Thimerosal Cause Neurological Damage Like Autism in Rats

Monday, December 7th, 2009



Written By Lourdes Salvador of www.americanchronicle.com

Autism is a neurodevelopmental disability characterized by social withdrawal, communication deficits, and repetitive behaviors. Both genetic and environmental factors have been implicated as causes of autism, moreover a high body burden of mercury and other toxic metals from vaccinations and environmental exposures has been increasingly given more attention.
Thimerosal is mercury containing vaccine preservative added to many childhood vaccines. It is widely suspected as a cause of an increasing widespread epidemic of childhood neurodevelopmental disorders such as autism.
Now, a new study shows that administration of thimerosal leads to long lasting neurological impairment in rats, specifically by altering the neural process of handling noxious stimuli.
Analysis also shows that significant amounts of mercury from thimerosal accumulates in the rat brain and remains long term. The mercury is not readily cleared, as was previously believed. Though mercury readily leaves the blood stream, it does not leave the body. It is now recognized to accumulate in brain tissue.
Additionally, this research is supported by various prior studies which show that children with autism suffer from a weak ability to excrete mercury and that the weaker the ability, the more severe the symptoms of autism.
Now, two new research studies investigating the effects of chelation therapy on the health and behavior of children with autism spectrum disorders have discovered that children receiving chelation to reduce mercury levels had significant improvements.
It appears that mercury may produce they symptom set recognized in the autism spectrum disorders as a form of autism.

Thorkil Sonne: Recruit Autistics

By Drake Bennett

Most occupations require people skills. But for some, a preternatural capacity for concentration and near-total recall matter more. Those jobs, entrepreneur Thorkil Sonne says, could use a little autism.

Sonne reached this conclusion six years ago, after his youngest son was diagnosed with the mysterious developmental disorder. “At first I was in agony and despair,” he recalls. “Then came the thought of what happens when he grows up.”

In Sonne’s native Denmark, as elsewhere, autistics are typically considered unemployable. But Sonne worked in IT, a field more suited to people with autism and related conditions like Asperger’s syndrome. “As a general view, they have excellent memory and strong attention to detail. They are persistent and good at following structures and routines,” he says. In other words, they’re born software engineers.

In 2004, Sonne quit his job at a telecom firm and founded Specialisterne (Danish for “Specialists”), an IT consultancy that hires mostly people with autism-spectrum disorders. Its nearly 60 consultants ferret out software errors for companies like Microsoft and Cisco Systems. Recently, the firm has expanded into other detail-centered work-like keeping track of Denmark’s fiber-optic network, so crews laying new lines don’t accidentally cut old ones.  Read more at WIRED.com

Easter Seals and Autism Services

I found this on the Easter Seals site and suggest  visiting their site for more in depth information on Autism and Services needed for children on the spectrum.

Understanding Speech and Hearing Therapy

Speech and hearing therapy (also known as speech-language pathology and audiology) are important health-related specialties concerned with normal development of human communication and treatment of its disorders. Speech therapy focuses on voice and speech-language skills, while hearing therapy deals with hearing and hearing impairment.

Speech or language disorders may be present at birth or acquired later in life by disease, illness, head injury, substance abuse or allergy.

Hearing loss may be acquired before or during birth if a pregnant woman takes certain drugs or contracts a viral disease such as rubella (German Measles). Children sometimes acquire hearing loss from infection and inflammation of the middle ear or from communicable diseases. Adult hearing may be affected by prolonged exposure to loud noise and the process of aging.

Who Needs Speech-Language Pathology and Audiological Services?

