled “The Idiot” by a medical doctor in the late 1800s) and one from open bccampus or some such keyword search which is a new and helpful psychiatric nursing text. Both are free downloads. The book I mentioned at the meeting was “Idols of Our Time” by Bob Goudzwaard (1984) and he has done things since then. The idols were: revolution, nation, security, and prosperity or so it seems (I do not recall well). The new book is: Supporting-individuals-with-intellectual-disabilities-and-mental-illness though I do not know if that will lead to the website. Thanks.

    Sorry, too little information (really). “The Idiot” is a second edition from 1897 by Frederic Bateman. The thing of note with the book is that he (the author) wants an ever better future for people with intellectual disabilities. It is interesting for an old book. The slogan of “Excelsior” on page 104 is especially inspiring. Much is about recovery. And beyond perhaps too.
