                                           The "Causes" of Autism



    CAUSES (from Autism Speaks)

    One of the most common questions asked after a diagnosis of autism, is what caused the
    disorder. We know that there’s no one cause of autism. Research suggests that autism develops
    from a combination of genetic and nongenetic, or environmental, influences. These influences
    appear to increase the risk that a child will develop autism. However, it’s important to keep in
    mind that increased risk is not the same as cause. For example, some gene changes associated
    with autism can also be found in people who don’t have the disorder. Similarly, not everyone
    exposed to an environmental risk factor for autism will develop the disorder. In fact,
    most will not.

    Autism’s genetic risk factors
    Research tells us that autism tends to run in families. Changes in certain genes increase the risk
    that a child will develop autism. If a parent carries one or more of these gene changes, they may
    get passed to a child (even if the parent does not have autism). Other times, these genetic
    changes arise spontaneously in an early embryo or the sperm and/or egg that combine to create
    the embryo. Again, the majority of these gene changes do not cause autism by themselves.
    They  imply increase risk for the disorder

    Autism’s environmental risk factors
    Research also shows that certain environmental influences may further increase – or reduce
    – autism  risk in people who are genetically predisposed to the disorder. Importantly, the
    increase or decrease in risk appears to be small for any one of these risk factors:

    Increased risk
    Advanced parent age (either parent)
    Pregnancy and birth complications (e.g. extreme prematurity [before 26 weeks], low birth
    weight,
    multiple pregnancies [twin, triplet, etc.])
    Pregnancies spaced less than one year apart

    Decreased risk
    Prenatal vitamins containing folic acid, before and at conception and through pregnancy
    No effect on risk.

    Vaccines. Each family has a unique experience with an autism diagnosis, and for some it
    corresponds with the timing of their child’s vaccinations. At the same time, scientists have
    conducted extensive research over the last two decades to determine whether there is any
    link between childhood vaccinations and autism. The results of this research is clear: Vaccines
    do not cause autism. The American Academy of Pediatrics has compiled a comprehensive list
    of this research.

    Differences in brain biology
    How do these genetic and nongenetic influences give rise to autism? Most appear to affect
    crucial aspects of early brain development. Some appear to affect how brain nerve cells, or
    neurons, communicate with each other. Others appear to affect how entire regions of the
    brain communicate with each other. Research continues to explore these differences with an
    eye to developing treatments  and supports that can improve quality of life.

    Asperger syndrome, or Asperger’s, is a previously used diagnosis on the autism spectrum.
    In 2013, it became part of one umbrella diagnosis of autism spectrum disorder (ASD) in the
    Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5).

    Though the diagnosis of Asperger syndrome is no longer used, many previously diagnosed
    people still identify strongly and positively with being an “Aspie.”

    Therapies:
    * Cognitive behavioral therapy can help address anxiety and other personal challenges.
    * Social skills training classes can help with conversational skills and understanding social cues.
    * Speech therapy can help with voice control.
    * Physical and occupational therapy can improve coordination.
    * Psychoactive medicines can help manage associated anxiety, depression and attention deficit
      and hyperactivity disorder (ADHD).

    How has our understanding evolved?

    1944: Austrian pediatrician Hans Asperger described four strikingly similar young patients.
    They had normal to high intelligence. But they lacked social skills and had extremely narrow
    interests. The children also shared a tendency to be clumsy.

    1981: British psychiatrist Lorna Wing published a series of similar case studies. In it, she coined
    the term “Asperger syndrome.”

    1994: Asperger syndrome listed in the Diagnostic and Statistical Manual of Mental
    Disorders (DSM-4).

    2003: Asperger syndrome and other previously separate types of autism folded into
    one umbrella diagnosis of “autism spectrum disorder” in DSM-5.

    Can autism develop (vs show up) later?
    Some children show signs from birth. Others seem to develop normally at first, only to suddenly
    show symptoms when they are 18 to 36 months old. However, it is now recognized that some
    individuals may not show symptoms of a communication disorder until demands of the environment
    exceed their capabilities.

    Can you suddenly become autistic?
    In the case of high-functioning autism, for example, it's not unusual for a child (or even an adult) to
    receive a diagnosis much later than most children are diagnosed with autism—but that's not because
    symptoms suddenly developed.

    Do autistic toddlers smile & laugh?
    A child at risk for autism may not smile or laugh in response to your smile or playfulness although
    he/she may smile at you on their own and look very happy.