Speech-Language Pathology is used to help:

* Individuals with voice disorders to develop proper control of their vocal and respiratory systems
* Individuals who stutter to learn to cope with the disorder and increase fluency
* Individuals with aphasia (a condition in which an individual has difficulty expressing thoughts and understanding others) as a result    of a stroke or head injury. Speech-language pathology helps individuals relearn language and speech skills.
* Children and young adults with language disorders

Audiological services are used to:

* Determine existence and type of hearing impairments
* Provide rehabilitative services
* Assess amplification devices, such as hearing aids
* Teach individuals ways in which they can make the best use of their remaining hearing

Speech and hearing therapists, recognized as speech-language pathologists and audiologists, who provide treatment are professionally trained specialists holding master’s degrees or the equivalent from programs accredited by an Educational Standards Board of the American Speech-Language-Hearing Association (ASHA).

Some speech-language pathologists and audiologists hold doctoral degrees and work as teachers, advisors, researchers and consultants. Some specialize in certain areas, such as aphasia or hearing disorders in children, or participate in prevention and early identification programs.

Speech-language pathologists who use the initials “CCC-SLP” after their name have passed a national examination administered by the Clinical Certification Board of ASHA. Audiologists who pass a different national test, administered by the board, receive a Certificate of Clinical Competence in Audiology and qualify to use the initials “CCC-A” after their name. A person who meets requirements in both professional areas may be awarded both certificates.

Individualized Treatment Plans

A speech-language pathologist evaluates a person’s speech-language skills, determines the probable cause and extent of any existing disorder and develops appropriate treatment to correct or lessen the communication problem. Clinical methods used depend on the nature and severity of the problem, the age of the client and the client’s awareness of the problem.

An audiologist, after evaluating a person’s hearing and determining the type of hearing loss, establishes a treatment plan. This may involve therapy, prescription of special equipment such as hearing aids and electronic communication devices and referral for possible surgery or medication.

Autism-Spectrum Quotient – AQ

Thursday, June 18th, 2009

Psychologist Simon Baron-Cohen and his colleagues at Cambridge’s Autism Research Centre have created the Autism-Spectrum Quotient, or AQ, as a measure of the extent of autistic traits in adults. In the first major trial using the test, the average score in the control group was 16.4. Eighty percent of those diagnosed with autism or a related disorder scored 32 or higher. The test is not a means for making a diagnosis, however, and many who score above 32 and even meet the diagnostic criteria for mild autism or Asperger’s report no difficulty functioning in their everyday lives. You can take the test here.

Video Modeling … seems like a great idea!

Saturday, July 5th, 2008

Came across this video series, http://www.modelmekids.com/autism-videos.html

Anyone ever use it? What were your results? Seems like a great idea and one I have often thought about given my sons love of the video tape, or dvd.

Thanks for sharing… is there anybody out there??

The Time for School video presents social skills in the context of school. It features elementary school-aged children demonstrating appropriate social skills in the classroom, library, on the playground, and in the hallway. Each scene lasts between 30 seconds and 3 minutes, depending on the chapter. At the end of each chapter is a storyboard summarizing the rules taught.

The video is hosted by a young boy, who narrates each scene.

With narration: In the first half of the video, the visual is combined with narration and graphics that help explain the particular rule.

Without narration: In the second half of the video, the same video is repeated without narration and graphics. This allows a parent, Autism teacher, or therapist to customize the lesson the individual child and/or to test what was learned in the first viewing of the video.

Each social skill is demonstrated in more than one situation and across environments. This is useful to children with Autism and Asperger’s Syndrome because it helps with generalization of the skill taught.

Graphics and music are used to make the video appealing to children with Autism, Asperger’s Syndrome, and Nonverbal Learning Disorders. A high production value helps keep the child’s interest so that he or she will want to watch many times.

