More mitochondrial dysfunction than expected?

November 30, 2010 45 comments

This Science post is by Staff blogger, Leanne Chukoskie, Ph.D.

Like most parents, the Jensens had little information about the factors that might help explain their son’s autism other than it was compounded by severe and frequent seizures.  When their son was tested, however, they learned that Levi’s cells harbored a mutation that affected the way his cells produced energy.  The Jensens now had valuable information to help treat their son.  For individuals with his particular type of mitochondrial dysfunction, certain seizure medications can cause serious side effects.

In a way, Levi Jensen was lucky. He lived near a large research center that specializes in mitochondrial disorders which is funded by Autism Speaks to investigate the role mitochondria play in autism spectrum disorders (ASD). The diagnosis of mitochondrial disorder or dysfunction is difficult. Multiple tests, often including an invasive muscle biopsy, are required.  How many other individuals with autism might benefit from a deeper understanding of how their cells use energy?

A new study released today in the Journal of the American Medical Association (JAMA) reveals that children with autism may have more trouble fueling the energy demands of their cells due to dysfunctional mitochondria. In this new Autism Speaks-funded study from UC Davis, blood samples from 10 children between the ages 2 and 5 years old and diagnosed with autism were compared with matched control samples from typically developing children.  The investigators found evidence of “breaks” in the cascade of enzymes that mitochondria use to create energy in 8 of 10 autism samples, but no control samples.  They found evidence of a mutation in a gene that supports mitochondrial function, also only in the autism samples. Lastly, in most of the autism samples, there were extra copies of mitochondria. The over-proliferation of mitochondria may also be a sign that individually the mitochondria are not working optimally, and are compensating for reduced function from each mitochondrion by producing more mitochondria overall.

Previous studies have shown that breaks in mitochondrial function can lead to a host of disorders, and the energy-demanding brain can be particularly affected. However, none of the previous autism studies has shown as high a proportion of impaired mitochondrial function as the current study.  Cecilia Giulivi, Ph.D., the lead researcher on the study and a professor of Molecular Biosciences in the School of Veterinary Medicine at UC Davis, was drawn to research abnormal energy metabolism in autism because several symptoms of ASD overlap with mitochondrial diseases.

“We wanted to test the hypothesis in a direct way: is there a mitochondrial dysfunction in material readily available from children with full autism syndrome?” says Giulivi. The research team chose to look at white blood cells—lymphocytes—because they are a type of cell that has significant quantities of mitochondria. Drawing blood is much less invasive than obtaining a muscle biopsy, but traditionally mitochondrial function has been difficult to assess in blood because there are relatively few mitochondria in blood, compared with other body tissues. In fact, red blood cells have no mitochondria at all.

While these results are an exciting new development for both this area of research and for families, it is important to remember that this is still the edge of science and not yet a clinically-useful set of tests. However, if replicated, these tests could make screening for mitochondrial dysfunction much more accessible.

Dr. Giulivi and colleagues are already taking the next steps to follow up this research.  They are studying the families of children with autism to try to understand the mechanism that causes the mitochondrial deficiency. The samples are part of a larger study (CHARGE; Childhood Autism Risks from Genetics and the Environment) in which the investigators are already measuring both genetic and environmental influences on autism risk.  Adding mitochondria to that mix will be especially helpful.  Dr. Giulivi was also quick to add a note of deep appreciation for all the families that participated in the study, saying “Without their participation, we couldn’t have done it!”

Indeed the enthusiasm for research participation often works both ways.  The seizure medication Levi had been taking—Depakote—seemed to make Levi very drowsy. At three years old, Levi was sleeping and napping for 16 hours of the day. His mitochondrial specialist switched medication right away due to concern of an underlying mitochondrial disorder for which Depakote produced severe side effects.

The Jensens are thrilled to report that Levi now has more energy than ever, has regained words that he lost prior to the medication change, and is generally functioning at a much higher level.  For Levi’s parents, Curtis and Alaina Jensen, learning about Levi’s mitochondrial disease helped them gain an understanding of metabolic functions and sparked creative ways to make special considerations for the remaining challenges Levi faced.  Alaina says, “We have found that exercise has been a big key for Levi to feel good and increase his energy and stamina.  It took a long time for him to build up the endurance to play, but it has been worth all the effort.  With a combination of the right seizure medication, supplements, exercise and diet, we now have a very happy boy.”

Autism Talk TV – Episode 11

November 29, 2010 1 comment

This is a guest post by Alex Plank, an autistic adult who founded the online community Wrong Planet. Alex is a graduate of George Mason University.

