Learn to Think Better: Tips from a Savant: Scientific American - 0 views

  • Daniel Tammet is author of two books, Born on a Blue Day and Embracing the Wide Sky, the latter of which came out in January. He is also a linguist and holds the European record for reciting the first 22,514 digits of the mathematical constant pi.
  • When I was a child, my behavior was far from being what most people would label “intelligent.” It was often limited, repetitive and antisocial.
  • I could not do many of the things that most people take for granted, such as looking someone in the eye or deciphering a person’s body language, and only acquired these skills with much effort over time. I also struggled to learn many of the techniques for spelling or doing sums taught in class because they did not match my own style of thinking.

A Family United For The Autistic: 15 Yr Old Aspie Talks About Autism - 0 views

  • Autism gives many unique traits to an individual, and many of these people go on to do great things (it is said Isaac Newton, Albert Einstein, Bill Gates, and other innovators and scientists had forms of autism). I can’t speak for others - maybe they do want to rid themselves of their condition. But as for the parents and individuals making the decision, think about it: do you honestly want a cure that is going to change the individual you are?

Entrepreneur Thorkil Sonne on what you can learn from employees with autism - HBR.org - 0 views

  • So he went out on his own and launched Specialisterne, a Copenhagen-based software-testing firm that now has 51 employees, including 37 with autism, and revenues of $2 million.
  • Most of our consultants with autism have a mild form called Asperger’s and are high functioning.
  • I think normality is whatever the majority decides it will be, and in our company people with autism are the norm.

Asperger Syndrome Tied to Low Cortisol Levels - 0 views

  • Low levels of a stress hormone may be responsible for the obsession with routine and dislike for new experiences common in children with a certain type of autism.
  • The body produces cortisol, among other hormones, in stressful situations. Cortisol increases blood pressure and blood sugar levels, among other duties, to signal the body's need to adapt to changes occurring around it.
  • People with Asperger syndrome notably have very repetitive or narrow patterns of thought and behavior, such as being obsessed with either a single object or topic. Though tending to become experts in this limited domain, they have otherwise very limited social skills, according to the study.

  • "Although these are early days, we think this difference in stress hormone levels could be really significant in explaining why children with AS are less able to react and cope with unexpected change,"
  • If these Asperger symptoms are caused primarily by stress, caregivers could learn to steer children away from situations that would add to anxiety, the researchers said.
  • "This study suggests that children with AS may not adjust normally to the challenge of a new environment on waking,"
  • The researchers, whose findings were published in the journal Psychoneuroendocrinology, will next study if this lack of cortisol upon waking also occurs in children with other types of autism.

Yale Study Suggests Children with Autism Watch for the Wrong Visual Clues - 0 views

  • Individuals with autism spectrum disorders (ASD) tend to stare at people's mouths rather than their eyes. Now, an NIH-funded study in 2-year-olds with the social deficit disorder suggests why they might find mouths so attractive: lip-sync—the exact match of lip motion and speech sound.
  • Such audiovisual synchrony preoccupied toddlers who have autism, while their unaffected peers focused on socially meaningful movements of the human body, such as gestures and facial expressions.
  • "Typically developing children pay special attention to human movement from very early in life, within days of being born. But in children with autism, even as old as two years, we saw no evidence of this," explained Ami Klin, Ph.D., of the Yale Child Study Center, who led the research. "Toddlers with autism are missing rich social information imparted by these cues, and this is likely to adversely affect the course of their development."

  • In theory, this finding could lead to educational techniques that could help very young children with autism build their social referencing skills. This could be hugely important for children with autism, since their challenges with "reading" social cues create so many problems as they enter school, interact with peers, and begin to navigate social relationships.

Why parents swear by ineffective treatments for autism. - By Sydney Spiesel - Slate Mag... - 0 views

  • Since most of the ways we diagnose autism are based on behavior, we can't rely on biological, structural, or chemical findings to determine if a treatment is working. We primarily measure success based on a patient's change, or lack thereof, in behavior.
  • The behavioral changes produced by the few effective treatments make life in social settings (including the home) possible, but we have no idea whether they have any effect on the underlying cause (or causes) of autism or whether they even make severely affected patients feel better.
  • One method intended to help, "facilitated communication," is based on the idea that a sensitive facilitator will hold the hand of a patient over a kind of Ouija board. She will then help the patient respond to questions by sensing his intention and helping guide his hand to spell out answers. Rigorous studies have shown that the spelled-out answers come from the unconscious (or, worse, the conscious) mind of the facilitator. Nonetheless, the practice is still in use, and I know parents who are utterly convinced that it is valid and useful. Frankly, something important did happen when facilitated communication was introduced to my patients: They improved, they brightened, they became more social and more interactive, and they seemed, somehow, happier, even though facilitated communication didn't actually translate their thoughts into words. I'll come back to "why" in a minute.

  • The techniques of sensory integrative treatment include rubbing or brushing skin (using graded and tactile stimulation), balance exercises, exposure to soft music, and the use of weighted clothes, among other things. Does it work? Most of the research has been of very poor quality, but, in virtually all of the recent studies, sensory integration doesn't seem to be any more beneficial than any other treatment.
  • It looks as if environmental alteration, especially if coupled with increased attention and perhaps expectation, often leads to change in human behavior. It's called the "Hawthorne effect."
  • People respond—mostly favorably—to positive attention and interaction. The question we need to ask about all the treatments available for autism is whether they actively shape and change brain development and thus treat the underlying condition, as many proponents believe, or whether the benefits (if they are present at all) are simply another example of the Hawthorne effect.
  • Perhaps my patients who became more alive and more interactive after facilitated communication was introduced changed because their families and caretakers were taking them more seriously as people who might have an inner life—people worthy of attention and interaction.