Autistic Kids: The Sibling Challenge

Monday, January 7th, 2008

By Amy Lennard Goehner,
Time Magazine, Dec. 24, 2007

A few months ago, I took my sons to buy shoes. Nate is 14 and autistic. Joey is 8 and “typical.” And I’m the parent — most of the time. Before we got to the store, Joey said to me, “If Nate has a tantrum, I can handle him. You just focus on buying shoes. I’m better at handling tantrums than you. Sometimes you just yell and it makes things worse. No offense.”
None taken. He’s absolutely right.
The “typically developing” siblings of autistic children are, in fact, the furthest thing from typical. Often, they are wiser and more mature than their age would suggest. And they have to be, given the myriad challenges they face: parental responsibility; a feeling of isolation from the rest of their family; confusion, fear, anger and embarrassment about their autistic sibling. And on top of all of it, guilt for having these feelings.
As their parents, there’s a lot we can do to help. For starters, we can educate them early on, by explaining their sibling’s disorder — a conversation that should be ongoing. Dr. Raun Melmed, co-founder and medical director of the Southwest Autism Research and Resource Center in Phoenix, suggests including non-autistic children in visits to the doctor or other autism professionals. Early intervention doesn’t have to be “thought of as being geared only to the involved child,” Melmed says. In his office, Melmed reassures siblings that “other brothers and sisters have negative and confusing thoughts about their [autistic] siblings. That is common.” He also instructs parents to reaffirm that message at home. “Parents need only acknowledge to their healthy children that they know what they are going through and that negative feelings are normal,” he says.
A great way for kids to feel “normal” is to meet other siblings of autistic children, which they can do at sibling workshops. At the Kennedy Krieger Institute for children with developmental disabilities in Baltimore, social worker Mary Snyder-Vogel runs a program called Sibshops. “The workshops give these kids the opportunity to realize they’re not alone,” Snyder-Vogel says. “[We play] a lot of games that help them interact and problem-solve with peers. Kids don’t even realize they’re getting support.”
At a recent Sibfun workshop at the Jewish Community Center on Manhattan’s Upper West Side, therapists used puppet shows to illustrate issues that are common among siblings of special-needs kids. When asked what they thought the puppets were feeling, the children in the audience needed no prompting, immediately shouting out words like sad, disappointed and jealous.
Siblings will commonly have negative feelings — some might never connect or want to connect with their autistic siblings — but the good news is that typical siblings often turn out to be more compassionate and caring than average. “These siblings have seen what it’s like to have a hard time in life,” says Sandra Harris, executive director of Rutgers University’s Douglass Developmental Disabilities Center, a program for people with autism spectrum disorders and their families, and author of Siblings of Children with Autism: A Guide for Families (Woodbine House).
There are many other, more specific challenges that affect siblings of special-needs kids — and many of them apply to sibling relationships of every kind. Here are some of the issues that most frequently confront typical siblings — and their families — with advice from professionals.

Challenge #1: “Why won’t he play with me?”

For younger siblings of autistic children, one of their first doses of reality usually comes when their older brother or sister won’t play. “The child on the [autism] spectrum may seem indifferent or have a meltdown when the sibling tries to interact,” says Rutgers’ Harris.

Seven-year-old Adam, whose autistic brother Jacob is 11, says, “I can’t really play games with Jacob like I can with my cousin Eric [also 11]. Jacob likes to play games on the computer — but by himself, not with me. He gets too angry if he loses and then doesn’t want to play.” Adam’s father, Paul, says soberly, “I’m sure Eric represents the brother Adam might have had.”

Solution: Find common ground

Parents can start by telling the typical sibling that his brother or sister “is doing the best he can, and here are some things you can do with him,” says Judy Levy, director of social work at the Kennedy Krieger Institute. “Maybe in the future he’ll be able to learn to play with you in other ways, but right now this is what he can do.”

Harris encourages parents to “find ways in which the siblings can relate [or] share an interest.” That can be something very simple, as Elliot learned at an early age. “It turns out my brothers [Benjamin and Aaron] are really ticklish,” says Elliot. “Tickling was a good way to bond with them, and for them to show affection back by laughing and wanting it again.” (And again and again — and again.)

Challenge #2: “It’s not fair!”