If You Could Say it in Words is a great new film about an autistic protagonist Nelson and his experience with love. The film came out on DVD yesterday, November 23, 2010. In this episode of Autism Talk TV, I switch sides of the camera and get interviewed along with director Nicholas Gray and actors Alvin Keith and Marin Ireland about the project. Nicholas has graciously offered to allow approved nonprofits to screen the film for for benefits and community events.

I first learned about If You Could Say it in Words in October of 2006. I was contacted by the director, Nicholas Gray, who had found my interview of Heather Kuzmich from America’s Next Top Model.

After getting the chance to watch the film, I was very excited. I interviewed Nicholas, and actor Alvin Keith, at my home in Virginia. Shortly after the interview was published, I posted a review of the movie to Wrong Planet, in which I described the film as having “the most authentic portrayal of an autistic person that I’ve ever seen in the movies.” After I had posted these two articles to Wrong Planet, director Nicholas Gray and I became friends. Needless to say, I was very happy when he called me and told me that he had secured a distributor for the film.

Nicholas licensed my documentary ‘autism reality’ to include in the special features of the DVD for If You Could Say it in Words. In addition, he asked me to produce a documentary about the plight of the undiagnosed Aspie.

Nicholas has graciously offered to allow approved nonprofits to screen the film for community events. Some nonprofits have already taken advantage of this program. You can contactAdam Eisenstein if your organization is interested showing If You Could Say it in Words at one of your events. Contact aeisenstein@chipchair.com for more information.

Now, please enjoy episode 11 of Autism Talk TV!

Autism Speaks Calls on the National Community to Join Michigan Lt. Governor-Elect Brian Calley to “No Longer Remain Silent” on Autism Insurance Reform

Nation, families in Michigan need your help today to get autism insurance reform passed before the end of their session and to become the 24th state to pass this legislation.  After four years, Michigan stands poised to finally join nearly half of the country in passing autism insurance reform legislation. The House has already passed the bill, but the State Senate must take up this issue before the end of the legislative session this week.

We are asking the national autism community to come together in support of this effort on behalf of Michigan families by taking just five minutes to call Michigan State Senate Majority Leader Mike Bishop at (517) 373-2417. Urge him to please bring autism insurance reform to the floor for a vote before the end of the legislative session.

Michigan Lt. Governor-Elect Brian Calley and father of a daughter with autism has been an outspoken supporter of the autism insurance reform effort in the state. Watch his video and share it with friends across the country.  Together we can join Lt. Governor-Elect Calley in saying “We will no longer remain silent.”

AutismCares this Holiday Season

November 29, 2010 Leave a comment

In times of economic hardship, families with one or more children with autism are among those hit the hardest.  In addition to the high costs and stress associated with caring for a child with autism, a sudden job loss, accident, home foreclosure, or natural disaster makes an already stressful situation worse.  When social services, family and friends, and loans run out, where do these families turn?

AutismCares helps families affected by autism to cover costs associated with critical living expenses such as: housing, utilities, car repair, daycare, funeral expenses, and other essential items on a case-by-case basis. The program relies on donations to assist these families who are in need.

During the holiday season, hardship is felt even more for these families and we need your help to continue to be able to provide much needed assistance for the community!

Get the Full View With Autism360!

November 23, 2010 9 comments

Lauren Brumbach Rothermel has two sons, 12 and 5, the older of which was diagnosed with PDD-NOS in 2000.  Shortly after his diagnosis in December, Lauren visited a DAN! Doctor, started him on the GF/CF diet and began intensive ABA.  She continues to work closely with physicians and other experts in trying new methodologies related to finding a cure for autism. She also served as president of the Berks Autism Society and spearheaded the first Walk for Autism Awareness in Berks County, that is in its 8th year.

I’d like to introduce you to a new website, Autism360.org.  Autism360 is a web-based tool for parents of autistic children.  This website gives parents the ability to build a profile of their child and compare their child to others.  This tool actually clusters children who share similar characteristics.  The best part is that you can see which treatment options seem to work best for children who look like your child.  You can then discuss these treatments with your health care providers or try them on your own.

Initially, basic information needs to be entered into the site to set up your child’s profile. You will add things like height and weight.  The next step asks you to enter specific information and history on your child.  When you are finished, you can do two things.  Click on “others like me” to see a cluster of children like your own.  This will show you the treatments that have worked and not worked for this group of children. You can also “generate a report”.  This is especially useful for therapists, doctors and anyone working with your child.

