Anesthesia and LD


Cumulative percentage of learning disabilities diagnosis by the age at exposure shown separately for those that have zero, one, or multiple anesthetic exposures before age 4 yr. (Fig 1 from Wilder et al., see sources).

Writing in the academic journal Anesthesiology under the title “Early Exposure to Anesthesia and Learning Disabilities in a Population-based Birth Cohort,” Robert T. Wilder, M.D., and colleagues reported that young children’s exposure to anesthesia was associated with a significant risk for development of Learning Disabilities in children having anesthesia two or more times during early childhood. Although the findings are consistent with analog studies showing that anesthetics affect baby animals’ brain development, they do not necessarily indicate that the drugs caused the children’s LD; one or more other factors could have caused both the need for the surgeries and the LD.

The investigators studied the association between anesthetic exposure before age 4 yr and the development of learning disabilities (LD). A single exposure to anesthesia (n = 449) was not associated with an increased risk of LD (hazard ratio = 1.0, 95% confidence interval [CI], 0.79-1.27). However, children receiving two anesthetics (n = 100) or three or more anesthetics (n = 44) were at increased risk for LD (hazard ratio = 1.59, 95% CI, 1.06-2.37, and hazard ratio = 2.60, 95% CI, 1.60-4.24, respectively). The team noted they cannot determine whether anesthesia itself may contribute to LD, or whether the need for anesthesia is a marker for other unidentified factors that contribute to LD.

In the following video, two of the researchers discuss the project and it’s implications.

Research input opportunity

Here’s a copy of a post I put on EBD Blog that has content that’s also relevant here.

The US Interagency Committee on Disability Research (ICDR) is seeking citizens’ recommendations about a research agenda. Although this initiative aims at addressing issues for adults in the community, which differs from the focus of EBD Blog (educational issues related to children and youth and their families), I want to mention it here so that readers who may have interests in health, employment, and similar topics will get the news.

This year for the first time, the federally mandated Interagency Committee on Disability Research (ICDR) is utilizing an innovative Web-based approach to collect online disability research comments to assist in developing a federal disability and rehabilitation 2010 research agenda. This technology-driven approach gives the public a three-week timeframe from March 27th through April 17th to submit their recommendations. Additionally, registered participants will be invited to review all comments submitted and vote on their top 10 concerns in each topic area during the one-week period from April 22nd through April 29th. Public comments from stakeholders are the focal point of the disability research recommendations in the ICDR Annual Report to the President and Congress.

Stop slurring

I’m talking about speech, but not about speaking indistinctly and running one’s words together. I’m talking about speech that insults.

Over on One Special Place, Renee Beauregard has a post deriding the use of “retard” and its variants (‘tard, ‘tarded, etc.) in common speech.

Do you have any idea how many times people with developmental disabilities are called the “R” word – in a way that is meant to be derogatory? And now, this word has become an adjective used as much as any other negative word to describe a person.

The history of disabilities is replete with terms that were once used clinically as well as insultingly: imbecile, idiot, moron, and others. Now that groups such as the American Association on Intellectual and Developmental Disabilities (AAIDD; formerly American Association for Mental Retardation or AAMR) have changed their names, maybe the term “retard” as a slur can take its place on the slag heap of misbegotten insults.

Ms. Beauregard notes some examples of people taking offense at this use of the term. Link to her post. There are other resources available, too. Check Alex Santoso’s post from Neatorama for notes about the usage of some of these terms. Meanwhile, have a little consideration, please.

Kirk used “Learning Disability” before 1963

I was fiddling around with a new feature of Google and thought I’d test its use on a task. Having just read the only entry in the proposed canon for LD (please add to it, folks), I thought I’d search for instances of the perpetuation of the myth that S. A. Kirk coined the term Learning Disability in 1963 in a speech to the group that would become the Association for Children with Learning Disabilities (and, ultimately, the the Learning Disabilities Association of America, and of many other countries, too).

“But, everybody says that’s when he coined it, don’t they?” Not really. Some folks know that Professor Kirk and Barbara Bateman had already used the term “Learning Disabilities” in a paper published a half year earlier (and, given the delay between submission and publication of an article, they’d likely used the term at least a year before the famous meeting).

This analysis does not take anything away from the importance of the meeting in Chicago; that was a signal event, an illustration of the political clout of parents who rally around a common theme in the service of their children. That meeting was the beginning of what one might call the Learning Disabilities movement in the US and now the world. In fact, the LDA site doesn’t make the mistake about the birth of the term; it simply recounts the momentuous events that occured there and then.

Professor Bateman explained it correctly (and she should know) in her 2005 paper “The Play’s the Thing”: “The definition of LD, now controversial, was not an issue when the term learning disabilities was first introduced by Kirk in 1962.”

Anyway, I started a list of places where writers have perpetuated the myth that the term “Learning Disabilities” was introduced in 1963 at the Chicago meeting. Here are a few.

  • “Dr. Kirk’s most influential pronouncement was a speech he delivered to an education conference in 1963, when he coined and defined the term ‘learning disabilities.’”
    New York Times obituary for Professor Kirk.
  • “The phrase ‘learning disability’ was coined here in Chicago in 1963 by Kirk”
    Psychpage
  • “The term learning disabilities was first coined in 1963 by Samuel Kirk”
    2005 Newsletter of the Oregon chapter of Learning Disabilities Assocation of America.
  • “The term learning disabilities was first coined in 1963 in Chicago, Illinois, by Samuel Kirk,”
    Doris Johnson’s abstract for a plenary session at the University of Pennsylvania.
  • “The term learning disability was first coined in a speech that Samuel Kirk delivered in 1963 at the Chicago Conference on Children with Perceptual Handicaps.”
    S. W. Lee in The Encyclopedia of School Psychology (p. 290).

But, I really ought to give credit to those who got it right, who didn’t repeat the misinformation. Ahhh, but that’s another entry.

Sprout Film Festival comes to C’ville

Anthony DiSilvo reminded me that the Sprout Film Festival will be in my neighborhood. Although it’s not expressly about Learning Disabilities, it’s relevant to LD Blog for other reasons (e.g., achievements of individuals with disabilities).

SPROUT FILM FESTIVAL “Making the Invisible Visible”

Two Shows! 10:30 am – 12:00 pm (Free Admission)
7:00 pm – 9:00 pm ($10 suggested donation) at the Martin Luther King, Jr. Performing Arts Center in Charlottesville, Virginia.

Tickets are general admission and available at the door.

People with developmental disabilities as subjects and performers remain marginalized in the media. The Sprout Film Festival aims to raise their profile by showcasing works of all genres featuring this population.

By presenting films of artistry and intellect, the festival hopes to reinforce accurate portrayals of people with developmental disabilities and expose the general public to important issues facing this population. The goal is an enjoyable and enlightening experience that will help breakdown stereotypes, promoting a greater acceptance of differences and awareness of similarities.

The local event is sponsored by the Piedmont Regional Education Program. Here’s a link to the flyer for the event and here’s a link directly to the PREP Web site. I’ve run notices about SFF in New York City over on Teach Effectively or SpedPro in the past. One about this year’s festival will appear on SpedPro pretty soon. Here’s a link to the NYC event.