New Theory Of Autism Suggests Symptoms Or Disorder May Be Reversible - 0 views

  • the brains of people with autism are structurally normal but dysregulated, meaning symptoms of the disorder might be reversible.
  • autism is a developmental disorder caused by impaired regulation of the locus coeruleus, a bundle of neurons in the brain stem that processes sensory signals from all areas of the body.
  • The new theory stems from decades of anecdotal observations that some autistic children seem to improve when they have a fever, only to regress when the fever ebbs.
  • ...11 more annotations...
  • This study documented that autistic children experience behavior changes during fever.
  • Einstein researchers contend that scientific evidence directly points to the locus coeruleus–noradrenergic (LC-NA) system as being involved in autism. "The LC-NA system is the only brain system involved both in producing fever and controlling behavior," says co-author Dominick P. Purpura, M.D., dean emeritus and distinguished professor of neuroscience at Einstein.
  • The locus coeruleus has widespread connections to brain regions that process sensory information. It secretes most of the brain's noradrenaline, a neurotransmitter that plays a key role in arousal mechanisms, such as the "fight or flight" response. It is also involved in a variety of complex behaviors, such as attentional focusing (the ability to concentrate attention on environmental cues relevant to the task in hand, or to switch attention from one task to another). Poor attentional focusing is a defining characteristic of autism.
  • "What is unique about the locus coeruleus is that it activates almost all higher-order brain centers that are involved in complex cognitive tasks," says Dr. Mehler.
  • autism, the LC-NA system is dysregulated by the interplay of environment, genetic, and epigenetic factors
  • They believe that stress plays a central role in dysregulation of the LC-NA system, especially in the latter stages of prenatal development when the fetal brain is particularly vulnerable.
  • a higher incidence of autism among children whose mothers had been exposed to hurricanes and tropical storms during pregnancy.
  • autistic children, fever stimulates the LC-NA system, temporarily restoring its normal regulatory function. "This could not happen if autism was caused by a lesion or some structural abnormality of the brain," says Dr. Purpura.
  • future of autism treatment probably lies in drugs that selectively target certain types of noradrenergic brain receptors or, more likely, in epigenetic therapies targeting genes of the LC-NA system.
  • If the locus coeruleus is impaired in autism, it is probably because tens or hundreds, maybe even thousands, of genes are dysregulated in subtle and complex ways," says Dr. Mehler. "The only way you can reverse this process is with epigenetic therapies, which, we are beginning to learn, have the ability to coordinate very large integrated gene networks."
  • "You can't take a complex neuropsychiatric disease that has escaped our understanding for 50 years and in one fell swoop have a therapy that is going to reverse it — that's folly. On the other hand, we now have clues to the neurobiology, the genetics, and the epigenetics of autism. To move forward, we need to invest more money in basic science to look at the genome and the epigenome in a more focused way."

Autism Research Blog: Translating Autism: Expressive communication in children with sev... - 0 views

  • Given that the rate of elicited expressive communication in the present study is much lower than the suggested rate of teacher prompt, it can be assumed that teachers of students with autism do not actively promote their students’ expressive communication.
  • The results also indicate that verbal prompts and a combination of verbal prompts and modeling were the most commonly used instruction. However, simple (non-combined) prompts were most effective in eliciting a communicative response with kids with the most severe autism. But most surprisingly, physical prompts did not seem to be as effective as verbal prompts, which may also explain why verbal prompts were use significantly more by these teachers.
  • In sum, the study has implications for the type of techniques that are effective in eliciting communicative responses in children with severe autism. In this study simple verbal prompts and modeling were the most effective strategy to elicit communicative responses in these children.Chiang, H. (2009). Naturalistic observations of elicited expressive communication of children with autism: An analysis of teacher instructions Autism, 13 (2), 165-178 DOI: 10.1177/1362361308098513

Interview with Robert Koegel | Pivotal Response Treatments for Autism Author on ABC's S... - 1 views

  • The NLP became synonymous with motivation and motivation is pivotal in teaching children with autism to respond to multiple questions.
  • Children often hate having to perform drill practices involved with other autism treatments, they feel like they are being forced to do something they don't enjoy and they react to this by causing a scene to get out of treatment.
  • Why would you say PRT is more effective than other therapies
  • ...10 more annotations...
  • First and foremost, children think of it as fun and learn skills by doing what they enjoy.
  • PRT is effective in all of the child’s environments and versatile enough to use at home, in clinical settings, in an inclusive classroom, and in the community, and parents can easily start folding PRT strategies into the child's established routine right away.
  • How does PRT decrease stress for parents?
  • 1988 was the first time the word pivotal was used to describe this method. It was referred to previously as the NLP. It is considered a behavior intervention with similarities to the Lovaas method/ABA. 
  • What exactly are "pivotal responses?"
  • "areas that are central to wide areas of functioning such that improvements occur across a large number of behaviors." 
    • Tero Toivanen
       
      Pivotal responses määrittely!!!
  • Once they understand the connection between using their own words and getting something they want, they will start to use words spontaneously to communicate their needs. Mastering this one pivotal behavior, motivating the child to understand the connection between their own efforts to communicate with the outcomes of their efforts, will have an enormous ripple effect on other skills.
    • Tero Toivanen
       
      In practice.
  • It works because there is a motivator that makes the child want to work to accomplish the task at hand, the reward for accomplishing the task has a direct connection to it.
  • PRT was named by the National Research Council of the National Academy of Sciences in 2001 as one of the top 10 state-of-the-art treatments for autism in the United States.
  • A child who is highly motivated to communicate and is having fun doing it will learn much more rapidly than a child who is not motivated and not enjoying what they are learning.