My son is now twelve years old.  I really wish I had a web tool such as Autism360 to use when he was first diagnosed.  I remember feeling completely alone and worried that I was the only one who was experiencing these new things.  Autism360 connects you to other children just like your child.  You learn that your child is not the “only one” and begin to feel much more connected. And you get some useful  ideas about treatment options.

I worked on inputting my son’s data one night after the kids went to bed.  It was very easy to do.  The great thing about Autism360 is that it saves all of your child’s information so you can come back to it later on. It is completely confidential and will generate reports for you so you don’t have to create them yourself!  Plus, it’s totally free and we love that!

I urge you to give it a try, you won’t be sorry!

Team Up With Autism Speaks has an Outstanding Year of Fundraising

November 22, 2010 2 comments

Seven thousand two hundred fifty nine point four (7,259.4) miles. That’s how many miles Team Up with Autism Speaks members covered in 2010 to raise autism awareness and funds to support the mission of Autism Speaks. In 2010, Team Up fielded teams with guaranteed entries in  events; 2010 Walt Disney World Marathon Weekend, 2010 TD Five Borough Bike Tour, 2010 Chicago Half Marathon, 2010 Bank of America Chicago Marathon, and the ING NYC Marathon 2010. These teams have combined to raise over $776,583. Other Team Up participants competed on their own in endurance events across the country. Overall since 2007, when Team Up was established, our teams have raised over $1.7million to support the mission of Autism Speaks.

Many members of Team Up with Autism Speaks teams didn’t meet until the night before the race, but they ran as a team, united by their commitment to the cause, and their commitment to their children, brothers, sisters, neighbors and friends affected by autism. Every member of Team Up has a story worth telling. Here are a few we would like to share.

Katie Baranek and her boyfriend, Bill Shaffer, trained together and fundraised together. Katie’s family traveled to New York City to cheer them on as they ran the Marathon for her brother Hunter and sister Hayley. Katie and Bill also ran with our 2009 Chicago Marathon team and Katie will be running with our ING Miami Marathon team in 2011. “Running as a member of Team Autism Speaks has been such a great experience and I have been lucky to have been a part of the team for three marathons and three years in a row. I love to run in marathons, but it is so much more special when you run FOR something. I run for Autism Speaks in honor of my little brother and sister, who both have forms of autism and running has given me the chance to not just raise funds for autism, but to also raise awareness within my family, friends and community. Being a member of Team Autism Speaks has given me the opportunity to do something positive with each and every stride I take.”

Don Croteau started running on a treadmill, two to three miles just for some exercise. He then started stretching out his runs. After about three months, he was running 5-6 miles at a time, which he thought was his limit. But when he saw that Autism Speaks had a charity team in the 2010 Disney Marathon, he immediately registered for the half marathon and started training. Don has a beautiful blonde little friend, Molly, who has autism and knows several other families who are struggling with young children on the spectrum. He saw this as a true sign and as a way to anonymously support these wonderful children and their hard working, dedicated families. He also saw it as a way to give back some of his time and good fortune to a very worthy cause, and to give him strength and motivation when he needed it. Don ran for Autism Speaks in the 2010 ING NYC Marathon and is returning to the Disney run in 2011. More icing on the cake for Don, is that he is a slim 185 pounds now, down from 320 pounds. The evening prior to the NYC Marathon Autism Speaks President Mark Roithmayr asked Don why he ran for us. Don looked at him and quietly said…“running for Molly and Autism Speaks just makes me a better man.”

Sisters share a strong bond and this is no different for Meg Brossy and Molly Shirer, two of our NYC Marathon team members. But it is their love for Willie, Molly’s 19 year old son with autism that brought them to the city of New York to endure what most only dream of. Side by side every step of the way it took them seven hours and 17 minutes to complete the 26.2 mile journey for Willie. Molly beamed after her accomplishment saying “Willie is 19 and in early adulthood. I am realizing that he needs to take more steps towards being physically fit. I am determined now to make a “power-walker” out of him. He always attends the annual San Diego Autism Speaks Walks with me and seems to greatly enjoy the experience!”

These stories inspire us all to get up, lace up, and get moving. Team Up with Autism Speaks has limited entries into over 13 events in 2011. It is easy to join and we have a support team for you every step of the way as you strive to reach each of your goals. In 2011, Team Up has the opportunity to cover over 17,000 miles to raise awareness and funds.

How many miles will you cover?