Every parent has heard his or her child say, “It’s not fair!” But for families with autistic and typical siblings, “not fair” is the reality, when it comes to one child being treated differently from the other. Martin Bounds has one autistic child, Charlie, 13, and one typical child, Alex, 15, about whom Bounds says, “He’d get very upset when he would bump his knee or complain of feeling sick. He thought we weren’t sufficiently concerned about him, in the spirit of ‘I could be over here dying, and all you care about is Charlie.’”

That may be overstatement, but such sentiments often stem from legitimate gripes. Bounds recalls when he and his wife attended an important fund-raiser for Charlie three years ago, on the same day Alex rode in an annual bike race. “Alex won the race for his age group and was really upset when we were not there to greet him at the finish line,” says Bounds. “As much as you try to balance schedules, as parents of an autistic child, you have to basically accept that you are going to have moments when you feel you have cheated your other children, and those moments are awful.”

Solution: Create special time

Harris urges parents to set aside alone-time with their typical kids every week. “Private time can even [include] riding in the car to pick up the laundry,” she says, “but since [the child is] with Daddy, [he or she is] the focus of his attention.”

Some kids, like Elliot, develop new hobbies as a way to spend time with a parent. “Gardening was something I could do with just my mom — it was never easy to get my mom to myself,” he says. Elliot began gardening five years ago; he’s now a junior judge at flower shows and grows about 330 varieties at home, including the 170 seedlings he has hybridized.

For single parents, however, eking out one-on-one time can be a daunting task. As a widowed mom, I know firsthand — we do the best we can with the time we have. Single dad Ron Barth says his autistic 9-year-old, Daniel, “dominates everything, so I have to make special moments with Nicole [age 15], like taking her shopping — without Daniel.” But, says Barth, “There aren’t enough of those moments.”

Challenge #3: “I’m scared!”

Some autistic children are aggressive, which can be scary and dangerous, especially for younger kids. And parents can’t possibly keep an eye on their kids every second — which is about the amount of time it took for one child I interviewed to get squirted in the eyes with Windex by her younger autistic brother. (She survived just fine.) Even my son Nate, who isn’t aggressive but is twice the size of Joey, often hugs Joey — tight. Very tight. Around the neck. When Joey yells “MOM!” I’ve learned to tell the difference between Mom, can you help me find my Gameboy? and MOM, he’s choking me!

Solution: Find a safe haven

“I tell parents to have a ‘safe place,’ usually the child’s room, where the typical child can go while an adult handles the behavior problem,” says Harris. “Then, as soon as they can, the parents should comfort the typical child and help him or her understand what happened.”

Harris also suggests that parents develop an “intervention plan” to teach the child with autism alternate behaviors — such as asking to be left alone, or using words, cards or a special gesture — when he or she feels upset. “Kids with autism can learn to go their room, sit in a beanbag chair, or do something else that helps them calm themselves,” says Harris.

Challenge #4: “He’s so embarrassing!”

It’s common for siblings to feel embarrassed by their autistic brother or sister’s behavior in public, or to be reluctant to bring their friends home. Kelly Reynolds, 21, says it can be difficult introducing her autistic brother, Will, to her friends: “It’s hard to have a young child in an older kid’s body. [Will] may go up to one of my girlfriends and sit on her on the couch — which probably would have been cute when he was five years old but he’s 17 now,” Reynolds says. “That can be hard because you can tell when someone feels awkward or scared or thrown off.”

Solution: Encourage honesty — and laugh

“Interestingly, a lot of these [typical sibs] are more outspoken,” says Levy of the Kennedy Krieger Institute. “They’ll go up to people and say, ‘Yes, that’s my brother. He has special needs. Do you have any questions?’”

My son Joey is one of those kids. When he was 6, we were at a bus stop when Nate started jumping up and down and making weird noises — just being Nate. When Joey’s friend started making fun of Nate, Joey got right in her face and said, “Do NOT make fun of my brother again! Everybody learns differently.” They were my words coming from Joey’s mouth.

Several parents I interviewed said a sense of humor is key. “Your typical child can see the humor in the actions of his autistic siblings,” says Bounds, father to Charlie and Alex. “It’s okay to talk about his or her ‘weird brother’ in a way that signals that you both know this isn’t normal.”

When Nate does something bizarre in public, which is just about whenever he’s in public, Joey and I often give each other an Oh, my God! look and roll our eyes, which sort of says, “We’re in this together.”

Challenge #5: “I feel like the parent.”

Angela Bryan-Brown, 15, says she often feels like a parent to her 14-year-old brother Alasdair. “You don’t have a choice,” says Angie. “You’ve got to help out, and your parents can only do so much. They’re so stressed out.” Angie’s mom Florie Seery refers to Angie as “the third parent in the house” and “an old soul,” a phrase I’ve heard often from other parents.

Elliot says of his siblings’ disorder: “Even though I’m four years younger, it places me in the position of being the older brother. ”

Solution: Let sibs be children too

“It’s a challenge for children to feel that sense of responsibility for their sibling,” says Harris. “A wise parent works hard to temper that and to make the responsibilities fitting to the age of the siblings. An older sister can keep her brother entertained for half an hour because an older sister would typically do that to help out — but she’s not a parent.”

For young siblings, Harris suggests counseling them: “‘It’s wonderful to care about your brother, but you’re my little boy too. Because your brother has trouble learning sometimes, he might need help from you, but you’re not his mommy or daddy. We will take care of him when he needs help.’ That kind of message reaffirms one’s love and lifts that burden.”

Challenge #6: The holidays

“Attending loud, busy social gatherings with new sights, sounds, smells, intrusive relatives and strange places overwhelms the best of us, let alone those with sensitive sensory systems,” says Dr. Raun Melmed of the Southwest Autism Research and Resource Center. “Of course, when the child gets overwhelmed and melts down, so do the siblings and parents.”

“In short, holidays suck, especially the ones you spend outside your own home,” says dad, Bounds. “They’re full of the most dreaded thing in an autistic life — unstructured time. People get together with relatives and friends and talk — which is sort of hard to do when your child has your sister-in-law’s cat by the throat and is about to put him in the food processor.”

Solution: Ask family members to help

Harris suggests that parents “create a rotating team of adults. Each person spends a half-hour with the child, so that parents and siblings aren’t trapped, and the child doesn’t have to be exposed to the chaos of the party. Cousins and aunts can take a turn.”

Siblings, however, should be spared. “The typically developing kid wants the holiday to come. She’s off from school, she’s getting her present and she can’t really enjoy that” if she’s expected to take care of her autistic brother or sister, says social worker Snyder-Vogel.

Challenge #7: In adulthood, the sibs will become “parents”

Someday, inevitably, the sibling of an autistic child will most likely take on the role of guardian and advocate. “You’re basically at some point going to be their parent,” says Kelly Reynolds, 21. “Anyone I want to marry has to take that into account. In some ways you kind of feel like you already have a kid. … For me, it’s kind of a deal-breaker when someone can’t really get along with my brother. He’s such a big part of my life.”

Solution: Discuss future plans with adult children

Parents should talk about financial plans and any care arrangements that have been made, once typical siblings are old enough, says Harris in a recent article for the Autism Society of America. But this isn’t a discussion to initiate with younger children — unless they bring the topic up on their own.

Many of the children I interviewed showed deep concern for their autistic brothers and sisters. And nearly all of the professionals and doctors I talked with said that a disproportionate number of their students and residents were siblings of people with autism. “I’m very interested in trying to help find a cure,” says 15-year-old Elliot, who closely follows news about the disorder. “I’d just like to get a neat little pill someday for my siblings that they can pop in with their apple juice and hopefully be normal.”

Signing Time Doesn’t Fit the Mold

Monday, September 10th, 2007

By Chris Higbee, VP Marketing, Two Little Hands Productions

((I can tell you first hand, we owe a ton of gratitude to Signing Time, it has proven to be one of the top 2 most effective things to stimulate speech and communication))

A recent study out of the University of Washington written by Dmitri A. Christakis and Frederick J. Zimmerman suggests children’s educational videos may do more harm than good. The press release announcing the publication of the study in the Journal of Pediatrics specifically calls out Baby Einstein and Brainy Baby as ineffective. However, the press release and the study irresponsibly ignore the fact that the children’s educational programming market is comprised of vastly different products, which target different audiences and espouse different goals.

As a parent, I definitely understand the medical and scholarly communities’ concerns with overexposing our children to the potential pitfalls of television. Commercials. Sedentary viewing. The alienation of children from the family. The development of inappropriate habits. And I don’t necessarily disagree with Zimmerman and Christakis when they infer that unsupervised and non-interactive viewing can be counterproductive and keep children from reaching their full learning potential.

However, as a developer of children’s educational programming, I take issue with the idea that it’s all the same, causing readers to create incorrect and unfair associations between programs as a result. Here at Two Little Hands Productions, we receive dozens of letters and e-mails each day from our customers expressing their gratitude and sharing their success stories of how their children have grown because of Signing Time. A majority of these letters describe how children of all abilities have overcome language development problems as a result of Signing Time. Parents are often also pleasantly surprised to discover the positive effects of Signing Time on bonding and their personal relationship with their children due to its interactive nature. This anecdotal evidence along with scholarly research on sign language as a communication development device and on audio-visual learning strongly support our belief that certain types of educational content, are best suited to a video format when supervised and watched in moderation; sign language is one of those.

Sign language is a three-dimensional language. While it can be learned from books, the best way to learn sign language is to see it in motion. High quality live instruction is the best method for learning sign language, but video is also an ideal format. In fact, video or television provide something that live instruction cannot; a cost-effective and ubiquitous means of distributing it to children and adults who are interested in learning it but cannot afford or find live instruction. Additionally, learning aids such as music, animation, mnemonics, and interactive activities can be incorporated in to a video or television program much easier and more cost effectively than live instruction. And, as any early childhood professional will tell you, these types of aids have the greatest possible effect on the widest possible audience of children with varied learning styles and abilities. Additionally, for those families and educators who prefer printed media, Signing Time provides board books and flashcards that can be used on their own or supplement the instruction provided on the videos.

Another key teaching aid is interactivity. Children not only internalize concepts better, but they develop stronger communication and interpersonal bonds as they share those concepts with family and friends. Sign language provides a perfect medium for this and Signing Time is designed with this type of interactivity in mind. A child can learn sign language on his own, but what’s the point if he has no one to sign with? As with all forms of useful communication, sign language is a sort of positive epidemic. If it’s useful, it gets spread. Even if a child watches Signing Time alone, she will spread sign language directly by teaching it to friends and family, or inadvertently as curious friends and family see her using it.

Signing Time is designed for co-viewing. Signing Time is meant to be watched together by children and their parents. Even when watched separately, parents and children will use what they’ve learned from Signing Time away from the television to communicate and bond.

Signing Time was designed to teach children AND their families. This includes mom, dad, siblings, grandparents, and caregivers. In fact, Two Little Hands Co-Founder, Rachel Coleman has said regarding the founding of the company “I was tired of my dad, after three years, asking what the sign for ‘Grandpa’ was. When we originally set out to create Signing Time our goal was simple; teach Dad (and others who interacted with my daughter Leah, who is deaf) to sign.” Through the use of original music, clever animation and teaching a fun and engaging language, Signing Time has steered clear of the pitfalls of many other children’s educational programs that keep parents from watching with their kids; it’s not boring or annoying and most importantly creates an environment where children and parents learn together. The other day, I received a call from a convent in Canada where one of the nuns is deaf and the others wanted to learn sign language so they could communicate with her. One of them had seen Signing Time at a childcare center in which she was volunteering and ended up liking it so much, she told the convent and they purchased our entire DVD library over dozens of adult-oriented sign language programs, because it was fun to watch.

Signing Time is being used by state and federal education programs. Many preschools and elementary schools around the country are incorporating sign language into their regular curriculum because it is such an effective tool with young children. A large number have incorporated Signing Time in to this curriculum. Clark County School District in Las Vegas, Nevada has made it part of their ready to learn program for pre through K, while the Hawaii state legislature has put out an official declaration that Signing Time should be considered when incorporating sign language in to any state-approved special education program (http://www.capitol.hawaii.gov/sessioncurrent/Bills/HCR223_.htm). Additionally, we receive emails and letters from families who have been referred to Signing Time by their pediatricians and speech and language pathologists. An example follows:

“I am a Speech-Language Pathologist and have been recommending these videos to all of my clients. Every single one has loved it! I do too! These are the best videos—entertaining, educational, and fun! I stop people on the street to tell them about Signing Time!”

-Laurie Grief
Mesa, AZ

The benefits of Sign Language as an educational aid are well documented by respected scholars. Drs. Joseph Garcia, Linda Acredolo, Susan Goodwyn, Marylin Daniels and many other highly respected researchers have documented the benefits of signing with hearing children. In fact, Dr. William Sears, noted author of “The Baby Book” has said of Signing Time, “We heartily recommend Signing Time books and videos – not only because they are particularly effective and fun, but because they encourage family bonding through communication at an early age.” While this is not the place to cite all of the scholarly work that shows what a powerful influence for good a television show or video series such as Signing Time can be—suffice it to say that overwhelmingly supportive research is out there and can be easily found in any university or public library. However, as with any thing we assign value to, Signing Time’s only real value lies in whether it has been effective in meeting the needs of its viewers. As mentioned before, we are overwhelmed with customer letters affirming that we have, but the best measure of our effectiveness, and this may seem very commercial for the scholars out there, but it is whether customers continue to demand it enough to keep Two Little Hands in business.

Impaired Facial Recognition Linked to Social Problems in Autism

BRISTOL, England, Aug. 30 — Autistic children have an impaired ability to place unfamiliar faces in memory, possibly explaining some of the social difficulties associated with the disorder, investigators here concluded.

Keep In Mind

* This study shows that children with autism appear to have a reduced ability to adapt mentally to faces that differ substantially from familiar faces.

* This study suggests that reduced facial recognition abilities might be related to social problems associated with autism.

* Note that the findings are based on a small number of patients.

Specifically, children with autism have difficulty with face identity aftereffect, the ability to fix in memory faces that are polar opposites of familiar faces, Elizabeth Pellicano, Ph.D., of the University of Bristol, and colleagues, reported online and in the September issue of Current Biology.

The human brain seemingly has the ability to encode new faces in a “face space,” Dr. Pellicano explained. Average or typical faces are in the center of the space. More distinctive faces lie toward the periphery, making them easier to distinguish from faces that are closer to average.

In people with normal face recognition abilities, she continued, the brain automatically places a new face in the face space on the basis of deviations from the average.

“The really neat bit is that the precise characteristics of what constitutes an average face are continuously updated based on our experiences in looking at other people,” said Dr. Pellicano.

In the current study, the face identity aftereffect capabilities of 14 high-functioning boys with autism spectrum disorder were compared with those of 15 age- and ability-matched nonautistic boys (mean age about 11 years in both groups).

Scores on standardized tests showed the two groups had similar verbal and nonverbal abilities, but they differed significantly on the Social Communication Questionnaire (P<0.001).

The study participants were introduced to the faces of “Dan” and “Jim,” who were described as “team captains.” The boys then viewed computer-generated faces that resembled Dan or Jim to varying degrees. The two groups of boys demonstrated similar ability to place the new faces on Dan’s or Jim’s team.

The boys then viewed computer-generated faces that had features that were opposite those of Dan or Jim. After viewing these distinctly different faces, the normal boys substantially improved their ability to place faces that resembled Dan or Jim on the correct team. In contrast, the autistic boys showed little improvement in their aftereffect abilities (P<0.05 versus the normal group).

In the group of autistic boys, aftereffect scores had a significant correlation with Social Communication Questionnaire scores (r= -0.60, P<0.05). For the typically developing boys no significant correlation existed between aftereffect and the communication scores.

Dr. Pellicano and colleagues examined a subgroup of nine autistic boys with high social communication scores associated with more symptoms related to socialization, communication, and restrictive/repetitive interests. The boys’ aftereffect was about one-third that of the typically developing boys (P<0.01).

Because the normal and autistic groups demonstrated similar precision for recognizing Dan-like and Jim-like faces, the investigators ruled out poor identification performance or task motivation as the cause of reduced aftereffect in the boys with autism. Moreover, the boys inspected the faces with a similar degree of intensity.

“Reduced attention to the adapting faces could potentially contribute to the weaker aftereffect in autism, and we see the relationship between adaptation and attention as a promising direction for future research,” the authors stated.

Although face-reading difficulties might contribute to the social problems characteristic of autism, an early lack of interest in social phenomena could contribute to development of atypical face-coding mechanisms, they added.

The authors had no disclosures. The study was supported by the Australian Research Council and the Experimental Psychology Society of England.

DALLAS, Sept. 6 — Clues into how autism spectrum disorders work may emerge from mice with a mutation that makes them socially awkward but enhances cognitive abilities.

Points to Consider

* The research described here was conducted only in mice, and that it is not known whether the same findings apply to people.

* The genetic mutation the authors described is seen in only a small percentage of people with autism spectrum disorders.

Transgenic mice with a mutation in the gene encoding for neuroligin-3, a synaptic cellular adhesion molecule, showed both social impairment and enhanced spatial learning abilities, a mix typical of some patients with autism, Asperger’s syndrome, or related conditions, reported Thomas C. Südhof, M.D., of the University of Texas Southwestern here, and colleagues.

The behavioral changes the investigators observed in the mice were accompanied by increases of inhibitory synaptic transmission but not excitatory transmission, the authors reported online in Science Express, the rapid online version of Science.

“Our data strongly support the notion that a change in the inhibitory-excitatory balance contributes to the pathogenesis of autism spectrum disorders,” they wrote.

If it can be shown that the mouse model accurately mimics the pathology of autism, it would suggest the possibility of treating some forms of autism spectrum disorders with therapies that can attenuate inhibitory synaptic transmission, the investigators said.

To see whether autism may be caused by an imbalance in synaptic circuits, the authors bred mice with an R451C-substitution in the gene encoding for neuroligin-3. A related mutation in humans is associated with familial idiopathic autism.

The investigators also bred a line of neuroligin-3 knockout mice for comparison purposes. They found that both murine strains appeared to be physically normal and had normal life spans.

The genetic substitution resulted in about a 90% reduction in neurologin-3 in the forebrain, and the deletion of the gene results in complete absence of the cellular adhesion molecule. However, mice with the R451C-substitution had an increase in the strength of inhibitory synaptic impulses, whereas the knockout mice did not. There were no significant changes in excitatory synaptic transmission.

The investigators then looked at the behaviors of the animals with the gene substitution to see whether the changes in synaptic transmission translated into changes in social behavior.

They found that the R451C-substitution mice were no different from wild-type controls in the time they spent examining a new inanimate object in their cages. But when a new caged adult mouse was introduced, they showed a small but significant decrease in interaction times compared with wild-type mice.

Although the neuroligin-3 deficient mice had social deficits, they appeared to have enhanced spatial memory, taking fewer days to learn the location of the submerged platform in a swim test, and finding the platform location nearly twice as often as controls.

“This combination of electrophysiological and behavioral effects is quite remarkable,” Dr. Südhof said. “It was also significant that these mice did not exhibit any other impairment of nervous system function — there was no abnormal locomotor activity or motor coordination, for example. This was a selective change, with social impairment on the one hand, yet cognitive enhancement on the other.”
